Almost everyone now is aware of the beneficial effects that Vitamin D has on our bodies. Most people have heard the studies indicating that vitamin D helps to prevent cancer, but there is also research indicating that low level of vitamin D have been found in patients suffering from Multiple Sclerosis, Parkinson’s disease, rheumatoid arthritis, thyroiditis, Chron’s disease, osteoporosis, and some behavioral and learning disorders.
Vitamin D is well known for its role in assisting with the absorption of calcium, but it has been shown to have a wide range of important roles in the body, including:
- Playing a role in inflammation and infection
- Supporting the production of estrogen and testosterone in men and women, aiding with PMS, menopause, and infertility
- Playing a vital role in brain development both pre and post natally
- Supporting the production of important brain chemicals, including dopamine and adrenalin
- Helping to normalize blood sugar
- Assisting in normalizing weight by affecting how/when fat gets stored
- Deficiencies in vitamin D have been mistaken for Chronic Fatigue Syndrome, Fibromyalgia, and peripheral neuropathy
Blood test measurements have shown that many people have unexpectedly low levels of vitamin D, putting them at a higher risk for many health challenges. Vitamin D researchers emphasize that the vitamin D requirements of people living in northern latitudes is much greater than what is being achieved.
The Canadian Cancer Society agrees, and recommends that adults living in Canada should consider taking Vitamin D supplementation of 1,000 international units (IU) a day during the fall and winter and adults at higher risk of having lower Vitamin D levels should consider taking Vitamin D supplementation of 1,000 IU/day all year round.
Dr. Reinhold Vieth, one of the leading authorities on Vitamin D research in the world, along with many other vitamin D researchers, believe that these recommendations may be too low to provide the body with optimal blood concentrations of 100-150 nmol/L (40-60 ng/mL) of vitamin D. His recommendation is 2000 IU of Vitamin D daily.
Since the absorbability and utilization of vitamin D is unique for each individual, it is recommended that you have your vitamin D levels tested by a medical professional using the Calcidiol or 25-hyrdoxyvitamin D test to determine how much vitamin D you may need.
