Arginine and Citrulline are two amino acids that are integral to protein metabolism and utilization, as well as to the maintenance of muscle tissue.* Both are key intermediates in the urea cycle, where they participate in the detoxification of ammonia via the production of urea.* In addition, any arginine not converted to urea enters general circulation where it is distributed to various tissues and metabolized for other uses such as protein synthesis.*

Natural color variation may occur in this product.

Not as potent in comparison.

I'm a regular buyer of "Now" Products however, in all honesty, after taking the brand "Nature's Bounty" L-Arginine until I was able to order from Amazon of which then stopping Nature's Bounty and taking (3,000 mg) of the "Now" product L-Arginine everyday for 3 weeks and then, the next morning just taking (1,000 mg) of the "Nature's Bounty" L-Arginine, I can honestly say that I felt more of a potency kick after taking only (1) tablet (1,000 mg) L-Arginine by "Nature's Bounty". In a nutshell, I felt more of a potency kick a few hours later after taking (1) tablet of Nature's Bounty (1,000 mg) more then I did taking the "Now" brand of (3,000 mg) everyday for a week.

My Cardiologist recommended to help with Raynaud's.

K-Arginine with a medication was recommended for my heart issue, that also improves symptoms of the autoimmune disease of - Raynaud's. It works for me.

A great alternative to more marketed stuff

Look up some specific side effects relating to blood related effects and triggering symptoms of Herpes, and that's all you have to worry about with these. Otherwise, they work.
