Kidney stones are the worst, so Reactions host Alex Dainis made some at home and tested supposed prevention methods to keep them at bay.

Doctors recommend citrate to ward them off, but how is a little lemon in your water going to stop them from forming?

And are all citrus juices the same, or does orange juice prevent kidney stones more than lemon juice or even grapefruit juice?

This week Alex gets the answers.

Reactions is a video series produced by the American Chemical Society and PBS Digital Studios.

The American Chemical Society (ACS) is a nonprofit organization chartered by the U.S. Congress.

ACS’ mission is to advance the broader chemistry enterprise and its practitioners for the benefit of Earth and all its people.
