Buying Guide

CFU count and strain diversity

Look for products that list total CFU at time of manufacture and multiple Lactobacillus strains, including L. acidophilus, for broader gut coverage

Prebiotics and formulation

Choose formulas that include organic prebiotic fibers or delayed-release capsules when targeting colon delivery and sustained activity

Serving size and servings per bottle

Compare CFU per serving and total servings to evaluate real per-dose value rather than only list CFU per bottle

Allergen and dietary needs

Check labels for dairy, soy, gluten, and vegan/vegetarian status if you have sensitivities or prefer plant-based formulations

Intended user and form factor

Match product form—capsule, chewable, or veggie cap—and kid-specific formulations to the user to improve adherence and safety
