Vitamin D-3 by Metabolic Maintenance Vitamin D is the most active form of Vitamin D and is equivalent to the Vitamin D formed on our skin from ultraviolet B radiation. Darker skin pigmentation, use of sunscreens (SPF of 8 or more), geographic latitude above 30, and aging can all significantly inhibit the skins production of vitamin D-3.*

Metabolic Maintenance suggests taking 1 capsule of Vitamin D-3, daily, with meal, as a dietary supplement, or as directed by a healthcare practitioner.
