What is the function of the vitamin D receptor (VDR)? How does it interplay with the retinoid receptor (RXR)? What happens to your thyroid function when you supplement D3 and drive up your 1,25D levels? Can supplementing D3 drive the development of osteoporosis? Why does the half-life of 25D and 1,25D matter? Why do you never hear the word "heterodimerization" in vitamin D smurf talk? What is a dimer?
Vitamin D researcher Jim Stephenson Jr shares his research and dot connections about hormone D supplementing and the effects that it has to cause imbalance in our body. He challenges listeners to dig deeper beyond two or three molecules and to realize the complexity of secosteroid hormone D.
We go down the list point-by-point of a popular pro vitamin D3 article written by researcher Danny Roddy with the goal of bringing clarity to the discussion. We cover oral versus topical administration of D3 and explore the question: how would a substrate lower one of the potentials that it can become?
