Principal Proposed Uses
Lysine is an essential amino acid, one that you need to get from food. Some evidence suggests that supplemental lysine may be able to help prevent herpes infections (cold sores and genital herpes).
Most people need about 1 g of lysine per day. The requirement may be greater for athletes and people recovering from major injuries, especially burns. The richest sources of lysine are animal proteins such as meat and poultry, but it is also found in dairy products, eggs, and beans.
A typical therapeutic dosage of lysine for herpes infections is 1 g three times daily. You can take this as a regular part of your diet in hopes of preventing herpes flare-ups, or, perhaps, at the first sign of an attack. Although the evidence isn't strong, there may be some advantage to restricting your intake of foods that contain a lot of arginine, such as chocolate, peanuts, other nuts and seeds, and, to a lesser extent, wheat.
What Is the Scientific Evidence for Lysine?
Although some are promising, none of these studies are large enough to give conclusive answers. At this point, more evidence is needed to determine whether lysine is effective for preventing herpes simplex.
