A good performance multivitamin combines vitamins, minerals, and additional workout-support nutrients. Your body needs more than proteins, carbs and fats. You need micronutrients in vital amounts to cover gaps in your diet. Iron, zinc, vitamin C, vitamin B and others are all important to good health. Vitamins and minerals play critical roles in a variety of biological functions. Athletes and active individuals typically need more vitamins and minerals than sedentary individuals. It can be especially hard to eat perfectly in college, so let a multivitamin take stress away from you.
