Has science proven that the minimal acceptable blood level of vitamin D, in the form of 25(OH)D, is above 50 ng/mL (125 nmol/L)? No. If you’ve been trying to maintain your levels this high because you thought this was the case, I’m sorry to break the news. There is, on the contrary, good evidence that 25(OH)D levels should be at least 30-35 ng/mL (75-88 nmol/L). Much higher levels may be better, or they could start causing harm, especially in the absence of adequate vitamins A and K2. Once we leave the land of 30-35 ng/mL, however, we enter the land of speculation.
