Customer Ratings & Reviews

Rated 4.6 out of 5 by 16 reviewers.
Rated 4 out of 5 by Seems good! I believe it is working for me to increase my nitric oxide production. Haven't stopped taking it find out differently! September 7, 2016
Rated 5 out of 5 by Great Value Great value, very effective, potent! June 29, 2016
Rated 5 out of 5 by Big dose, decent size cap Some of these horse pills, I just cannot swallow. They go down just so far and then stick. This is a fairly good sized amount of arginine, a cap that goes down easier than a pill and the capsule is not big enough to create swallowing difficulties. As for its many benefits, researched here and elsewhere, I can say that I am pleased. May 11, 2016
Rated 5 out of 5 by Energy Combined w/other supplements, this aides passion revitalization. March 28, 2016
Rated 5 out of 5 by great We had been using this product for years and we're very satisfied with it. January 3, 2016
Rated 5 out of 5 by Some things work "hand in hand" My use of this is in conjunction with other supplements to help with blood circulation. September 10, 2015
Rated 5 out of 5 by LOTS OF VALUE WITH THIS L-ARGININE This is an excellent product in a very good potency, and at an outstanding price. Since I take 4 or 5 of these capsules at a time (along with the same number of 500 mg. L-Ornithine capsules), I really appreciate the low price which makes it easy and practical to buy several bottles at a time so I don't run out. You can read tons of material everywhere about all the values of L-Arginine. I've taken it since the 1960s or 70s. Works for me. September 9, 2015
Rated 5 out of 5 by exalant value I always have a extra bottle on hand so I won't ever run out... April 20, 2015
Rated 5 out of 5 by Great product If you are looking for a way to boost your stamina, this is the pproduct for you. It works and no downsides to the way it works. April 13, 2015
Rated 4 out of 5 by a good product I like this product . I think this is very effective when taken with a low carb low sodium diet for me. April 8, 2015
Rated 3 out of 5 by Close but not there The Arginine needs to be taken out of the capsule and, along with citriline malate and taurine, etc taken one swallow at a time for the mouth bacteria to mingle with it in order to make the arginine most effective. Lozenges are the very best for this application. March 22, 2015
Rated 5 out of 5 by Want to increase Nitric Oxide? If you want to increase Nitric Oxide, here is the product to do it. In order to have a measurable effect, you've got to take quite a lot of L-Arginine and I've found this to be the best value. February 22, 2015
