Our bodies require additional nutritional factors to feel energized then carbohydrates, fats and proteins (the caloric nutrients). We often can have sufficient caloric nutrients and still feel sluggish. We call these the non-caloric "nutrient" components that keep us well are called "energizers". These dietary welltrients address different organ systems and feed the cells the needed nutrients. They are not drugs, stimulants or anything that shakes the body up.
