Vitamin D has always been seen as the vitamin that keeps our bones strong. Nevertheless, studies reveal that this sunshine vitamin may also affect how your body controls blood sugar. That’s important, as diabetes cases are rising every year and vitamin D deficiency is extremely common.
Almost 9 out of 10 Indians are vitamin D deficient, and many don’t even realise it, reveals Dr Farah Ingale, Director, Internal Medicine & Diabetologist, Fortis Hiranandani Hospital, Navi Mumbai
She adds that over 101 million Indians are living with diabetes, making it vital to understand how even simple deficiencies might worsen the problem.
Vitamin D, which we mainly get from sunlight and certain non-vegetarian foods, plays more than one role. Besides supporting bones and immunity, it may influence inflammation in the liver and pancreas, organs that manage insulin production. “Healthy vitamin D levels help increase insulin sensitivity,” says Dr Ingale. “Low levels, on the other hand, make it harder for the body to use insulin well, which may cause blood glucose to rise.”
Dr Ingale shares how vitamin D may influence diabetes:
Supports insulin sensitivity: Sufficient vitamin D, helps the body to respond better to insulin. This improves blood sugar control.
Reduces inflammation: inflammation in the liver and pancreas, weak insulin function, vitamin D may help reduce this inflammation.
Linked with metabolic conditions: Studies reveal associations between low vitamin D and type 2 diabetes, gestational, diabetes, and other metabolic disorders.

Deficiency worsens health markers: a study from Romania conducted on 160 patients with type 2 diabetes found that nearly 63 percent were vitamin D deficient, and those with lower levels had poor blood sugar control, higher weight, kidney issues, and some other complications.
Common among people with other diseases: Deficiency was especially seen in those with heart disease, hypertension, neuropathy, and even dementia
Improved absorption through modern supplements: Vitamin D supplements are available for people who struggle to get enough from sunlight or food, and some newer formulations aim to improve absorption. Consult your doctor.
While vitamin D supplements are not a treatment for diabetes, studies show that low levels can worsen blood sugar problems and contribute to metabolic disorders. Dr Ingale adds, “In a country like India, where sunlight is abundant but deficiency is widespread, awareness is key. “Sensible sun exposure, a balanced diet and regular health checks can go a long way,” she says.
