Our melty tablets' terrific taste makes taking vitamins an easy and enchanting experience for kids.
The calcium chewable that’s tastier and healthier
Made for kids, Hercules Calcium is free from gummy gunk and loaded with great taste.
Does your kid need to chew-chew-choose more calcium?
Kids need calcium to build strong bones and teeth. It’s a hero nutrient for healthy muscles and nerves, too.
But calcium alone can’t complete its health mission without vitamin D and vitamin K2.
This calcium chewable for kids delivers an ideal ratio of all three nutrients in a chewable tab that’s grape-alicious good!

Discover the fantastic sugar-free formula that gets calcium right where kids need it
It takes a very special calcium chewable to build the strongest bones and teeth.
First, you need a high-quality form of calcium that’s gentle on the tummy. (We used tribasic calcium phosphate.)
You also need vitamin D to help your body absorb calcium and vitamin K2 to direct calcium to the right places.
And most importantly, a formula that's nutritious and delicious without all the sugar found in gummies.
Did you know one gummy vitamin has as much sugar per weight as a cookie?
That never sat right with us.
So we went on a quest for a healthy alternative and found the magic of monk fruit.
It has all the sweet charm and none of sugar's harm.
Finally, calcium chewables with vitamin D you can feel good about giving to kids!

Questions Parents Ask About Renzo’s Hercules Calcium
How do I know if my child needs a calcium and vitamin D supplement?
If your child doesn’t eat several calcium-rich foods daily, they may need a calcium supplement to build strong bones, teeth, and muscles.
To meet a child’s requirements for calcium (and complementary vitamin D), they’ll need 2-4 servings of dairy daily, depending on their age.
Have a kid who doesn’t eat dairy? Look at how often they eat calcium-fortified foods and vegan sources of calcium (like spinach).
Many kids don’t meet the Recommended Dietary Allowance of calcium and vitamin D. That’s why Renzo’s calcium chewables exist. Hercules Calcium makes it easy to top up your kid’s intake of calcium every day.
How much vitamin K2 should my child get per day?
Health officials have defined “adequate intake” amounts for vitamin K (but not “daily value”). Children ages 3-18 need between 30 and 75 mcg of vitamin K daily.
What do you use instead of sugar to sweeten Renzo’s tabs?
We use mannitol and xylitol. These plant-derived ingredients and natural sugar substitutes give each tab a sweet taste without harmful sugar. Dentists (and tooth fairies) love xylitol because it helps strengthen teeth!
Are these calcium chewables vegan?
Yes, Hercules Calcium is made with vegan vitamin D, so you can feel good knowing no sheep were harmed in the making of these chewables.
Are these chewables or melty vitamins?
Renzo’s tabs can be easily chewed, and they also melt in your mouth. It takes just a few seconds for the tabs to melt, releasing the sugar-free sweetness and fun fruit flavors.
What if my child is too young to chew a calcium supplement?
Your child doesn’t have to chew to get the goodness from Hercules Calcium. As soon as each tablet comes in contact with saliva, it instantly dissolves!
Why should I choose a chewable that dissolves?
Nutrients that are dissolved are more absorbable. Little bodies don’t have to break down hard tablets because these tabs melt on contact with saliva.
Why are calcium and vitamin gummies unhealthy?
Sugar isn’t great for growing bodies, and it’s definitely a no-no for teeth. (Especially when that sugar sticks to teeth because it’s in a gummy.) Gummies are also a choking hazard for toddlers.
That’s why we made Renzo’s tabs that fully melt in the mouth, with no sugar to leave traces on the teeth.
Can my child under 2 take these?
Children under 2 can take this supplement, but because toddlers have specific dietary requirements, we recommend that you ask your doctor for specific dosage requirements.
As a tip, these calcium tabs can be chewed, swallowed, or dissolved in the mouth or water, so you have a wide variety of ways to give the vitamin to your toddler!
