Vitamins like lysine, zinc oxide, A, B, C, and E can help prevent or treat cold sores. They can be taken orally, applied topically, or found in food. Consult a doctor for appropriate dosages.
Cold sores, also known as fever blisters, can be uncomfortable and also embarrassing. There are several vitamins that can be used to help prevent or treat this condition. Some of the most commonly used vitamins for cold sores include lysine, zinc oxide, and vitamins A, B, C, and E. There are several ways to use vitamins for cold sores, including oral medications, food, or topical preparations. Any questions or concerns about the appropriate dosages of the various vitamins for cold sores should be discussed with a doctor or other medical professional.
Lysine is one of the most commonly recommended vitamins for cold sores. This vitamin helps prevent outbreaks of cold sores and can also help reduce the growth of existing cold sores. Some foods that contain lysine include potatoes, beans, and brewer’s yeast. This nutrient can also be added to topical ointments designed to be applied directly to the fever blister.
Zinc oxide can be found over the counter at most drug stores and is among the popular vitamins for cold sores. Zinc oxide is available as an ointment and is applied directly to the cold sore. This method of treatment provides a relaxing sensation while helping to dry out the fever blister.
Vitamin A can be used to help prevent infections that are sometimes caused by the presence of cold sores. Some foods that contain high levels of vitamin A include sweet potatoes, carrots, and spinach. Vitamin B, especially vitamin B6, helps strengthen the immune system and prevent infections. Foods that contain this vitamin include bananas, garlic, and mushrooms.
Another important vitamin for cold sores is vitamin C. This vitamin has natural antiviral properties and helps in the healing process. Citrus fruits, nuts, and dark green vegetables are rich in vitamin C. Nutritional supplements are also available for those who do not get enough of this vitamin from their diet.
Vitamin E can be particularly helpful in treating cold sores, as it promotes healing and stimulates the production of white blood cells. This supplement can be taken in oral tablet form, although the topical form may be more beneficial. Vitamin E oil can be applied directly to cold sores for additional soothing effects. For those who want to add this vitamin to their diet, foods like almonds, sunflower seeds, and broccoli contain significant amounts of vitamin E.
