this has been a key ingredient that helps patients

Works, With Caveats
As someone who is genetically predisposed towards having lower D2-type dopamine receptors, being able to supplement with a catecholamine precursor like L-Tyrosine or L-Dopa is a great help. L-Tyrosine however has an extremely long biological half life, and takes about 2 hours to peak in plasma and remains elevated in plasma for long periods of time;


therefore, take it only in the morning if you want uninterrupted sleep later that night. L-Tyrosine is suitable for boosting working memory and attentional capabilities, and it helps sustain detail-oriented attention, though I don't recommend it for creative or emotional work.

After L-Tyrosine becomes dopamine, it then degrades into norepinephrine and epinephrine, in that order. These 'adrenergic' hormones and neurotransmitters enable the acute stress response, which can be helpful in fighting chronic stress induced by low-level continuous cortisol release.

I consider this a minimum-effective dose supplement; take too much and you will likely experience some level of flat emotional affect (hard to feel any emotion) and other symptoms of stimulant use, such as suppressed appetite, and increased task-related anxiety (ie perfectionistic compulsions, etc). It dissolves well in water, is tasteless, and is cheap with no known side-effects. On balance, I recommend this supplier and this product. Experiment to find a dose that suits you.*

Better Mood & Energy!
This L-Tyrosine powder is the real deal. I can tell its good quality, I have Bipolar depression and I am trying to get off of my prescription meds. I take 12,000 mg or more of L -Tyrosine a day and I have never felt better!*

On 4/28/2018 Jasmin said...

I purchased this product in order to supplement for bodybuilding training.
I use it with other amino acid products. It boosts my energy for training. I train every day before work and I could not possibly do this type of regular training without these supplements. I use 1/2 tsp and it works very well.
The company is reliable and responsive to customers. I believe that anyone who places an order with this Bulk Supplements will be happy with the products and service. I highly recommend.purchasing supplements from Bulk Supplements.*

L-Tyrosine Powder
Excellent product, very high quality powder. Worked very well in my formulation. This vendor processing and shipping is excellent as well. I would highly recommend!*

On 12/12/2017 Giovanna said...

I tried this for the first time after reading the reviews about it helping boost energy and mental focus. I was optimistically skeptical.
I took the scant 1/4 tsp 400 mg.
It was like I had taken multiple espresso shots!
I took it in the a.m. on an empty stomach with my one cup of black tea.
Everybody responds differently, so I must just be more sensitive to it. I'll be cutting the dose in half, at least, and switching to decaf tea or Dandy Blend to avoid the somewhat unpleasant jittery sensation that accompanied the 400mg dose, which took several hours to pass.
So, I'd say this is potent and effective, I just need to reduce the dose.*

L-Tyrosine Powder
Excellent pre-workout supp. Dissolves easily in food or liquid and Is tasteless. Seems to be helping with my dopamine deficiency. Thanks again for yet another exceptional product!*

On 7/25/2017 Angela said...

mixes completely in liquid--no crunchy bits
This is a good product--mixes easily and thoroughly with water or other liquid. I have to take a LOT (3 T.per day) for the amino acid re-balancing protocol my ND has me on. A more expensive kind I was using before left a teaspoon of crunchy chalky bits at the bottom of the cup every time. Was so relieved to find a kind that suspends completely in liquid!

Agree with another reviewer that the re-sealable bag is not actually re-sealable. I spoon a goodly amount into a bowl first and measure it from there to keep the powder from jamming the seal but it still won't seal again reliably. So have to fold it over and use clothespins. *

Keeps me mentally alert
It seems to keep my mind a bit sharper, and slightly elevates my moods. I've been taking it for about a month now. I put some in my morning coffee, it's practically tasteless. Great product!*

Neurotransmitter Support
Great high quality product for the support of catecholamine synthesis (Dopamine, Norepinephrine, Epinephrine). I highly recommend. Just remember to balance with some 5-HTP for serotonin support. Balanced neurotransmitters for optimal mental/emotional functioning is the goal.*

On 4/12/2017 Curtis said...

Good product, wish bag it comes in was easier to seal
Found bulksupplements through,
they always seem to have pure and reputable products

My only knock is that I wish the sealable bag it comes in was actually sealable. Also kind of hard to measure out the proper dosage*

Product quickly arrived and the bag is self-standing for convenience. Product easily dissolved in warm water.*

Secrete Weapon for Finals, Etc.
This is my third Tyrosine Order from

As a law student, I use Tyrosine to study for finals or whenever life heats-up. It's a great way to keep-up when a 9-5 turns into a 5-9.

Also check out n-acyle-tyrosine ("NALT") for when life accelerates to redline. However, I've found that NALT can make me edgy and impatient and Tyrosine doesn't seem to have these effects. *

Noticing a Difference
I take quite a lot of supplements and herbal formulas, so sometimes it's difficult to know whether something is making a difference or not. I've waited a while to post this review, until I had a better idea how it's working for me. I have noticed an improvement in focus and mood, along with more energy during the day, and sleeping better at night. I attribute at least some of this to the tyrosine, and perhaps the phenylethylamine I've also started taking recently, and a self-made herbal formula. In any case, I'm happy I've added this to my regimen, and recommend it. *

Great Focus!

L-Tyrosine and Focus
I bought this product after reading about the increased focus generated by L-tyrosine supplementation. I've been using for the past few days to improve my focus at work and I have to say: this product did not let me down. I've increased the amount of things I get done by at least 50%. Very good product.*

This is the 3rd time I've ordered this product. LOVE IT! Mixes easily with anything, very pure (I requested the data on potency), tasteless and I will continue to order through BulkSupplements. Very pleased with their products and fast service :))*

Great powder
Works better than other l tyrosine products I have tried. I notice immediate results unlike other l tyrosine products where I notice nothing.*

On 5/10/2016 Airin said...

Great powder
I love bulk supplements! I have been shopping with them for over a year now. I take l tyrosine because i have two MTHFR geneic mutations which means i do not make enough neurotransmitters. Taking methylated folic acid helps to make more, bUT without the raw materials to make dopamine and norepinephrine it doesn't make much difference. This is where the l tyrosine comes in. It gives me raw materials to make what i need. I have taken other l tyrosine supplements bUT do not notice any difference, whereas with bulk supplements l tyrosine the purity and efficacy so wonderful I notice immediate results!*

On 5/10/2016 Airin said...

L-Tyrosine powder
My daughter has been on a hormonal balancing program and the L-Tyrosine her health care provider had her use originally was very difficult to mix into a liquid. It had to basically be mashed into something thicker like peanut butter. This L-Tyrosine powder is so much easier to use, as it is a finer powder and mixes better. Much appreciated.*

On 4/20/2016 Janean said...

Better mood, energy and mental focus! It works!*

On 2/23/2016 Rob R said...

L tyrosine
I ordered l tyrosine and I am definitely NOT disappointed. I am going to be reordering it soon. I use it with my preworkout shake and I get a very noticeable increases focus. This is one supplement I very much recommend for anyone looking for more focus and concentration.*

On 2/23/2016 John b said...

Great for focus
When using tyrosine for my workouts, I notice a much increased and deeper focus. Also I'm getting much better sleep with vivid dreams. All of this means my recovery will be even better. L-tyrosine is an odorless, tasteless powder that goes down easy.

On 1/31/2016 James said...

helps normalize neurotransmitters use labwork to determine need
this is a good clean tyrosine powder which i use to help normalize neurotransmitter levels when labs indicate they are off, recommended for this but best to do lab checks to make sure it's right for you. *

Good Quality and great for fitness and weight loss
I don't advise following my behavior but the following information may be very usefull for you. I usually take mega doses, in the range of 1 to 3 grams per day. Single dose in the morning. A full tablespoon. Never felt any side effects but it may be to my personal chemistry, No withdrawal symptoms either. However after a week or so, i started to lose appetite, and for me that was great. I had been fighting with overweight for several years, strong sedentarism and cravings for sugar. Never been able to sustain a diet due to hunger attacks. and I hate the gym. With L-tyrosine my resilient hunger become far more manageable and after 6 weeks I was able to have 2 meals per day. currently I weigh 160 pounds (from 220), Have been taking it for a year. If i don't want to lose weight anymore I just take a more conservative dose (500mg). After a month on a reduced dose the hunger attacks come back. It has been good for depression, apathy and procrastination. From a sedentary behavior I did become active and more motivated. I am diagnosticated with Bipolar type 2. but seldomly I have hypomanic behavior and it always has been manageable. 99% of the time is a chronic depression resistant to traditional medication. L-tyrosine has helped me a lot more than lithium or lamotrigine (which I still take). HOWEVER I STRONGLY WARN BIPOLAR 1 OR 2 WITH STRONG MANIC OR HYPOMANIC BEHAVIOR TO STAY OUT OF TYROSINE. The other thing is take it takes a while to start kicking in, and also to start kicking off. more than a month in both cases. I started taking it because i read "the way up from down" from PRISCILLA SLAGLE, MD*

I use tyrosine to aid in focus and muscle fatigue prior to strenuous exercise. I couldn't be happier with the qua and price and customer service from bulk supplements. *

Not Tired Thanks to Tyrosine
This is my second go with tyrosine from I had waited a month to reorder to see how I would respond to my workouts and I will say, in my case, there was a big difference.
I have been using tyrosine now for a week and my post workout blahs are gone! I would feel drained after working out lately but now I am not as worn out mentally and even physically. My workouts have only increased in intensity so I know that tyrosine is effective in my case. I stagger dosage and go high on back and leg days, like 2 grams, and use about a gram for other workouts.
Its worth a try to help ease the stress of heavy lifting and grueling workouts.*

On 9/30/2015 Tom said...

Highly Recommended
Bulk Supplements is the best when you need pure supplements. I've taken Tyrosine before from other manufacturers but this is definitely the best results I've gotten. Worth every penny.*

On 7/25/2015 John said...

It works
It mixes well with water, doesn’t have any distinctive odor, and is almost tasteless.
I have been taking it for more than a week already (although, after reading more about this amino acid, I increased the recommended dose up to 1 gram per serving – 3 times a day) and noticed that my choking feeling started to disappear. Sometimes I have a feeling as if I have an anxiety attack for no obvious reason, my breathing becomes shallow. Looks like L-Tyrosine helps to manage stress-like feeling.*

L-Tyrosine, is an anti-stressor for extreme cold, intense exercise, and a precursor for dopamine to improve cognitive alertness
I bought this l-tyrosine for help with ADHD. I have noticed that taking two grams before running a half-hour of Peak-8 sprints in the cold predawn morning that really I can just fly along. It was absolutely no problem to increase these exercises to seven days a week now, as well. (No willpower was required.)

The following benefits of l-tyrosine has been abstracted from MEDLINE (GreenMedInfo):

1. Deficiencies of the amino acids tryptophan and tyrosine may play a key role in autism.
2.The amino acid tyrosine is superior to synthetic T4/T3 combination in reducing TSH [Thyroid Stimulating Hormone] and improving mood in winter, whereas the T4/T3 combination worsens mood in the summer with no improvement in winter.
3. Tyrosine improves clinical signs of dopamine-dependent depression.
4. Tyrosine is an effective treatment for narcolepsy.
5. Tyrosine supplementation improves cognitive and psychomotor performance in cold conditions.
6. Tyrosine supplementation mitigates memory decrements during cold exposure.*
