Apple cider vinegar is a type of vinegar made by the fermentation of apple cider. During the fermentation process, sugar in the apple cider is broken down by bacteria and yeast into alcohol and then into vinegar. Like other types of vinegar, apple cider vinegar contains acetic acid and it also contains some lactic, citric and malic acids.
Health Benefits of Apple Cider Vinegar:
To date, few studies have tested the health effects of apple cider vinegar. Here's a look at some key findings from the available research:
Some preliminary research suggests that vinegar (both apple cider vinegar and other types) may benefit people with diabetes. For example, in a 2007 study published in Diabetes Care, researchers found that type 2 diabetes patients who consumed two tablespoons of apple cider vinegar at bedtime showed favorable changes in blood sugar levels the following morning.
In an animal-based study published in the Pakistan Journal of Biological Sciences, scientists found that diabetic rats fed an apple-cider-vinegar-enhanced diet for four weeks experienced an increase in HDL ("good") cholesterol (as well as a reduction in their levels of triglycerides, a type of harmful blood fat).

2) Weight Loss
There is limited scientific support for the claim that apple cider vinegar can promote weight loss. However, one small study (published in Bioscience, Biotechnology, and Biochemistry in 2009) found that obese people who consumed acetic acid daily for 12 weeks experienced significant decreases in body weight, abdominal fat, waist circumference, and triglycerides. In tests on mice, another 2009 study (published in the Journal of Agricultural and Food Chemistry) found that acetic acid may help prevent the buildup of body fat and certain liver fats. It's unknown whether these studies tested the use of acetic acid derived from apple cider vinegar or from other vinegar types.Learn more about apple cider vinegar for weight loss and also check out how to lose weight naturally and learn about 15 popular weight loss supplements.
3) High Blood Pressure
Acetic acid may help lower high blood pressure, according to an animal-based study published in Bioscience, Biotechnology, and Biochemistry in 2001. Again, it's unknown whether this study tested the use of acetic acid derived from apple cider vinegar or from another vinegar type.

4) High Cholesterol
Published in the British Journal of Nutrition, a 2006 study found that rats fed acetic acid for 19 days had a significant reduction in total cholesterol and triglyceride levels.

When using apple cider vinegar to treat acne, some alternative practitioners recommend mixing one part apple cider vinegar with three parts water. The solution is then dabbed onto the pimple. Since there have been case reports of skin damage and burns from using full-strength vinegar on the face, it's important to take caution when using this remedy.

7) Alkaline Acid Balance
Some alternative practitioners recommend using apple cider vinegar to restore alkaline acid balance. The theory behind the alkaline diet is that our blood is slightly alkaline (with a normal pH level of between 7.35 and 7.45) and that our diet should reflect this pH level. Proponents of the alkaline-acid theory believe that a diet high in acid-producing foods leads to lack of energy, excessive mucous production, infections, anxiety, irritability, headache, sore throat, nasal and sinus congestion, allergic reactions, and increased risk of conditions such as arthritis and gout.
Despite being an acidic solution, some proponents of apple cider vinegar believe it has an alkalinizing effect on the body. As such, they recommend one to two teaspoons of apple cider vinegar in water as a daily health tonic. Although this is a popular remedy, its effectiveness hasn't been researched.
Other Common Uses For Apple Cider Vinegar:
Proponents claim that apple cider vinegar can also help with the following health conditions:
Side Effects and Safety Concerns:
Undiluted apple cider vinegar, in liquid or pill form, may damage the esophagus and other parts of the digestive tract. Apple cider vinegar drinks may damage tooth enamel if sipped.
One case report linked excessive apple cider vinegar consumption with low blood potassium levels (hypokalemia) and low bone mineral density. People with osteoporosis, low potassium levels, and those taking potassium-lowering medications should use caution.
People with allergies to apples should avoid apple cider vinegar.
Vinegar applied to the skin may cause burns and scarring.
Excessive doses of apple cider vinegar have been found to cause damage to the stomach, duodenum, and liver in animals.
Possible Drug Interactions:
Theoretically, prolonged use of apple cider vinegar could lead to lower potassium levels, which could increase the risk of toxicity of cardiac glycoside drugs such as Lanoxin (digoxin), insulin, laxatives, and diuretics such as Lasix (furosemide).
Because apple cider vinegar may affect blood glucose and insulin levels, it could theoretically have an additive effect if combined with diabetes medications. Apple cider vinegar may also lower blood pressure, so it may have an additive effect if combined with high blood pressure medications.
