Background

Apple cider vinegar (ACV) is prepared by pulverizing apples into a slurry of juice and pulp and then adding yeast and sugars.
Reports of the healing properties of apple cider vinegar date to 3300 BC. In 400 BC, Hippocrates supposedly used apple cider vinegar as a healing elixir, an antibiotic, and for general health. Samurai warriors purportedly used a vinegar tonic for strength and power. U.S. Civil War soldiers used a vinegar solution to prevent gastric upset and as a treatment for pneumonia and scurvy.
Apple cider vinegar has been used alone and in combination with other agents for many health conditions. Anecdotally, ancient Egyptians used apple cider vinegar for weight loss. During the diet "craze" of the 1970s, proponents suggested that a combination of apple cider, kelp, vitamin B6, and lecithin could "trick" the body's metabolism into burning fat faster. Claims of preventing viral and bacterial infections, as well as allergic reactions to pollen, dander, and dust, stem from the proposed ability of apple cider vinegar to prevent alkalinization of the body. However, there is not enough scientific evidence to form a clear conclusion about the efficacy or safety of apple cider vinegar for any health condition.
There may be long-term risks associated with the acidity of apple cider vinegar, including low blood potassium levels (hypokalemia) or diminished bone mineral density.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

Adults (over 18 years old)
No specific doses are supported by well-designed clinical trials. In general, 2 teaspoons of cider vinegar have been taken in 1 cup water three times daily. Also, 285-milligram tablets have been taken with meals. Topical and rectal preparations have also been used but safety is unclear.

Safety

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Interactions

Interactions with Drugs
Note: Theoretical interactions are based on potential pH altering effects of apple cider vinegar. The degree to which apple cider vinegar affects blood pH is currently not established.
Theoretically, long-term oral use of apple cider vinegar can decrease potassium levels, increasing the risk of toxicity of cardiac glycoside drugs such as digoxin (Lanoxin?). Long-term use may also add to the potassium-lowering effects of insulin, laxatives, and diuretics such as furosemide (Lasix?).
