What is L-Lysine? L-Lysine is an essential amino acid that acts as a building block for proteins such as collagen and elastin.* This amino acid can be found in protein rich foods like meat and dairy, and also be added to your routine with a nutritional supplement. Supplementing with L-Lysine: There are many supplement forms of Lysine such as powder, capsules, liquid, tablets, pills, and more.
