Vitamins & Nutritional Supplements for Vitiligo

Supplementation with the amino acid L-phenylalanine (LPA) may have value when combined with ultraviolet (UVA) light therapy. Several clinical trials, including one double-blind trial, indicated that LPA (50 mg per 2.2 pounds of body weight per day—3,500 mg per day for a 154-pound person—or less) increased the extent of repigmentation induced by UVA therapy. LPA alone also produced a more modest repigmentation in some people. A study of vitiligo in children reported that LPA plus UVA was an effective treatment in a majority of the children.

A group of Spanish doctors reported on their experience using LPA over a six-year period. Some of the 171 people with vitiligo received LPA (50 or 100 mg per 2.2 pounds body weight per day) for up to three years. Between April and October of each year, participants also applied a 10% LPA gel, prior to exposing their skin to the sun for 30 minutes. Some improvement was seen in 83% of participants, and the results were rated as good in 57% (75% improvement or better)...
