Culturelle Kids Grow + Thrive Packets are a simple and effective way to promote your child's healthy digestion, immune health and overall development. In fact, more pediatricians choose Culturelle probiotics for their own children than any other brand.± That's because they know that Culturelle probiotics harness the power of Lactobacillus rhamnosus GG (LGG), the #1 clinically studied probiotic strain. When taken daily, these convenient packets are formulated with proven probiotics and Vitamin D to work around the clock to help keep your child's digestion and immune system going strong, plus HMOs. To top it off, your kids won't even know they're taking a probiotic! That's because these packets are easily mixed in with their favorite cold or room-temperature foods like applesauce or yogurt.
