Chase and Rhonda are studying for the nutrition quiz on vitamins. Over the semester break Chase started taking several dietary supplements and a water-soluble multi-vitamin to help improve his energy level and nutrient status. Rhonda has been a vegan (consumes no animal products or by-products) for several months. As they study for their quiz they explore natural sources of the essential
vitamins. Chase believes that Rhonda should be taking a multi-vitamin supplement because of her vegetarian lifestyle, but Rhonda believes that Chase is likely overdosing on some of the vitamin supplements. Help them study for their quiz and determine who is right about their need for dietary supplements. Will Chase's multi-vitamin provide him with a greater level of energy?

C) Maybe; although vitamins do not provide calories to the body, they do act as coenzymes that release energy from carbohydrates, protein, and fat. D) No; although vitamins contain calories, the body is not able to digest them and therefore they do not improve energy level in the body.
