Quick answer
L-lysine is one of the nine essential amino acids, so your body can't make it and you need to get it from food. Meat, fish, dairy, eggs and legumes are rich sources, while most grains are relatively low. Lysine supplements, such as MAYN L-Lysine 1000mg, provide a measured amount.

Why is lysine "essential"?
Essential means your body can't make it, so it must come from your diet. See Essential vs Non-Essential Amino Acids for the full list.
Lysine in food
| Food group | Lysine content |
|---|---|
| Meat, poultry and fish | High |
| Dairy and eggs | High |
| Legumes (lentils, beans, soy) | High |
| Nuts and seeds | Moderate |
| Wheat, rice and corn | Lower |
Because grains are relatively low in lysine, plant-based eaters often pair grains with legumes, for example rice and beans.
Reading a lysine label
Lysine is often sold as L-lysine HCl (hydrochloride). Labels usually state the amount of L-lysine per serve.
Tip: Look for "L-lysine". The L-form is the one found in food.
