L-Lysine 500mg

L-Lysine 500mg by NOW – Essential Amino Acid for Immune & Collagen Support

L-Lysine 500mg by NOW Foods delivers a pure, pharmaceutical-grade dose of L-Lysine — an essential amino acid that the body cannot produce on its own and must obtain through diet or supplementation. L-Lysine plays a critical role in collagen synthesis, immune function, calcium absorption, and is widely used for its antiviral properties, particularly against the Herpes Simplex Virus (HSV).

Key Benefits:

• Supports collagen synthesis for healthy skin, tendons, and connective tissue
• Antiviral properties – helps reduce frequency and severity of cold sores (HSV-1)
• Supports calcium absorption and bone health
• Essential for carnitine production and fat metabolism
• Supports immune function and antibody production

Key Ingredients (per capsule):

• L-Lysine – 500mg – an essential amino acid serving as a direct precursor to collagen cross-linking, carnitine biosynthesis, and immune antibody production; competes with arginine for absorption, which is the basis of its antiviral effect against HSV

How to Use:

Take 1 capsule 2 to 3 times daily, preferably on an empty stomach. Consult your healthcare provider for personalized dosing.
