We hear about Vitamin D all around us from commercials, to media, to the internet. But do you really know what Vitmain D is and how it can be beneficial?
In the medical community there is a push to better understand both the risks of low Vitamin D as well as the vast effect of this Vitamin on health.
Vitamin D is a fat soluble Vitamin that helps with intestinal absorption of several other compounds including: Iron, Calcium, Magnesium, Zinc and more. There are several different types of this Vitamin, for humans, the most important is D3 or Cholecalciferol. Vitamin D2 – Ergocalciferol is also important.
Both types can be ingested and from supplements. But very few foods contain Vitamin D. Synthesis from Cholesterol happens in the skin from sun exposure, UVB radiation.
This is the catch 22 problem though – no official recommendation will be given for sun treatment due to the fact that sun can be a leading cause of cancer of the skin. Therefore, many intake guides only recommend consumption of Vitamin D.
Currently low Vitamin D can cause some serious medical issues such as Osteomalacia and/or Rickets. This is actually the same condition, Rickets is found in children.
Donald Hensrud, MD, medical director of the Mayo Clinic Healthy Living Program said, ” 20-50 percent of adults have some form of low vitamin D values.”
InterMoutain Medical Center Study
Recently, from Intermountain Medical Center – researchers suggest that the risk of Diabetes, Heart Attack (MI), heart failure, High Blood Pressure, Stroke and other cardiac events can be predicted by reviewing Vitamin D total and Vitamin D bioavailable.
Bioavailable vitamin D is vitamin D that has been absorbed but has yet to attached to certain proteins.
Dr. Heidi May was the lead researcher and she presented some findings in Chicago. She noted and followed approximately 4,200 adults between the ages of 52 – 76.
25% had Diabetes and 70% had Cardiac Heart Disease.
Dr. May said, “Our study found that low levels of both total vitamin D and bioavailable vitamin D appear to be associated with poor cardiovascular outcomes.”
Their study tested Vitamin D levels and the metabolism of Vitamin D. Only 10-15 percent of Vitamin D total is available to act on “target cells”.
The study did test some of the different types of vitamin D, but found that measuring total vitamin D and bioavailable vitamin D were the most accurate.
“This study is the first research that evaluates the association of vitamin D metabolites with cardiovascular events And evaluating usable vitamin D could mean the difference on the amount of vitamin D prescribed, if it’s prescribed at all,” continued Dr. May.
Intermountain Medical Center is the flagship facility for the Intermountain Healthcare system, which is based in Salt Lake City.

Additional Research and Studies
1.) Prostate Cancer
Dr. Adam Murphy said, “Vitamin D deficiency may predict aggressive prostate cancer. Men with dark skin, low vitamin D intake or low sun exposure should be tested for vitamin D deficiency when they are diagnosed with an elevated PSA or prostate cancer. Then, a deficiency should be corrected with supplements.“ Dr. Murphy is a urologist, assistant professor of urology at Northwestern University Feinberg School of Medicine, and the lead investigator on this study.
2.) Multiple Sclerosis
According to research, taking a high dose of vitamin D may be an easy and less expensive way to treat people with Multiple Sclerosis (MS), an autoimmune disorder that affects the brain and spinal chord.
Additional researchers recently conducted a longitudinal study of patients in order to determine whether vitamin D supplementation modifies the response to HIV infection and possibly Tuberculosis noted lead researcher Nina Jablonski, PhD.

Vitamin D supplements
- Can be taken in the form of a multivitamin
- The Food and Nutrition Board established guideline – 400 IU (International units) per day.
- Institute of Medicine recommends – 600 IU
- Vitamin D council recommends – 1,000 IU for children, 5,000 IU for pregnant and adults, 10,000 IU limit for certain Deficiencies.
- Osteoporosis International recommends – 2,000 – 3,000
