Pharax for Kids D3 5mcg Drops

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.

For babies, drops can be dispensed onto the breast, or added to breast milk or formula, and can also be dispensed on a sterile spoon.

Shake well for 10 seconds before each use to mix the bacteria culture with the oil. To dispense the drops, tilt the bottle gently and give by a spoon. Use 5 drops in the morning and 5 drops in the evening for 10 days.

Do not add drops to hot food, hot drinks or feed directly into the mouth from the bottle as this may reduce the quality of the product.
