Link Between Diabetes & Vitamin D Levels – What We Know

Vitamin D is a fat-soluble vitamin and plays a vital role in maintaining the health of bones, teeth, and joints and assisting immune system function. It is produced in the body when ultraviolet rays from sunlight strike the skin and trigger Vitamin D synthesis. In addition, vitamin D can be consumed through certain foods. The amount of Vitamin D needed on daily basis depends on your age.

How Are Vitamin D and Diabetes Connected?

There is growing evidence that vitamin D deficiency could be a contributing factor in the development of both type 1 and type 2 diabetes, and vitamin D treatment improves glucose tolerance (the ability to dispose of glucose loads) and insulin resistance (impaired response of the body to insulin).

Vitamin D is believed to help improve the body’s sensitivity to insulin – the hormone responsible for regulating blood sugar levels – and thus reduce the risk of insulin resistance, which is often a precursor to type 2 diabetes.

According to researchers at the Harvard School of Public Health (HSPH) – having adequate levels of vitamin D during young adulthood may reduce the risk of adult-onset type 1 diabetes by as much as 50%. In type 1 diabetes (insulin-dependent diabetes), the body’s immune system attacks and permanently disables the insulin-making cells in the pancreas.

It is not quite possible yet to correlate directly between Vitamin D levels and the occurrence of Diabetes. As the role of vitamin D in helping to regulate blood glucose remains poorly understood, vitamin D status appears to play a role in the development and treatment of diabetes.

It is also possible that persons who have sufficient vitamin D levels are more likely to participate in outdoor physical activity, which would also decrease their risk of type 2 diabetes.

A study published in 2018, tied higher vitamin D levels to lower diabetes risk. The researchers who performed the study over 12 years found that compared with people whose blood levels of vitamin D were below 30 nanograms per millilitre (ng/ml), people with vitamin D levels of 30 ng/ml or more had one-third the risk for developing diabetes, and those with levels 50 ng/ml or more had one-fifth the risk.

The only way to be sure of your vitamin D level is by requesting a 25-hydroxy Vitamin D, or 25-OH Vitamin D, blood test. Ideally, your vitamin D level should be & 30 ng/ml.
