Medicine depends on minerals far more than most people realize. Many life-saving drugs, diagnostic agents, medical devices, and nutritional supplements either contain minerals directly or are manufactured using mineral-derived materials. From calcium tablets that strengthen bones to platinum-based chemotherapy drugs that treat cancer, minerals play an essential role in modern healthcare.
Minerals in medicine support disease prevention, diagnosis, treatment, rehabilitation, and medical research. Some minerals become active pharmaceutical ingredients, while others are used to manufacture medical equipment, imaging agents, dental materials, prosthetics, and hospital supplies.
Understanding minerals in medicine demonstrates the close relationship between geology, mineralogy, chemistry, pharmacy, and medical science.
