Hi Rob. Several studies suggest that supplementing with the amino acid lysine may help reduce the number of recurring outbreaks of cold sores.

A few studies also suggest that lysine may help to shorten the length of an outbreak.

Taking lysine or obtaining more lysine in your diet, from foods such as chicken, fish, eggs, and potatoes, may assist recovery and reduce the chance of recurrent breakouts of this herpes infection.

It’s always best to consult a health professional before taking supplements, particularly if you take prescription medication or have any health conditions. I would also stress that zinc is supportive for the immune system and stress management techniques are also important – often cold sore outbreaks occur when the nervous system is overwhelmed.
