Methionine supplement for calcium phosphate kidney stones
Part of Kidney & urinary clinical trials.
This study tests whether taking a methionine supplement can help lower the pH of urine, which might prevent calcium phosphate kidney stones from forming. It looks at whether this supplement is safe and helpful for people who have had these types of stones.
Summary written for real people, not researchers, by Clin2.

This study looks at genes in people who form calcium phosphate kidney stones. It may help doctors understand why some people make this type of stone.
This study tests whether giving a specific gut bacteria can help people with calcium oxalate kidney stones. It looks at whether the bacteria can change how the body processes oxalate, which may reduce stone formation.
This study tests if a medication can make your urine less acidic, which may help prevent kidney stones from forming or coming back. It compares the effects of the medication on urine acidity to see if it is a good prevention strategy.
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 tests a supplement called tributyrin, which the body turns into butyrate, a substance that may help prevent calcium kidney stones from forming. If you have had a calcium kidney stone in the past 3 years, this trial will see if taking this supplement can reduce the risk of future stones.
