The tart-tasting liquid has been promoted for accelerating weight reduction, decreasing blood sugar and levels of cholesterol, and boosting power. Which of the claims are backed up by science? Fortune requested two dietary specialists to dig into the proof surrounding apple cider vinegar’s potential advantages.
The well being advantages of apple cider vinegar
Apple cider vinegar does have sure healthful properties, that are largely as a consequence of its acetic acid content material. “Acetic acid is a extremely essential metabolite in our our bodies, and the one dietary supply of acetic acid is vinegar,” Carol Johnston, Ph.D., professor of vitamin and affiliate dean within the Faculty of Well being Options at Arizona State College, tells Fortune.
However as a cure-all, apple cider vinegar doesn’t maintain as much as scientific scrutiny. “We don’t have proof to again up lots of the claims,” says Johnston. She ought to know, since she’s been studying vinegar—and never simply the apple cider selection—for many years.
Apple cider vinegar and blood sugar
Essentially the most “sturdy” proof is for apple cider vinegar’s results on blood sugar, Johnston says. In a 2021 overview of 9 research revealed in BMC Complementary Medicine and Therapies, apple cider vinegar lowered fasting blood sugar and HbA1c (a median of blood sugar ranges over three months) in folks with kind 2 diabetes. It additionally introduced down their whole ldl cholesterol.
How may apple cider vinegar decrease blood sugar? Three mechanisms are possible concerned, says Johnston.

“If you’re already implementing weight-reduction plan and life-style modifications, apple cider vinegar might be able to offer you a slight benefit by serving to you management your starvation when you eat much less meals. The scientific proof falls wanting indicating that apple cider vinegar is a magic bullet to provide weight reduction by itself,” Kristine Dilley, a registered dietitian at The Ohio State College Wexner Medical Heart, tells Fortune.

As an example, vinegar may need a future function in treating depression due to its results on mind metabolism. It’s additionally a good source of polyphenols, plant-based antioxidants with anti-inflammatory properties.
Johnston sees the potential. “I feel there’s going to be much more that we’re going to be taught from vinegar sooner or later,” she says.
She additionally notes that vinegar doesn’t have to be of the apple cider selection. Any vinegar with a focus of at the least 5% acetic acid ought to supply the identical advantages—together with purple wine and balsamic vinegar.

Dilley doesn’t advocate utilizing apple cider vinegar capsules or gummies, which aren’t regulated by the FDA. These dietary supplements could not include the quantity of vinegar listed on the label.
Test together with your physician earlier than you are taking apple cider vinegar, as a result of it could actually work together with sure medicines—particularly medicine that decrease blood sugar or potassium, Dilley says. Cooking with it shouldn’t pose an issue together with your medicines.
