Potassium Bioavailability | Bioavailability of Potassium From Potatoes and Potassium Gluconate

Potassium Bioavailability research study

What is the primary objective of this study?

This study is designed to compare the effect of sources of potassium on uptake and the effect of potassium on blood pressure.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Placebo controlSubjects will consume tablets containing no potassium in addition to a basal diet containing 2336 mg potassium

Low dose potassium gluconateSubjects will consume 720 mg potassium in the form of potassium gluconate tablets daily in addition to a basal diet containing 2336 mg potassium

Medium dose potassium gluconateSubjects will consume 1440 mg potassium in the form of potassium gluconate tablets daily in addition to a basal diet containing 2336 mg potassium

High dose potassium gluconateSubjects will consume 2160 mg potassium in the form of potassium gluconate tablets daily in addition to a basal diet containing 2336 mg potassium

Low dose potatoSubjects will consume 720 mg potassium in the form of potato daily in addition to a basal diet containing 2336 mg potassium

Medium dose potatoSubjects will consume 1440 mg potassium in the form of potato daily in addition to a basal diet containing 2336 mg potassium

High dose potatoSubjects will consume 2160 mg potassium in the form of potato daily in addition to a basal diet containing 2336 mg potassium

High dose French friesSubjects will consume 2160 mg potassium in the form of french fries daily in addition to a basal diet containing 2336 mg potassium

Basal diet controlSubjects will consume a basal diet containing 2336 mg potassium daily
