How We Build Our Products

Every product we make is held to the same standard.

Built on published research

We formulate around real clinical studies, not whatever ingredient is trending this year.

Dosed for kids, not adults

Our formulas are built around what a growing child's body actually needs — not an adult vitamin scaled down.

A guarantee that means it

60 days to decide if it's working. If it's not, you get your money back — no hoops.

"My daughter used to be the shortest in her friendship group by a mile, however she's making good progress. I'll continue to monitor over the next few months and will most likely repurchase."

Frequently Asked Questions

What makes Mortaine's supplements different?
We formulate around published clinical research rather than industry trends, and we dose specifically for growing children rather than scaling down an adult vitamin. When the research moves forward, we update our formulas rather than sticking with what's familiar.
Is this safe for my child?
Yes. Every ingredient we use has a track record of safe use, and each formula is dosed specifically for the age group it's designed for — not adapted from an adult product. As with any supplement, we recommend consulting your child's pediatrician before starting, especially if they take other medications or have an existing health condition.
When will I see results?
Growth is gradual and individual, and results vary. Most parents give it a few months of consistent use to properly evaluate progress, which is part of why we offer a 60-day guarantee.
What's your refund policy?
If you're not happy with your purchase, you can request a full refund within 60 days of your order — no questions asked.
