Solgar, L-Cysteine, 500 mg, 90 Vegetable Capsules

L-Cysteine is an oral capsule preparation. The documented 1 Vegetable Capsule serving provides L-Cysteine 500 mg. L-cysteine is a sulphur-containing amino acid involved in protein synthesis and the formation of glutathione. Its thiol group contributes to the structural and chemical properties of many proteins. This preparation supplies the documented free amino acid as a nutritional substrate. Its amount describes cysteine itself, preserving the distinction from N-acetylcysteine, a related derivative with a separate molecular identity and formulation context.
