About Life Extension – N-Acetyl-L-Cysteine, 600mg – 60 caps

Life Extension N-Acetyl-L-Cysteine (NAC) delivers 600 mg of this well-researched amino acid derivative per vegetarian capsule. NAC is a bioavailable form of L-cysteine, a sulphur-containing amino acid that serves as a direct precursor to glutathione — one of the body’s most important endogenous antioxidants. Each bottle contains 60 capsules, providing up to a 60-day supply at the lowest recommended serving frequency.

This product is formulated with a clean, minimal ingredient list and is encapsulated in vegetable cellulose, making it suitable for vegetarians. Free from gluten and lactose, it is designed to fit a wide range of dietary lifestyles. Life Extension is known for its science-backed approach to supplement formulation, and this NAC product reflects that commitment to quality and purity.

Each capsule can be taken with or without food, offering flexibility for everyday use. As with all food supplements, this product is intended to complement a varied and balanced diet and a healthy lifestyle, and is not a substitute for a diverse nutritional intake.
