What this Trial Is About
This research aims to compare the hydration effects of two electrolyte hydration stick products and plain water in healthy adults. The study focuses on the general population rather than athletes and evaluates how adding amino acids or carbohydrates to electrolyte solutions impacts hydration. Researchers will assess hydration by measuring fluid balance, beverage hydration index, urine composition, and blood glucose levels. Participants will attend multiple visits during which they consume one liter of a randomly assigned solution in four equal parts over 30 minutes, followed by four hours of monitoring. The solutions tested include a Hydramin electrolyte and amino acid drink, an electrolyte and carbohydrate drink, and plain water. Each participant experiences all three beverages in varied orders across visits. Throughout the study, participants undergo various assessments including urine tests for sodium, potassium, and specific gravity, blood glucose monitoring using finger pricks, body water measurement, and mood and digestive questionnaires. Vital signs such as blood pressure and heart rate are also recorded at multiple time points. The total observation for each visit spans about 4.5 hours, allowing detailed monitoring of hydration and metabolic responses.
