Vitamin D, its importance and vitamin D supplementation in patients with osteoporosis

Abstract

Ocean phytoplankton has been synthesizing vitamin D for 750 million years. The first complete clinical description of vitamin D deficiency was published in 1645 by Daniel Whistler in his doctoral dissertation, and five years later, in 1650, by Francis Glisson, Tractatus de rachitide sive morbo puerilii.
