"I couldn’t be happier with the Biostime Kids Multivitamin Gummies with Probiotics & 11 Essential Vitamins! My 7-year-old son absolutely loves them, especially the delicious strawberry flavor. It’s always a struggle to get kids to enjoy taking vitamins, but these gummies make it so easy. On top of that, these gummies offer a fantastic blend of both probiotics and essential vitamins, which help keep my son healthy and thriving. It’s a great way to ensure he’s getting the extra boost he needs every day.I highly recommend these gummies to parents, especially those with kids who have allergies. They’re tasty, safe, and packed with all the goodness kids need!"

“This has become a great part of our routine. The packets are single serve and dissolve quickly in hot or cold. There is no grittiness and my daughter has no problem drinking it. I haven't tried food yet but seeing out it dissolves quickly in her water, orange and/milk I'm going to try it out with some oatmeal. This is a good proactive step as the weather is changing from summer to fall.”

“This has made such an immense difference in my baby’s bowel movements and has become a staple in our home. Especially after starting solids, our exclusively breast feed baby was just so constipated and gassy. We tried everything, until we found this golden supplement. She is so much happier.”
