Tag: Hormonal activation

Did you know vitamin D isn't active upon entering your body from sun or food? It is a pro-hormone that requires a complex, multi-step metabolic process involving several key organs to be converted into its potent, active form, calcitriol.

Over 90% of our body's vitamin D is synthesized through sun exposure, but it is actually an inert prohormone that must undergo a series of metabolic steps to become biologically active. This activation cascade unlocks its potent hormonal form, which goes on to activate a vast array of physiological processes, from regulating mineral balance to modulating the immune system.
