Vitamin D3

Benefits

Dr. Western A Price found healthy cultured consumed between 3000-6000 IU of vitamin D daily.  In our modern diet is it very difficult to eat foods containing this much Vitamin D, therefore supplementation is recommended for most people.  We can make Vitamin D as sunlight activates vitamin D3 from the cholesterol located in the skin. This is then converted in the liver and processed by the kidney to help maintain calcium balance in the body. As we age, our body’s ability to convert vitamin D in the skin declines.  However, in New Zealand we need to be in the sun between 10am and 2 pm in summer without sunscreen to be able to do this.

Vitamin D deficiency in New Zealand is commonplace, with over 90% of women tested by one of Hawkes Bay's top nutritionists, coming back as being deficient.

Recent Research

 

Vitamin D supplementation May Benefit Early Breast Cancer Patients Receiving Aromatase Inhibitors

Reference:    "Vitamin D deficiency and bone mineral density in postmenopausal women receiving aromatase inhibitors for early breast cancer," Nogues X, Tusquets I, et al, Maturitas, 2010 Apr 14; [Epub ahead of print]. (Address: Internal Medicine Department, URFOA-IMIM, RETICEF, Hospital del Mar, Autonomous University of Barcelona, Passeig Maritim 25-29, 08003 Barcelona, Spain).
Summary:     In a study involving 232 consecutive women with early breast cancer (EBC) receiving aromatase inhibitors, results indicate a high prevalence of vitamin D deficiency which significantly improved with vitamin D supplementation. At baseline, 88.1% of subjects showed 25-hydroxyvitamin D [25(OH)D] levels less than 30 ng/ml, and 21.2% showed severe deficiency (less than 10 ng/ml). Vitamin D deficient patients received supplementation with vitamin D (16,000 IU every 2 weeks). At 3-month end, patients in the vitamin D-supplemented group showed a 32.55 ng/ml mean increase in 25(OH)D levels. Thus, the authors of this study conclude, "Our study suggests a high prevalence of commonly unrecognized Vitamin D deficiency in women with EBC treated with AI, a known osteopenic agent. Our results support the need for a routine assessment of 25(OH)D levels and, when necessary, supplementation in these patients."

 

Higher Vitamin D Status May Reduce the Risk of Type 2 Diabetes

Reference:    "Predicted 25-hydroxyvitamin D score and incident type 2 diabetes in the Framingham Offspring Study," Liu E, Meigs JB, et al, Am J Clin Nutr, 2010 June; 91(6): 1627-33.

Summary:     In a study involving 1,972 Framingham Offspring Study subjects, out of which 133 type 2 diabetes mellitus cases were identified over an average 7 year follow-up, higher vitamin D status was found to be associated with a reduced risk of type 2 diabetes mellitus. Subjects in the highest tertile of vitamin D status were found to have a 40% lower incidence of type 2 diabetes after adjusting for various confounding factors (HR=0.60). The authors conclude, "Maintaining optimal 25(OH)D status may be a strategy to prevent the development of T2D."

Higher Vitamin D Levels May be Associated with a Reduced Risk of Pancreatic Cancer

Reference:    "Predicted vitamin D status and pancreatic cancer risk in two prospective cohort studies," Bao Y, Fuchs CS, et al, Br J Cancer, 2010; 102(9): 1422-7. (Address: Channing Laboratory, Department of Medicine, Brigham and Women's Hospital, Harvard Medical School, 181 Longwood Avenue, Boston, MA 02115, USA.

Summary:     In a prospective study involving 118,597 participants in the Nurses' Health Study and Health Professionals Follow-up Study, results indicate that higher vitamin D levels may be associated with a reduced risk of pancreatic cancer. During 20 years of follow-up, 575 incident cases of pancreatic cancer were recorded. After adjusting for confounders, 25-hydroxyvitamin D [25(OH)D] levels were inversely associated with risk of pancreatic cancer, where the highest quintile of 25(OH)D was associated with a 35% reduced risk of pancreatic cancer, compared with the lowest quintile. Thus, the authors of this study conclude, "Higher 25(OH)D score was associated with a lower risk of pancreatic cancer in these two prospective cohort studies."
