As I rested in bed early this morning listening to the radio, I can across a radio program that was clearly an advertorial. The speaker was taking about how you can have more energy if you buy a zillion different types of his brand of vitamins, amino acids, anti-oxidants, and other such nutritional supplements. Not once did the speaker mention that food is the source of energy. Food contains calories, and calories are the fuel you need to function.
Vitamins and supplements are just the spark plugs in your bodys engine. No amount of supplements will boost your energy if you skip breakfast, skimp on lunch, and plow through the day with inadequate gas in your tank. Yes, you do need vitamins to help convert the food into energy. But I rarely see debilitating vitamin deficencies in active people who are eating 2,000 to 3,000+ calories a day, including many fortified foods like energy bars and breakfast cereals that can be vitamin pills in themselves.
