Will Apple Cider Vinegar Lower Blood Sugar?

Acetic acid, the primary ingredient in apple cider vinegar, may help with weight loss and provide additional health advantages like improved cholesterol and blood sugar control.

Can apple cider vinegar quickly reduce blood sugar?

Those who consumed the apple cider vinegar over the course of two days decreased their fasting blood sugar levels by up to 6% compared to trial participants who drank water and ate cheese before night.

What daily dosage of apple cider vinegar is recommended for diabetics?

Acetic acid, a cocktail of apple cider vinegar and honey, tablets, and cider vinegar are just a few of the different ways that apple cider vinegar has been marketed in the US. Additionally, it is coupled with food items, botanicals, and supplements. To make apple cider vinegar, apples are ground into a pulp and juice slurry, and acetic acid is then added along with yeast and sugar. Apple cider vinegar has been asserted to promote weight reduction and help with a wide range of illnesses, including arthritis, asthma, colitis, food poisoning, gastrointestinal and skin issues. It has also been claimed to work alone or in conjunction with other substances, such as grapefruit or kelp. [1] A cup of water containing 2 tablespoons of apple cider vinegar may help relieve food poisoning symptoms, help people lose weight, or lower cholesterol when combined with ginger, cayenne, and citrin, according to anecdotal stories and folklore. [1,2] However, there is little scientific data to back up these assertions.

The supposed medical benefits of apple cider vinegar are thought to work through a number of different processes, including an antibacterial effect and acidity causing a hypoglycemic effect. Although there is inadequate evidence from scientific controlled trials to show that apple cider vinegar is beneficial for the range of medical diseases for which it has been used, enough preliminary data has emerged from recent studies in individuals with diabetes to support more research.

Review of the Evidence

For a period of 12 weeks, medicinal vinegar taken as a vinegar solution (2800 mg daily) was contrasted with acetic acid pills (30 mg daily), used as a placebo, and eating a pickle every day. [3]The researchers discovered that people with type 2 diabetes or insulin resistance who received vinegar along with a carbohydrate meal experienced lower postprandial glucose levels. When compared to the other 2 groups, the liquid vinegar group’s urine pH was observed to have significantly decreased. [4] Elevated levels of aspartate transaminase were discovered to be a sign of hepatic and metabolic pathway action. This group of people, whose mean baseline A1c was 6.3% and who already had their diabetes under control with medication, likewise showed a modest decrease in A1c compared to the pickle (-0.38%) and acetic acid pill (-0.22%) groups. [5] The authors of the study hypothesized that consuming a minimum of 2800 mg of acetic acid daily in the form of vinegar at mealtimes could help diabetics achieve better glycemic control.

Participants were given vinegar along with 50 g of carbs delivered as sliced white bread, and a dose-response relationship was observed between acetic acid intake and postprandial glucose and insulin responses evaluated up to 2 hours after ingestion.

[6] In addition, participants reported feeling fuller after receiving higher acetic acid doses. Another study discovered that adding vinegar to a meal with a high glycemic index—mashed potatoes and low-fat milk—but not a low glycemic index—whole grain bread, lettuce, and low-fat cheese—reduced postprandial hyperglycemia in individuals with type 2 diabetes. [7] This study’s authors hypothesized that acetic acid decreased the pace of stomach emptying, which resulted in a slower absorption of carbohydrates, and that low-glycemic-index meals already had this impact. They came to the conclusion that acetic acid might help diabetics by reducing postprandial glucose.

In a small trial, the impact of consuming 2 tablespoons of apple cider vinegar before night was investigated in patients with well-controlled type 2 diabetes (A1c 6.7%) and obesity (body mass index 29). This group of patients saw a drop in next-morning fasting glucose from 4% to 6%, while having a mean duration of diabetes of 4.9 years. [8] Participants with A1c 6.3% experienced the same effects of vinegar on fasting glucose as those with values between 6.8% and 7.0%.

A study of people with type 1 diabetes showed that 2 tablespoons of vinegar administered with a carbohydrate meal reduced the postprandial surge in glucose at and after 30 minutes. This study also showed a comparable reduction in postprandial glucose.


Vinegar’s effects have been attributed to a number of different modes of action, including slower stomach emptying, inhibition of digestive enzymes, and reduction of muscle glucose uptake.


In conclusion, research on vinegar’s effectiveness for regulating blood sugar levels in people with diabetes is still in its early stages and has limited sample sizes, but future research can test the suggested mechanisms of action. 2 tablespoons of vinegar, whether it be apple cider vinegar or another type, should be taken twice daily. It appears to be safe to consume 2 tablespoons of vinegar with water three times a day and has not been linked to any reports of toxicity. [1] However, microbial contamination has been proven to occur with all food products. [13,14,15] Only hypokalemia and reduced bone mineral density have been linked to prolonged consumption of vinegar over a period of six years as vinegar’s potential side effects. [16] Patients who are interested in utilizing vinegar for glycemic management may participate in a therapy trial with careful monitoring of postprandial and morning fasting glucose levels as well as A1c to determine possible efficacy.

How frequently should apple cider vinegar be consumed to reduce blood sugar?

The Final Verdict. In addition to assisting with blood sugar control and PCOS symptoms, apple cider vinegar can also aid in weight loss. 12 tablespoons (1530 ml) combined with water is the usual dosage, which should be taken either before or after meals.

How may blood sugar levels be swiftly lowered?

We only include items we believe our readers will find useful. We might receive a small commission if you make a purchase using the links on this page. Here is how we work.

The quickest way to lower high blood sugar, also known as hyperglycemia or high blood glucose, is to take fast-acting insulin. Another quick and efficient technique to reduce blood sugar is through exercise.

When insulin levels are low, extremely high blood sugar levels can cause diabetic ketoacidosis (DKA). A medical emergency has occurred.

DKA symptoms include:

  • breathing difficulty
  • fruity-smelling breath
  • nauseous and dizzy
  • extremely dry mouth

If you’re unsure of what to do, call your doctor for assistance on how to take an insulin dose and whether you should visit the emergency department.

This article discusses how to immediately drop your blood sugar, when to visit the ER or a doctor, and strategies for controlling high blood sugar.

What beverage reduces blood sugar?

Having a nutritious diabetes meal plan is essential for controlling your blood sugar when you have prediabetes or diabetes. Choosing healthy foods and beverages can sometimes be challenging, but these 10 suggestions might help you maintain a healthy weight.

1. Any type of bean

Beans, whether they are garbanzo, kidney, pinto, black, or lentils, have a low glycemic index. This means that because their carbs are given gradually, blood sugar spikes are less likely to result from them. One study found that consuming a cup of beans every day for three months as part of a low-glycemic index diet decreased HbA1c by 0.5 percentage points. This is because beans are so advantageous.

Apples, 2.

Although you might believe that fruit has no place in a diabetic meal plan, apples are also low glycemic. One method of controlling blood sugar levels is to choose foods that are low or medium on the glycemic index, such as apples. A daily apple serving also offers advantages. They are fat-free and rich in fiber and vitamin C. Not to mention a convenient and transportable snack choice.

Try it! Pack an apple for lunch or snack on one in between meals. For a warm treat, bake them and add cinnamon.

Almonds 3.

Magnesium, a mineral that may improve how well your body uses its own insulin, is abundant in these crunchy nuts. Consider including more almonds in your diet; a dietone ounce (or about 23 whole nuts) has about 20% of the daily recommended amount of this mineral, which helps to regulate blood sugar. Additionally, nuts like almonds are a wonderful approach to help control blood sugar levels because they are high in monounsaturated fatty acids, protein, and fiber.

Try it! Pack almonds in single-serve containers in one-ounce servings for a wholesome on-the-go snack.

Spinach 4.

This leafy green is high in fiber and magnesium, both of which help control blood sugar levels, and only has 21 calories per cooked cup. Additionally, spinach is a versatile choice because you may eat it fresh, cooked, pureed, sauteed with olive oil, etc.

Try it! You can substitute baby spinach for lettuce in a salad or add a big handful to your next smoothie.

Chia Seeds, No. 5

You may have heard that one of the best things you can do to lower your blood sugar is to lose or manage weight. Chia seeds may be of assistance. In one study, persons with diabetes who consumed 1,000 calories per day with an ounce of chia seeds for six months lost four pounds and an inch and a half off their waistlines. These gems not only contain a ton of fiber, but also protein and 18% of the daily necessary calcium intake.

Try it! Half a cup of chopped fruit, one cup of nonfat or one percent milk, and a quarter cup of chia seeds are combined. Enjoy for breakfast the following morning after being refrigerated over night.

Glucerna Shakes and Bars, number six

Eating healthy can be challenging if your day is hectic. Glucerna smoothies and bars can simplify your life. They are produced by Abbott and contain combinations of carbohydrates that are slowly absorbed and digested to lessen blood sugar increases. They’re a sensible, portion-controlled alternative with less than 200 calories each shake and less than 160 calories per bar.

Try it! No matter how hectic your day is, keep a couple Glucerna bars or shakes in your desk or car so you’ll always have a nutritious snack on hand.

A 7. Blueberry

Another fruit alternative is blueberries, which have strong scientific support for their health advantages. Compounds found in blueberries have been demonstrated to lower the risk of heart disease and enhance insulin sensitivity. According to one study, obese individuals with insulin resistance who consumed the equivalent of around two cups of blueberries every day had improved insulin sensitivity. Blueberries are an excellent method to get your fill because they’re also a great source of fiber and other nutrients like vitamin C and antioxidants.

Try it! Serve plain, unsweetened yogurt with a half-cup of fresh blueberries (or defrosted, frozen blueberries). A cup of blueberries can also be added to your smoothie.

Oatmeal, 8.

Not only is oatmeal healthy for your heart. Additionally, it can lower blood sugar. Because they have a lower glycemic index than foods like white bread, bran flakes, or corn flakes, steel cut and rolled oats are a healthier option. Just keep in mind that while rolled and steel cut oats are excellent choices, highly processed instant and quick oats typically rank higher on the glycemic index and are therefore less healthy for blood sugar levels.

Try it!

Choose cooked oatmeal with blueberries made from steel or rolled oats for a filling, delicious breakfast.

9. Curcumin

Curcumin, a compound in this golden spice, may maintain the function of your pancreas and stop prediabetes from developing into Type 2 diabetes. How well does it function? For nine months, researchers gave prediabetic volunteers either 1500 mg of a daily supplement containing curcumin or a placebo. While both groups received the same amount of curcumin, only 16 percent of the placebo group eventually developed diabetes. This study sheds some light on the benefits of an old spice like turmeric in enhancing the body’s sensitivity to insulin.

Try it:

Turmeric is a key ingredient in curry powder. For a boost of curcumin, add some to your next vegetable stir-fry or consult a doctor about taking a supplement.

ten) Chamomile tea

Numerous illnesses have long been treated with chamomile tea. It has antioxidant and cancer-preventive characteristics, and a recent study indicated that it might also help you control your blood sugar levels. Three times daily for six weeks, study participants drank one cup of chamomile tea after meals, and their blood sugar, insulin, and insulin resistance all decreased.

Try it!

Instead of an after-dinner drink, opt for a cup of freshly prepared chamomile tea. For flavor and an additional boost of vitamin C, try adding a piece of lemon.

Is drinking apple cider vinegar in the morning or at night preferable?

ACV can be quite beneficial for those with diabetes who regularly consume it. The fermentation of the juice may delay stomach emptying and reduce blood sugar rises. Consuming ACV has also been demonstrated to improve insulin sensitivity. It may be more advantageous to consume that mixture at night than at any other time of the day.

ACV shouldn’t be consumed by anyone.

The yeast turns the apple sugar into alcohol. The mixture is then combined with bacteria, which causes the alcohol to ferment into acetic acid (1).

Apple cider vinegar is 56% acetic acid. It is categorized as a “weak acid,” yet when concentrated, it still exhibits quite strong acidic qualities.

Vinegar also contains water, traces of other acids, vitamins, and minerals, in addition to acetic acid (1).

Acetic acid and apple cider vinegar have been linked to improved cholesterol levels, reduced blood sugar levels, increased insulin sensitivity, and weight loss in both humans and animals, according to several studies (2, 3, 4, 5).

Sadly, there are few human studies that support the regular use of apple cider vinegar, and additional study is required (6).

Acetic acid, the primary ingredient in apple cider vinegar, may help with weight loss and provide additional health advantages like improved cholesterol and blood sugar control.

Sadly, there are some adverse effects associated with using apple cider vinegar.

While ingesting little amounts is typically okay and healthy, doing so in excess can be detrimental and even dangerous.

Delayed stomach emptying

Apple cider vinegar may slow down the rate at which food leaves the stomach and enters the lower digestive tract, according to small human studies. The bloodstream’s ability to absorb nutrients could be slowed by this.

However, this impact might make persons with diabetes who frequently experience gastroparesis’ symptoms worse.

Due to malfunctioning stomach nerves in gastroparesis, food remains in the stomach for an excessive amount of time and does not empty at a regular rate.

Gastroparesis signs and symptoms include nausea, bloating, and heartburn. Because it’s difficult to forecast how long food will take to digest and absorb, timing insulin with meals can be particularly difficult for persons with type 1 diabetes and gastroparesis.

Ten patients with type 1 diabetes and gastroparesis were the subject of one controlled study.

When compared to drinking normal water, drinking water with 2 tablespoons (30 mL) of apple cider vinegar lengthened the time food stayed in the stomach (7).

More recent studies are required to fully comprehend how apple cider vinegar affects blood sugar levels.

According to research, apple cider vinegar may reduce how quickly food leaves the stomach. People with type 1 diabetes may experience worsening gastroparesis symptoms as a result, making it harder for them to control their blood sugar levels.

Digestive side effects

Studies on both people and animals have discovered that acetic acid and apple cider vinegar can naturally reduce calorie intake by promoting feelings of fullness and reducing desire (8, 9).

However, one controlled study indicates that under some circumstances, dyspepsia may cause a decrease in appetite and food consumption.

The participants who drank a beverage containing 25 grams (0.88 ounces) of apple cider vinegar reported less appetite but also noticeably more nausea, especially when the vinegar was a component of a drink with a bad taste (10).

Although it may aid in appetite suppression, apple cider vinegar can also make you feel queasy, especially if you drink it with something that tastes bad.

Low potassium levels and bone loss

The effects of apple cider vinegar on blood potassium levels and bone health have not yet been subjected to controlled trials.

One case report of low blood potassium levels and bone loss, however, was linked to consuming significant amounts of apple cider vinegar over an extended period of time.

A 28-year-old lady drank 8 ounces (250 mL) of water-diluted apple cider vinegar every day for six years.

She was brought to the hospital due to low potassium levels and further blood chemical problems (11).

In addition, osteoporosis, a disorder that produces brittle bones and is uncommon in young people, was identified as the woman’s illness.

The woman was treated by doctors who think her huge daily doses of apple cider vinegar caused mineral loss from her bones in an effort to balance the acidity of her blood.

Of course, she consumed a lot more apple cider vinegar in this example than the majority of people would in a single day, and she did it every day for a long time.

There is one case report of osteoporosis and low potassium levels that were probably brought on by consuming excessive amounts of apple cider vinegar.

Erosion of tooth enamel

Although studies on soft drinks and fruit juices have received more attention, some evidence suggests that vinegar’s acetic acid may also harm dental enamel.

In one lab experiment, vinegars with pH ranges from 2.73 to 2.95 were used to soak wisdom tooth enamel. After 4 hours, the vinegars caused a 100% loss of minerals from the teeth (13).

As saliva helps to buffer acidity in the mouth and a person wouldn’t retain vinegar in their mouth for four hours, it is important to note that this study was conducted in a lab rather than in a human mouth. However, there is some proof that excessive vinegar consumption may lead to teeth erosion.

A case study revealed that a 15-year-old girl who regularly consumed 1 cup (237 mL) of undiluted apple cider vinegar as a weight-loss aid was responsible for developing serious dental damage (14).

Vinegar’s acetic acid has the potential to erode dental enamel, cause mineral loss, and tooth decay.

Throat burns

Acetic acid from vinegar was discovered to be the most often occurring acid that resulted in throat burns when dangerous liquids accidently consumed by youngsters were examined.

Researchers advised keeping vinegar in childproof containers and treating it as a “strong caustic chemical” (15).

However, according to one case study, an apple cider vinegar tablet that got stuck in a woman’s throat burned her. The woman said that for six months following the incident, she had pain and trouble swallowing (16).

Children’s throat burns from apple cider vinegar’s acetic acid have been reported. One woman had burns on her throat from an apple cider vinegar tablet that got stuck in her esophagus.

Skin burns

When applied to the skin, apple cider vinegar can burn because of how powerfully acidic it is.

In one instance, a 14-year-old girl who followed an internet protocol to remove two moles ended up with erosions on her nose after using several drops of apple cider vinegar (17).

In another instance, an apple cider vinegar-treated leg infection caused leg burns in a 6-year-old boy with many health issues (18).

Additionally, there are several anecdotal stories online of burns brought on by skin-applied apple cider vinegar.

Apple cider vinegar has been used to cure infections and moles, although there have been instances of skin burns as a result.
