A Clinical Trial to Investigate the Acute Effect of Bragg Apple Cider Vinegar Supplement on Blood Glucose Control in a Healthy Adult Population

This research is investigating if a special apple cider vinegar (ACV) supplement can help manage blood sugar levels after someone eats a meal. We're comparing the ACV supplement to a placebo, which is a dummy pill with no active ingredients. Participants will take the supplement shortly before eating a standard meal, and then we'll check their blood sugar. The study is particularly interested in healthy adults who might have slightly elevated blood sugar or other factors linked to metabolic health. The main goal is to find out if the ACV supplement makes a difference in how quickly and how much blood sugar goes up after eating carbohydrates. This could offer insights into new ways to support healthy blood sugar management.

Postprandial Glucose Blood Glucose Concentration

What is this study about?

Imagine you've just eaten a meal, especially one with carbohydrates. Your body breaks this food down into sugar, or glucose, which then goes into your blood. This is a normal process, but keeping your blood sugar levels balanced is important for your overall health. This study is looking at whether a specific apple cider vinegar (ACV) supplement, called Bragg ACV Supplement, can help manage your blood sugar after you've eaten.

We want to see if taking this ACV supplement before a meal makes a difference compared to taking a placebo, which is a pill that looks the same but doesn't contain any active ingredients. By comparing the two, we can tell if any changes in blood sugar are truly due to the ACV supplement. The study will involve a standard meal, so everyone eats the same thing, making the results fair and easy to compare.

The main aim is to understand how the ACV supplement affects how your blood sugar goes up after eating. This kind of research helps us learn more about different approaches to support healthy blood sugar control. It's important because finding ways to keep blood sugar steady can be beneficial for many people's health.

Key takeaways

Tests Bragg Apple Cider Vinegar (ACV) supplement.
Compares ACV to a dummy pill (placebo).
Focuses on blood sugar after eating a meal.
For healthy adults, some with slightly higher blood sugar.
Aims to understand ACV's role in blood sugar control.

Who may be eligible?

To join this study, you need to be a man or a woman between 20 and 65 years old. Women who could become pregnant will need to take a pregnancy test before starting and agree to use reliable birth control methods throughout the study. This includes different types of contraception like the pill, patch, ring, injections, implants, double barrier methods (like condoms and a diaphragm), or an IUD. If you're post-menopausal or have had certain procedures that mean you can't get pregnant, you might also be able to take part.

We are particularly looking for people who are otherwise healthy but may have slightly higher than normal fasting blood sugar levels, or a slightly elevated HbA1c (a measure of average blood sugar over a few months). You might also qualify if you have two or more factors linked to metabolic health, such as a larger waist measurement, slightly high blood pressure, elevated fats (triglycerides) in your blood, or lower levels of 'good' cholesterol (HDL-C). Your weight should have been stable for at least three months before you join.

To ensure fair results, you should be willing to keep your usual lifestyle habits the same throughout the study. This means no big changes to your diet or exercise routine. If you meet these conditions, you may be a good fit for this research.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

Are you between 20 and 65 years old?
If you could get pregnant, are you able to use a reliable birth control method?
Do you have slightly higher than normal fasting blood sugar or a slightly elevated HbA1c?
Have you had a stable weight for the last three months?
Are you willing to keep your lifestyle habits (diet, exercise) consistent during the study?

Answer every question to see your result.

What does participation involve?

If you decide to take part in this study, you will be asked to come to a study center for your appointments. We expect you to take either the Bragg ACV Supplement or a placebo (a dummy pill) for a short period. Before you eat a specific, standard meal provided by the study, you'll take your assigned supplement. We will then carefully measure your blood sugar levels at different times after you've eaten to see how your body responds. The exact number of visits and the total duration aren't fully detailed here, but the study focuses on the immediate effect of the supplement after a meal. You will be given clear instructions at each step.

Potential risks and benefits

Participating in research always has potential benefits and risks. A potential benefit could be learning more about your own blood sugar response and contributing to scientific knowledge about apple cider vinegar and metabolic health. However, there's no guarantee that you will personally benefit from taking the supplement in the study. Potential risks are generally low for this type of research, but could include minor discomfort from blood draws. You will be fully informed of all potential risks before you decide to join. Remember, taking part in any study is completely voluntary, and you have the right to withdraw at any time without giving a reason, and it won't affect any future medical care you receive.

Common questions

What is 'postprandial glucose'?

This simply means your blood sugar levels measured after you've eaten a meal.

What is a 'placebo'?

A placebo is a dummy pill or treatment that looks exactly like the real thing but has no active ingredients. It helps us compare the effects fairly.

Do I need to be ill to join this study?

No, this study is for healthy adults, although we are particularly interested in those with slightly elevated blood sugar levels or some specific health markers.

Will I know if I'm taking the ACV or the placebo?

No, this is a 'blinded' study, meaning neither you nor the research team will know whether you are receiving the ACV supplement or the placebo. This helps make the results more reliable.

What is 'HbA1c'?

HbA1c is a blood test that shows your average blood sugar levels over the past two to three months.
