What this Trial Is About
Researchers are evaluating the effect of Bragg Apple Cider Vinegar (ACV) liquid on blood sugar levels after eating carbohydrates in healthy adults aged 20 to 50 years. The main goal is to see if there is a difference in blood glucose levels measured over 120 minutes after consuming ACV compared to a placebo. This controlled clinical trial uses a randomized, single-blind, cross-over design to study this question. Participants will consume either one tablespoon of Bragg ACV liquid or four ounces of water as a placebo following a standardized carbohydrate load. The trial involves two study arms where participants receive both treatments at different times. Blood samples will be taken to measure glucose, insulin, and other markers over a two-hour period after intake. The study is sponsored by Bragg Live Food Products and is scheduled to run from August 2025 to March 2026. During the study, participants will undergo blood draws at multiple time points up to 120 minutes post-consumption. Researchers will track blood glucose and insulin levels to assess the impact of ACV versus placebo. Participants will be asked to maintain stable lifestyle habits and comply with dietary guidelines before clinic visits. Safety and adherence will be monitored throughout the study, which involves healthy volunteers without serious medical conditions. Total participation time varies based on study visits.
