What's the difference between 25(OH)D and 1,25(OH)2D when it comes to the VDR?

Chris Masterjohn, PhD is the Founder and Scientific Director of the mitochondrial test mito.me. Short answer: 25(OH)D is 1000 times weaker at activating the VDR than 1,25(OH)D, but 1000 times more abundant. This is why I advocate measuring both, and ultimately believe we need to create a calculated index of “biological vitamin D activity” from them.
