Love this powder!

I love the ingredients in this dual defense powder! I mix it in with any food or drink and my daughter can't taste it at all. The packs are super easy and convenient, and I love knowing that I'm helping to keep her immune system strong and protect her from seasonal colds. Would recommend this!!

Works for my son

Biostime Dual Defense works for my son. I've been mixing it into his morning juice, and he drinks it without hesitation. Lots of other kids in his class have already come down with colds this year, but my son has not. I'd say that's a good sign Biostime is working and boosting his immune system.

Great product for immune and gut health

I've been giving Biostime Dual Defense to my kids, and I'm so happy with it! It's easy to mix into their drinks, and they take it without any problem. I've noticed they've been getting sick less often and seem to have better digestion. I'll definitely keep using it every day.
