New RCT: Vitamin D helps lower blood pressure in people with type 2 diabetes

Posted on: March 28, 2014   by  Jeff Nicklas


A new trial published in the Journal of Nephropathology has found that vitamin D supplementation helps lower blood pressure in type 2 diabetes.

High blood pressure is very common in people with type 2 diabetes. Two-thirds of people with type 2 diabetes have high blood pressure or report taking medication to help lower blood pressure.

In type 2 diabetes, the body has a difficult time producing enough insulin or using the insulin that is produced from beta-cells in the pancreas. Insulin helps convert sugar and starches into glucose, which insulin then helps the body to store and use for energy. When insulin doesn’t properly store or use glucose, it begins to build up in the blood stream. Any sort of build-up in the blood stream makes the heart have to work harder to move blood throughout the body, which increases blood pressure.

    Jeff, the graphic here was so captivating to me, it got me thinking about vitamin D3 in the leaves of plants (my mind wanders due to increasing age 😉 )

    Anyway–here is what I discovered about vitamin D in plants (very cool stuff indeed):


    “Vitamin D deficiency is a problem in populations with limited sun exposure where a dietary intake of vitamin D becomes essential. However, dietary recommendations for vitamin D are difficult to meet because few food items naturally contain vitamin D and it would, therefore, be valuable to increase the food sources of vitamin D in the human diet or to optimize the content by bio-fortification. Traditionally, only animal products have been considered a source of vitamin D3, but today we know that vitamin D3 and its metabolites are formed in certain plants. Accordingly, fruits and vegetables have the potential to serve as a source of vitamin D. Especially, the Solanaceae family contains high amounts of vitamin D3, which is of special interest considering the importance of this family in human nutrition. The Solanaceae family includes important vegetables such as potato, tomato and pepper all of which have been found to contain vitamin D3. Our current knowledge is limited to the content in leaves, but future investigation will elucidate if also the edible portions contain vitamin D3.”
