What are essential vitamins?

What are essential vitamins?

• A. Vitamins needed from the diet.
• B. Vitamins produced by the body in sufficient amounts.
• C. Minerals required in amounts greater than 100 mg/day.
• D. Fats that provide energy.

Answer: (A)

Vitamins are essential when the body cannot make them in enough amounts, so they must be provided by the diet to prevent deficiency and support normal metabolism. This is why the correct choice is that essential vitamins are vitamins needed from the diet. While some vitamins can be synthesized to some extent (for example, vitamin D can be made in the skin with sunlight), the amounts produced are not reliably sufficient for everyone, so dietary intake remains necessary. The other options mix up nutrient categories: minerals are inorganic nutrients, not vitamins; fats are a type of macronutrient that provides energy, not vitamins.
