A Deficiency of this vitamin can lead to an early death


A recent Australian study showed that a lack of vitamin D, also called “the sunshine vitamin,” is associated with an earlier death. So what percentage of people are deficient in this vital nutrient? And which foods contain it?

The researchers found that those with greater vitamin D deficiencies had a greater risk of death.

Vitamin D is not only good for bone health, but it helps maintain strong muscles as well.

Vitamin D is an essential nutrient for anyone, as it helps maintain good health and strengthens bones and muscles.

“Though severe vitamin D deficiency is rare in Australia, it can still affect certain demographics such as the elderly and those with pre-existing health conditions,” said study first author Josh Sutherland.

The level of vitamin D is measured by the levels of 25-hydroxyvitamin D, which can be found expressed in either Nanomol/L (nmol/L), ng/mL measurements.

What causes vitamin D deficiency

.There are several reasons why someone might not get enough vitamin D, including:

  • – Not getting enough sun exposure
  • – Inefficient production of vitamin D within the skin
  • – A deficiency of vitamin D in food.
  • – The breakdown of vitamin D in the body by other drugs
  • – The presence of genetic problems that prevent the action of the vitamin in the body.

Types of Vitamin D

Did you know that there are two types of vitamin D?
