Apple cider vinegar (ACV) is a vinegar made from fermented apple juice. Like other vinegars, it is produced in a two-step fermentation process. First, yeast ferments the sugars in apple juice into alcohol. Second, bacteria (Acetobacter species) convert the alcohol into acetic acid, which is the main active component of vinegar. ACV contains 5-6% acetic acid, along with water and trace amounts of other acids like malic acid, and a small number of minerals and vitamins, though not in significant amounts (Examine.com).
Historically, vinegar has been used for various purposes, including food preservation, cleaning, and traditional medicine. Its use as a health supplement has gained popularity over recent decades, with proponents suggesting a range of benefits from weight management to blood sugar control. Despite its widespread use, many of the purported health benefits require more rigorous scientific investigation to establish definitive efficacy (NIH ODS).
