How the body handles extra phosphate
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study looks at how your body handles extra phosphate (a mineral found in many foods) and whether age or sex changes that response. Researchers will give healthy volunteers more phosphate and measure blood and urine levels to understand the effect.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be a healthy adult, either 18 to 25 years old or 63 to 70 years old.
- Your body weight and height must be within a certain range (body mass index between 18.5 and 26).
- Your blood tests must show normal levels of phosphate, calcium, and parathyroid hormone (a hormone that controls calcium and phosphate).
- Your kidney function must be good (measured by a test called eGFR, which should be 60 or higher).
- Your blood pressure must be in a healthy range (systolic 90–140, diastolic 60–85).
- You must not have certain medical conditions like diabetes, kidney stones, or digestive problems.

This early study looks at how the body’s handling of phosphate may affect aging and bone health. It is meant for people with certain rare genetic conditions that change phosphate levels, to better understand their biology and responses to study tests.
This study looks at how the body handles phosphate in people with chronic kidney disease. It may help researchers understand how to better manage phosphate levels to improve health.
This study looks at how eating different amounts of phosphorus affects your bones and blood calcium and phosphorus. It may help find better dietary recommendations for people with moderate chronic kidney disease.
This study looks at how giving phosphate supplements affects a hormone called FGF23 in patients with low blood phosphate levels. It aims to help understand how the body responds to treatment.
This trial studies whether eating extra phosphate changes how well you can exercise and how much visceral (deep belly) fat you have. Because it is a crossover study, you would likely try different phosphate amounts on separate occasions.
This study uses a special MRI scan to look at phosphorus levels in the muscles of people with phosphate diabetes (a condition where the body loses too much phosphate through the kidneys). It aims to better understand how this condition affects muscles and may help guide future treatments.
