Why phosphorus matters for seniors
Phosphorus is the body’s second most abundant mineral after calcium. It occurs naturally in a variety of foods and is also available as a dietary supplement. Due to its high reactivity, phosphorus does not exist in its free elemental form on Earth. Most of the body’s phosphorus (about 85%) is stored in bones and teeth, where it plays a vital role in maintaining their structure and strength.
Beyond its role in skeletal health, phosphorus is crucial for generating adenosine triphosphate (ATP), the energy currency of the body. It also contributes to the formation of nucleotides, which are the building blocks of DNA and RNA. Phosphorus supports the growth, maintenance, and repair of all tissues and organs throughout the body.
Additionally, phosphorus is essential for enzyme activation, regulating pH levels in the extracellular fluid, and enabling gene transcription. When combined with B vitamins, phosphorus aids kidney function, nerve signaling, muscle contraction, and helps maintain a normal heartbeat.
For older adults, the recommended daily intake of phosphorus is 700 milligrams. Foods rich in phosphorus include chicken, seafood, dairy products, and nuts.
Elevated phosphorus levels can result from kidney disease and are linked to a higher risk of heart disease. Conversely, phosphorus deficiency can lead to increased susceptibility to infections, muscle weakness, and confusion.
