The evidence in words
How much to take
1–3 g/day for prevention; higher at outbreak onset.
Timing & separation
There are no strict timing conflicts on record for L-Lysine; consistency matters more than the exact hour for most goals.
Why the dose is what it is
Lysine competes with arginine, which the herpes virus needs to replicate — the basis for the lysine/arginine-balance approach.
Bottom line
A cheap, low-risk option that helps some people get fewer cold sores. Worth a trial if you're prone to them.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
