If you are interested in apple cider vinegar, you have two realistic choices: the bottle of liquid in the grocery aisle, or a gummy. They are sold as versions of the same thing. On the points that matter for comparing with research, they are quite different.

This article compares them point by point. It does not tell you which to choose. That depends on what you want it for and whether you would actually drink vinegar.

Side by side

	Liquid vinegar	Gummies
Form	Fermented liquid, about 5% acetic acid	Vinegar powder dried onto a carrier, set in a gummy
Acetic acid per serving	About 750 mg per tablespoon	Usually not stated
Used in the research	Yes	No
Sugar	None, or a trace	Usually 1 g to 2 g per gummy
Acid contact with teeth and throat	Yes, unless well diluted	Minimal
Taste	Sharp and sour	Sweet, fruit flavored
Added nutrients	None	Often B vitamins
Portable	No	Yes

Acetic acid: the number that matters

Acetic acid is the compound researchers think is responsible for vinegar’s effects. Liquid apple cider vinegar is typically about 5 percent acetic acid, and US labels often state the acidity. A tablespoon therefore supplies about 750 mg.

The trials used that kind of amount. A 12-week weight trial used 15 mL or 30 mL a day, supplying 750 mg or 1,500 mg of acetic acid. A 2021 meta-analysis of apple cider vinegar trials found most used 15 mL to 30 mL a day.

Gummies use vinegar powder. A typical gummy lists 400 mg to 500 mg of powder. How much of that is acetic acid depends on the powder, and most labels do not say. If the powder had the same 5 percent strength as liquid vinegar, a 500 mg gummy would hold about 25 mg of acetic acid, and it would take about 30 gummies to equal one tablespoon.

That figure is an illustration based on an assumption, not a measurement of any product. Some powders may be stronger. The point is that without a stated acetic acid content you cannot do the comparison at all.

Evidence

All the human evidence comes from liquid vinegar or, in a few trials, vinegar in capsules or drinks. A 2017 meta-analysis found that vinegar with a meal lowered the rise in blood sugar and insulin afterwards. A 2021 meta-analysis found small reductions in fasting blood sugar and total cholesterol, mainly in people with type 2 diabetes and in trials longer than eight weeks.

A 2020 systematic review of 13 human studies concluded that the evidence is insufficient because good-quality research is lacking. So the liquid has modest, uncertain evidence. Gummies have none of their own. Whether the liquid’s findings transfer to a gummy depends on the acetic acid dose, which brings you back to the label.

Sugar

Liquid vinegar contains essentially no sugar. A gummy needs sugar or a substitute to be a gummy. One to two grams per gummy is typical, and suggested servings run from two to six gummies a day.

Gummies per day	Sugar at 2 g per gummy
2	4 g
4	8 g
6	12 g

The American Heart Association suggests no more than about 25 g of added sugar a day for women and 36 g for men. Twelve grams from a supplement is a meaningful share of that. It also sits awkwardly with the main reason people take vinegar, which is blood sugar. See added sugar in gummies. Sugar-free versions exist and use sweeteners such as sugar alcohols. Our guide to sweeteners in zero sugar gummies covers what to expect from those.

Teeth and throat

Vinegar is acidic. Drunk undiluted or sipped slowly, it can irritate the throat and soften tooth enamel. Dentists advise diluting it well, drinking it with a meal, using a straw and rinsing with water afterwards. Do not brush immediately after, because softened enamel wears more easily.

A gummy avoids the acid problem. It introduces a different one. Gummies are sticky and contain sugar, which feeds the bacteria that cause decay. Take them with a meal and not last thing at night after brushing.

Stomach

Vinegar slows the rate at which the stomach empties. Some people feel nausea or discomfort from liquid vinegar, especially on an empty stomach. Gummies are generally easier on the stomach, which is consistent with their containing less acid. Sugar-free gummies made with sugar alcohols can cause gas or loose stools in larger amounts.

Taste and sticking with it

This is the gummy’s real advantage. Many people try liquid vinegar for a week and stop because they dislike it. A supplement you do not take does nothing. If taste is the only thing between you and vinegar, there are middle options: dilute a tablespoon in a large glass of water, or use vinegar as a salad dressing with a meal, which is how it was consumed long before anyone studied it.

Added vitamins

Gummies often include vitamin B12 and sometimes folate or other B vitamins. Liquid vinegar has none. Goli Apple Cider Vinegar Gummies, for example, list 1.2 mcg of vitamin B12 per gummy, 50 percent of the Daily Value, along with 500 mg of apple cider vinegar powder. If your B12 intake is low, that has value independent of the vinegar. If you already take a multivitamin, add the amounts together. See the vitamin B12 guide.

Cost

We do not publish prices, but the comparison is easy to do yourself. Divide the price of a bottle of liquid vinegar by the number of tablespoons in it. Then divide the price of a bottle of gummies by the number of days it lasts at the suggested serving. Liquid vinegar is one of the cheapest items in a grocery store per serving. Gummies cost many times more per day. You are paying for flavor, convenience and any added vitamins.

Which suits which person

If you	Consider
Want the form and dose used in research	Liquid, 1 to 2 tablespoons a day, diluted, with meals
Cannot tolerate the taste of vinegar	Gummies, or vinegar in food
Are limiting sugar	Liquid, or a sugar-free gummy
Have sensitive teeth or reflux	Gummies with a meal, or well-diluted liquid through a straw
Also want B12	A gummy that lists it, or a separate B12 supplement
Travel often	Gummies

Cautions that apply to both

Diabetes medication. Vinegar can lower blood sugar after meals. Ask your doctor before adding it.
Delayed stomach emptying. A small study in people with type 1 diabetes and gastroparesis found vinegar slowed emptying further.
Low potassium, or medication that lowers it. Very large amounts of vinegar over years have been linked to low potassium in a case report.
Pregnancy and breastfeeding. Ask your health care provider before taking a vinegar supplement.

Never drink vinegar undiluted, and do not exceed the serving on a gummy label.

The short version

Liquid vinegar is what the research used. A tablespoon has about 750 mg of acetic acid.
Most gummies do not state acetic acid, and on reasonable assumptions contain far less.
Gummies add sugar, up to about 12 g a day at six gummies.
Liquid is hard on teeth and throat unless diluted. Gummies are sticky and sugary.
Gummies win on taste and convenience, and often include B12.
Liquid costs far less per serving.

Common questions

How many ACV gummies equal a tablespoon of vinegar?

It depends on the acetic acid in the powder, which most labels do not state. If a 500 mg gummy were 5 percent acetic acid, about 30 gummies would equal one tablespoon.

Is liquid apple cider vinegar better than gummies?

It is the form used in research and has no sugar. Gummies are easier to take. Neither has strong evidence.

Do gummies protect your teeth compared with liquid?

They avoid the acid, but they are sticky and contain sugar. Take them with a meal.

Can I take both?

There is no studied reason to. If you do, count the total and stop if your stomach is upset.

Are sugar-free ACV gummies better?

They avoid the added sugar. They use sweeteners that can cause gas in some people, and they still usually do not state acetic acid.

Does liquid vinegar have B12?

No. The B12 in gummies is added by the manufacturer.
