Generally accepted with some debate
"Lysine's role in herpes management is supported by several studies, but the evidence is not definitive. Its general role in immune function is well-established, but the impact of supplementation in healthy individuals is less clear. More research is needed to fully understand its benefits."
Lysine is an essential amino acid, meaning your body can't produce it, and you must obtain it from your diet or supplements. It's primarily used to help manage herpes outbreaks and support immune function. Some studies suggest it works by interfering with the replication of the herpes simplex virus. It also supports collagen production.
