Swanson Vitamins, L-Lysine, 500 mg, 100 Capsules

L-Lysine is an oral capsule supplement. The source panel lists L-Lysine 500 mg per 1 capsule. Lysine is an essential amino acid required for protein synthesis. It also participates in connective-tissue processes, including collagen cross-linking, and is a precursor in carnitine synthesis. Its essential-amino-acid identity means nutritional supplies contribute to the body's available protein-building substrates.

As a dietary supplement, take one capsule two to three times per day with water on an empty stomach.
