Regulating Urine pH Levels to Alleviate Chronic Joint Pain

Summary

This study aims to determine the causal relationship between regulating urine pH levels between 7.0 and 7.5 and decreasing chronic joint pain. The investigators hypothesize that maintenance of an alkaline urinary pH will result in a decrease in personally reported levels of chronic joint pain using a citrate treatment regimen.
