Variation in Urine Electrolytes, pH and Specific Gravity Throughout the Day

Completed · Not applicable

Conditions studied: Healthy

In brief

This study is a prospective study looking at healthy adults who will have urine collected at 4 set times throughout the course of the day. On Day 2, 3, and 4 subjects will drink a bottle of water containing True lemon and on days 2 and 3 double the amount of fluid intake from Day 1. On day 4 the subject will collect urine samples at 4 set times throughout the day. The pH of all of the urine samples will be checked with a urine dipstick and the samples will be sent to Litholink Lab for electrolyte composition analysis.
