Parents agree Renzo’s Iron Strong is #1:


“My son is Iron deficient. He tried Gummy Iron Vitamins and HATED THEM. We finally found these dissolve in your mouth tablets and he says he, "LOVES," them. HALLELUJAH!!!”

- D Schager ⭐⭐⭐⭐⭐

“My kid had some iron deficiency issues… When I found these things, she actually would eat them. No bribing or fighting her to take it was necessary. The last time we went to the doctor, her iron levels were normal. Yay! She’s 2 now and looks forward to taking her vitamins.”

- Ed Todd ⭐⭐⭐⭐⭐


“Our son has been anemic since birth…These changed his life! He loves them so much he asks for more. Also, they dissolve quickly and easily AND his lab results are finally normal! For the first time in his life! Thank you Renzo’s!”

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 because toddlers have specific dietary requirements, we recommend that you ask your doctor for specific dosage requirements.

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 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.
