Taking Vitamin D supplements daily does not prevent diabetes.

A study has found that consuming high doses of vitamin D over a long period of time has no substantial effect on lowering the risk of developing diabetes in healthy adults.

 

Vitamin D is known to reduce the incidence of diabetes by improving insulin resistance and aiding blood sugar control. According to a study published in the *American Journal of Clinical Nutrition*, individuals with low vitamin D levels had a higher risk of developing diabetes than those with higher levels. Research findings supporting this indicate that vitamin D supplementation improves insulin sensitivity in high-risk groups for diabetes.

 

Although some studies have proven its effectiveness, observational studies alone cannot establish a causal relationship between vitamin D supplementation and diabetes, and it is difficult to define the precise dosage required to produce the desired effect. Furthermore, controversy surrounding vitamin D supplementation continues as results from some clinical studies suggest that the effects have been exaggerated.

Amid ongoing controversy over whether vitamin D supplementation is effective in preventing diabetes, a research team at the University of Eastern Finland conducted a study to prove the effects of taking high doses of vitamin D over the long term.

 

The research team tracked 2,495 men aged 60 and older and 2,495 women aged 65 without glucose metabolism disorders for approximately five years. Participants were randomly assigned to groups receiving 40 μg (1600 IU) of vitamin D3 daily, 80 μg (3200 IU) of vitamin D3 daily, or a placebo. Using data from the National Health Registry, the research team collected information on the participants' lifestyles, nutrition, diseases, and risk factors, and collected and analyzed blood samples.

Diabetes developed in 105 people over a period of 5 years. The number of people who developed diabetes in each group was 31 in the 40μg daily vitamin D3 group, 36 in the 80μg daily vitamin D3 group, and 38 in the placebo group, with no statistically significant difference between the groups.

During the first two years, the effects of vitamin D on blood sugar, insulin levels, body mass index, and waist circumference were investigated, but no differences were found between the groups.

 

The research team analyzed that factors such as the study subjects and the limitations of high-dose vitamin D had an impact. 

 

The research team explained that while vitamin D may be effective for high-risk groups, such as those with pre-diabetes, its effects may not be well-represented in healthy individuals.

 

The research team said, “ Even though Vitamin D is effective in improving blood sugar, taking an excessive amount does not double the effect. "saying

 

"Since many other factors besides vitamin D, such as genetic factors, dietary habits, and exercise, influence the onset of diabetes, it may be difficult to expect sufficient preventive effects from vitamin D alone," he said.

Diabetes management involves dietary habits and

It seems prevention through exercise comes first.
