lysine

Protein building block

Lysine is an essential amino acid—one the human body cannot produce and must obtain from food.

It's abundant in meat, fish, eggs, and dairy, but limited in grains, making it a common concern in vegetarian nutrition.

Lysine plays roles in protein synthesis, calcium absorption, and immune function.

Lysine supplements are sometimes used to prevent cold sores.
