Researchers have recently found evidence that people living in Northern countries may be at a higher risk for Vitamin D deficiency. In northern countries such as Canada, the low level of light during the winter months may lead to Vitamin D deficiencies among the population. The majority of Vitamin D within our bodies is produced by sunlight (UVB rays) hitting the skin.

A recent research study conducted in Great Britain has indicated that 87% of the population around 45 years of age has a Vitamin D deficiency during the winter months. This is a staggering statistic. This deficiency can have serious consequences if it is not corrected. With a Vitamin D deficiency you are at more of a risk to develop certain types of cancers. This deficiency has also been linked to increased numbers of heart disease cases in Northern regions compared to regions closer to the equator.

So now you may be wondering, “How can I correct a Vitamin D deficiency?” Some people may substitute real UVB rays with herbal Vitamin D supplements. This works, but it is not always the best answer. The best way for your body to correct a Vitamin D deficiency is to supply it with the light it needs. Natural production is always the best correction method. An easy way to start correcting this deficiency is through the use of a tanning bed such as those used by Sunday’s Blue Box Tanning Resorts. This will supply the UVB rays which will help to increase your daily intake of Vitamin D and defend against potentially life-threatening diseases.

A new study indicates that at least 2,000 International Units (IU) of vitamin D3 -- which is currently considered the upper limit of intake -- are needed to ensure adequate blood levels of the vitamin for post-menopausal African-American women.

Over 200 women took part in this three-year, double-blind, placebo-controlled study, which adds to a growing body of evidence suggesting that there is an urgent need to review current recommended daily intake levels of the vitamin.

Vitamin D3 is produced in the skin during exposure to sunlight. However, increased skin pigmentation reduces the effect of UVB radiation, meaning darker-skinned people are more at risk of vitamin D deficiency.

As much as 4000 IU per day may be required for individuals who are already deficient in the vitamin.
