The Hangover Prevention patch contains a unique balance of vitamins, minerals, antioxidants and herbs that naturally help your body process alcohol and help prevent hangovers. In addition always drink at least 8 ounces of pure water before bedtime. One Package contains 30 Individual patches. Our Hangover Patch helps to prevent some of the unwanted side effects of drinking so that you look and feel your best the next day. Despite our concerted efforts to drink responsibly, it’s easy to underestimate how much a few glasses of wine (or something stronger) can have on our body. But our proprietary blend of Milk Thistle Extract, Ginger Root, Alpha Lipoic Acid & Pantethine can help. By wearing our hangover prevention patch before you start drinking, you can minimize the tiredness, nausea, and headaches that many people suffer with.
