- Vitamins function as catalysts because they help the body use energy nutrients without containing energy themselves.
- This catalytic action enables the body to break down carbohydrates, fats and proteins into usable energy during exercise.
- B vitamins particularly assist converting carbohydrates to energy, which is essential for the aerobic system as carbohydrates are its main fuel source.
- Therefore, adequate vitamin intake ensures efficient energy production by facilitating the breakdown of food fuels for active people.
