Vitamins provide energy.

Explanation:
Vitamins enable energy production but do not supply energy themselves. Energy in the body comes from the calories in carbohydrates, fats, and proteins, which are metabolized to yield ATP. Vitamins act as coenzymes or cofactors in the metabolic pathways that convert these macronutrients into usable energy. For example, several B vitamins function in glycolysis, the citric acid cycle, and oxidative phosphorylation, helping enzymes transfer electrons and carry out end steps efficiently. Because vitamins themselves contain no calories, they do not provide energy. That’s why the statement is false.
