NOW Foods L-Lysine is an essential amino acid supplement that supports collagen and elastin synthesis, immune function, and cardiovascular health.
Lysine is an essential amino acid that must be obtained through the diet or through supplementation. Lysine is necessary for the production of all proteins in the body and is required for the maintenance of the structural proteins collagen and elastin, which form all connective tissues such as skin, tendon, and bone. Lysine is also a precursor to carnitine, which is needed for fat metabolism and energy production. In addition, lysine may help to support a healthy immune system and proper cardiovascular function.
NOW® L-Lysine is a pharmaceutical-grade essential amino acid.

Frequently Asked Questions
NOW Foods L-Lysine is a dietary supplement containing L-lysine, an essential amino acid that the body needs for protein production, tissue repair, and normal growth.
Potential benefits include supporting protein synthesis, collagen formation, tissue repair, and normal immune function. Supplementation is most useful when dietary intake is insufficient.
L-lysine supports normal protein production. However, there is limited evidence that taking extra lysine improves hair growth unless a nutritional deficiency is contributing to hair loss.
Lysine is necessary for muscle protein production. However, muscle growth also depends on adequate overall protein intake, resistance exercise, and sufficient calories.
Lysine contributes to collagen production, which helps maintain skin structure. However, taking a supplement has not been proven to improve skin appearance in everyone.
Possible side effects include nausea, stomach discomfort, and diarrhea, particularly at higher doses.
