Vitamin D is rapidly becoming one of the most studied vitamins of our time. These studies have indicated that vitamin D is closely linked with several aspects of human health and survival. A new meta-analysis (collective review and analysis of previous studies) published in the European Journal of Clinical Nutrition (July 2011), reported finding a clear correlation between vitamin D intake of greater than 500 IU per day and a 13% reduced risk for developing type-2 diabetes. It was also noted that those individuals with the highest blood levels of vitamin D (>25 ng/dl) had a 43% lower risk of developing type-2 diabetes than
those individuals with the lowest blood levels (<14 ng/ml). This research review shows that vitamin D may play a role in the development and progression of type 2 diabetes; however, more high quality studies will be needed to find how and to what extent it may be used in the course of this health-related condition.

Research has proven there is a clear link between vitamin D blood levels and several health related conditions. Unfortunately this research has failed to discover a clear understanding of what is or isn’t the optimal level of vitamin D necessary to achieve and retain good health. A recent study published in the Journal of Clinical Endocrinology & Metabolism (December 2010), measured plasma levels of vitamin D and assessed frailty status in 4551 elderly women approximately 69 years of age. Results of testing showed vitamin D levels between 20 ng/ml – 30 ng/ml appeared to provide optimal protection against the development of frailty. Levels below or above this range were associated with an increased risk for frailty, with the lowest levels offering the greatest risk. Read More
Research has proven there is a clear link between vitamin D blood levels and bone mineral density (BMD). In many people, but especially in the elderly, vitamin D deficiency is common. In the elderly this deficiency often occurs due to reduced exposure to sunlight, as well as a reduced ability to synthesize vitamin D in the skin. Vitamin D is necessary for the intestinal absorption of calcium. When levels are low, less calcium enters the body and is therefore unavailable for bone mineralization and support. This overall depletion leads to reduced bone structure and strength, which is often more prevalent in older women. A recent study published in Osteoporosis International (March 2010), reported a positive increase in BMD in postmenopausal women after daily supplementation with vitamin D and calcium. Read More
Research has shown that lower blood levels of vitamin D have been associated with the increased occurrence of elderly health issues. A new study in the Journal of Clinical Endocrinology & Metabolism (May 2010), followed the vitamin D levels of 531 women and 423 men, over 65 years of age, for a period of 6 years. Participants’ depressive symptoms were assessed (using the Center for Epidemiological Studies-Depression Scale-CES-D). Those exhibiting lower blood levels of vitamin D (< 50 nmol/liter) scored significantly higher on the depression scale. The association between blood vitamin D levels and depression was also found to be more observable in women than men. Previous studies have supported the need for vitamin D for the physical health of the elderly. Read More

Scientists from the Department of International Health, Immunology and Microbiology have discovered that vitamin D is crucial to activating our immune defense. When there are insufficient levels of vitamin D circulating in the body, T-cells, the killer cells of our immune system, do not properly react to fight off serious infection. The first stage in the activation of a T-cell requires vitamin D. When a T-cell comes across a foreign pathogen, an immediate biochemical response extends a signal known as a vitamin D receptor, which is in search for vitamin D. This means that the T-cell must have access to vitamin D or activation of the cell will cease. Without proper mobilization of T-cells our body can not fight off infections. Read More
Numerous studies have shown that lower levels of vitamin D can be associated with the increased occurrences of health issues and premature mortality in the elderly. A new study published in Clinical Endocrinology (November 2009), followed the vitamin D levels of 614 men and women, average age of 70 years, over a period of 6 years. Those exhibiting the lowest blood levels of vitamin D were found to have 2-4 times the increased risk for all-cause mortality and cardiovascular mortality. This report helps to support the need for vitamin D supplementation with regards to reducing mortality and cardiovascular risks.

New research indicates that at least one in five children ages 1 to 11 are not getting enough vitamin D. Even more shocking, nearly 90% of African American children and 80% of Hispanic children may be deficient in this important vitamin.
Vitamin D has been shown to play an important role in bone health, heart health, immune health and much more! It can be obtained in a number of ways including dietary intake of foods such as milk and fatty fish, exposure to sunlight and dietary supplementation.

According to the latest update from the Harvard Medical School, vitamin D supplements are the best way to deliver a person’s vitamin D requirements. Foods such as fish or eggs contain vitamin D, but industry leaders strongly urge it’s not enough and while you can also get it through sunlight, it’s much easier to take a supplement which supplies adequate amounts.

Personally, I am so excited that it is staying lighter outside longer. A couple of months ago, the sun had just come up by the time I got to work and it had already set when I left. I was getting virtually no time in the sun. Now, even if I leave work at 6pm, there is still some daylight! I’m looking forward to turning the clocks ahead and getting even more sunlight!
Since people will probably be getting more sunlight as we have more daylight hours, I wanted to clear up a few things about sun exposure and vitamin D. Most of us know that vitamin D synthesis in our bodies is activated by sunlight on our skin. Read More
