NOW Foods L-Ornithine Powder 8 oz

NOW® L-Ornithine Powder supplies pure, free-form L-ornithine with no fillers. Ornithine is a non-essential amino acid that plays a central role in the urea cycle — the body's system for converting the ammonia produced by protein metabolism into urea for elimination. Because it works alongside arginine in this cycle and helps clear the byproducts of protein breakdown, ornithine supports healthy protein metabolism and the body's natural recovery processes. The adjustable powder is popular among athletes, often taken on an empty stomach or before bed.*
