## Description

l-Arginine is most well-known for its use in cardiovascular support. Its other critical functions include assisting in wound healing, helping remove excess toxic ammonia from the body, supporting immune function, and promoting the secretion of several hormones, including glucagons, insulin, and growth hormone. It plays an important role in muscle metabolism by working to transport, store and excrete nitrogen. Suggested use is 1 tablet 1 to 3 times daily between meals. Please contact our in-houe customer support if you have any questions.

Review: Great supplement, very safe and good quality - I am using this as one of the supplements to help me with H. pylori. It seems to be working, obviously, in combination with other things. The good thing is that those body-conscious types who are always looking for latest and greatest supplement which will help them build that six-pack have already been taking L-Arginine in megadoses for years (in neighborhood of 35000/day!), and with no side-effects (except for scary muscles). So , based on that, I have been taking, on and off, about 9000mg a day, with no side-effects, only good results. In addition, should you have a problem with ED, this may just do the trick; keep in mind, you'd need to take a lot of it, see above. As with any supplement, start slowly and build up the dosage over time, and never stop abruptly either!
Review: I like L-Arginine - There's a lot of talk lately about NOS based benefits to men. I have found for myself that adjusting the amount taken and the rate of frequency taking it does change the results. Yet not everything happens as fast as microwave food. This path is a slow and gentle restoration to health. Allow it the time it needs to bring you back to center.
