Product Description

When seasons change and sniffles start to show up, Biostime Dual Defense helps support your child’s natural defenses from the inside out. This daily probiotic + prebiotic supplement is specially formulated for babies and kids 6 months and older to support nasal and respiratory wellness, while also nurturing the gut where much of the immune system lives.*

Each single-serving sachet combines 5 billion CFU from clinically studied probiotic strains with 2’-FL HMO prebiotic — a specialized prebiotic structurally similar to one found in breast milk — to help nourish a healthy gut microbiome and support everyday immune health.*

Not to be taken on the same day as breastmilk or other products containing 2’-FL HMO±, such as fortified infant formula. Mix until contents are completely dissolved. Do not mix with hot or warm liquids or food.


Ages
