Got Questions?

We’ve Got Answers.

My child has a food allergy. Is Renzo’s right for me?

Our products are free from the “Big 8 Allergens” which include:Fish, Shellfish (crustacean), Tree nuts (walnut, pecan, almond), Peanuts, Gluten (wheat, rye, barley), Soy, Milk (Beta-lactoglobulin dairy and casein), and Eggs.Our products are tested in 3rd Party Labs which follow FDA guidelines when checking for any traces of the big 8 allergens!We always advise consulting with a healthcare professional before use of any dietary supplement, along with careful monitoring in the case of treating allergic reactions.

Can my child under 2 take these?

Children under 2 can take our vitamins, but because toddlers have specific dietary requirements, we recommend that you ask your doctor for specific dosage requirements.As a tip, the vitamins can be chewed, swallowed or dissolved in the mouth or in water so you have a wide variety of ways to give the vitamin to your toddler!

What ingredients are in your natural flavors?

It is possible for our natural flavors to contain trace amounts of other fruits and vegetables. We test our products to make sure there are no traces of the Big 8 allergens: Fish, Shellfish (crustacean), Tree nuts (walnut, pecan, almond), Peanuts, Gluten (wheat, rye, barley), Soy, Milk (Beta-lactoglobulin dairy and casein), and Eggs. However, we do not test for other fruits and vegetables.While it is unlikely that our products would contain traces of other fruits, vegetables or other ingredients, we would highly recommend checking with a healthcare professional before using Renzo’s if your child is sensitive to any ingredients we do not test for.

How can my kid take these?

The best way to take these vitamins is to let them dissolve in the mouth! However, these tiny Melty Tabs can be dissolved in the mouth, chewed, swallowed or dissolved in water or juice (orange juice is a Renzo’s mom favorite)! Multiple ways to take makes taking vitamins easy and fun, instead of a daily struggle.

What vitamins are good for ADHD or sensory disorders?

Many Mommas have told us like Picky Eater Multi or Bright & Brainy B6.

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.

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!
