Credible study sources show that consuming too much phosphoric acid can put you at serious risk for osteoporosis and a variety of heart diseases. Calcium and phosphorus work together to form and maintain healthy teeth and bones, and both are necessary for this.

Excessive phosphorus intake can greatly reduce the amount of calcium in the body and lead to bone loss or weakness. It can also reduce your body’s ability to use other minerals such as iron, zinc, and magnesium.
