I just ran across an interesting study that, through statistical analysis, comes to the conclusion that the incidence of several types of cancers are lower when people have higher vitamin D blood levels. Their recommendation is for people to maintain vitamin D levels between 55ng/ml and 90ng/ml. These levels are between the standard mainstream medicine reference ranges of above 32ng/ml being optimal and above 100ng/ml being toxic.
These researchers are recommending vitamin D intakes between 2,000 and 10,000 IU per day. Current recommendations are 400-600 IU per day.
Vitamin D levels are accurately assessed with a test called 25-OH Vitamin D. If taking high doses of vitamin D, please have your vitamin D levels checked by your physician after 3 months of supplementation to ensure your safety.
Vitamin D3 5,000 IU
If you are deficient in vitamin D, supplementation will likely improve bone health, blood pressure, and possibly mood and immune function.
Here is the highest qualtiy and most affordable Vitamin D supplement I have found; tested for identity, potency, purity, and label claim to expiration date. Taking one capsule every third day ensures a daily dose below the Institute of Medicine’s conservative upper intake limit of 2,000 IU per day. At this dose, one bottle lasts about 9 months!
Be Well,
Richard
