This supplement contains no fillers of any kind. There are no extraneous chemical groups attached; it is made up of nothing but pure base L-Arginine. This product is not considered vegan.


As long as suggested serving sizes are adhered to, no adverse side effects should be experienced. However, taking too much Arginine may cause minor side effects such as upset stomach due to an accumulation of extra stomach acid. Arginine may also have the effect of altering levels of potassium, which can be particularly dangerous for those with liver issues. Those who are taking ACE inhibitors or diuretics and have kidney problems should not use Arginine unless required to do so by a doctor. Women who are pregnant or nursing should not take this supplement. Those who have recently had a heart attack or are taking performance enhancement or blood pressure medications should not take Arginine either.


This supplement is easily dissolved in water at higher temperatures. This supplement has been found to have a somewhat bitter taste. For this reason, it is best to mix it with a sweet citrus drink. Lemonade is probably the best drink for this situation, though some might suggest ditching the drink and taking Arginine capsules instead.

Great Product...great service
This product is solid. I felt results almost immediately. Having circulatory issues during workout is something I have struggled with for a while.

Great Pump

On 10/4/2016 Dominick said...

It's Working as hoped
I purchase L-Arginine Powder Base) along with L-Citruline for the combined effect of increasing Nitrus Ozide to relax and open blood vessels for a better "pump" while working out and hopefully to bring my blood pressure down a few points. The first workout using 1 teaspoon each about :30 prior to working out gave me the great "pumped" feeling that lets you know something good is happening. I don't have a blood pressure sensor, but I believe my blood pressure is lower using 1t each upon waking and before bed as I can no longer feel slight pulsing in my hands at bedtime. I take them mixed in a glass of water and don't find the taste objectionable. I was surprised when I received the package almost immediately by Priority Mail. Very, very happy with the product and Bulk Supplements.*

On 9/20/2016 Barry said...

Amazing and a great addition

Best on the Market
It best to mix this with Lemon Juice with no sugar added . But its the best kind i ever tried on the internet by far.*

On 3/9/2016 Jerry said...

Good quality L-Arginine
I recommend this product for anyone looking to purchase an L-Arginine powder. I have been taking L-Arginine on and off for a couple of years. This is good quality. I take 5 grams before breakfast and 5 grams before bed. I will add a 3g dose before workouts too. This dosage is much higher than suggested by manufacturer, but I can tolerate it and it has significant effects on my energy and blood flow.

My only complaint is that the packaging it comes in doesn't seal properly after opening. I have to double bag it in a ziploc to keep it fresh. *

On 3/8/2016 Bradley said...

What I was missing
I decided to add L-arginine to my pre-workout mix after talking with others. I noticed a difference in my workouts immediately. Blood flow into my muscles was defiantly more noticeable. L-arginine will now be a staple in my pre-workout from now on!*

On 2/3/2016 Brett said...

This is the real deal, with the great pumps, and longer lasting exercise I see no reason not to buy again.*

L-Arginine Capsules.
This product is one of the most important amino acids that as a bodybuilder/athlete needs to incorporated in their diets. The benefits that I obtain are the synthesis of nitric acid to decrease my recovery time and improved my energy. I take along L-Citruline as they work together. As a dietary supplement it improves immune and hormone, and kidney support.*

L-Arginine is Great!
I began taking L-Arginine a few months ago and I wasn't getting the results that I thought I should. I tried it from another source to start with and I did not get the results that I was hoping to get. I had been in too much of a hurry to read the label of the product I purchased from a local store until I had been taking it for a couple of weeks. It had fillers in it to stabilize it or something like that. It did not work.

I then ordered the powder form from Bulk Supplements. Within two or three days I noticed a difference. I was after a reduction in my blood pressure and it helped immensely. I have neuropathy in both arms and legs and I could feel a throbbing pain, especially in my hands. For the most part that pain has subsided to a tolerable level, except when I miss taking it during the day.

I am impressed with the quality of the product from Bulk Supplements, it is second to none. If you haven't ordered from them you will also find that their customer service is great as well.

Maximum blood flow everywhere!
Let me just start by saying, that I've been buying arginine in mostly capsule form, for around fifteen years. I ran out of capsules and I decided to buy some powder in bulk, and maybe cap them myself. But I never got around to it, and just drank a teaspoon or two in cold water... And HOLY S***!!!! Ten minutes after I drank this, I was fooling around with my girlfriend, and I had the fullest hardest erection of my life! I stood up, and pulled my shorts down, and her eyes almost popped out of her head! That was the best look a girl has ever made towards my junk! I'm a 5' 6" white guy, so let's just say that was the only "look" a girl has ever made at my junk. Lol... I will definitely be continuing to buy this product. As well as L-Citrulline. The two combined make me feel unstoppable in the bedroom. Oh yeah, and good pumps at the gym too ;)*

L-Arginine Base
Just reordered L-Arginine Base, no one ever says how much they take, but I weigh 210 and take 1 teaspoon Arginine-Base plus 1/4 teaspoon Bulk Supplements Pine Bark Extract, 5 times a day. This works for lowering my blood pressure into very acceptable range. It is also supposed to raise your Nitric Oxide levels. Research this combination online to see if it's right for you.*

Excellent - does what it supposed to do
Take on off workout days to get a dump in hGH levels. I add it ribose and whey to get the most benefit.*

Reduced Hyper-T with L-Arginine
I am just finishing up the first order of L-Arginine from Bulk Supplements. I love it because it has helped with some of the symptoms that I have with neuropathy. It is not a cure but it helps along with the other amino acids that I am taking to ease much of the discomfort that I have had with this condition. The sad part of this is that I am not diabetic but have the symptoms just the same.

I began taking L-Arginine a few months ago along with ALCAR. The ALCAR helped a great deal but I still had throbbing pain that seemed to be coincident with my pulse. The L-Arginine opened up the blood vessels to the point that generally, I do not have the throbbing pain as before.

I checked all of this out with my doctor and she gave me the go ahead and she has been amazed at the results that I have had. I got off one prescription medicine that is supposed to help with neuropathy and I have cut the second down to taking it at bedtime to help me sleep longer at night.

This may or may not help you with similar problems but I am more than satisfied with the products that I have gotten from Bulk and the speedy service. The product was shipped the same day as the order. Thank you Bulk Supplements!*

L arginine
I've been ordering my arginine from other sites in the past. I ordered from Bulk Supplements this time and was not disappointed. It came very quickly, was very affordable and the packaging is unique. The arginine powder mixed well with my water and pink lemonade mix. I will continue to use Bulk Supplements in the future.*

Amazon order: 108-6178994-7357034
I ordered this from, I paid a bit more but I came pretty fast and the product was packaged very good, The mail man left it on the step out front and got a bit wet but it seem to be OK. The products mixes well in lemon aid and covers the biter ness very well, I also use lemon aid for the Longjack product, I am very pleased with both products.*

We've been purchasing L-Arginine in pill form for quite some time. Very glad to discover Bulk Supplements with their pure supplements.

This is the way I like to shop: buy in bulk and save tons on packaging but getting quality products.*

On 10/16/2014 Janet said...

many uses
yes, it helps you when you are exercising, but when you have low testosterone it helps in other ways as well. i have normal blood pressure, so all those expensive prescription pills with the warnings to call your doctor if you have a problem after 4 hours caused me to nearly pass out from low blood pressure. not this stuff! works every time like a charm! one teaspoon 30 minutes or so before and you will never buy another little blue pill! i mix it in a shot glass with water and gulp it - tastes terrible but is SO worth it!*

Get the PUMP/Contributes to Power
Product mixes great, gives great pumps, fast shipping from the company always order from bulksupplements.

L-arginine helps your body manufacture creatine, a protein that contributes to muscle mass and power. L-arginine also helps the body get rid of creatinine, the waste product associated with this process [source: Mayo Clinic]. For these reasons, the bodybuilding industry loves to tout creatine and L-arginine supplements.

L-arginine is a vasodilator -- that is, it dilates the blood vessels, allowing more blood to pass through at once.

Gains at the gym
When I started taking L-Arginine I was at a plateau with my workouts. I was stuck at 250 lbs. on bench and 275 lbs. with squats. One week after taking 5000 mg. of L-arginine a day my bench went up to 275 and my squats went up to 300. Now I look forward to hitting the gym more, now that I've climbed out of my rut. *

Absolute best way to buy L-Arginine
I have been buying L-Arginine in bulk from www.bulksupplements for several months. I take 5g doses twice a day, and mix L-Citrulline in a 1-to-5 ratio. This was a recommended dosage for the "renewal" benefits for someone my age (66). It is the least expensive way to a regular maintenance routine, and I always find consistency and excellence in my orders.*

On 6/17/2014 Gary said...

The product is pure, mixes well, and as always, was delivered quickly. I mix this with BulkSupplements BCAA powder and Glutamine powder in juice, and although it does give an odd flavor (not bad, just strange) and changes the color of the juice, it's an effective product. Excellent to stack with any pre-workout supplements. *
