Vitamin D is known as the sunshine vitamin because the body makes vitamin D
when the skin is exposed to sunlight. Scientists learned about the importance of
this vitamin when it was discovered in the early 1900s by Dr. Elmer McCollum,
Dr. Edward Mellanby, and others during their research on rickets. Rickets is a
debilitating bone disease that disabled many children. Over the past century, the
crucial role of vitamin D in bone health has been well established. Results from
a rigorous review of 167 studies showed that vitamin D at a minimum of 700 to
1,000 IU daily combined with calcium was associated with better bone mineral
density, reduced fracture risk, and reduced risk of falls.
Interestingly, in the past few decades, scientists have linked numerous non-bone
modern-day health concerns to low vitamin D levels. For example, research has
discovered a correlation between weakened immune systems and low vitamin D
levels in the blood, suggesting a possible need for supplementation.
2 To help
maintain a healthy immune system, talk to your healthcare professional about
having your vitamin D level evaluated to ensure your vitamin D levels are
adequate. Vitamin D supplementation may be necessary, particularly during
the winter months, when sunlight exposure is significantly decreased.
Vitamin D is a unique micronutrient, acting as a hormone once it is in the body.
Vitamin D regulates over 500 genes and has been discovered in most tissues of
3 Vitamin D has been proven to be a key ingredient for overall well-being.
Since few foods naturally contain vitamin D, many people spend most of their
time indoors, and fortified foods contain minimal amounts of this nutrient, vitamin
D supplementation is recommended for maintaining optimal health.
