L-Lysine 500mg delivers an essential amino acid your body requires but cannot produce on its own. This fundamental building block supports protein synthesis and contributes to your body's natural immune response.
Why It Works
ESSENTIAL AMINO ACID: Unlike non-essential amino acids, lysine must come from external sources — your body simply cannot make it.
PROTEIN SYNTHESIS: Works as a key component in building and maintaining proteins throughout your body's tissues.
IMMUNE CONTRIBUTION: Supports your natural immune system as part of proper protein function and cellular health.
What's Inside

Why we carry it: NOW's rigorous quality standards and decades of amino acid expertise make this a reliable choice for essential lysine supplementation.
