21st Century, L-Lysine, 1,000 mg, 90 Tablets

21st Century, L-Lysine, 1,000 mg, 90 Tablets provides L-lysine, an essential amino acid that must be obtained from the diet because humans cannot synthesize it. Lysine is incorporated into body proteins and contributes to normal tissue protein synthesis, enzyme and hormone production, and collagen-related structural proteins. Dietary sources include meat, dairy, eggs, legumes, and other protein-rich foods.

This exact variant is labeled with 1,000 mg, a labeled serving of 1 Tablet, 90 servings per container. Supplemental lysine can provide a measured amount when dietary intake is limited, but it should be interpreted as an amino-acid supplement rather than as a treatment for infection or other disease.

Adults take 1 tablet daily with a meal, or as directed by a healthcare provider. Do not exceed the recommended dosage.

Consult a healthcare provider before use if pregnant or nursing, taking medications, managing a medical condition, or planning a medical procedure. Stop use if an adverse reaction occurs. Keep out of reach of children. Do not use if the safety seal is broken; store as directed on the label.
