Which characteristic describes standard polymeric formulas?

• A. They require lactose-free formulations
• B. They provide 1-2 kcal per mL and are generally less expensive
• C. They are only used for patients with immune support needs
• D. They are exclusively for pediatric patients

Answer: (B)

Standard polymeric formulas use intact proteins, carbohydrates, and fats, so they rely on a functioning digestive system to break down and absorb nutrients. Because they’re made from conventional ingredients rather than specialized or hydrolyzed components, they usually deliver about 1 kcal per mL (with some high-energy versions reaching up to 2 kcal per mL) and tend to be less expensive than more specialized formulas. This combination—maintaining typical energy density and lower cost—makes them a common first-line choice for adults and children who don’t have significant malabsorption or immune support needs. They aren’t restricted to lactose-free products or to pediatric patients, and lactose content varies by product, so lactose-free is not a defining trait.
