In recent years a lot of attention has been given to Vitamin D. Doctors have known for years that it is necessary for strong bones. Vitamin D is required for the body to assimilate calcium into our bones. The lack of Vitamin D can cause weak bones called Rickets. Low levels of Vitamin D have also been found to be associated with cardiovascular disease, cognitive impairment in adults, asthma, cancer, and a weakened immune response.

There are various reasons why someone may become Vitamin D deficient. Because the body requires exposure of the skin to activate Vitamin D, geography often plays a role in Vitamin D deficiency. People living in Northern latitudes are exposed to less sunlight and are at a greater risk. Having dark skin or using sunscreens can diminish Vitamin D levels, and digestive issues such as Crohn’s Disease can prevent the absorption of Vitamin D from food sources. Being obese is another factor because Vitamin D, being a fat soluble vitamin, can get trapped in our own fat cells where the body doesn’t have access to it.

The following excerpt was taken from a recent article in Natural News about Vitamin D:

(NaturalNews) A new study published this month finds that the hormonally active form of vitamin D, Calcitriol 1,25-dihydroxyvitamin D(3), inhibits the growth of many kinds of cancerous cells, including breast cancer, indicating that vitamin D3 can be useful in treating and even preventing a variety of cancers. Authors of the study said that caner cell growth is inhibited by “anticancer actions including cell cycle arrest, promotion of apoptosis and inhibition of invasion, metastasis, and angiogenesis.” Vitamin D’s anti-inflammatory properties and interference with estrogen synthesis further explains its anti-tumor properties.

If you are concerned about your Vitamin D level it can be tested with a simple blood test. A healthy level is considered to be at least 50 ng/mL.  Some sources disagree as to what is considered a healthy range, so it is valuable to get the exact number rather than just a report of normal. Levels below 50 ng/mL may require supplementation and/or increasing your exposure to sunlight.

Recommended Daily Allowance of Vitamin D is between 600-1000 IU/day. If you are deficient you can use a supplement, increase your intake of Vitamin D containing foods, and increase your exposure to sunlight. If you increase your exposure to sunlight do some research first so that you do it safely without getting burned. If you choose to supplement, seek out a high quality whole food supplement. As far as food goes, the best sources are from fish like sardines and salmon. Other foods like milk are fortified with Vitamin D.
