Getting enough of this vitamin is the most important thing you can do to protect yourself against neuropathy, according to a new study in Nutrition and Health.
Because vitamin D calms inflammation, produces substances that keep nerve cells healthy, and repairs the myelin coating around them, researchers wanted to know if low levels could be playing a bigger role in diabetic complications.
At a major hospital in southern India, scientists reviewed records of 1,439 adults with type 2 diabetes admitted between 2017 and 2022 who had their vitamin D levels checked.
They split the group into:
-
● 873 people with at least one diabetic complication
● 566 people with no complications
Findings:
-
● Vitamin D deficiency = 4x higher neuropathy risk
● Kidney problems risk rose more than 5x
● Eye damage risk increased 2.5x
● Heart disease risk more than doubled
● Diabetic foot problems nearly tripled
Even in sun-rich India, vitamin D deficiency was especially common in women, city dwellers, and indoor workers — proving that lifestyle matters more than geography.
Protect yourself: Get about 20 minutes of daily sunlight on your arms or legs, eat vitamin D-rich foods (salmon, mackerel, sardines, eggs, mushrooms, fortified milk/cereal), or take a supplement.
