Should I let my doctor know I'm taking phosphorus?

Because it can interact with a number of different medicines, you should let your doctor know if you are taking phosphorus supplements. For instance, phosphorus might prevent iron supplements from being absorbed properly in your body. Conversely, some antacids and bile medications might prevent phosphorus from being absorbed. Also, phosphorus may interact with medicines that affect the level of electrolytes in your body, including anti-inflammatory medications and salt substitutes. Additionally, calcium supplements in combination with phosphorus may lead to hardened calcium deposits forming in your body.
