Itchy skin can be uncomfortable and have a number of causes, including dry skin, allergies, eczema, lice, hives, chickenpox, anemia, cancer, pregnancy, allergic reactions and nerve disorders. Scratching is likely your first instinct when you have an itch. Scratching often provides temporary relief. The key to treating itching is to treat the underlying cause. Certain vitamins, such as vitamins A, C, E and H, may also help to alleviate itching. Consult your doctor prior to beginning a vitamin regimen.
Vitamin A is a fat-soluble vitamin -- meaning it is stored in the fat cells of your body. Vitamin A plays a role in nourishing healthy skin. Vitamin A helps to promote the production of sebum. Sebum is a natural oil made by your body that helps to keep your skin hydrated. By keeping your skin hydrated, you are less likely to experience dry and itchy skin. Vitamin A can be supplemented or consumed through a well-balanced diet. Food sources of vitamin A include cheese, squash, spinach and eggs.
Vitamin C -- or ascorbic acid -- is a water-soluble vitamin that constantly needs to be replenished. Your body does not store vitamin C. This vitamin aids in the production of collagen. Collagen is a protein substance necessary for the development and healing of skin and tissue. A powerful antioxidant, vitamin C can also help to protect your body -- including your skin -- from free radicals and irritants in the environment -- such as smoke, according to "The Vitamin Book." Exposure to free radicals and environmental factors can speed up the aging process and lead to wrinkles and fine lines. A lack of vitamin C in your system can lead to skin that is dry, rough and itchy. You can take vitamin C as a supplement or consume vitamin C through your diet -- red peppers, cranberries, kiwi, oranges, tomatoes, spinach, mangoes, potatoes and oranges all contain vitamin C.
Vitamin E is a fat-soluble vitamin known for its antioxidant properties. Vitamin E can help to provide relief to itchy skin by keeping your skin healthy and fresh and by improving the texture of your skin. This is done by protecting your skin from free radical damage as well as damage from environmental pollutants. Free radicals and environmental pollutants can have a negative effect on your skin -- they act as irritants and can speed up the aging process. You can supplement vitamin E or consume vitamin E through your diet. Food sources of vitamin E include nuts, vegetable oil, wheat germ, green vegetables and whole grains.
Vitamin H -- also known as biotin -- can help promote healthy skin and prevent itching. While a vitamin H deficiency is rare, symptoms can include dry eyes, fatigue, depression, insomnia, hair loss, cracking at the corners of your mouth and dry, scaly skin. Vitamin H is important in metabolizing fats and proteins to be used by the body, according to "The Vitamin Book." As a result, you are likely to experience healthier skin, eyes and hair as well as a healthier liver and nervous system. Vitamin H can be supplemented or received through such food sources as mushrooms, egg yolks, nut butters and black-eyed peas.
