Overview

NOW Foods Sports Arginine & Citrulline Powder is a dietary supplement built around a 1:1 blend of the amino acids arginine and citrulline. The formula is positioned to support protein metabolism and utilization, along with the maintenance of muscle tissue. Because these amino acids also act as intermediates in the urea cycle, the product is designed to fit into the body’s natural process for handling ammonia and converting it to urea.

This powder is suitable for adults looking for an amino acid supplement in a simple, unflavored format with no other ingredients added. It is also presented as keto friendly, vegan, kosher, halal, non GMO, steroid free, and GMP quality assured. The product is additionally listed under the Informed Sport program, reflecting testing standards associated with that certification.

As a powdered supplement, it is intended to be mixed with liquid and taken twice daily. The source also notes that any arginine not converted to urea may circulate through the body and be used for other functions, including protein synthesis.
