Lysine is a very important amino acid for the body, as it has antiviral action that helps to fight virus infections and also facilitates the absorption of calcium. However, this amino acid is not produced by the human body, which means that it needs to be ingested through food.

Foods rich in lysine are mainly milk, soy and meat. The consumption of this type of food is especially recommended for people with herpes, because it helps to decrease the replication of the herpes simplex virus, reducing its recurrence, severity and recovery time.

What is lysine for?

Lysine is used to fight virus infections, as it has antiviral properties and is very effective for osteoporosis, as it helps to increase calcium absorption. In addition, it is important in bone and muscle development in children, as it participates in the activity of growth hormone.

Recommended daily amount

The recommended daily amount of lysine is approximately 30 mg per kg of weight, which for an adult of 70 kg means an intake of about 2100 mg of lysine per day.

Lysine is found in food, but depending on the diet, the amount may not be sufficient and, therefore, supplementation with 500 mg per day may also be advised.
