Latest research has found a link between low levels of the fat-soluble vitamin and premature death, Medical News Today reported.
Researchers found that participants with lower levels of
25-hydroxyvitamin D— the main form of vitamin D found in human blood—
were twice as likely to have a premature death, compared to those with
higher blood levels of 25-hydroxyvitamin D.
Furthermore, researchers found that approximately half of the
participants who were at risk for early death had a vitamin D blood
level of 30 ng/ml. An estimated two-thirds of the U.S. population has a
blood vitamin D level below 30 ng/ml
The National Institutes of Health recommends children and adults ages 1
to 70 should consume 600 IU of vitamin D per day. But researchers
believe this amount should be increased. “This study should give the medical community and public substantial
reassurance that vitamin D is safe when used in appropriate doses up to
4,000 International Units (IU) per day,” said Heather Hofflich, a
professor in the UC San Diego School of Medicine’s Department of
Hofflich advised patients to have their 25-hydroxyvitamin D blood
levels checked annually and to consult their doctor before changing
their vitamin D intake.
Vitamin D helps the body regulate absorption of calcium and
phosphorus in the bones, aids cell communication and strengthens the
immune system. Vitamin D deficiency has long been associated with poor
bone health, but in the past few years research has linked deficiencies
in the vitamin to brain damage and increased preeclampsia risk for
pregnant women. Other studies have suggested a lack of clear evidence
for vitamin D’s health benefits.
