What is Apple Cider Vinegar?

Apple cider vinegar's active component is acetic acid. Small human trials show that taking vinegar before a carbohydrate meal can meaningfully blunt the post-meal blood sugar and insulin spike, and some studies report modest improvements in fasting glucose and waist circumference over weeks. The effect is real but moderate, so it is best viewed as a small lever alongside diet. Liquid vinegar should always be diluted to protect tooth enamel and the esophagus, while capsules avoid the acidity and standardize the dose. With the mother is a marketing point, not a proven advantage. Around 1 to 2 tablespoons, or a 500 to 1000 mg capsule, before meals is typical.
