Vitamin B12 and Folic Acid
Both vitamin B12 and folic acid have been found to be deficient in individuals with vitiligo. The relationship between these nutrients and the development and treatment of vitiligo are unclear, though many hypotheses exist. Vitiligo is associated with autoimmune diseases and pernicious anemia. However, in pernicious anemia there is a decreased absorption of Vitamin B12. This may be a causal relationship. In a study of 100 patients with vitiligo, supplementation with B12 and folic acid, concurrent with sun exposure, caused a repigmentation in 52% of the cases. Six patients had complete repigmentation. The spreading of lesions was ceased entirely in 64% of the patients. Results were more significant when there was an inclusion of UVA exposure. In another study, folic acid and B12 status was measured in individuals with vitiligo and was found to be lower than normal subjects. Supplementation with both B12 and folic acid in this group also resulted in repigmentation.
Vitamin E and CoQ10
It has been observed that individuals with vitiligo have an imbalance in the anti-oxidant systems of skin. This supports the theory that oxidative damage (via the sun) may play a role in the pathogenesis of melanocyte destruction and the subsequent development of vitiligo. Free radicals are elevated in the melanocytes of individuals with vitiligo. Anti-oxidants that are specific to cell membranes are also found to be extremely low. One study measured the oxidative stress in the epidermis of individuals with vitiligo and found it to be increased. Also measured and found to be deficient were the anti-oxidants that are usually present to protect the cell membrane from damage, namely, Vitamin E and CoQ10. This supports the theory that the supplementation of anti-oxidants aids in protecting skin cells from the damage caused by free radicals.
Vitamin D3
Vitamin D is nutritive to the skin. It helps to maintain the integrity of cellular membranes. It is also involved in the production of melanin and directly affects cell growth and differentiation. Topical treatments of vitamin D3 have been proven to be an effective treatment for vitiligo. The mechanism of action may be associated with the immunomodulatory effect of vitamin D3. In a small study, 6 of 15 patients had greater than 30% clearance of vitiligo after a short treatment period. The application was combined with sun exposure for 30 minutes. Results were more positive in individuals who had been diagnosed within the previous five years before study. In considerably larger clinical study, 77% of patients had a 30-100% improvement in repigmentation after treatment for 3-9 months with both topical Vitamin D3 and UVA light. These results were consistent with conventional therapies that employ PUVA treatments.
Phenylalanine
Phenylalanine is an amino acid that has been effective in the treatment of vitiligo. Although the mechanism is not fully understood, it is postulated that phenylalanine stimulates the production of melanin by the melanocytes. Oral and topical phenylalanine has been used with positive results. In one study, the oral supplementation or L-phenylalanine for six months resulted in an improvement (repigmentation) in 90% of the cases. 68% of these individuals had greater than 75% improvement. The areas on the face and trunk were affected most. In an uncontrolled trial, the combination of oral and topical phenylalanine in conjunction with sun exposure, resulted in complete repigmentation in 57% of total cases (n=171). Results are best when oral and topical phenylalanine is combined with regulated amounts of UV exposure.
Ginkgo Biloba
Ginkgo biloba is a potent anti-oxidant due to its high flavonoid content. Because of its free radical quenching abilities, it has been looked at as a possible therapy for vitiligo. In one recent study, supplementation with ginkgo biloba extract resulted in significant results. All of the participants had a cessation of disease progression, while 10 patients had complete repigmentation.
