How can my kid take these?

These tiny Melty Tablets 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 Iron makes taking vitamins easy and fun, instead of a daily struggle.

Carbonyl Iron is equal to elemental Iron so 9mg of Carbonyl Iron in 1 Iron Strong Melty Tab equals 9mg of elemental Iron.

What is the conversion from Carbonyl Iron to Ferrous Sulfate?

9mg of Carbonyl Iron in 1 Iron Strong Melty Tab equals 45 mg of Ferrous Sulfate.

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

Our products are free from the “Big 8 Allergens” which includes: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 aforementioned ingredients.Regardless, 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 children under 2 take these vitamins?

Children under 2 can take our vitamins, but you would have to consult with your doctor for specific dosage requirements. This is because children under the age of 2 have more specific dietary requirements that should be recommended by their healthcare provider.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, Tree nuts, Peanuts, Gluten, Soy, Milk, and Eggs. However, we do not test for other fruits and vegetables. While it is unlikely 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 you child is sensitive to any ingredients we do not test for.
