Customer Reviews

Calm and Relaxing
I had taken this a few years back but recently due to job stress I felt my husband needed this. He now takes it daily and it has helped him continue working. It gives him calmness to accept the changes he has to cope with daily at his job. This arrived within just a few days and we have used it--both of us-- 2-3 times daily.*

Saves a ton of $$$
My husband and I are on L Theanine as a supplement ordered by our doctor. The amounts we have to take are cost prohibitive at most sites. This site has larger sizes and better prices than most other places to buy the supplement. The order came quickly and we are pleased with the quality.*

Blends well with coffee
I ad this to my coffee or tea daily. I dont even notice I added it. I haven't had this long enough to say it works.... but so far so good*

On 2/9/2019 Regina said...

Hey guys,

If you want something to help relax and fall asleep without waking up feeling groggy then look no further. It really does work but start small and work your way up like usual. Good for anxiety and sleep and for some...better mood

Hope this help*

Great Supplement to Coffee
I have purchased L-Theanine Pure Powder before from other vendors and was really delighted to find BulkSupplements had it in stock. I am a coffee lover but over the years I found tea worked better for me at work because of the synergy of the combination of Caffeine and L Theanine. The combination allowed the benefits of Caffeine but without the jitters & anxiety. After finding L-Theanine Powder supplement I now have switched back to coffee & add L-Theanine to my coffee at the recommended 1:2 ratio (1 part Caffeine: 2 parts L-Theanine). Combined, caffeine and L-theanine work better together.

the best l-theanine I've found
L-theanine helps reduce anxiety, and also curbs sugar cravings, and BulkSupplements' l-theanine is the best I've found!*

On 11/15/2018 Elizabeth said...

Works For Me
This l-theanine powder has a fine consistency like flour. It is tasteless and mixes easily in tea or coffee.

I have taken 200-500mg in a single dose without any side effects. I have taken 1 gram total in a single day, also without any side effects. The measuring guidelines on the package is pretty accurate as I checked against my own digital scale.

L-theanine gives me a calm sensation that washes over me within 15 minutes. I always take it with tea or coffee, never by itself.*

Fireplace Flame
I heard Theanin and other supplements from a friend of mine and did a comprehensive search. To be honest I didn't believe aforesaid effects about theanine in several sources but right after trying regularly I felt blood which penetrates correctly to all my veins. I felt the blood even on my ears and cheek, I felt energetic and dynamic. From my deep research, I might recommend to add it in day's first coffee on an empty stomach. *

Great product
This product is as pure as it gets and very potent. I will definitely re order when I run out. Bulk supplements is the best for high quality products at a low price! *

l-theanine powder
L-theanine is an excellent supplement with a multitude of health benefits. The powder form offered by BS is an excellent product, with no fillers, and exceptional value. Highly recommended!!*

On 10/25/2018 Joe from AK said...

Didn't "feel it" but seems like quality powder
Well, I have only been taking this for almost 2 weeks, so it's probably not long enough to fully write it off. But I'm going to keep taking it because it's proven to have some neuroprotective effects, and help with calming the brain in preparation for sleep. That's critical in our melatonin-wrecking environment of today.

As for the powder, it seemed to be high quality. Very dry, sealed well, and it had that slightly sweet taste that L-Theanine is supposed to have.

I would recommend the value of this product if you're going to be making your own supplement caps.*

On 10/24/2018 Robert said...

Awake brain
I usually try a new supplement alone just to see how my body reacts to it. After reading about L-Theanine I wanted to try it for my nootropic mix and also for meditation. Supposedly it helps induce an alpha state of calm, relaxed alertness. It definitely did that for me!

I noticed energy moving in my head after a minute of taking it sublingually. Then I felt more alert yet calm. It made for a great meditation and helped me stay in the zone the rest of the day.

Definitely a reorder!*

On 10/11/2018 Court said...

Amazing with coffee
I mix this with my coffee and the effects are noticeable after the first use. I get the same energy that I normally get with caffeine, but without the jitters and anxiety. I feel like I'm a lot more focused than I am normally with just coffee by itself as well. I'm definitely ordering this stuff again.*

On 10/2/2018 Req said...

I bought this product along with tryptophan to assist in sleep and I can only say it’s wonderful. It doesn’t give me the hangover normally received from melatonin and I sleep great. *

On 9/29/2018 Jess said...

Great sleep
I have only been taking it fir a few days but on day 2 my sleeo was deeper and I was more relaxed in the morning and throughout the day. I think I'm gonna like it, it seems to work.*

Great Deal
I used Theanine for a while and this is a great deal. Get more than twice the normal dose for a lot less. The only way to buy if you are a regular user.*

Quick Calming
This is a wonderful amino acid!! I read an article about it and then ordered it from Bulk Supplements! This is the real deal to take the edge off stress!! I use it regularly when multi-tasking and in those mystery sped up moods! It works all the time! LOVE L-Thinine!!!!*

On 8/29/2018 Craig said...

Great stuff!!!
At night I take about 800mg of L-theanine along with passion fruit powder. WORKS like a charm! I sleep pretty much through the night for at least 7 hours straight!

On 8/23/2018 Corinne said...

Great for anxiety and alcohol cravings
This is my second time ordering L-Theanine from BulkSupplements. I haven't had a panic attack in over six months, and I'm "nicer" according to my husband. I've become an L-Theanine cheerleader at work, and colleagues overwhelmed with stress frequently get handed a small glass of water--"Here, drink this, it'll make you feel better!" I always have at least two bottles of L-Theanine water with me when I'm in court, one for me and one for my client. Speaking of clients, I tell them to order L-Theanine from BulkSupplements (and also Ashwagandha, Passionflower, Magnesium Glycinate, L-Glutamine, Glycine, and L-Tryptophan.) Everyone who starts taking L-Theanine has a relatively easy time getting sober and staying sober. Thanks, BulkSupplements, for providing products of consistently high quality. I'll always be a 100% happy customer!*

On 8/16/2018 Heather said...

L Theanine..more sociable?
A while back, I took L Theanine caps and felt calmer. Then like most of us I moved on and forgot about it as the need diminished. When I recently did research on how L Theanine helps prevent blood pressure spikes, I decided to order it from Bulk Supplements. I read a testimonial how it helped an autistic person be more sociable..I thought thats wonderful. Little did I know that I too feel more sociable after taking L Theanine. Amazing!*

On 8/6/2018 Darryl said...

Effective, might not be clean though
The L-Theanine I received surely does its' job and the price is unmatchable. Best bang for your buck. My only concern is that people all over the internet are reporting it to be contaminated with lead and having a weird chemical/metallic smell to it. I cannot confirm this is true, but it does concern me and the claim is coming from multiple sources. Other than that it's great!*

On 8/1/2018 Dominic said...

very bright eyed
I take 200mgs 3 times a day. In the morning with my coffee, in the afternoon with a caffeine tablet and by itself in the evening. It leaves me very sharp, upbeat and energized with out that wired stimulated vibe. I have no problem going to sleep and I'm not sure but think I the quality of my dreams has improved *

On 7/17/2018 Robert said...

good quality
I received this complimentary 50g bag to try out. I added 250mg per serving with my custom preworkout mixture. It helps achieve mental clarity and focus for my workout without any jitters. *

On 7/17/2018 ryan said...

I use this product as a pre-workout supplement along with my BCAA's and AA's. It has helped me focus on my workouts. My wife and I also take it for its sleep restoration effects. Bulk Supplements is at the supplement forefront. *

Excellent results!
I'm amazed with this amino acid! I read about it on Dr. Andrew Weil's website! Very calming effect, and fast acting! I no longer get too wired up after coffee. Helps my focus on tasks!! I take it in the morning and works all day! This is the best calming supplement I've found!!

On 2/5/2018 nelida correa said...

Good so far
Mixes well with whatever you're using. Haven't noticed a huge effect but it does seem to take the edge off a bit.*

On 1/31/2018 Jeff said...

Quality Purchase
I have tried a few other brands of L-Theanine before, mostly from grocery stores and vitamin shops. The consistency of this L-Theanine is truly awesome. It dissolves quick and well in water, fluffy (non-crystaline), and surprisingly tastes good! I've paid the same price for 100 grams that I have for 5 grams elsewhere, and the quality is much better too. 5 stars.*

On 12/1/2017 Dominic said...

L-Theanine is fantastic!
L-Theanine is such fantastic stuff! It's very calming without being in the least bit sedating, and I've never noticed any side effects or after effects. It goes super well with coffee, as the caffeine potentiates its effects.

L-Theanine is perfect for very energetic, passionate individuals who want to "take off some of the edge", while maintaining their high enthusiasm. It's particularly perfect to take when one plans to socialize a lot (i.e. before a date, or before a party, business event, or family event). In other words, it takes away most of your anxieties, while maintaining a very pleasant, highly energetic, socially engaging, yet calm, sober mood.

Interesting observation....I know someone who has been diagnosed by a psychiatrist as being on the autism spectrum, who upon taking a standard dose of L-Theanine, briefly "came out of his shell", and was remarkably engaged in a normal conversation. His family was floored to watch him engage in conversations and to "be present". His mother was in tears. I gave him half of my l-theanine supply; he takes it twice a day, and he now has a girlfriend!

While I am not a doctor, as a lay person, I must mention that this observation is remarkable, and I hope that more people take note of this....L-theanine helps people to engage in healthy social activity, and it increases healthy extroversion. I've told several friends of mine who are psychiatrists and neurologists to take note. It's not surprising that green tea, from which l-theanine comes, has been so popular throughout history.*

BEST with 5HTP and N acetyl L Theanine
For a pure no nonsense anti depressant, I take before bed a combination of the L Theanine, 5HTP, and N-acetyl L Tyrosine. I have been taking this now for about 3 weeks and notice a huge difference in mood and outlook on life! WOW!!!!!! Bulk Supplements is the BEST source for pure, natural, no-additives powders! Thank you so much!!!!!!1*

L-theanine is a lifesaver!
This stuff is essential for me. my psychiatrist prescribed it years ago, but she said that sadly I must get it on my own OTC. Out of all the hundreds of meds I have tried, this is the only one that really worked. It saved my life. Paranoia 100 - 0% after .5 - 1g sublingual EVERY TIME I USE IT ... PERIOD!! Benzodiazepine is a joke compared to theanine. The dose required for me is drastically larger than anything I have read about in the scientific literature; nonetheless, this chemical is an absolute godsend. It works within minutes, it works everytime, everyday, throughout the years. I take it at least every four hours under the tongue. I wake up in the night and must take it to get to sleep again (the paranoia keeps me up and causes severe stress that is almost painful). With the help of theanine, I went from bottom of the barrel bed-ridden mental defect -- to studying medicine and excelling beyond my peers. The packaging was leaky, the powder seeped out of the damaged ziplock that it came in. The product is slightly contaminated with a harmless drying agent of volatile nature, but this contaminant evaporates out of the theanine after opening and reopening the bag 10 or 20 times. Overall, I could not find a Theanine for a better price. BONUS- THIS COMPANY PROUDLY DECLARES THIS PRODUCT IS VEGAN!! (I refuse to cause harm to myself and others by allowing non-vegans to get any of my money)*

On 8/9/2017 michael said...

Great preworkout and before bed
As someone sensitive to caffeine its nice to find a product that prevents the jittery feeling that comes along with it. I've been using 250mg along with 200-250mg in my preworkout and it works great! Pairing it with phenibut and 5-htp before bed has improved my sleep quality as well. You'll most likely need to find a 1/8 tsp measuring spoon though but unfortunately, they're fairly common. Overall, it's wonderful and versatile product at a great price for how many servings in it. *

On 7/15/2017 Patrick said...

Great product
I use L-Theanine along with my other sleep helper agent which gives me a quality sleep that I need. I don't have nightmares anymore.*

On 7/10/2017 Henry said...

Good But Funny Smell
Good price. Theanine helps me with anxiety and more instability from my bipolar disorder. This batch has a strange odor though that I haven't experienced in the past. I would still buy again though.

On 6/30/2017 Michael said...

I got this to promote better sleep at night in larger doses and reduce anxiety in the day with smaller doses. Hardly any supplements that I have bought over last several years did much. This one works day and night. really improved my sleep and lowered anxiety in the day.


On 6/22/2017 Jason said...

good product
I have been taking this product for several months. It was recommended to me by my nurse practitioner to help with adrenal fatigue. It works within 30 minutes to an hour taken on an empty stomach (which if needs to be) and I can really tell a difference. It helps alleviate anxiety while giving a non-jittery energy that I need. Very effective. I take about 200mg 3-4 times a day. I would recommend it to anyone who needs to decrease anxiety or stress while simultaneously increasing energy level. I was buying the capsules locally but ordered here because I could get a huge savings on cost. Thanks bulk supplements. It's my first time to order here but I'll be back!*

Combine with caffeine for clear focus; no jitters
Theanine is great to combine with caffeine so as to give a clear focus while using caffeine but none of the jitters you can get. As always, experiment to find the right dosage for you but I can tell you it's nice to have a lot of energy but not act like unfocused OCD nut because I only used caffeine alone.*

Works fine
I have a 250mg caffeine pill and I use ~200mg of L-Theanine powder as a mix.

Very good product.*

Stops mind from racing when trying to fall asleep
Just recently purchased the L-Theanine from Bulk supplements. I've been taking store brands for years as needed, but I love the price and purity (and no additives) with this product.

Takes the edge off a stressful day.
I work as a Wellness Specialist at a large international anti-aging and wellness company. I am very picky about what I put into myself. In the process of trying to customize a pre-workout for myself, I came across BulkSupplements. I have been pleased with the quality of these supplements and appreciate there is nothing added to them. The products I have been purchasing from bulk supplements I actually am able to obtain for a lower price than my excellent employee discount gets me from my employer. I have since began to suggest products from bulk supplements to my customers when appropriate. In a world of adulterated and questionable supplements, it is nice to have found another company that I trust for quality and purity. I recently purchased the l-theanine because of the excellent price. I am pleased with this product as well. It is supportive of restful sleep and can help take the edge off a stressful day.*

This l-theanine is unparalleled in quality. It mixes easily, has virtually no taste, and seems more potent (at equivalent milligram doses) than other L-theanine products I have used.

L-theanine helps me cope with the rigors of a hectic work/school life. When using L-theanine, I maintain a more level head and can concentrate with less fatigue and burnout. I generally take a small dose with my morning coffee and a small (but slightly larger) dose before bed. Awesome nootropic. .

A quick thank you is necessary, as bulk-supplements provides an excellent quality product at an unbeatable price. *

Bulk powder adds convenience to a great supplement
I have used L-Theanine for both myself and my dogs for several years. It helps to improve focus and quiet my racing thoughts, my dogs are less reactive to the unpredictable sounds of the world which reduces their stress. Every three weeks or so, I mix several supplements into pumpkin puree and freeze it into ice cubes for one of my dogs. It is so easy and fast to weigh the correct amount from the bulk powder for him vs opening all the capsules. I am in the process of converting as many of his capsulated products to bulk powder as possible. Thanks Bulk Supplements! *

Great Product!!
L-Theanine is the best way for me to get the mental focus and sleep I need. This product is also great for reducing stress. Great costumer service and fast shipping! *

Great Product, take when feeling anxious or stressed and really produces a sense of relaxation and calmness. Recommend this product highly for everyone!*

On 6/7/2016 Lawrence said...

GOOD for alertness and focus without the buzz
Fast shipment! L-Theanine works within an hour - calms me during stressful situations... I'm not so grouchy! I haven't tried it for sleep, just for calm in the morning and throughout the day. I take a scant 1/16 tsp in the morning and I'm good to go! If you have the set of tad, smidgen, drop, pinch, dash teaspoons, use the "pinch" - that equals 1/16 tsp, or 121mg... using a scant pinch spoon will be approximately 100mg! *

I am postmenopausal and have had sleep problems for years. I take this along with l-tyrosine, phytosterol, and ashwagandha about 30-40 minutes before bed and it knocks me out. Finally, I'm getting a good night's sleep!*

On 4/5/2016 Jennifer said...

Caffeine Optimized
L-Theanine is the perfect way to get the mental stimulant hit of caffeine (or other stimulants) while avoiding the resultant anxiety and blood pressure spikes. Also a very helpful sleep aid, if you're an anxious sleeper.*

Great relax and sleep aid.
Sleep is one of three of the major components in building good quality muscle. You can lift all the weights in the gym, but if you don’t sleep, you won’t grow, it’s that simple. L-Theanine Is a good quality multi-benefit sleep aid/stress reliever.*

L-Theanine powder Wow!
My 92 year old Mother-in-Law, suffering the effects of long term antidepressant use, including sleepless nights. She agreed to try to get off them. In an effort to help her with that, we gave her the following:
D3, Krill oil, Rhodiola Rosea, Alpha GTC, Pyridoxine, B12 spray, Thiamin, L-phenylalanine, 5-HTP, and L-theanine.

She responded well, but when we added the L-Theanine (last to arrive), she had marked improvement in her sleep and mood. Definitely worth noting! *

On 3/23/2016 gordon said...

This L-theanine was provided as a free sample in exchange for another review. So far, after only a few trials, we both found the L-theanine had an immediate calming effect, with increased feeling of tension later. Perhaps the L-theanine will be more continuously helpful if taken every few hours. Pure product, fast shipment. Bulk Supplements' customer service was outstanding as always!*

On 3/19/2016 Jonathan said...

I chose this product as my free sample. I've been interested in theanine since researching its cortisol lowering ability. I've been taking it on workout days and it definitely helps me relax and recover quicker from workouts!!*

Bulk is a great company and their customer service is awsome as well. Thank you!*

L-Theanine Powder, A Great Product!
As always, Bulk Supplements has surpassed my expectations of service and product quality wow! I am impressed with the quality of the product and how it lives up to the other customer reviews.

I have had difficulties all of my adult life with sleeping and being able to relax when I go to bed. I need to take a sleep aid before I go to bed to be able to sleep even for a few short hours. I have found that if I take the L-Theanine (242mg) about an hour before I take the sleep aid I fall asleep much sooner. If a person has difficulties sleeping it is amazing how much help a few minutes can be.

I would highly recommend this product. I find that it meets my needs and I will add it to my future orders. It is my hope that I can get off the prescription sleep aid and use the L-Theanine.*

On 2/27/2016 Robert said...

This product is great in my post workout shake. I workout early in the morning and I'm caffeine sensitive. The theanine helps me to focus at work and stay on task.*

On 2/16/2016 John said...

Seems to work well
I've used this powder in the morning as well as at night for sleep. I do seem to feel more willing to get out and do things that usually bother me and I'm definitely sleeping better. The affects are very subtle but seem to be real.*

On 1/27/2016 Bill said...

I received a complimentary supply of L-Theanine for a recent review of Bulksupplements Rhodiola Rosea. I have only been taking the L-Theanine for ten days, but I can assure you I am already feeling the results. There are many other Bulksupplement products that I am anxious to try. I have complete confidence in BS products. I highly recommend. *

On 12/26/2015 Jack said...

great sleep aid. I had been having trouble sleeping and this has done the trick. I sleep soundly throughout the night and wake feeling refreshed.
I recommend this to everyone.*

On 12/24/2015 Paul said...

Repeat Customer for a reason
I have ordered my Theanine from here multiple times, and will continue to do so in the future. The powder is accurately measured with every bag I have received after multiple weight tests on several analytic balances and digital scales accurate to .0001g ±.0001. Without doing a spectrum analysis on the powder I cannot attest to the purity, however I have always felt as though the effects have been substantial for what they are, and believe this to be a quality product.

I personally dose 200mg along with Caffeine twice per day to help with focus and mental stamina. I feel that it greatly helps. *

On 12/12/2015 Alex Jacobsen said...

Works as advertised
The powder is very clumpy but that's because it has no fillers! Theanine works great for calming/sleep! Product was shipped fast and in a responsible packaging! *

This is the second time i re-order this product it is great and pure from Bulk Supplements will not buy from other place full with additive do your research thank you Bulk Supplements for your fast and great service*

On 11/14/2015 Deva T said...

Excellent Product
Product arrived as described and worked as well as expected. There is really nothing better I can say about it! One caveat (although this may be a limitation of the product itself and not the manufacturing) was that the powder tends to clump up, making it a little difficult to combine evenly with other products without breaking up the clumps manually (very tedious to do). Again, not sure if that's due to how it is prepared or a property of the substance itself, just something I noticed.

I would not hesitate to recommend this product to anyone and have already ordered again!*

On 9/19/2015 Curtis said...

I had been looking for my usual coffee that had this in it, only I couldn't find the coffee anywhere. I drank this coffee when in school and it helped tremendously when studying. I decided I needed to find some and add it to my coffee on my own. Man was I ever excited to find Bulk Supplements and the L-THEANINE in a powder! On top of finding it I also found that I couldn't have asked for more from a company: dosage information, nutritional information, and made in a way that so totally agrees with me. Let's not forget pricing, delivery, and packaging! I decided not only to share what I had bought with a few family and friends, but I also happily shared the website so they could look for their own needs.
The reviews were also a godsend. Hearing other people tout the product and company made me feel good about diving in on a larger scale from the first, instead of going with a smaller size to "see" for myself.
I have now been using this every morning in my coffee and find that I am getting the results I had been hoping for; awake all day sitting in front of a computer doing monotonous work, energy to do the things I had been putting off, and FOCUS! I will be continuing to order from them but it will be awhile before I finish my L-THEANINE. This powder form is truly perfect for my needs and its ease of use makes me smile.
I shared some with my best friend who suffers from anxiety and after adjusting her dosage says its working wonderfully for her focus and anxiety.
My youngest son has started taking it and after a couple of days I got to ask him what he thought, a man of few words "Can you keep me stocked?"
I can't say enough good about both the product and the company.*

On 8/22/2015 Danica said...

Great Product
This supplement doesn't give me a "feeling" per se. I've been under tons of stress lately switching jobs, and as a result, I've been biting down real hard due to anxiety. I've had anxiety problems in the past. I catch myself biting down and stop, but most of the time the damage is done and my teeth hurt for the rest of the day. After starting this supplement, once in the morning and again in the afternoon, I've noticed that I don't bite down at all. I don't feel zoned out or lethargic, but it seems the stress doesn't effect me physically. Mentally, my mind no longer races and it seems easier to think through my situation productively and calmly, whereas before I would just focus on the problem and not the solution - leading to more stress and confusion.
The people here at bulk supplements have really helped me more than they even know, and as a result, I've told anyone who will listen about this website. Sometimes the timing of things is just so perfect. Thanks again, Bulk Supplements. Two thumbs up!*

Works beautifully to take the edge off caffeine
I purchased L-theanine to complement the caffeine anhydrous from Bulk Supplements and their products work fantastically to increase energy and keep focus.

I don't have a pill capper yet, so I just mix my powders in a little shot glass with water. The caffeine/theanine mixture doesn't have a bad taste, at least, not compared to piracetam and choline.

I ordered on a Friday, selected standard shipping, and received my order on Monday. Phenomenal! And really cheap! *

On 6/3/2015 Kelly said...

Fantastic Product
I work in a very stressful position, one that demands a lot of concentration and effort. I try to balance it out with running and lifting. The combination of L-Theanine and Phenibut is extremely helpful in handling stress, anxiety and depression. It also gives a boost of energy, helping my workout when I'm tempted to say, "I just don't feel like it." Try it. *

L-Theanine helps keep my immune system healthy after the stress of running five fifty-second sprints in the mornings
First I want to say that according to the BulkSupplements website this l-theanine is rated US Pharmaceutical grade, a very high grade of purity (higher than food grade). This US-based purity test assures that regardless of the circumstances of the origin and manufacture of this l-theanine that purity problems of any kind should be extremely unlikely.

I run five fifty-second sprints in the mornings. Over the past year I have gotten bad colds lasting over two weeks several times. I figured it was due to exercising too hard. I have progressively cut back from eight fifty-second sprints seven days a week to five fifty-second sprints three days a week. But even breathing through my nose the entire time while running I was still getting colds. Taking 0.6 grams of n-acetyl-l-cysteine (NAC) three times a day knocked out the colds and stopped most of the coughing and sniffling at the end of the runs as well. But the clinical trials (listed below) say the combination of cysteine and theanine should be even more effective.

One drawback of the l-theanine is that I no longer have that "extreme" feeling after exercising, a feeling that lasts all day. It was in anticipation of this extreme feeling that motivated me to exercise in the first place.

The following is a list of clinical trials, most double-blinded and placebo-controlled, recorded at the National Medical Library, MEDLINE, as abstracted by GreenMedInfo for l-theanine.

1. L-theanine supports immune function.
2. Cystine (a dipeptide of cysteine) and theanine supplementation restores high-Intensity resistance exercise-induced attenuation of natural killer cell activity in well-trained men.
3. The theanine content of tea may be responsible for it significantly increasing immune function in users, relative to coffee consumption.
4. L-cystine and l-theanine may contribute to enhancing the immune response against the H1N1 virus.
5. L-theanine reduces psychological and physiological stress responses.
6. A combination of Magnolia, Epimedium, Theanine, Beta Sitosterol, Phosphatidylcholine reduces serum cortisol responses to physical stress.
7. L-theanine appears to improve cognitive function in mice.
8. L-theanine protects against glutamate-induced excitotoxicity in a mouse model.
9. Theanine prevents memory impairment induced by repeated cerebral ischemia in rats.
10. Theanine suppresses oxygen-induced retinal neovascularization associated in a rat model of retinopathy.
11. L-theanine suppresses food intake in rats, and may lower insulin levels.
12. Theanine may assist in healthy brain function development in the offspring of those who consume it while lactating.
13. L-theanine attenuates beta-amyloid-induced cognitive dysfunction and neurotoxicity.
14. L-theanine provides neuroprotection against Parkinson's disease related pesticide neurotoxicants.
15. Theanine enhances the antitumor efficacy of chemotherapeutic agents.
16. Theanine inhibits the growth of leukemia and non-small cell lung cancer cells and enhances the anticancer activity of anticancer drugs.
17. Theanine inhibits the invasion of hepatoma cells.
18. Among healthcare workers for the elderly, taking green tea catechins and theanine may be effective prophylaxis for influenza infection.*

I found this product to be very calming. It eliminated racing thought which allowed me to relax and be more focused. I took 250mg, tid. I was able to watch a movie all the way through without distractions. I was able to fall asleep much more quickly. No taste. Mixed well with iced tea.*

Helps with focus and irritability
I mix l-theanine 1/8 tsp in my coffee every morning and it helps me feel calm, counteracts jitteriness from coffee, and improves focus. Sometimes I take a second dose in the evening if I am on edge or irritated and it helps with that also. Taking higher doses does not increase the effect for me.*

Increases focus, as well as helping me sleep better
This increases focus when I take it with caffeine, and it seems to reduce my ADD symptoms as well (I have been professionally diagnosed with adult ADD.) I also tend to fall asleep easier and wake up feeling more refreshed.

It doesn't mix easily with water unless I use a hand blender, but this isn't much of a problem. Once it dissolves, it dissolves completely--no powdery residue on the bottom of the glass. You can also mix it into food, it has a mild taste which is slightly sweet and slightly salty.*

On 4/2/2015 Paul said...

Definitely has a calming effect when taken daily. I am a full time student and it definitely helps.*

On 3/20/2015 John said...

Awesome Product! Quick Shipping!!
I have been taking theanine for about a week now. It seems to have tremendous effects (but still subtle) compared to GABA. L-Theanine easily crosses the blood brain barrier, unlike GABA, but has similar effects. It is perfect for my anxiety, fear of public speaking, and stress. Even better, it does not effect my performance at all. If anything, I can think more clearly. It does not slow you down cognitively like anti anxiety prescriptions, and does not make you sleepy (but definitely relaxed). I'm not a big tea drinker, so this is my alternative way of getting L-theanine. The product is great and I have had lightning fast delivery from this company 2 times now. I highly recommend it if you have anxiety or social phobia of any kind. Buy this now!*

On 3/3/2015 Ryan said...

Very high quality L-Theanine
I have taken 200mg of L-Theanine daily for quite a few years and the effects have been transformative. It calms my nerves leaving me in a pleasant and productive state of consciousness.

On 1/15/2015 Derek said...

I don't need that much of L-Theanine to feel its effects. Just 100 mg twice a day, usually morning and lunch gives me an alert feeling without putting me to sleep. Will continue use for a month or so to see if I want to add to my regime.*

On 12/22/2014 Paul said...

Highly effective product!
I have found that this product really does help to reduce anxiety, calm the mind, and allow me to focus for several hours. A large bolus taken at bedtime also puts me to sleep with relative ease, and doesn't seem to have the "hangover" effects that diphenhydramine or other antihistamines have. Will definitely consider this a staple in my supplement suite. *

On 12/18/2014 Michael said...

Multiple Beneficial Effects
I have been taking theanine for its little known anti-histamine action so that I can avoid otc anti-histamines that jack up your liver. The dopamine boosting effect is pretty sweet too. Unfortunately, the substance only has a half-life of 2-3 hours, so you do have to re-intake throughout the day. Great price here.*

On 12/8/2014 sean said...

Great for Anxiety and Pre-Workouts!
Bought this for both anxiety use as well as pre workout use when mixing with caffeine. I have suffered from anxiety for a few years and never liked taking benzos. This helps calm me and really work well with caffiene to take away the jitters! Mixes well and great price!*

On 12/5/2014 Mike said...

L-Theanine (50 g pure powder)
I work in the herbal health foods industry and have read a lot of positive articles about the benefits of L-Theanine, which is essentially highly concentrated green tea extract. It basically gives you a state of "calm focus" without any negative side effects. I've found the Bulk Supplements powder to be extremely fast-acting. I take it at work when I really need to focus and/or when I'm under stress. Great stuff. The company's trademark fast delivery sealed the deal. Will order again for sure.*

On 10/10/2014 Robert said...

Ultimate zen
If you want to remain calm and yet focused, this is the product! If you get nervous taking tests, speaking to groups or doing anything else where you need to be calm yet at the top of your game, this is the only product you need! Gives those taking it an 'unfair' advantage during tests. It allows you to access the information you have that is usually blocked by anxiety. Can't say enough about how great it is. I first tried it in pill form I bought at a vitamin shop - and paid 20 times what I did here. Thanks guys!*

On 9/29/2014 rich said...

It works great together with caffeine! It gets rid of all the negatives such as the jitters and the anxiety. *

Best L-theanine
I didn't buy this for a nootropic, I didn't even know about nootropics at the time I started taking this supplement two months ago. I was recommended to take it to help my body relax. I have a neurological pain disorder and have trouble relaxing as well as chronic pain. I can feel the relaxation wash through my body after taking 1/4 tsp, it helps me sleep and my pain has drasitically reduced. My cognition is doing better but not sure if it is just the L-theanine because I am doing a stack that has boosted my brain a lot. I really recommend BUlk supplements, not only are they fast at getting me the product but they are very fresh and their purity is unmatched. I had tried other L-theanine supplements but they all had cellulose added and did not benefit me at all. I am so grateful to have found this pure powder. I haven't needed pain medication since starting my stacks.*

On 8/23/2014 William said...

Great Nootropic
L-Theanine is a great nootropic, in other words, it helps with cognitive function. I've used it to take important exams and also as a part of a preworkout supplement. The mental clarity it gives me, coupled with caffeine is incredible. There are some days I go to gym after a long day at work, and Theanine delivers in getting me focused in ways that caffeine alone cannot do. My only gripe is that the powder is a bit on the sticky side. Think flour consistency instead of sugar. However, this is the nature of the compound, and NOT the manufacturer. This minor nuisance is far outweighed by Theanine's cognitive benefits. I'm definitely buying more. *

II need L-theanine for my anxiety
I've been spending a lot of money on L-thenine caps for months now.
I've found it really helps with my anxiety.
I use it with GABA and have been much more calm and stressfree since I've been using it.
To find a pure, high-quality L-theanine here for 1/10 of the price I'm paying for the pills is extraordinary!
I wish I'd know about Bulk Supplements a long time ago.
I'll be ordering a lot of other products in the future.

On 8/14/2014 Liz said...

I ordered this product not thinking it would have that much of an affect on my general mood but it has. I started taking it during the day and I am much more relaxed in general.*

On 8/8/2014 colby said...

Great stuff
If you're looking at getting this, it's highly likely you've done your research. Theanine is a great, natural relaxant. I sometimes mix it with caffeine to avoid feeling jittery, but usually just take it by itself in the morning and evening. I can hardly taste it even when mixed with just a few ounces of water. I actually didn't realize I had taken it before: I used to take melatonin while I was in college to make sure I got enough sleep, and the pills I took were a mix of melatonin and theanine. No ill effects after having used this product for several years on an almost daily basis.*

200mg to 600mg during the day/morning helps with anxiety.

same dose when combined with phenibut (bulk sup as well) will help with easing to sleep.*

High Quality
This is a high quality product - Pure, no fillers. I dose between 100 - 200mgs for nice relaxing effect that isn't over-sedating. Excellent customer service as well!*

I love it!
I am in college and I take this along with the caffeine powder Bulksupplements sells and it is the perfect combination, awake but not jittery. I put this in my drink and have it all day long. *
