Life Extension Arginine Ornithine Powder, 5.29 oz (150 g)

Life Extension's Arginine Ornithine Powder is a dietary supplement formulated to support muscle health and recovery after exercise, combining two amino acids in a powder form. It provides L-arginine hydrochloride and L-ornithine hydrochloride, with the manufacturer noting that these ingredients have been studied for their roles in promoting muscle mass, strength, and healthy body composition in exercising adults, as referenced in clinical research. The product is designed to be taken on an empty stomach, with one level teaspoon offering a specific ratio of these amino acids.

This powder is unsweetened and contains no other ingredients, aligning with a minimalist formulation approach. Life Extension highlights its commitment to science-backed supplements, with over 40 years of research into formulations. The product is certified gluten-free and non-GMO, which are common but relevant certifications for this category. It comes in a 150-gram container providing approximately 48 servings, and it is also available in other forms like capsules from the same brand, though this variant is a powder only.
