Tufts researchers found AC or CC vitamin D receptor variants in more than 2,000 US adults with prediabetes were linked to a 19% lower diabetes risk on 4,000 IU daily.
The secondary analysis, published in JAMA Network Open, found no benefit for the AA variant and suggested vitamin D may act through receptors in the pancreas, which produces insulin.
Researchers said the finding needs replication and is too early for general recommendations, warning high doses can harm older adults and may raise fall risk despite vitamin D's low cost.

This high-dose vitamin D strategy has risks. Is the potential benefit for some worth the danger for others?

Is 'precision nutrition' a real breakthrough or a distraction from proven diabetes prevention like diet and exercise?
