It's What's Inside That Counts
No Sugar. No Gummy. No Compromises
As parents ourselves, we found a better way to nourish our kids without giving in to sugary gummies disguised as "healthy."
Our melty formulas use the magic of monk fruit, which has all the sweet charm and none of sugar's harm.
Picky Eater Money Back Guarantee
Kids can have ‘refined palates’'so we made it extra easy to give Renzo's a try.
If your kid doesn’t like our melty vitamins, we’ll refund your money, no questions asked!

Frequently Asked Questions
What is IMMUSE®?
IMMUSE® is the star player in Renzo's Roll Call Immunity. This clinically-researched postbiotic superhero ingredient has been carefully crafted to support your kid's immune health.* It has been shown to engage and activate plasmacytoid dendritic cells (pDCs), which are like the immune system's little cheerleaders, rallying the body's defenses. This amazing postbiotic doesn’t just help out on the surface—it supports your child's immune health at the cellular level, promoting year-round wellness.*
How does it support immunity?
IMMUSE® is all about giving your child's immune system a helping hand. It has demonstrated the ability to target and activate pDCs, the special cells that jumpstart an immune response. By getting these cells fired up, IMMUSE® helps support the immune system, giving your little one the health support needed to take on the day, every day.*
What sets Roll Call Immunity apart from other kids' immune support supplements, like Vitamin C?
What makes Roll Call Immunity stand out? It’s the postbiotic IMMUSE®! While Vitamin C is a fantastic ally for general immune support with its antioxidant perks, IMMUSE® dives deeper. It works at the cellular level to support the immune system’s natural defenders, providing a more complete approach.* Plus, Roll Call Immunity is specially formulated to support respiratory health, to help keep those little lungs happy and healthy.* It’s comprehensive immune support that can go beyond the benefits of Vitamin C alone.
What’s the difference between using Roll Call Immunity and a kid’s probiotic?
Roll Call Immunity and kids' probiotics both support your child’s health but in different ways. Probiotics are all about balancing the gut microbiome, which can have a knock-on effect on overall immune health. On the other hand, Roll Call Immunity, with its star ingredient IMMUSE®, is designed to support specialized immune cells. By helping to activate pDCs, it can support sustained immune health.* So, while probiotics may be great for general gut health, Roll Call Immunity offers an additional way to support your child's immune health.*
Can kids take multiple Renzo’s vitamins together?
- They sure can! We understand all kid’s health needs are different. We recommend taking these one at a time so each flavor can be enjoyed on its own.
Pro tip: We recommend you take these without milk or dairy products as these can inhibit iron absorption.
My kids are younger than 2 years old, can they still take them?
Although we've had instances in which kids as young as 16 months take our Melty Tabs, we still recommend asking your health care provider if Renzo's is safe for your toddlers.
