Which of the following is NOT an example of modular products?

• A. Elemental formula
• B. Protein powders
• C. Carbohydrate powders
• D. Fat emulsion

Answer: (A)

Modular products are discrete macronutrient components you can add to a baseline formula to customize intake. They are separate ingredients that modify protein, carbohydrate, or fat delivery when mixed in. Protein powders, carbohydrate powders, and fat emulsions fit this idea because each provides a single macronutrient and is used to tailor the balance of nutrients.

An elemental formula, by contrast, is a complete product designed to be consumed as a ready-to-use formula. It’s fully hydrolyzed or semi-elemental and intended as a stand-alone option for patients with severely limited digestion or absorption, not as an add-on to adjust macronutrient content. Therefore, elemental formula is not a modular product.
