Keto + ACV (Apple Cider Vinegar) gummies are popular supplements that combine apple cider vinegar with ingredients designed to support a ketogenic lifestyle. They are primarily marketed for appetite suppression, metabolism support, and energy, though experts emphasize they work best as a complement to diet and exercise.The acetic acid in ACV has been linked to increased feelings of fullness (satiety), which may help curb cravings for sugary snacks and reduce daily calorie intake.Some studies suggest that vinegar can help reduce blood sugar spikes after a meal, leading to more stable energy levels throughout the day.
