Vitamins Provide Energy?

• A. True
• B. False
• C. Sometimes
• D. Not specified

Answer: (B)

Vitamins do not provide energy themselves. They are micronutrients that enable energy production by acting as cofactors and coenzymes in the body's metabolic reactions. Calories come from macronutrients—carbohydrates, fats, and proteins—and vitamins have no calories, so they don’t directly supply energy.

Many B vitamins are essential for the enzymes that release energy from nutrients. For example, thiamin, riboflavin, niacin, and others participate in glycolysis, the citric acid cycle, and the electron transport chain. Without these vitamins, the body’s ability to extract energy from food can be impaired, even though the vitamins themselves don’t add calories.

So, the statement is false: vitamins support energy production, but they do not provide energy themselves.
