What is L-Lysine 1000mg Free Form 50 Tablets?

L-Lysine 1000mg Free Form 50 Tablets is a amino acids product by Solgar in tablet form, scoring 80.0/100 on AIScored.

  • L-Lysine is one of the essential amino acids that serve as building blocks of protein, forming the structure of cells and tissues throughout the body — including muscles, organs and skin.
  • Because the body cannot produce essential amino acids on its own, they must come from food or supplementation.
  • Getting precise amounts of lysine from diet alone can be difficult, making a measured supplement a practical way to maintain consistent levels.
  • Each Solgar tablet delivers a 1000mg dose of free-form L-Lysine.
  • Suitable for adults aged 18 and over.
