Vitamin D Science

Vitamin D Research

Vitamin D is one of the oldest hormones, having been produced by life forms for over 750 million years. Phytoplankton, zooplankton, and most animals that are exposed to sunlight have the capacity to make vitamin D. In humans, vitamin D is critically important for the development, growth, and maintenance of a healthy body, from gestation until death.

We invite you to browse the various studies to be found in the sections below and see for yourself the scientific evidence of just how vital vitamin D is to life. To view listing of studies for an area of interest, click on corresponding heading below. Note: Lists are not all-inclusive.

Announcement: Due to the time-intensive project currently underway of our complete website overhaul, we are unable to keep our Vitamin D Research section updated with the latest research. We apologize for the inconvenience, but would like to assure you that our new website — with full PubMed integration — will have all the latest research on vitamin D, updated in real time.
