Pop a Multi
While you’re downing that water (or your smoothie) take a multivitamin, too. Alcohol flushes certain nutrients, like vitamin B-12 and folate, out of your system. Those vitamins not only support blood flow (essential for flushing toxins from your liver) but also boost your metabolism and your energy, something that’s definitely lacking when you’re nursing a hangover. In addition to vitamins, a multivitamin supplies other essential nutrients you need to get back to normal.
