Their shipping is super slow. It takes a month to arrive. I'm not happy at all.

The Kids Z-Stack vitamins are literally the best kids’ vitamins out there, and we’ve tried plenty! If you want to keep your kids healthy, these vitamins really work! My three children have been taking them for about three years now. I get the subscription, and it’s worth every penny. Each of my children had a minor cold maybe twice within the entire last school year. I’m talking two to three days of sniffles, nothing major that even required a doctor’s visit. My oldest son had seasonal allergies for years, but not anymore. We virtually never get sick anymore. Praise God!!! Thank you, Dr. Zelenko! Also, the mixed berry flavor is awesome! My kids love it and say it tastes like Skittles!

Excellent customer service! Grateful for the help and problem solving!

The zsleeep really makes a difference in my sleep!!! They are very responsive and helful
