Vitamin B-12 & Psoriasis

Psoriasis is a skin disorder characterized by raised, pink lesions covered by silvery scales that commonly affects the scalp, elbows and knees. In some cases joints are also affected, and this condition is known as psoriatic arthritis. More than 6 million Americans are diagnosed with this condition, University of Maryland Medical Center indicates. Conventional therapy includes medication. Researchers have investigated Vitamin B-12 for potential therapeutic benefits in psoriasis sufferers and recorded some positive findings. If you consider taking this supplement, first talk to your doctor.

B-12 Function and Sources

Vitamin B-12, or cobalamin, is a water-soluble vitamin belonging to the B group of vitamins. It plays a key role in the production of red blood cells, the function of the nervous system and the metabolism of fats, carbohydrates and proteins. Dietary sources of vitamin B-12 include eggs, meats and dairy products. B-12 is also available as a supplement.

Symptoms of B-12 Deficiency

Common symptoms of B-12 deficiency are numbness, tingling in the arms and legs, and weakness. Vegetarians and those who have impaired B-12 absorption due to surgeries of the stomach or intestines are prone to develop a deficiency in this nutrient. Vitamin B-12 deficiency has also been linked with psoriasis in preliminary studies; however, more research is needed to confirm this finding.

Psoriasis and B-12 Deficiency

Low blood levels of vitamin B-12 have been recorded in patients with psoriatic arthritis, according to a study featured in the January 2004 "Rheumatology International." This study evaluated more than 200 participants diagnosed with different forms of arthritis, including psoriasis arthritis. The authors found that 35 percent of the subjects with psoriasis were deficient in this nutrient.

Psoriasis and B-12 Therapy

An ointment based on vitamin B-12 and avocado oil appears to be beneficial in treating skin lesions associated with plaque psoriasis, a research study featured in the 2001 issue of "Dermatology" indicates. The authors suggest that this B-12-based ointment is well-tolerated and possibly effective long term for managing this form of psoriasis.

Considerations

Consult a qualified health care professional to find out the optimal dosage of vitamin B-12 that may help manage your condition. Other vitamins, herbs and homeopathic remedies along with a modified diet may also help improve symptoms of psoriasis. This nutrient does not replace and should not be used to replace standard therapy prescribed for psoriasis. Vitamin B-12 is not approved by the U.S. Food and Drug Administration to treat psoriasis.
