Vitamin D Through the Centuries: A Journey from Rickets to Hormonal Regulation
Dr. Kumar’s Take:
This fascinating historical review charts vitamin D’s evolution from a mysterious cure for rickets to a key hormone regulator impacting everything from bone health to immune function. It reminds us how a nutrient identified through a public health crisis has become central to modern physiology. With widespread subclinical deficiency still common today, we must remember how sunlight and nutrition interplay—and why fortification, sensible sun exposure, and targeted supplementation remain relevant.
