Vitamin D is a fat soluble vitamin best known for its role in bone health. Bone cells are continually breaking down and reforming, and without enough vitamin D, bones can become thin and brittle.

There are few foods that actually contain vitamin D.... Some fish and fish oils are naturally rich in vitamin d, and almost all of the milk supplied in the united states is fortified with vitamin D, as well as some cereals, juices, and yogurts. The good news is that vitamin D can be made in our skin when we are exposed to direct sunlight.

Many people don't get enough vitamin d every day. In fact, new recommendations have doubled the requirement for both children and adults. Most adults need at least 800 units every day.

So, are you getting enough vitamin D? It depends a lot on your age, where you live, and your use of sunscreen. Plus, if you're a senior, or have darker skin, production of vitamin d is also reduced.

My bottom line? Vitamin D is crucial for bone health and maintenance. If you think you're not getting enough, try adding more vitamin-d enriched food in your diet and increase your daily sun exposure. Consider a multivitamin or calcium supplement containing 100% of your daily vitamin D requirement.
