Now Foods Sports Arginine & Ornithine 500/250

Overview

NOW Foods Sports Arginine & Ornithine 500/250 is a dietary supplement that combines two amino acids, arginine and ornithine, in capsule form. Each serving provides 500 mg of arginine and 250 mg of ornithine, a pairing designed to support protein metabolism and nitric oxide production while also helping with the body’s normal urea elimination process.

The formula is positioned for athletes and other physically active adults who want amino acid support in a simple daily supplement. Arginine plays a role in the metabolic cycle involved in clearing nitrogen-containing by-products of protein metabolism, while ornithine is derived from arginine and serves as a precursor to citrulline, proline, and glutamic acid.

This product is also described as steroid tested and carries multiple dietary designations, including vegan, kosher, halal, non-GMO, and GMP quality assured. It is further identified as Informed Sport tested, meaning the brand states the product has been tested for trust in sport-oriented use.
