B4 is a pharmacist-created vitamin supplement you drink before you drink alcohol. It is caffeine-free and specifically formulated with liver protectants, a powerful rehydration blend, antioxidants and amino acids.
Think of it as sunscreen for your liver™.
Take a can before your first drink, like putting on sunscreen before you go in the sun. And just like sunscreen, if you’re going to be out in the sun for a while, or keep drinking, have a second or third can to reapply. Even if you’ve already started drinking, you’ll still want to protect yourself with B4. Like sunscreen, you may burn a little but it’ll still help.
