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.

Frequently Asked Questions
What makes Renzo’s Invincible Vitamin C different from other Vitamin C supplements?
Renzo’s Invincible Vitamin C is not your average immune booster! We get our vitamin C from Acerola cherries, a superfruit packed with natural goodness, and ascorbic acid. We also add Zinc for extra immune support and Elderberry, a time-tested ingredient for wellness. And the best part? Our yummy, sugar-free Melty Tabs make it easy (and fun) for kids to take—no artificial stuff, no struggles!
How do Vitamin C, Zinc, and Elderberry work together to support the immune system?
Vitamin C, Zinc, and Elderberry work together like a dream team to keep your little one’s immune system strong and ready!
- Vitamin C fuels white blood cells, helping the body respond quickly to everyday challenges.
- Zinc powers up T-cells (white blood cells that help the immune system responses) and natural killer cells, giving the immune system the tools it needs to fight back.
- Elderberry brings extra antioxidant support, helping to neutralize free radicals and keep kids feeling their best—especially during seasonal changes.
Can this supplement be taken daily, or is it only for seasonal support?
This supplement may be taken daily to support overall wellness and immune health on an ongoing basis. If you have specific health concerns, we recommend consulting a healthcare professional."
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.
