Now L-Citrulline (100% Pure Powder) 4 oz

L-Citrulline (100% Pure Powder) Overview

The amino acid L-citrulline has a few different roles to play in metabolism, but by far most supplemental L-citrulline users are thinking in terms of enhanced nitric oxide (NO) production. NO promotes lower blood pressure, better circulation, erectile function and much fuller muscular pumps when working out. As a prescursor to arginine, and therefore NO, NOW L-citrulline can be used alongside arginine or in place of it to enhance nitric oxide production for any of these purposes. Adding NOW L-Citrulline 100% Pure Powder to your preworkout drink is a great way to give it a nitric oxide boost. You could use arginine powder for one of these purposes, too, but as anyone who has done so will tell you, the taste of arginine is extremely bitter and unpalatable, almost unusable. L-citrulline doesn't exactly taste good, but it blends into shakes and other drinks much better, supporting NO production far less expensively than hyped out NO formulas.

L-Citrulline (100% Pure Powder) Description from Now
Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with Arginine and Ornithine to rid the body of ammonia, a byproduct of protein metabolism. Because Citrulline is a precursor of Arginine, it provides a readily available source material for Arginine production, which in turn, can be used for the production of Nitric Oxide (NO). NO plays a fundamental role in vascular function and blood flow. Citrulline therefore, not only supports detoxification pathways, but also supports NO production and a healthy cardiovascular system.
