Known for its tangy taste and potential health benefits, apple cider vinegar has become increasingly popular in cooking and as a supplement. While there is limited research on the health benefits of ACV, some smaller studies have shown that consuming it may support weight loss. A few studies focus specifically on vinegar's potential role in helping to reduce body fat. Other studies have correlated ACV intake with improved cholesterol levels and blood sugar control. The health benefits are associated with the "mother" content, a product of fermentation that contains the potentially beneficial bacteria, as well as the antioxidant and acetic acid contents.
Eliza Savage, MS, RD, CDN says, "Apple cider vinegar has many purported benefits, but it's always recommended to see what works for your individual body." It is important to note that raw, unpasteurized ACV may not be suitable for all, including pregnant women. It also can have potential negative side effects when consumed undiluted and in high amounts, including damage to tooth enamel, lowering potassium levels (especially when taken with certain medications), and gastrointestinal side effects like nausea and delayed gastric emptying.
ACV comes in powder, gummy, and liquid forms; however, we recommend the unpasteurized liquid, as it appears to be the only studied form backed by peer-reviewed research. When the ACV compounds are isolated in supplement pill, powder, or gummy form, the potential beneficial properties are less understood, and the actual ACV concentrations can vary greatly. Liquid ACV is also more versatile, as it can be added to dressings and sauces or to plain water for sipping. We researched a variety of options, considering taste, ingredients, and nutritional content, and selected only unpasteurized liquid forms.
