Vitamin D is vital to the health of your skeletal
and immune systems. The body manufactures
this essential vitamin through sun exposure, making it
difficult to obtain adequate amounts of vitamin D during
the cloudy winter months or when sunscreen is
used.
Vitamin D comes in two forms: D2 and D3. Of the
two, D3 is more bioactive. The body synthesizes vitamin
D3 from sunlight; it cannot be obtained through
foods. In the body, vitamin D is responsible for maintaining
normal blood levels of calcium and phosphorus,
helping to build strong bones. Vitamin D may
also contribute to the overall health of the cardiovascular
system. Vitamin D works with other vitamins,
minerals and hormones to promote bone mineralization.
