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.

  9. Significant cardiovascular event in the past 6 months. Participants with no significant cardiovascular event on stable medication may be included after assessment by the QI on a case-by-case basis
  10. History of or current diagnosis with kidney and/or liver diseases as assessed by the QI on a case-by-case basis, with the exception of history of kidney stones in participants who are symptom free for 6 months
  11. Self-reported confirmation of current or pre-existing thyroid condition. Treatment on a stable dose of medication for at least 3 months will be considered by the QI
  12. Major surgery in the past 3 months or individuals who have planned surgery during the course of the study. Participants with minor surgery will be considered on a case-by-case basis by the QI
  13. Cancer, except skin basal cell carcinoma completely excised with no chemotherapy or radiation with a follow up that is negative. Volunteers with cancer in full remission for more than five years after diagnosis are acceptable
  14. Individuals with an autoimmune disease or are immune compromised as assessed by the QI
  15. Self-reported confirmation of a HIV-, Hepatitis B- and/or C-positive diagnosis as assessed by the QI
