Food supplements and psoriasis
Generally, food supplements are not necessary to be taken daily as long as your diet is complete and well-rounded. However, people with special diets, eating disorders, or metabolic disorders may be lacking adequate amounts of important vitamins, minerals, and macromolecules that are necessary for normal bodily functions. In these cases, food supplements are of significant use in treating symptoms of nutrient deficiency.
In psoriasis, there is no apparent effect on normal metabolism and absorption of nutrients, although some people with the disease are recommended to change their diet in order to avoid food allergens which may trigger their flare ups. People with psoriasis may take supplements in order to improve the condition of their skin, taking supplements which contain vitamin C, E, and biotin.
Biotin is a type of B vitamin, and acts as a coenzyme in metabolic reactions that take place in the body. It is a component of many multivitamin preparations, especially those geared towards improving healthy skin, hair, and nail growth. There is some evidence that suggests biotin can be used to treat peripheral neuropathy and diabetes. For people with psoriasis, biotin supplementation may be of benefit in order to help heal their skin and make their nails stronger to prevent breaking and pitting. The use of biotin supplements is not necessary in most cases because it can be found in common foods like eggs, milk, and whole grains, and the body effectively recycles biotin, so deficiency of biotin is quite rare. However, due to the water-solubility of B vitamins, even a large excess of biotin is harmless and has no value given for its toxicity level.
