Primary Function: Advanced B Complex uses the methylated vitamin form to ensure absorption and support energy, metabolism and more. Your body needs B vitamins to turn carbs, fats and proteins into energy. Stress, age, and refined sugars all steal these nutrients from the body. And more than 50% of people have one of the risk factors that creates an increased need for B vitamins. Advanced B Complex combines the active forms of 9 different B vitamins, so your body can skip the step of converting these vitamins and directly access the health benefits these essential nutrients offer. You'll feel the difference, guaranteed!
