Best L-Lysine Supplements

L-Lysine is an essential amino acid that helps with protein production, enzyme function, and immune support. Your body can't make it on its own, so you need to get it from food or supplements.Many people use L-Lysine supplements to manage herpes outbreaks and reduce cold sores. Cold sores come from the herpes simplex virus type 1 (HSV-1), which spreads through direct contact like kissing. The right L-Lysine supplement can help prevent outbreaks and reduce their severity.

How L-Lysine Helps Manage Herpes Outbreaks and Prevent Cold Sores

Herpes simplex needs arginine (another amino acid) to replicate in your body. Lysine interferes with arginine absorption in your intestine, making it unavailable to the virus. While lysine won't cure herpes, it can slow or stop HSV-1 replication.Research shows that lysine reduces the frequency of infections and healing time. A 2005 study found that lysine sped up healing for 87% of participants, shortening recovery from 21 days to just 6 days. Here are some of the best L-Lysine supplements available.
