Vitamin DIn the past years, vitamins C and E continue to be the top favourites of many supplement lovers. On the contrary, vitamin D does not get the attention it rightly deserves. In fact, recent studies have suggested that up to 50% of adults and children worldwide are vitamin D deficient. This is where supplementation comes in.

Did you know vitamin D is as crucial as vitamins C and E? Yes, vitamin D is helpful for optimal health too. Vitamin D is not a regular vitamin. It's actually a steroid hormone that you get primarily from sun exposure, diet or supplementation.

But if you live in UK where cold months are longer than warm months, odds are that you don’t get enough vitamin D. According to experts, it is estimated that ample sun exposure on bare skin for 5-10 minutes weekly allows the body to generate sufficient vitamin D, but it has a half-life of only 14 days; this means that stores can run low, especially during the cold months.

Here are the reasons to ensure that you are getting enough vitamin D:

Bone Health

Vitamin D plays a role in keeping your bones healthy. Exposure to sunlight leads to the production of vitamin D3 in the skin. Vitamin D3 will be metabolized by the liver and kidney into 1, 25-dihydroxy vitamin D. Its role is to ensure that there is enough concentration of calcium and selenium necessary for cellular functions and mineralization of the bone.

Cardiovascular Health

Vitamin D can help you keep your heart healthy and prevent various cardiovascular diseases, such as hypertension, atherosclerosis and heart attack. A study found that participants who were vitamin D deficient were 50 percent more at risk of suffering a heart attack. What’s worse, a vitamin D deficient person who will suffer from a heart attack has a 100 percent chance of dying.

Weight Loss

For someone who is overweight or obese, increased vitamin D intake may be necessary to lose weight effectively.

Every cell in your body needs vitamin D to function properly including fat cells. Your body has special receptors for vitamin D which signal whether to burn or store fat. Moreover, you need vitamin D for better calcium absorption, which is also necessary for weight loss. Calcium deficiency can result to the five times increased production of fatty acid synthase, an enzyme that turns calories into fat.
