★★★★★
My kids use this immune defense gummies and they really like it. I see a difference when they take this compared to when they don't. They get less sick so to have a backup bottle of this is a must.i Got this Complimentary for reviewing purposes I know it's a bit pricey but better to have this they having my kids get sick.

★★★★★
Of all the products that I have tried similar to this, these drops are the best. My son enjoyed the flavor and the formulation seems to be highly effective for what it is advertised for. Excellent quality!

★★★★★
I noticed a huge improvement in the bowel movements of my child while taking Biostime Probiotics + HMO Prebiotic. She has been using the toilet smoothly and has way less tension when passing a bowl movement. She has less stomach issues and the only major change has been using this Biostime Probiotics/Prebiotic. I HIGHLY recommend this product to any parent with a child that has bowel movement issues. 10/10
