L-Lysine at 150-3,000 mg per day provides an essential amino acid for the maintenance of good health and helps in the formation of collagen, and at 1,000-3,000 mg per day, helps reduce the recurrence of herpes simplex virus (HSV) infection (e.g. cold sores) (3).

A study examined the efficacy of long-term prophylactic lysine supplementation. Twenty-six volunteers with a history of frequently recurring herpetic lesions completed a 12-month double-blind crossovers study. Participants were randomly divided into experimental and control groups. Each was given a 6-month supply of tablet containing either 500 mg L-Lysine mono hydrochloride or placebo 2 times a day. In most instances, members of the lysine group reported significantly fewer lesions than the control group. Similarly, those who were taken off lysine supplementation generally showed a significant increase in lesion frequency. Quantitative hematologic measurements revealed the most clinically useful relationship. Data from this sample population indicated that when a person's serum lysine concentration exceeded 165 nmol/ml there was a corresponding significant decrease in recurrence rate. Conversely, the frequency rate increased significantly as concentration levels fell below 165 nmol/ml. These results suggest that prophylactic lysine may be useful in managing selected cases of recurrent herpes simplex labialis if serum lysine levels can be maintained at adequate concentrations (4).
