The Importance of Vitamin D in Diabetes Prevention and Management

Published on: 07/04/2023

Diabetes is a chronic condition that affects millions of people worldwide, and its prevalence is increasing at an alarming rate. The condition can lead to a range of health complications, including heart disease, stroke, and nerve damage. 

While there is no cure for diabetes, there are ways to manage the condition and reduce the risk of developing it. One of these ways is through adequate levels of vitamin D, in addition to diet and exercise.

Let’s take a closer look at what vitamin D is and why is is important to those with diabetes.

What is Vitamin D

Vitamin D is a vital nutrient that is essential for bone health, immune function, and overall health. It is produced in the skin when exposed to sunlight, and it can also be obtained through diet or supplements. Recent studies have shown that vitamin D may also play a role in the prevention and management of diabetes.

Vitamin D and Diabetes

Diabetes is a condition that affects the body’s ability to produce or use insulin effectively. Insulin is a hormone that regulates blood sugar levels, and when the body does not produce or use insulin correctly, blood sugar levels can rise to dangerous levels. Vitamin D has been shown to improve insulin sensitivity, which means that the body can use insulin more effectively. This can help to regulate blood sugar levels and reduce the risk of developing diabetes.

In addition to improving insulin sensitivity, vitamin D also plays a role in inflammation and immune function. Chronic inflammation is a contributing factor in the development of diabetes, and vitamin D has been shown to reduce inflammation in the body. Vitamin D also helps to support a healthy immune system, which can help to prevent infections that can lead to diabetes complications.

Studies have shown that people with low levels of vitamin D are at an increased risk of developing diabetes (1-3). One study found that individuals with the highest levels of vitamin D had a 43% lower risk of developing type 2 diabetes compared to those with the lowest levels (1). Another study found that vitamin D supplementation in people with type 2 diabetes improved insulin sensitivity and glycemic control (2).

Who may need to supplement

While the role of vitamin D in prevention and management of diabetes is still being studied, there is evidence to suggest that adequate levels of vitamin D are important for overall health and well-being. As we get older, our need for vitamin D increases. We spend less time outside and our kidneys are not as good at converting it as they were in younger years. Those that may benefit from vitamin D supplements includes:

  • Older adults
  • Those living in northern climates
  • Those who do not go outside regularly

If your Vitamin D levels are low you may need a higher dose of supplement. For most adults a dose of 5,000 IU daily is an adequate dose. Check with your dietitian or doctor before starting or changing supplements.
