Can Lysine Treat Cold Sores?

Q:
Can lysine treat cold sores?

A:
There is no cure for cold sores, but this condition can be treated with common antiviral medication, such as valacyclovir (Valtrex) or acyclovir (Zovirax). You can use lysine in addition to antivirals, an essential amino acid found in protein. It isn’t produced in your body, so you must consume it through an oral supplement or diet.

Common foods rich in lysine include:

  • beef
  • chicken
  • codfish
  • eggs
  • parmesan cheese
  • pork
  • sardines
  • soybeans
  • spirulina
  • turkey
  • yogurt
