Lactose
Lactose is the carbohydrate found in breast milk, which makes Lactose-based formulas much closer to breast milk than alternatives. All infants produce the lactase enzyme, allowing them to easily digest and absorb Lactose.
Lactose also has a far lower glycemic index than processed refined sugars, aids in the absorption of calcium, helps the growth of beneficial gut bacteria, and more.
In short, choosing a Lactose-based formula is probably the most important step in finding the best formula out there. As you read the ingredients, keep in mind that lactose is the main ingredient in cow’s milk, and may appear as “organic cow’s milk” or “organic skimmed milk” in ingredient lists. Lactose-based formulas are typically manufactured in Europe.
