Apple Cider Vinegar: How to Include It in Your Routine

Including apple cider vinegar in your routine is simple: dilute one teaspoon (about 5 ml) in at least 200 ml of water and drink it before a main meal, through a straw if possible, and only increase to one tablespoon (15 ml) if you tolerate it well. What needs more attention is not the dose itself, but the form (never neat), the timing and what you expect to get from it — because the available evidence points to modest effects limited to some metabolic parameters, not a transformation of body composition.

This guide explains what the trials actually measured, in which populations, for how long and at what doses, so you can decide with information — and not on the basis of social media promises. If you are looking first for the general background on the ingredient, it is worth reading the apple cider vinegar page.

What happens in the body when you take apple cider vinegar

Apple cider vinegar is, chemically, acetic acid diluted in water, with traces of other compounds from fermented apple. The most discussed mechanism in the literature is delayed gastric emptying: food reaches the intestine more slowly, which can translate into a gentler rise in glucose after eating and a feeling of fullness that lasts longer. A second proposed mechanism is interference with digestive enzymes, reducing the speed at which carbohydrates are broken down into sugar.

None of this is instant or dramatic, and it depends greatly on the meal, the person and consistency. Vinegar is not a medicine and does not replace treatment for any health condition.

What the trials say: concrete numbers

A 2025 meta-analysis brought together 10 randomised controlled trials, with 789 adults with type 2 diabetes and/or excess weight, who took apple cider vinegar for at least 4 weeks. In that population, daily consumption significantly reduced body weight, BMI and waist circumference, but had no significant effect on the remaining body composition parameters analysed ¹. Note the population: these results were not obtained in healthy adults without excess weight.

An earlier meta-analysis, from 2021, with 9 studies and 10 treatment arms in adults, found significant reductions in total cholesterol, fasting plasma glucose and HbA1c with apple cider vinegar consumption ². A broader meta-analysis, with 25 clinical trials and 1320 adults, observed significant improvements in fasting glucose, HbA1c and total cholesterol, but not in BMI, fasting insulin, triglycerides, LDL-C or HDL-C; in the subgroup analysis, the most consistent reductions occurred in people with diabetes ³.

A 2023 network meta-analysis, which compared six plants in adults with type 2 diabetes (44 trials, 3130 participants), placed apple cider vinegar as the option with the greatest effect on reducing fasting glucose and one of the two with a significant effect on HbA1c ⁴. These data are interesting, but they refer to people with type 2 diabetes — not to everyone.

Doses used in studies and what a gummy label says

In the trials, the most frequent doses are between 15 and 30 ml per day of liquid vinegar, always diluted, and some studies used capsules with fixed doses. In a 12-week randomised trial in 94 women with polycystic ovary syndrome taking metformin (1500 mg/day), the dose tested was 1500 mg per day in capsules, in addition to the usual treatment ⁵. This is a clear example that the dose in a capsule or gummy is not equivalent, in volume, to a spoonful of liquid vinegar.

TuttiBear Appetite Control Gummies provide 1000 mg of apple cider vinegar per serving of 2 gummies, in a jar of 60 gummies, and the directions on the label are to chew 2 gummies per day, preferably after a meal. The formulation also includes vitamin B6 (1 mg, 71% NRV), folic acid (400 µg, 200% NRV), vitamin B12 (2.4 µg, 96% NRV), iodine (100 µg, 67% NRV), pomegranate juice powder (80 mg) and beetroot juice powder (80 mg). Doses used in studies are not dosing instructions: always follow the label of the product you choose.

The iodine in the gummies contributes to normal energy-yielding metabolism and to the normal functioning of the thyroid ⁶; vitamin B6, folic acid and vitamin B12 contribute to normal energy-yielding metabolism ⁶. These are the authorised claims in the EU for these nutrients — there are no authorised claims for apple cider vinegar, so everything stated about it has to come from the cited studies.

How to include it in your routine, step by step

1. Start small. One teaspoon (5 ml) diluted in at least 200 ml of water, once a day.
2. Choose the moment. The evidence on the effect on post-meal glucose points to taking it before meals with more carbohydrates; there is more detail in the article on the best time to take apple cider vinegar.
3. Protect your teeth. Use a straw, do not brush your teeth immediately afterwards and rinse your mouth with plain water.
4. Increase only if you tolerate it. If there is no discomfort, you can go up to one tablespoon (15 ml) per day, always diluted — the upper limit used in most studies.
5. Be consistent. More than the form, it is regularity over weeks that allows you to assess whether it makes sense for you.

Practical ways to include it without drinking a sour glass

Drinking diluted vinegar is the most direct method, but not the only one. You can use it as a culinary ingredient — a drizzle on salads, roasted vegetables or sauces — and you get the same acetic acid, with the advantage of it being naturally diluted in the food. You can also add it to water with a slice of lemon, as long as you do not add sugar.

The other option is gummies. They have a clear practical advantage: a fixed dose, no measuring or diluting, and none of the strong taste of the liquid, which can help those who find it hard to keep up the routine. It is important to be honest about the limits: there are no studies that directly compare gummies with liquid vinegar in terms of effect on the body, so it cannot be said that one form is superior to the other. What is known is that the active ingredient is the same and that the dose on the label is what counts. You can see the available options on the apple cider vinegar gummies page and compare the two approaches in the article apple cider vinegar vs. gummies.

Quick comparison: liquid, capsules and gummies

Form	Typical dose	Practical advantages	Watch out for
Diluted liquid vinegar	5–15 ml per dose, in 200 ml of water	Flexible, easy to adjust, also suitable for cooking	Strong taste, risk to tooth enamel and gastric irritation if poorly diluted
Capsules	Fixed doses, such as 1500 mg/day in trials	No taste, exact dose	Not equivalent in volume to liquid vinegar; check the label
Gummies	E.g. 1000 mg per serving of 2 gummies (Appetite Control Gummies)	Practical when out of the house, no dilution, fixed dose	Contain polyols; excessive consumption may have laxative effects

Who should be careful before starting

Apple cider vinegar is not suitable for everyone. If you have a gastric ulcer, active gastritis, severe reflux or dental enamel problems, the acid can worsen symptoms. If you take medication regularly — in particular for diabetes, diuretics or insulin — speak to a health professional first, because vinegar can affect the glucose response and potassium levels. In case of pregnancy, breastfeeding, illness or taking medication, consult a health professional before consuming; the same applies to children, who should not be given doses of vinegar. There is more context in the article on whether apple cider vinegar is safe for daily use.

A practical sign of excess is digestive discomfort: heartburn, nausea or throat irritation. If these appear, reduce the dose or stop. The gummies contain polyols and excessive consumption may have laxative effects, so you should not exceed the dose stated on the label.

What vinegar does not do

Many unsupported claims circulate. Apple cider vinegar does not burn localised fat, does not speed up metabolism in any relevant way and does not change blood pH — the body regulates that value strictly, regardless of what you eat. It also does not replace a balanced diet or a calorie deficit, which remain the basis of any sustainable weight loss. If you want to separate what has scientific support from what is myth, see the article on myths and truths.

An example of a two-week routine

Week 1: one teaspoon (5 ml) diluted in 200 ml of water, before lunch or dinner, with a straw. Note how you feel — fullness, digestive comfort, heartburn. Week 2: if there is no discomfort, keep the same dose or go up to one tablespoon (15 ml) per day, always diluted, respecting the upper limit of 15 ml daily used in most studies. If you prefer gummies, the practical equivalent is to follow the label directions (for example, 2 gummies per day, preferably after a meal, with Appetite Control Gummies) and keep that daily intake. After a few weeks, assess honestly: if you notice no difference and there is no discomfort, you can keep it as a habit; if you notice discomfort, stop and speak to a health professional.

The verdict

Including apple cider vinegar in your routine can be a simple and reasonable addition, especially for those looking to soften glucose spikes after carbohydrate-rich meals. The most consistent evidence comes from trials in adults with type 2 diabetes and/or excess weight, with modest effects that are not always replicated across all parameters. Always dilute, start slowly, respect the label of the product you choose and speak to a health professional if you have health conditions or take medication. It is a complement, not a solution.

Frequently asked questions

How should you dilute apple cider vinegar?

Always dilute one teaspoon (about 5 ml) in at least 200 ml of water. Never drink vinegar neat, because the acid can irritate the throat and oesophagus and wear down tooth enamel. Use a straw and rinse your mouth with plain water afterwards.

What is the best time of day to take apple cider vinegar?

The evidence on the effect on post-meal glucose points to taking it before meals with more carbohydrates, about 15 to 30 minutes before. Taking it on an empty stomach has no additional scientific support and may be more irritating to an empty stomach. The most important thing is to keep a regular daily intake.

How many ml of apple cider vinegar per day?

In the trials, the most used doses are between 15 and 30 ml per day of liquid vinegar, always diluted, and some studies used capsules with fixed doses. One tablespoon (15 ml) per day is the upper limit used in most studies. Study doses are not dosing instructions: follow the label of the product you choose.

Do apple cider vinegar gummies work as well as the liquid?

There are no studies that directly compare gummies with liquid vinegar, so it is not possible to say that one form is superior to the other. The active ingredient is the same and what counts is the dose stated on the label. Gummies have the practical advantage of not needing dilution and not having the strong taste, which can help with consistency.

Does apple cider vinegar help with weight loss?

A 2025 meta-analysis with 10 trials and 789 adults with type 2 diabetes and/or excess weight found significant reductions in weight, BMI and waist circumference with daily consumption, but not in all body composition parameters. The effects are modest and do not replace a balanced diet or a calorie deficit.

Who should not take apple cider vinegar?

People with a gastric ulcer, active gastritis, severe reflux or dental enamel problems should avoid it, because the acid can worsen symptoms. Anyone taking regular medication, especially for diabetes, diuretics or insulin, should speak to a health professional first. In pregnancy, breastfeeding, illness or when taking medication, consult a health professional.
