Beverage Hydration Index of Different Solutions

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 Beverage Hydration Index 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.

Bioimpedance In Pregnancy and Labour: A Fluid Balance Concept Study.

The purpose of our study is to find out if using a simple bed side test can tell us information about changes that occur in women's body water content. We would like to check if certain medical conditions could affect body water contents.

Potassium, Hydration, Cardiovascular, and Kidney Study (PHACKs)

Compared with White Adults, Non-Hispanic Black Adults are at an elevated risk of developing cardiovascular disease (CVD) and end stage chronic-kidney disease (CKD), two of the leading causes of death in the United States. Inadequate hydration status is associated with risk factors for both CVD and CKD. Prior data show that Black individuals are less likely to be adequately hydrated when compared with their White counterparts. Further, socioeconomic factors have been shown to influence hydration practices. Inadequate hydration influences certain hormones that regulate blood volume and impact blood pressure, but increasing potassium intake may provide some positive effects on normalizing these hormones and blood pressure. Black adults, in particular, are more likely to consume less potassium, have inadequate hydration, and tend to have higher blood pressure. As such, there is a critical need for effective strategies to address racial disparities in hydration and resultant health consequences; as well as establish the role of socioeconomic factors contributing to hydration. Therefore, the investigators are seeking to test the investigators' central hypothesis that water with a potassium supplement will improve hydration and cardiovascular health in young White adults (n = 20, 10 females, 10 males), and to a greater extent in young Black Adults (n = 20, 10 females, 10 males. The investigators will assess measures of blood pressure, arterial stiffness, and biomarkers in the urine and blood samples prior to and following a 14-day hydration intervention of 1) bottled water and 2) bottled water with potassium supplementation (2000mg potassium/day).
