Vitamin D deficiency is now recognized as a pandemic. The major cause
of vitamin D deficiency is the lack of appreciation that sun exposure
in moderation is the major source of vitamin D for most
humans..........

And low levels of vitamin d have been linked to multiple health
problems..... The vitamin D epidemic and its health consequences.

Vitamin D deficiency is now recognized as an epidemic in the United
States. The major source of vitamin D for both children and adults is
from sensible sun exposure. In the absence of sun exposure 1000 IU of
cholecalciferol is required daily for both children and adults.
Vitamin D deficiency causes poor mineralization of the collagen matrix
in young children's bones leading to growth retardation and bone
deformities known as rickets. In adults, vitamin D deficiency induces
secondary hyperparathyroidism, which causes a loss of matrix and
minerals, thus increasing the risk of osteoporosis and fractures. In
addition, the poor mineralization of newly laid down bone matrix in
adult bone results in the painful bone disease of osteomalacia.
Vitamin D deficiency causes muscle weakness, increasing the risk of
falling and fractures. Vitamin D deficiency also has other serious
consequences on overall health and well-being. There is mounting
scientific evidence that implicates vitamin D deficiency with an
increased risk of type I diabetes, multiple sclerosis, rheumatoid
arthritis, hypertension, cardiovascular heart disease, and many common
deadly cancers. Vigilance of one's vitamin D status by the yearly
measurement of 25-hydroxyvitamin D should be part of an annual
physical examination.
