"This increasingly common abnormality is another symptom of malnutrition, and has been corrected by giving 150 to 300mg of pantothenic acid daily, or 1000 mg or more of
PABA. Applying PABA ointment to the depigmented areas sometimes brings marked improvement. This condition usually clears up after the diet is unusually high all the natural sources of B vitamins. I once told a 30 year old woman with severe vitiligo that liver would probably help her more than any other food. A week later she joyously returned to show me that not a trace of it remained, but she had eaten a 1/4 pound of raw liver, frozen, diced and covered with catsup, at each meal. Several other such persons have had the condition clear up slowly on a more appetizing diet."
Adelle Davis, 1965, referring to research c 1945-1950

Those links are hogwash BS.

People who pay attention will note that B vitamins and especially pantothenic acid are prime factors in adrenal function, hence cortisol etc.
While cortisol may help alleviate pain, the pain is better controlled by not letting it start, and by personal experience the same B vitamins that prevent vitligo will do that. And V-C, calcium, magnesium will also stop pain from starting, and control it if it does start.
