Abstract
Conclusion
The effect of pantothenic acid in cure of nutritional achromotrichia is difficult to assess at present because other factors are clearly involved. Certain liver extracts providing as low as 40 μg of pantothenic acid per day caused complete remission, while the effect of synthetic d-calcium pantothenate was negligible at best. The addition of d-calcium pantothenate to extracts low in this factor, however, increased their anti-graying potency. Age or weight increase of animals did not seem to influence the curative effect of supplements for graying.
Although rats were raised to maturity on highly synthetic diets supplying adequate d-calcium pantothenate, successful matings were not observed.
