L-Lysine and L-Lysine for Cold-sore (HSV) recurrence
Each entry’s own grades, side by side. A grade says how strong the evidence is for one outcome — it does not rank one entry over the other.
Compound or practice
L-Lysine
An essential amino acid with modest evidence for reducing cold-sore (herpes) recurrences.
Grade C1 graded outcomerevised Jul 10, 2026
A structured monograph in Prometheus's bundled library. Its grades are the monograph's own reading of the evidence, not a peer-reviewed review.

Graded in both
Outcomes are matched by name. Two entries can describe the same outcome in different words, so one listed further down may still be graded in the other.
