Choose Your Antacids Carefully

Phosphorus is second only to calcium as the most abundant mineral in the body and in bones. And you get plenty in your diet—but certain antacids could be depleting your supply.

hosphorus is a vital part of every cell's genetic material. J7 Strong bones depend on it. Along with calcium, phosphorus lends structure to your skeleton, according to Hillary M. Wright, R.D.

Phosphorus is found in protein-rich foods, so if you're eating right, you're getting what you need, says Wright—unless you're taking antacids.

Wright warns that chronic consumption of antacids that contain aluminum hydroxide causes phosphorus excretion from the body, resulting in bones that can weaken to the point of fracture. Switch to antacids like Turns, phich is made of calcium carbonate. Chewing on Turns contributes to your daily calcium quota, while preserving phosphorus.
