Product description Dietary supplement containing L-Arginine and L-Ornithine. Properties: Arginine & Ornithine combines two complementary amino acids in one convenient supplement. Arginine is essential for the proper elimination of urea from the body, which occurs through a critical metabolic cycle that detoxifies the body of nitrogenous compounds, which are normal byproducts of protein metabolism. Ornithine is synthesized from arginine and is a precursor to citrulline, proline, and glutamic acid. Both of these amino acids are popular among athletes and other active individuals. Natural color variations may occur in this product. Recommended intake: Take 2 capsules daily as needed, preferably with juice or water on an empty stomach, before exercise or at bedtime. Composition : L-Arginine (free form) 1g, L-Ornithine (from L-Ornithine HCl) 500mg, Hypromellose (cellulose capsule), Calcium Citrate and Stearic Acid (vegetable source).
