L-lysine is an essential amino acid found in certain foods and supplements. It has been suggested that L-lysine may be beneficial in preventing or helping with Shingles a viral infection caused by the reactivation of the varicella-zoster virus. However, the current medical research on L-lysine for Shingles is limited and inconclusive.
Some studies have investigated the potential antiviral properties of L-lysine, suggesting that it may help inhibit the replication of the varicella-zoster virus. These studies have shown mixed results, with some indicating a potential benefit, while others found no significant effect on Shingles symptoms or recurrence rates. There is also a lack of well-designed clinical trials to confirm the efficacy of L-lysine specifically for Shingles
