Vitamin D3 and Activation into ...
Discussion Skin is the physiological site of vitamin D3 photoproduction as it
contains ample amounts of 7-DHC (Holick, 2003; Norman, 1998; Holick, 1981)
and is exposed to UVB irradiation in vivo. Vitamin D3 photo-producing rays with a

Vitamin D Research
During exposure of human skin to sunlight, UVB (290-315 nm) converts the
precursor, 7-dehydrocholesterol (provitamin D3) in the epidermis into previtamin
D3, which is then isomerized to vitamin D3. Previtamin D3 can also isomerize
into ...

54-1). Vitamin D2 differs structurally from vitamin D3 by having a double bond
between the carbon positions 22 and 23 and a methyl group at C-24. Both

66 From 6 months after switching to vitamin D3, BMD was found to be
significantly different, as compared to the follow-up group (6 months, P<0.05; 12

There are four important variables that collectively determine the amount of
vitamin D3 that will be photochemically produced by an exposure of skin to
sunlight. The two principal determinants are the quantity (intensity) and quality (
