Does Lysine help with fever blisters?

Yes, lysine can help with fever blisters. Lysine is an amino acid that is essential for the body to produce proteins. However, the body cannot produce lysine on its own, so it must be obtained from food. Lysine has been shown to help reduce the frequency and severity of fever blisters by inhibiting the replication of the herpes simplex virus, which is the virus that causes fever blisters.

There is some evidence to suggest that lysine can help to reduce the severity and frequency of fever blisters. However, more research is needed to confirm the effectiveness of lysine for this purpose.

Lysine is available as a dietary supplement in the form of tablets, capsules, and powders. It can also be found in foods such as meat, fish, cheese, eggs, and beans.
