Putting Pesky Germs to Rest

Zinc helps the immune system fight off intruders (the bad kind like viruses and bacteria....gross!)

Other ingredients: xylitol, mannitol, natural flavors, plant-based magnesium stearate, and monk fruit extract.

My picky little eater doesn't like the taste - what do I do?
First, make sure they aren't taking our Melty Tabs right after eating something sweet, like breakfast cereal, candy, or cookies (or that McDonald's sundae that your carpool partner got for them on the way home!)

Since our Melty Tabs are made with wholesome ingredients and Zero Sugar, their natural taste can be impacted if sweet things are eaten before (or if your child has an especially strong sweet tooth).

If you do have a serious picky eater and it doesn't seem to matter what they ate before, just send us a note at and we'll refund your money, no questions asked. We know the taste can be hit or miss with kids, so our Picky Eater money-back guarantee has your back!

Are these vegetarian and/or vegan-friendly?

Picky Eater Multi is 100% vegan-friendly.

Do these contain stevia?
Nope! Invincible Vitamin C does not contain stevia. We use only monk fruit and natural flavors to get our yummy taste just right.

How big is each tablet?
Our Invincible Vitamin C tablet is about the size of a small lima bean and easy for kids to just pop in their mouth (~13 mm in diameter). They go down extra smooth without water or swallowing big pills, thanks to our Melty Tab technology.

Is the product made on dedicated allergen-free equipment?
Renzo's are made in our family-owned facility that is free of peanuts, tree nuts, shellfish, and other common allergens. We can provide more information if you are interested in details on a specific allergy. Just send us a note at

How much mannitol and xylitol are in the product?
We use less than 0.75 grams per tablet (combined between these two natural ingredients) - just the right amount to make our Melty Tabs dissolve easily in tiny mouths.

How do you get so many vitamins and minerals into one serving?
Ahhh, we always love to hear from picky parents who actually read nutrition labels!

The short answer is there are decades of expertise that go into our Melty Tabs thanks to Dr. Rocca's experience as a pharmaceutical scientist. He knows how to do more with less, so all our formulas use the smallest amount of Other Ingredients possible.

We also purposefully don't use gummy technology because of the high sugar content and the stickiness that comes from using gelatin. This leaves more room for the good stuff - that way you can rest assured your kid (and your wallet) get the most from each serving.

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.

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!
