Is Vitamin D Supplementation Safe?

Vitamin D isn’t a vitamin, it’s part of the steroid hormone axis alongside cortisol, estrogen, testosterone, and DHEA. This distinction is important because when you supplement with a steroid hormone, you don’t simply raise a level, you introduce a signal into a tightly controlled feedback system that’s designed to regulate itself.
