Psoriasis is a common skin condition characterized by the presence of thick, red skin with flaky, white patches called scales. This condition commonly begins between 15 to 35 years of age and may be triggered by a variety of factors, including infections, dry skin, injury or chronic use of certain drugs. Topical and systemic medications and light therapy is used to control the symptoms and prevent infections. The use of certain vitamins and natural supplements may be beneficial.
Vitamin A
Vitamin A-based medications called oral retinoids, such as acitretin and isotretinoin, are the first-line treatment for adults with severe psoriasis, and according to the University of Maryland Medical Center, these drugs also have anti-inflammatory properties and may improve arthritis associated with psoriasis as well. Oral retinoids are among the safest drugs that can be used to treat severe psoriasis, although side effects such as bone pain, fatigue, headache and liver damage may occur due to excess of vitamin A. The University of Maryland Medical Center recommends exercise, a low-fat diet and fish oils to control the side effects.
Folic Acid
Folic acid is part of the vitamin B complex that can be obtained from foods such as green leafy vegetables, fruits, dried beans, peas, nuts, and enriched grains and cereals. Apart from causing anemia, low levels of folic acid are also associated with psoriasis, according to a study published in the December 2006 "British Journal of Dermatology." Modification of the diet to ensure sufficient folic acid intake is recommended to manage psoriasis treatment and prevention.
Vitamin D
Vitamin D is another fat-soluble vitamin essential for maintaining healthy bones. It can be obtained from foods such as milk, cheese, meat, eggs and poultry. Exposure to sunlight can also lead to the production and activation of significant amounts of vitamin D in the body. However, deficiency of this vitamin is common in strict vegetarians and vegans and in individuals with indoor lifestyles, and another study published in the October 2005 "British Journal of Dermatology" has found vitamin D deficiency and psoriasis are closely related. Change in the diet to include foods rich in vitamin D and exposure to sunlight for at least 10 minutes per day may be useful. Vitamin D supplements may be recommended to individuals who cannot get the required amounts of the vitamin naturally.
