The Oveallgo SugarFixed Ultrasonic Liquefaction Hand Strap is designed to stimulate specific acupressure points on the wrist that are believed to regulate blood sugar levels. According to traditional medicine, these acupressure points are connected to the pancreas, liver, and spleen, which play a crucial role in blood sugar regulation. The Oveallgo SugarFixed Ultrasonic Liquefaction Hand Strap also emits negative ions that are believed to help boost insulin and improve overall metabolic function. These ions neutralize free radicals in the body and promote better circulation, which helps the body to function more efficiently. When the band is worn, it applies gentle pressure to these acupressure points and releases negative ions, which triggers the release of natural endorphins and neurotransmitters in the body. These substances help to balance the body's energy flow and activate the body's natural healing processes. The iONix Sugar Down AcuBand also works by stimulating the vagus nerve, which is a long nerve that connects the brain to the rest of the body. The vagus nerve plays a crucial role in regulating various bodily functions, including digestion, heart rate, and blood sugar levels. By stimulating the vagus nerve, it helps to regulate blood sugar levels and improve overall metabolic function. OUR GUARANTEE We are confident that we offer some of the best products on the market.
