We explored the effectiveness of lysine supplementation in treating herpes infections through a survey of 1,543 participants after a six-month trial. The findings revealed that a substantial 84% reported that lysine helped prevent recurrences or reduced the frequency of outbreaks.
Notably, only 8% of users described their symptoms as severe while taking lysine, compared to 79% who felt that way without it. Healing times improved significantly; 83% felt lesions healed in five days or less with lysine, while 90% said healing took longer without it. Overall, 88% regarded lysine as an effective treatment.

Effective shingles control
Excellent results! I have tried more expensive brands, but Solgar has proven to be the most effective. I take it to manage shingles, which can sometimes appear as a cold sore or cause headaches at the base of the skull due to stress and poor diet, even without visible blisters.
