“Vitamin D has been oversold.”
You have most definitely heard about all the studies that linked low levels of vitamin D with higher risks of wide-ranging problems like cancer, heart attacks, infections, Alzheimer’s disease, autoimmune conditions, depression, and even obesity.
When Dr. Rosen hears about these reports from his friends, he explains how the studies didn’t mention anything about cause and effect. “These associations might be really misleading” he explained. He also explained that without additional trials, we won’t have a good sense of how vitamin D supplements might help.
The only exception is that vitamin D intake has been proven to promote strong bones. You might need vitamin D to absorb calcium, so that’s basically why you see the two of them packed together.
