Tag: Who should avoid lysine

According to research, most people can safely obtain adequate lysine from their regular diet alone, but not everyone can safely take L-lysine supplements. While beneficial for some specific conditions, concentrated L-lysine supplements carry risks and contraindications that exclude certain individuals and health conditions.

Lysine is an essential amino acid, meaning the body cannot produce it on its own and it must be obtained through diet or supplementation. While widely used for its purported benefits, particularly for managing cold sores, it is crucial to understand if there are any negatives to L-lysine, especially with high or prolonged use.
