Vitamin D, also known as the sunshine vitamin, can be
produced in the body through sun exposure or consumed in food or supplements.
However, it is estimated that vitamin D produced by the sun
has a half-life of only two weeks, meaning that stores can easily run low, especially
in rain season. Recent studies have suggested that up to 50% of adults
and children worldwide are vitamin D deficient.
Adequate vitamin D intake is important for the
regulation of calcium and phosphorus absorption, maintenance of healthy bones
and teeth, and is suggested to supply a protective effect in connection with a
number of today’s health issues. For example, if your body does not get enough
vitamin D, you are at risk of developing bone abnormalities such as soft bones
(osteomalacia) or fragile bones (osteoporosis). Vitamin D has multiple roles in
the body, helping to:
- Maintain the health of bones and teeth
- Support the health of the immune system, brain and nervous system
- Regulate insulin levels and support healthy blood sugar levels
- Support lung function and cardiovascular health
What other benefits might vitamin D
offer?
According to a study presented at the American
College of Cardiology 65th Annual Scientific Session & Expo in Chicago, IL,
daily supplementation with vitamin D may improve heart function. According to
Dr. Klaus Witte of the University of Leeds School of Medicine in the UK, and
his colleagues, a daily vitamin D supplement could be beneficial for patients
with heart health issues.
Research has also shown that vitamin D may play
an important role in regulating mood and supporting a sense of well-being. In
some studies, scientists found that people with depression who received vitamin
D supplements noticed an improvement in their symptoms.
