Not only that, but phosphate is a salt of phosphoric acid, therefore very active chemically. Most pharmaceutical products are precipitated as salts, making them stable on the shelf until absorbed by the body, when the hydrochloride portion of the active compound readily disassociates. While considered stable as the naturally occurring element, phosphorus is mildly radioactive, since nothing is ever found as a totally pure element. It is integral to life. Which begs the question, is radiactivity as chaotic as we think?
