Lysine

Lysine is an essential amino acid, which means your body cannot make it and you must get it from food or supplements. Your body uses lysine to build protein and collagen, absorb calcium and support immune function. It is especially popular for healthy lips and skin and for immune support.

This collection includes L-lysine capsules and tablets from 500 to 1,000 mg, lysine powder and lysine combination formulas from practitioner brands such as Pure Encapsulations, Thorne, Klaire Labs, Xymogen, Vital Nutrients, Allergy Research Group, Progressive Labs, NOW and NutriDyn.

How to Choose a Lysine Supplement

• Capsules and tablets: 500 to 1,000 mg per serving covers most needs. L-Lysine 500 mg by Pure Encapsulations is our top seller.
• Powder: Makes larger or adjustable amounts easy and costs less per gram.
• Lysine with monolaurin: L-Lysine Monolaurin by Solaray pairs lysine with a compound from coconut for immune support.
• Lysine Extra: Combination formulas such as Lysine Extra by Vitanica add herbs and nutrients for lip and immune support.

Most people take 1,000 to 3,000 mg a day, often split into two or three doses. Foods rich in lysine include meat, fish, eggs, dairy, beans and lentils, so vegans and vegetarians are more likely to fall short. See also amino acids and immune support.
