Vitamin D: Diabetes Defense or Hype?
21 Mar
Summary
- Vitamin D may lower type 2 diabetes risk in non-obese individuals.
- Studies show mixed results on vitamin D's effect on blood sugar.
- Government advises vitamin D supplements during autumn and winter.
Emerging research suggests that vitamin D supplements could play a role in reducing the risk of type 2 diabetes, especially for non-obese individuals. Professor Tim Spector noted that recent studies indicate a potential benefit, though the exact mechanisms remain unclear. One meta-analysis found a significant reduction in type 2 diabetes risk among pre-diabetic participants taking vitamin D.
However, the scientific community acknowledges discrepancies in findings. Some reviews indicate no significant improvement in blood sugar levels for existing type 2 diabetes patients. Experts emphasize the need for further research to establish optimal dosing and long-term effects. The UK government advises daily vitamin D intake during autumn and winter to maintain bone and muscle health.
