This precursor to glutathione synthesis depletes at a high rate and may be related to premature skin aging. It is recognized as a potent, antioxidant amino acid. L‑Cysteine can be obtained from dietary protein or synthesized from the amino acid ʟ‑methionine. Its depletion may be partially related to the faster aging of skin, especially with smokers. ʟ‑Cysteine can act as an antioxidant. L‑Cysteine is a sulfur-containing amino acid which, together with glycine and glutamic acid, forms the all-important antioxidant glutathione. ʟ‑Cysteine also contributes to protein formation in the form of beta‑keratin, which is a major component of skin, hair, and nails. Targeted supplementation with ʟ‑cysteine could prove to be indispensable to your ongoing health and vitality.
