RDA for Vitamin D? At Least 5 Times Too Low

An organization that specializes in researching nutritional medicine,  www.Orthomolecular.org, reports that Vitamin D level recommendations by the government are way too low to prevent some basic health problems. The organization, made up of a number of MD’s, is one of the most credible sources for information on nutritional medicine.

Anxiety and depression can be affected by low Vitamin D levels.

They recommend White-Americans should consider taking at least 2000 IU/day.  African-Americans should consider taking at least 3000 IU/per day.  The organization bases this on a review of a large number of existing scientific studies.    During pregnancy and lactation, they recommend women should be taking about 6000 IU/day, based on a recent study by Dr. Bruce Hollis at the Medical University of South Carolina.

[Many MD’s and Naturopath’s we talk suggest that 4000 to 5000 iu Vitamin D is a good amount to take for basic health for adults.]

The current government recommendation is only 400 iu per day and was based on old studies to prevent rickets – not to achieve good health.

Vitamin D helps both to prevent and to treat chronic diseases including many types of cancer, heart disease, stroke, and diabetes. It is also effective against both bacteria,  viral infections, and autoimmune diseases.  The autoimmune diseases include asthma, multiple sclerosis, and perhaps rheumatoid arthritis.

Pregnant women can also be negatively affected by low serum D levels. There is significantly increased risk of a C-section delivery,  and preeclampsia is also linked to low serum levels of D.

There are few adverse effects of vitamin D. Whole-body exposure to the sun can create 10,000 IU/day in a short time. People have taken 20,000-50,000 IU/day for several months with no adverse effects.  However, those with certain diseases such as adenoma of the parathyroid gland, granulomatous diseases, lymphoma, sarcoidosis, and tuberculosis, should limit their vitamin D intake.
