Diabetes and Vitamin D
The analysis of more than 900 individuals from southern California found that having plasma levels of 25-hydroxyvitamin D (25[OH]D) greater than 75nmol/L was associated with a significant and substantial reduction in later diabetes risk.
The research, also showed that every 10nmol/L increase in 25(OH)D levels above 75nmol/L was associated with a 36% reduction in diabetes risk.
The desirable plasma target for 25(OH)D should be no less than 40 ng/mL (100 nmol/L).
