Natural Factors L-Lysine 500 mg (90 VCaps)

SKU: NF02823

Free-Form Amino Acid for Cold Sore Prevention and Healing

What It Does

L-Lysine 500mg provides natural support against cold sores while helping your body repair tissue and form collagen. This essential amino acid works by competing with arginine, which herpes simplex virus needs to replicate, helping keep outbreaks in check.

Why It Works

SUPERIOR BIOAVAILABILITY: Free-form amino acid absorbs more effectively than lysine from food sources alone.
TARGETED SUPPORT: 500mg per capsule delivers therapeutic levels to help reduce cold sore recurrence and healing time.
ESSENTIAL FUNCTION: Your body cannot manufacture lysine — supplementation ensures adequate levels for tissue repair and immune support.

What's Inside

Clean vegetarian formula contains no corn, soy, wheat, gluten, or yeast. Each capsule delivers pure L-Lysine hydrochloride with minimal inactive ingredients.

Why we carry it: Natural Factors produces pharmaceutical-grade amino acids with third-party testing for purity and potency.
