Effects of a Carbonated Water Enriched With Amino Acids and Chromium Picolinate (Good Idea®) on Glucose Homeostasis.

September 2, 2019 updated by: DoubleGood AB

A Randomized, Double-blind, Placebo-controlled, Crossover, Single-center, Proof of Concept Study to Evaluate the Efficacy of GoodIdea® on Glucose Homeostasis in a Healthy Population.

It has previously been shown in healthy subjects, that a carbonated water containing a mix of amino acids and chromium picolinate can decrease postprandial blood glucose. Based on these findings, a flavored sparkling water product called Good Idea® with a proprietary blend of five amino acids and chromium picolinate has been developed. This product, along with an identical placebo, are included in this study to evaluate the effects on postprandial blood glucose in healthy, overweight adults when consumed with a standardized, high glycemic test meal. The study will be conducted in a cross-over design, double-blinded and placebo controlled, including 45 participants. The primary endpoint of the study is the incremental area under the curve (iAUC) for capillary blood glucose within 180 minutes after ingestion of the meal.
