The vitamin D questions: how much do you need and how should you get
it?
====================================================================

Wolpowitz D, Gilchrest BA.

Department of Dermatology, Boston University School of Medicine,
Boston, Massachusetts 02118, USA.

UV radiation is a well-documented human carcinogen, indisputably
linked to the current continued increased rate of skin cancer. UV
radiation is also responsible for cutaneous synthesis of vitamin (vit)
D3, a substance that is then sequentially hydroxylated in the liver
and kidney to yield 1,25(OH)2 vit D, a hormone critical for calcium
homeostasis and skeletal maintenance. Because the UV action spectra
for DNA damage leading to skin cancer and for vit D photosynthesis are
virtually identical, the harmful and beneficial effects of UV
irradiation are inseparable. This has given rise to the argument that
sun avoidance, with a goal of skin cancer prevention, may compromise
vit D sufficiency. Public interest in this matter has been heightened
in recent years by multiple studies correlating the level of 25-OH vit
D, the readily measurable "storage" precursor form of the vit, with a
variety of benefits separate from skeletal health. Although the
studies are of variable quality and all alleged treatment benefits are
based on dietary supplementation with vit D, not on increased sun
exposure, they have been interpreted by some as support for advocating
increased sun exposure of the public at large. The goal of this review
is to provide a detailed, balanced, and referenced discussion of the
complex literature underlying the current popular interest in vit D
and sun exposure for the purpose of increasing vit D photosynthesis.
We review the nomenclature, metabolism, and established functions of
vit D; the evidence supporting the less well-established but purported
vit D effects; the concept of vit D insufficiency; populations at risk
for vit D deficiency; and finally the risk/benefit of obtaining vit D
from cutaneous photosynthesis versus diet or supplementation.
