Does Apple Cider Vinegar Lower Blood Sugar?

Apple cider vinegar can modestly lower blood sugar levels when consumed before meals. Research shows ACV contains acetic acid, which may improve insulin sensitivity and slow carbohydrate absorption. A 2018 study found that consuming 2 tablespoons of ACV before bedtime reduced fasting blood glucose by 4-6% in people with type 2 diabetes. However, the effect is relatively small compared to prescription medications. The vinegar works best when taken 15-30 minutes before eating, diluted in water to prevent tooth enamel damage. While promising, ACV should complement, not replace, proven diabetes management strategies like medication, diet, and exercise.
