Supplements for Cold Sores

Cold sores are caused by the herpes simplex virus, and once a person develops a blister, the virus is forever present. Regular cold sore breakouts are uncomfortable and unsightly, and the virus is also highly contagious. Stress, sunburn and changes in immune system function can lead to cold sore breakouts. Fortunately, there are several dietary and herbal supplements that may prevent cold sore breakouts, alleviate symptoms or accelerate the healing process.

Lysine

• Lysine is an amino acid that is required for growth and development. According to vitamins-supplements.org, "The most promising application of lysine is its use in managing and preventing painful and unsightly herpes sores caused by the herpes simplex virus (HSV)." Lysine slows the progression of the virus, which may lead to shorter outbreaks. Lysine is available in tablet form, and it occurs naturally in a variety of foods, such as meat, cheese, nuts, eggs, soybeans, cod and sardines.

Vitamin C

• Vitamin C has a variety of health functions, including cold sore relief. Vitamin C improves overall immune system function, which may help to prevent outbreaks in the first place. Additionally, according to supplementnews.org, vitamin C is an effective topical treatment for cold sores, because it helps accelerate wound healing. Combine a vitamin C supplement with a bioflavonoid supplement for optimal results.

Lemon Balm

• Lemon balm can be an effective topical cold sore treatment when prepared in its concentrated form. The herb, whose botanical name is Melissa officinalis, helps shorten breakouts and relieves itching, stinging and redness of cold sores. Supplementnews.org recommends a 70 to 1 ratio preparation for optimal cold sore relief. Lemon balm ointments can usually be found in health stores.
