Supplementing with which of these can be dangerous?

a. Vitamin C, ascorbic acid
b. Vitamin E, alpha tocopherol
c. Vitamin A, beta carotene
d. Vitamin D, cholecalciferol

ANSWER (B): Supplementing with only the alpha tocopherol form of Vitamin E can be dangerous. We use a mixed tocopherol formula to provide balanced supplementation.
Vitamin A (beta carotene form) is safe and natural. The retinol form of Vitamin A should be closer to the RDA.
Vitamin C (ascorbic acid) is a safe concentrated form.
Vitamin D (cholecalciferol) is D3 and a safe form that is familiar to the body.
