Study Summary

The goal of this clinical study is to investigate the efficacy of a Bragg Apple Cider Vinegar (ACV) liquid on postprandial glucose (PPG) excursion compared to a placebo following a standardized acute carbohydrate load. The main question it aims to answer is:

Is there a difference in the incremental area under the curve (iAUC) (from 0 - 120 mins following administration) for venous blood glucose between Bragg ACV liquid and placebo following an acute carbohydrate load.

Participants will [describe the main tasks participants will be asked to consume 750 mg of Bragg Apple Cider Vinegar (ACV) liquid or water and undergo a blood draw to measure glucose, insulin, and future analysis markers.
