Phosphorus binders work by binding to excess phosphorus in the gut and preventing its absorption into the bloodstream. These medications can effectively reduce phosphorus levels in those with kidney disease, but they do have side effects such as constipation and upset stomach. Natural remedies for reducing phosphorus levels include increasing the intake of fruits and vegetables, reducing the intake of high-phosphorus foods like dairy products and processed meats, and drinking plenty of water. There are tons of kidney friendly drinks to try! High levels of phosphorus can negatively impact bone health, so it is important to consider the role of vitamin D in phosphorus absorption. For those on renal diets for managing phosphorus levels, it's best to work with a registered dietitian to develop a personalized plan that takes into account individual needs and preferences.
