The facts of Vitamin D

Our bodies manufacture Vitamin D from sunlight, and it's found in some foods – like Vitamin D fortified milk, ready-to-eat cereals, egg yolk and Swiss cheese. According to the National Institutes of Health (NIH), Vitamin D is essential for efficient calcium absorption – without it, bones can become thin and brittle.

Vitamin D also helps muscle cells mature and function, and it keeps them active and strong enough to support your body. Lack of Vitamin D can make your muscles weak, which is why the typical symptoms of Vitamin D deficiency are aching bones and muscle discomfort.

According to the NIH, National Institutes of Health, it can be difficult to obtain enough Vitamin D from natural food sources and sunlight. That's because many of us spend a considerable amount of time indoors or wear sunscreen whenever we're in the sun – and there simply isn't enough Vitamin D in many of our diets.

People who are at risk of Vitamin D deficiency include adults over 50, anyone who spends most of their time indoors, people who wear sunscreen (SPF 8 or greater) every time they go outside, anyone who is lactose intolerant, and African Americans and others with darker skin.

To make sure you can get the Vitamin D you need, Os-Cal variants offer you two levels of Vitamin D to choose from.
