NOW Foods L-Lysine 500 mg – 100 Veg Capsules

NOW Foods L-Lysine 500 mg provides a pharmaceutical-grade essential amino acid in convenient vegetable capsules. Because the body cannot produce lysine, it must be obtained through food or supplementation. Each capsule supplies 500 mg of L-Lysine from 637 mg of L-Lysine hydrochloride to support protein production, collagen synthesis, and daily immune wellness. L-Lysine is required for maintaining collagen and elastin, important structural proteins found in connective tissues such as skin, tendons, and bones. It also serves as a precursor to carnitine, which supports normal fat metabolism and cellular energy production, and it helps maintain healthy immune and cardiovascular function as part of a balanced lifestyle. This vegan and vegetarian formula is non-GMO, halal, and kosher, and is also dairy free, egg free, soy free, nut free, and made without gluten. For a longer-lasting supply of the same formula, see NOW L-Lysine 500 mg, 250 Veg Capsules, or browse the full Vitamins A–Z collection.

Why Choose NOW Foods

Lysine is one of the amino acids the body cannot make on its own, so a clearly labeled, single-ingredient source matters. NOW Foods delivers exactly that: 500 mg of pharmaceutical-grade L-Lysine per vegetable capsule, in a clean vegan formula with no unnecessary extras, packaged and quality tested in the USA. The 100-capsule bottle is a practical starting size for adults who want straightforward amino acid support, and the bottle itself is made from 100% post-consumer recycled resin.

Because lysine is a precursor to carnitine, many shoppers pair it with NOW Acetyl-L-Carnitine 750 mg for complementary cellular energy support.
