This is a single-center prospective cohort study to evaluate the effect of short-term daily apple cider vinegar (ACV) supplementation on urine chemistry.
Description
The primary objective of this study is to determine whether a two-week course of daily ACV supplementation significantly changes an individual's urine chemistry. The investigators will study this in healthy individuals and individuals with kidney stones.
