Summary
In this study, the impact of two electrolyte hydration stick products (Hydramin containing an electrolyte/amino acid formulation and an identical electrolyte product with the amino-acids replaced with carbohydrate, dextrose) dissolved in 1 liter of water will be assessed and compared to a control (1 liter Smart Water). It is hypothesized that the addition of amino acids and glycine should improve the BHI above water alone and perform comparably to the carbohydrate rich solution. This study will focus on general population (not athletes) and follow very similar approaches used in previous studies within the Center for Nutraceutical and Dietary Supplements Research, with the addition of blood glucose testing and body water measurements. Hydration will be assessed via fluid balance (the difference between the amount of water consumed and passed as urine) and calculations of beverage hydration index (the relative amount of urine passed after consumption of a drink compared to water)as well as time in positive fluid balance, and specific gravity, and sodium and potassium in urine. Blood glucose before and following consumption using finger pricks and a glucometer will also be assessed.
Eligibility
Inclusion Criteria18
- Be age 18 years or older
- male or female
- have a body mass index (BMI)between 18.5-35 kg/m2 (not morbidly obese)
- Be engaged in moderate physical activity, defined as ≤5 hours/week of aerobic exercise

- Not have other conditions that are likely to alter fluid balance or be negatively affected by changing electrolyte levels/hydration status (as determined by Nurse practitioner)
- Not be consuming any medication which may alter fluid retention/electrolyte levels such as SSRIs (Selective Serotonin Reuptake Inhibitors), sodium-glucose co-transporter 2 (SGLT2) inhibitor (for type 2 diabetes), laxatives, diuretics, Apremilast, chemotherapy, or lithium. (Medications will be reviewed by Nurse practitioner)

- Not be a tobacco user
- Not be following a specialized dietary pattern that may alter findings (e.g., low carbohydrate/ketogenic diet, carnivore diet, intermittent fasting etc.)
- Arrive to lab for visits euhydrated (USG 1.005-1.020)
- Have the ability and willingness to fast (consume water/treatments only) for 15 hours (10 hours prior to lab visits not including screening)
- Not be enrolled in another clinical study within 30 days of the first study visit
- Be without active infection or illness of any kind
- Not be pregnant or breastfeeding
- Not have surgery in the previous 4 months
