Vitamin D contributes to the normal function of the immune system in children, making these drops a simple way to help maintain your child’s natural defences as they grow.

Each serving provides 200% of the daily recommended vitamin D, in a liquid format that’s easy to use and gentle on little tummies. The live cultures are carefully selected to reach the gut alive, where they can complement your child’s natural microbiome. Just 10 drops a day (5 in the morning, 5 at night) fit easily into your family’s routine, supporting your child’s wellbeing every step of the way.

BioGaia supplements contain Lactobacillus reuteri, a probiotic strain originally found in the human body. Because it naturally evolved in humans, it may work in closer harmony with the gut microbiome. The exclusive DSM 17938 strain in this formula is shown to survive stomach acid and reach the gut alive. It’s also been studied in collaboration with respected research centres, including the Karolinska Institute (Sweden), Texas Children’s Hospital (USA), and the University Hospitals of Bari and Turin (Italy). This global scientific collaboration is one reason why BioGaia is trusted by parents around the world. It’s a probiotic backed by science, made to support children’s gut health.

BioGaia is a Swedish health company that has been pioneering probiotic research since 1990. With over 200,000 hours of scientific work behind every product, their formulas feature patented strains of Lactobacillus reuteri—one of the world’s most studied probiotics. Backed by clinical trials and a commitment to gut health, BioGaia creates trusted supplements for both children and adults.
