+ | ==== Are There Concerns About Over-supplementing with Vitamin D? ==== | ||
+ | |||
+ | There is a common misconception that vitamin D supplementation is safe at any reasonable level, or that if some is good, more may be better. | ||
+ | |||
+ | * It is clear that vitamin D intakes and serum 25(OH)D must be very high—perhaps 200-400 ng/mL—to cause the classic toxicity of marked hypercalcemia and kidney and liver damage. | ||
+ | * | ||
+ | * However, emerging observational data suggest that adverse outcomes may occur at much lower levels, such as in the 50-75 ng/mL range. These suspected adverse outcomes appear to include increases in all-cause mortality and increases in the rate of heart disease and some cancers. | ||
