Are Apple Cider Vinegar Benefits Backed by Research?

Apple cider vinegar benefits are widely claimed, from weight loss to detox. The research is thinner than the claims. Harvard Health reports that most dosing suggestions are 1 to 2 teaspoons before or with meals, and Mayo Clinic cites up to two tablespoons a day. Below: what apple cider vinegar is, what studies show, safety, and how it pairs with probiotics.*

What is apple cider vinegar?

Apple cider vinegar comes from apples that are crushed, distilled and then fermented, according to Harvard Health. Its high level of acetic acid, or perhaps other compounds, may be responsible for its possible effects. Mayo Clinic describes it as a fermented juice made from crushed apples.*

Some bottles keep "the Mother," a cloudy layer that forms during fermentation; see ACV with the Mother explained. Apple cider vinegar also comes in pills and capsules, compared in apple cider vinegar capsules vs liquid.*

What does research say about apple cider vinegar benefits?

*Table entries summarize the cited sources. These statements have not been evaluated by the FDA.

Does apple cider vinegar help with weight loss?

Harvard Health describes a 2009 trial of 175 people who drank a daily beverage with 0, 1 or 2 tablespoons of vinegar, supplying 0, 750 or 1,500 mg of acetic acid. After 12 weeks, the vinegar groups lost 2 to 4 pounds more and had lower triglycerides. The lead author was listed at Mizkan Group Corporation, and the trial did not test apple cider vinegar specifically.*

A 2018 study assigned 39 people to a reduced-calorie diet with or without apple cider vinegar for 12 weeks. Both groups lost weight, and the vinegar group lost more. Harvard Health calls the study quite small and short-term and concludes that the evidence is not compelling.*

Mayo Clinic states that experts have not found meaningful weight loss or long-term hunger control. For one common pairing, see L-carnitine vs apple cider vinegar.*

How might apple cider vinegar affect blood sugar after meals?

Harvard Health reports that apple cider vinegar might help lower blood sugar levels after a meal by changing how foods are absorbed from the gut. Harvard Health links this to blocking starch absorption and calls it a topic for further study.*

Think of the effect as a slower checkout lane. Starch from a meal still gets through, but vinegar may let it pass more slowly, so blood sugar rises less sharply. That is a possible mechanism, not a proven result.*

Harvard Health also notes that vinegar can alter insulin levels, and Mayo Clinic lists insulin among the medicines apple cider vinegar may affect. Anyone who uses insulin should ask a healthcare provider first.*

Is apple cider vinegar a detox?

Harvard Health notes that vinegar compounds have been used for thousands of years for detoxification, strength and other purposes. Neither Harvard Health nor Mayo Clinic reports evidence that apple cider vinegar removes toxins. Trio Nutrition reviews the related claim in whether a gut cleanse aids digestion.*

How do apple cider vinegar and probiotics fit together?

The National Center for Complementary and Integrative Health (NCCIH) defines probiotics as live microorganisms intended to have health benefits. The most common are Lactobacillus and Bifidobacterium bacteria. NCCIH notes that probiotics might help the body maintain a healthy community of microorganisms or influence the immune response.*

NCCIH adds that different probiotics may have different effects, and in most cases it is not yet known which ones help, how much to take or who benefits. Apple cider vinegar is not a probiotic; some products simply combine the two.*

Trio Nutrition covers the probiotic side in how a probiotic supplement supports gut health, apple cider vinegar and probiotics for gut health, whether probiotics help with regularity, probiotics and women's urinary tract health and the science of immune support supplements.*

Is apple cider vinegar safe to take every day?

Mayo Clinic states that most people can use commercial apple cider vinegar safely in small amounts, and that people may be less likely to have side effects when it is added to food rather than drunk. Harvard Health advises diluting it.*

The bottom line on apple cider vinegar benefits

Apple cider vinegar is a fermented food acid with a few small studies on weight and blood sugar after meals. Mayo Clinic does not expect it to cause weight loss, and no source here supports detox claims. Dilute it, keep amounts small, and check with a provider about medicines.* If you consider a supplement, talk with your healthcare provider first.

Can apple cider vinegar help with weight loss?

In a 2009 trial described by Harvard Health, 175 people who drank 1 or 2 tablespoons of vinegar a day lost 2 to 4 pounds more over three months, but the vinegar was not apple cider vinegar specifically. A 2018 study of 39 people on a reduced-calorie diet for 12 weeks found more weight loss with apple cider vinegar, and Harvard Health calls it small and short-term.*

Harvard Health also notes that vinegar can alter insulin levels.

With these combinations, potassium levels may become low, and Mayo Clinic notes that the body needs potassium for nerve and muscle cells to work properly.*

What are probiotics?

The National Center for Complementary and Integrative Health (NCCIH) defines probiotics as live microorganisms that are intended to have health benefits when consumed or applied to the body. In the 2012 National Health Interview Survey, about 4 million U.S. adults (1.6%) had used probiotics or prebiotics in the past 30 days. The most common probiotics are bacteria from groups called Lactobacillus and Bifidobacterium, and some yeasts are also used. NCCIH, in a fact sheet last updated in July 2019, reports that probiotic use by U.S. adults quadrupled between 2007 and 2012.*
