L-arginine HCL attaches the amino acid to hydrogen chloride (HCL). HCL has a neutral pH, which in turn neutralizes the otherwise bitter taste of L-arginine when in powder form.

Our take: An affordable L-arginine supplement that comes in convenient capsules. What we like: Contains both HCL and AAKG forms, with a total of 800 mg of L-arginine.

Freeform L-arginine is most similar to the amino acid that is found naturally in foods. L-arginine HCL is easier to digest and does not taste bitter because it combines with hydrogen chloride.

To add to our experience employing a standard infusion of arginine hydrochloride, we have examined the dose–response curves of human growth hormone and insulin concentration in plasma after 1/12 ...
