Very impressed!

I added a packet into my daughter's yogurt in the morning and definitely noticed a difference with her sniffles. While other kids in her class all came down with colds, she maintained her health and her sniffles went away. She couldn't taste anything either! I think these make a great addition to our household!

Good product to support immune

Thanks Biostime for a free sample of dual defense prebiotics. I give it to my kids on daily basis, this has become a great part of our daily routine. I love the single serving packets and it is so easy to use. I dissolve it in a glass of milk or juice. It doesn't have a bad taste. This supplement is great for supplementing my kids immune and respiratory health during cold and flu season.

"Biostime Dual Defense: Easy Use, Real Benefits

Biostime Dual Defense Powder was super easy to mix and way gentler on my stomach than a lot of other probiotic supplements I've tried for my kids. I liked that it's designed to support both immune system and respiratory health, which really helps during those sniffly seasons. The single-serve sachets are perfect for busy mornings and travel, so I can see myself picking up another box. I'd happily tell other parents about it because of the science-backed ingredients and noticeable benefi #freeproduct.
