Life Extension L-Lysine 620 mg — 100 Vegetarian Capsules

L-lysine is an essential amino acid — meaning the body cannot synthesize it and must obtain it from diet or supplementation. Lysine is critical for collagen synthesis, healthy immune cell function, calcium absorption, and antiviral defense. It is particularly valued for its role in supporting healthy collagen production for skin, bone, and connective tissue, and for its well-documented antiviral properties.

Each bottle contains 100 vegetarian capsules for a 3-month supply at standard dosing.
