Frequently Asked Questions
Why does my child need Iron?
Iron is the most important mineral in your child’s nutrition. Iron produces hemoglobin, the protein found in red blood cells that distributes oxygen to the rest of the body. Because of hemoglobin, your child is able to produce healthy red blood cells to support their growing muscles and tissues with the oxygen they need.
If your doctor informs you that your child has an Iron deficiency, this supplement ensures they’ll receive the daily value needed. Plus it tastes delicious, unlike most liquid metal-tasting supplements!
Why does this product have Vitamin C?
Vitamin C helps the body absorb Iron more effectively. Iron is super important for boosting the immune system and keeping kids’ health in tip-top shape. Plus, the Oh-Oh- Oh Orange taste is full of yummy Vitamin C kids will love.
What is carbonyl iron, and what makes it special?
Carbonyl iron is a highly purified form of elemental iron that is known for its safety and gentle effects on the stomach, making it an excellent choice for iron supplementation, especially for kids.
Unlike other forms of iron, carbonyl iron slowly dissolves in the digestive system, which helps reduce the risk of stomach upset and be better tolerated.*
Plus, Renzo’s Iron Strong Melty Tabs mean no messy liquid that can stain your couch and your kids’ teeth, win!
How much iron is in each Melty Tab?
Each Melty Tab of Renzo’s Iron Strong contains 9 mg of carbonyl iron (in other words, 9 mg of elemental iron). This would be equivalent to 45 mg of ferrous sulfate.
Carbonyl iron is equivalent to 100% elemental iron, whereas ferrous sulfate is equivalent to only 20% elemental iron. Carbonyl iron is safer, more gentle on the tummy, and absorbs better than ferrous sulfate.
Should Renzo’s Iron Strong be taken on an empty stomach?
For best results, we recommend taking these on an empty stomach. Optimal iron absorption can potentially be limited by the presence of calcium or dairy, so it'd be best to avoid combining any calcium-fortified foods with Iron Strong.
