L-Citrulline Powder

Key Features

  • Promotes good blood flow
  • Useful for intense physical activity
  • A precursor to Arginine
  • Taste

  • Mixability

Citrulline has been used by several athletes to increase performance and recovery time by limiting the amount of ammonia accumulated in the body and by preventing the buildup of lactic acid. The nitric oxide produced by Citrulline is useful in helping to produce Creatine, a compound closely related to the development and maintenance of muscle. This supplement is particularly useful for those involved in endurance exercises or any sort of intense physical activity.

This product is Kosher certified.


Serving Size & Timing

This supplement should be taken in servings of 3000mg to be consumed two times per day, one hour to 45 minutes before a workout. When taken along with Histidine and Beta Alanine, these three supplements can go on to create Carnosine, which further improves the effectiveness of production of Nitric Oxide. Those who are taking any amino acid as a supplement should also be aware that it is necessary to supplement other amino acids in order to maintain a necessary balance.

L-Citrulline - 100g Pure Powder
I have competed in endurance sports for more than 35 years and was not sure what to expect with the use of this product(L-Citrulline - Pure Powder). It dissolved easily and had no noticeable taste. I definitely noticed an increase in stamina during my workouts. I will continue to use this product and would recommend others to get this from Bulk Supplements.*

On 11/21/2015 Richard said...

good quality
seems to be different consistency powder (more sugar like) than another bulk website I order from in which the powder is more of a flour like consistency but seems to mix better with less clumping and is of the same quality plus cheaper*

On 11/16/2015 Branden said...

Dissolves easily, tastes slightly icky
I take l-citrulline before bed and it dissolves really easily in water. It does have a slight odd taste to it. Kinda like soap or something. So far I have slight positive effects after about a week.*

l citrulline
Best product i have ever tried. After 3 days i was able to run further and had a ton more energy.*

Great stuff*

On 10/20/2015 cr beaumont said...

Dissolves well & there is no taste!
This product is easily dissolvable in any liquid & the taste is undetectable. We are taking this l-citrulline to boost the nitric oxide level in our bodies.*

On 10/20/2015 Richard said...

Disolves well
This supplement was recommended to combine with L-Arginine 5000...Will know full review after 30 days. So far so good, easy to use and dissolves well.*

On 10/13/2015 Maureen said...

Good price, good product. I dissolve 1 tsp into a glass of water and drink. Slight salt taste but can easily be covered with a little lemon or similar juice. Only had about a week but seems to help so far.*

On 9/25/2015 Joe said...

Pump you up!
Surprised at how quickly you start to see results. The first day or two, I felt flush after performing pushups but that is no longer the case. Right after a work out, you feel incredibly pumped. I dare you to wear compression a compression shirt and not feel like you're going to bust out of it. The powder dissolves almost completely in a standard shake cup using either water or a water/cocoanut water mix. You need to give this a shot. *

On 9/23/2015 Mike said...

I buy l-citrulline in 1kg amounts now. Has a pleasant taste and no side issues that I am aware of. Keeps me sexually active. At 70 I need all the help I can get Shipments are on time and in good shape. *

On 9/19/2015 Ron said...

I have been taking citulline far two weeks now
I have been getting massive pumps now !
I 58 years old and the pump is back !*

On 9/13/2015 mark said...

Mind blowing pumps
I wanted this product because research indicated that it expands your blood vessels, allowing for more nutrients and oxygen to pass through. It is a precursor to l arginine and in fact works better than l arginine because of the way arginine is broken down by your system. Let me just say, IT WORKS!!! It almost works too well. The pumps I've experienced while taking this pre workout are beyond imagination. On bicep day, my arms will get so swollen, that they actually hurt. They feel as though they may EXPLODE! It also helps me to get more reps into my sets, because of its ability to widen blood vessels and clear out more lactic acid and by products of heavy exercise. Great product, great price. Almost tasteless powder. has done it again!!! Definitely will be ordering more of this product, as well as many others!*

On 9/7/2015 Brendan said...

Product received rapidly and correct amount etc. *

On 9/2/2015 Ron said...

Dissolves well & there is no taste!
I am excited to see results on my blood pressure. Great price & glad to be able to buy in powder form. This company is awesome! Great products, great prices, & fast delivery!*

On 9/2/2015 Richard said...

Great Products
I have only been using this for one week, and can already tell the increase in endurance and less fatigue. Products arrived quicker than expected. First time ordering from this company. I will be a return customer.*

On 8/25/2015 Michael said...

L citrulline
Great shipping. Great product. Pumps in the gym are unreal while using this powder. This is my third time ordering it and will continue to do so.*

On 8/3/2015 Ronald said...

Best quality l-citrulline I've found and the best customer service here*

High blood and Erections
Blood pressure has lowered with this product. Dr. has cut my pill intake for high blood to just 1 tablet a day from the former 2 a day. Erections harder and more often in the morning.*

L-Citrulline Powder
It's too soon to tell if it's making a difference for me yet or not, but I have had so much success with Bulk in general. Products are always shipped quickly and I enjoy using their products which tend to be more reasonable than other companies similar products. *

On 7/15/2015 Robert said...

I can't believe how inexpensive this bulk powder is compared to capsules! Bought a 1 kilo bag and should last for months. I combine it with 1/16 teaspoon of grape seed extract powder in a warm glass of water twice a day, and while I think it helps with my exercise, I'm positive it helps in the bedroom!! I haven't had a chance to see if it lowers my blood pressure yet, but I'm quite optimistic.*

On 7/12/2015 Michael said...

Superior to citrulline malate
This is better to take than the malate version or straight arginine as this bypasses the liver and goes straight to the system without any wasted. You need to take 2X the amount of citrulline malate to get the same result*

On 7/8/2015 Robert said...

i have ordered citrulline from Bulk Suppliments twice . It is always delivered on time and has good quality. It does lower blood pressure somewhat but really does help in my sexual performance. *

On 6/8/2015 Ron said...

Product Arrived on Time and looks good
I have not been taking this for very long. I can say that the product arrived on time, intact and appears to be as depicted in the online store. If this product works as well as L-Arginine then I will be in good shape. I look forward to the results.*

L-Citrulline for Lower Blood Pressure
Switched to powder with Bulk Supplements after purchasing capsules from another supplier. The powder mixes easily with warm water and I drink it straight for lowering blood pressure taking 4 teaspoons spread throughout the day, this is more that recommended but works well for me. L-Citrulline is mentioned in Dr. Ignarro's book NO More Heart Disease and I will continue to buy in the 1 Kilo amount.*

On 5/26/2015 David said...

Don't need Big Pharma anymore
1 gm of L-Citrulline from Bulk Supplement along with 4 gms. L-Arginine, Red Beet Root and Fenugreek and I wake up with woody just like in the old days. This stuff works better than prescription drugs and is safer with no side effects. Highly recommended.*

On 5/25/2015 David said...

Game changer.
Bought 1kg of l-citrulline after trying the free 100g sample for a week. This stuff works. Simple as that. Bloodflow has improved drastically, erertions are the same as when I was 16 (I'm 30 now) and the pumps after workouts are insane. Definitely recommend l-citrulline to your friends for health and quality of life improvements.*

L- Citrulline
THIS product Is fantastic ! I have always looked for a product where I could Naturally lower my blood pressure I learned that the green inside of a watermelon worked.. So I ordered the supplement from your company which was L- Citrulline 500 mg .The doctors had a rough time getting my blood pressure down for over two years. They had me on three BP medications I have been taking one teaspoon of this product for 3 days and NO BP medication and my Bp has not risen over 139/80 since ! Thank you for a wonderful product . There is no taste mixes well with any I ordered more for my sister whom does not take medicine due to her religion .*

On 5/6/2015 JW Bill said...

Since using this product along with L-arginine while working out I've noticed a huge difference in my body, especially in my core. My abdomen looks great. I love the powder more than the pill also. *

On 5/6/2015 Antoin said...

I love having access to a product in its cleanest form. I just add this to my preworkout NO drink along with the creatine and arginine I get from The amount of money and hassle I save with Bulksupplements is fantastic. I'm saving hundreds of dollars a year!*

On 4/27/2015 Scott said...

L-citrulline powder
Great product. Easy to take. Feeling better already. Fast shipping. *

On 4/25/2015 Kenneth said...

All around great amino acid.
Chose citrulline for it's health and performance benefits. L-citrulline increases serum l-arginine more than supplemental arginine itself. It also has a similar effect with l-ornithine.

After just a single 3g dose I was able to improve my blood-pressure by a few points and have a greater pump in the gym. I'll definitely be ordering l-citrulline in the future.

Go here to learn more:*

On 4/23/2015 James said...

Great Product.
Use this as an ingredient in my pre workout and it definitely works well. The taste is good as well as the performance. Will buy again!*

On 4/14/2015 MICHAEL said...

Outstanding Product!
Very happy with this product, very clean, easy to consume and much more affordable than the Now 1g capsules I was taking. Upped dose from 2g per day to 5g per day once receiving this product. I can really feel the difference.*

On 4/14/2015 JB said...

Great workouts
L- Citrulline is so much better than CM. This gives you great workout and not just a good pump but noticeable endurance as well. *

On 4/13/2015 Anthony said...

Works great in my pre/intra-workout drink
After receiving and using L-Citrulline for 8-10 days, I was impressed enough to order again directly from I'm taking the recommended serving size in the morning and evening before my work out and feel a noticeable difference in my workouts. I'll definitely continue using this product for my pre/intra-workout drink. *

On 4/10/2015 J. E. said...

Awesome product!
I will be buying this product again! It didn't have that bad of a taste like most amino acids do and it gave me a really good pump when i used it! I also have very little muscle fatigue when i use this product!*

On 4/8/2015 Casey said...

Helps get the job done
I had run out of my last order of citrulline and noticed it the following few days. My routine usually lasts an hour to 75 minutes and it helps to supplement with citrulline as well as betaine and beta alinine. On my third day with out it, it was a longer than usual workout and I felt gassed for sure.
This stuff does work well and for those who work out alot for an hour or so a day, I think you will benefit from this as well.

On 3/24/2015 Tom said...

nice pump!
This stuff works great! It gives you a nice pump in the arms especially. Seems to be pretty pure, and it tastes fine. I would difinetely recommend it. Bulk supplements seems to be the best company for me so far.*

On 3/12/2015 travis said...

l- citrulline

L-Citrulline is Awsome
I heard of this product for blood flow and it works pretty well. I like it a lot.*

On 2/24/2015 Alvaro said...

great pump!!
This is a great alternative to l-arginine because its easier on your stomach and you get a great pump at the gym. Buying it from bulk supplements is the best for prise and super fast shipping. I love this site...*

On 12/17/2014 Adrian said...

Great for vascularity, must add to pre-workout!
I have been adding this to my pre-workout shakes, with great results. My shake consists of beta-alanine/creatine/L-Carnitine followed by a taurine pill. Works great in getting the blood pumping for my late night workouts. This product is clean, sugarless and tasteless and I have yet to find it anywhere for a lower price. *

On 12/5/2014 Michael said...

I found the l-citrulline to be superior the the l-citrulline malate. There seems to be no difference in the absorption. I had more energy and a better pump. Also, I did not get the heartburn that I sometimes get with the l-citrulline malate.*

On 9/15/2014 ERV said...

L-Citrulline is the main hero
L-Citrulline alone works better for me than L-Citrulline with DL-Malate 2:1. Next, I'll be trying the L-Citrulline with Histidine and then, later, with Beta Alanine to see what those two extras will produce. I have to really start working on my ED, and this is the way to begin.*

On 9/11/2014 Stanley said...

Good Pump
I was taking L-Arginine for awhile due to a doctor's recommendation for something other than my heart. The Arginine was from here was well, but was ordered through Amazon. I decided to come through here since they have free shipping and much, much more information on the products and I can choose the size.

The shipping was fast overall. The Citrulline actually is more potent than Arginine, so you get more of an effect. I take 3g-4g in orange juice as my preworkout around 30-45 minutes prior and I can tell that I am more vascular since I can see my veins showing after only my warm-up sets. It also increases my stamina and energy, so I can keep going.

My only complaint is that it is very tart. It isn't very terrible, but it'll give some people a surprise. I usually just mix it with a spoon in the glass of orange juice and it mixes pretty well (A bit left at the bottom, but not much) and then chug it.

I definitely recommend not only this product, but this company! I got a 500g bag and it'll last me for quite some time!*

On 8/27/2014 Andrew said...

great stuff
This works with 1 teaspoon Beet root powder, 1 teaspoon grape seed extract and 1 teaspoon citruline mixed in pure water twice a day and if you have ED this should change that!*

On 8/6/2014 Ron said...

Good Stuff and BulkSupplements price is the best.
Citrulline is an amino acid that our bodies convert to another amino acid called arginine, which is then converted to nitric oxide, a compound which relaxes blood vessels and stimulates blood flow to muscles and other pats of the male anatomy. (research it) It is also thought to reduce buildup of Lactic acid in muscles and thus reduce soreness and recovery time between workouts. In my opinion this effect is legit. It isn't hugely dramatic, but it does work. Like all products that I've tried, this stuff is high quality and the cheapest I've found anywhere. Also, their customer service is great and shipping is crazy fast. As long as they keep doing business this way, I see no reason to buy from anywhere else.*

On 7/24/2014 John Goold said...

Good product pre-workout
Just started using L-citrulline as one of my pre-workout ingredients! Absolutely love it! The taste isn't the best but it definitely aids in giving me an energy boost and making my muscles feel looser and not sore! It helps get rid of the excess ammonia in your body which contributes to muscle soreness. Highly recommend this product or citrulline/malate for those needing a pre-workout boost,*

On 7/19/2014 Andrew said...

L-Citrulline Powder 100G
I would certainly buy this again. Packaging was great; delivery time was acceptable.
The main think I like about L-Citrulline powder is that it helps with my recovery time after workout. It is most noticeable after leg day. Before I started using L-Citrulline I was tremendously sore; since I've been using this the soreness factor has been cut in half (at least). Great buy.*

On 6/22/2014 Dan said...

Extra reps
I tried just a small dose 3mg + some malic acid I had on hand and noticed a pretty good response right away during my AM workout. I was distracted by something and realized I had doubled my reps for a given move w/o even thinking about it. So I think this stuff is pretty good. *
