vitamin-D

Vitamin D is not only essential for healthy bones, but also very important in activating the immune system, preventing seasonal flu, enhancing cardiovascular health and reducing the risk of colorectal cancer.

A study conducted in nearly 50,000 men for 10 years found that men who were deficient in vitamin D were twice as likely to have a heart attack as men who had adequate levels of vitamin D (*). There is also an association between autism spectrum disorder and vitamin D insufficiency. A study of 109 children with autism spectrum disorder indicated that autism symptoms improved significantly after receiving four months of vitamin D3 supplementation (**).

Despite the crucial role of vitamin D to the body, almost 50% of the population worldwide are vitamin D deficiency (***).

Our body produces vitamin D when the skin is exposed to sunlight. We also get vitamin D through certain foods, but very few foods naturally have vitamin D.

There are certain groups of people at high risk of vitamin D deficiency:

  • People working indoors and having limited access to outdoor sunlight
  • People over age 50
  • People who are overweight or obese
  • People with celiac disease
  • People suffer from depression

Next time you have a blood test, remember to test your vitamin D levels to ensure you are in good health.
