Arginine & Ornithine 500/250 mg Capsules

NOW Foods Arginine & Ornithine 500/250 mg Capsules deliver a powerful combination of two closely related amino acids in free-form and highly bioavailable formats. L-Arginine is a conditionally essential amino acid that serves as a key precursor to nitric oxide, supporting healthy circulation and normal vascular function. L-Ornithine works synergistically alongside L-Arginine and plays an important role in the urea cycle, contributing to normal nitrogen metabolism in the body.

Each serving of two vegetarian capsules provides 1,000 mg of L-Arginine and 500 mg of L-Ornithine, offering a convenient and precisely dosed combination in a single daily serving. These amino acids are particularly popular among individuals seeking to support their active lifestyle, pre-workout nutrition, and overnight recovery. The free-form amino acid format ensures rapid absorption without the need for prior digestion.

Formulated by NOW Foods — a trusted leader in evidence-based nutrition since 1968 — this product is manufactured in a certified GMP facility and is free from common allergens. The vegetarian capsule shell made from hypromellose makes it suitable for vegan and vegetarian lifestyles, while the clean, minimal formula avoids unnecessary fillers or artificial additives.
