The bottom line is, you don't need mega amounts of any vitamin or nutrient. Your body will end up flushing out what it can't use. Drinking water and eating a proper diet alone will keep you energized without the need for candy-coated supplements. The best way to nourish your body is to eat well and stick to the basics. Eat lots of fresh fruits and vegetables, whole grains, fish, lean meats and dairy products, and you'll provide your body with all the nutrients and energy it needs, without the extra sugar.
