"I truly believe in our mission of bringing better health to families."

"After learning about the massive amounts of sugar that were in typical kids multivitamins, I built a list of 198 Harvard and Yale nutritionists, pediatricians, and professors. From there, two of the top researchers at Harvard and Yale agreed to help! I explained my story to them, how I wanted to help parents, and what I found about the vitamin industry. And they were a huge help in creating this breakthrough in kids nutrition.

 That's why we’re so confident First Day will help you get the results you want. If within the first 45 days you find yourself not completely satisfied, we’ll give you your money back - no questions asked.**"

Picky Eaters Approval For First Day

As a parent, it’s important to me that my children receive the vitamins and nutrients they need, especially since they can be picky eaters. I initially chose the most convenient and affordable option by purchasing multivitamins from the grocery store. But that’s like giving them gummy bear candy. However, after trying numerous brands over the years, my kids did not agree on it.

After a lot of trial and error, First Day became the clear favorite for all three of my boys. They genuinely look forward to taking their vitamins each day and consistently agree that they taste great. As a parent, I appreciate that they’re getting valuable nutritional support from a product they actually enjoy. I’m so grateful I discovered First Day through an online advertisement—it has made maintaining a daily vitamin routine much easier for our family.

Amazing!

As a mama, I only want the best for my kid - and as a toddler, she’s picky and has some gaps. She LOOOOVES these more than anything and it’s never a battle
To get her to hoove them (usually it’s tears because she can only have two). A must for a happy healthy kiddo’!

A Fantastic Toddler Vitamin!

We started the First Day toddler daily vitamin because, like many, our kiddo had dove headfirst into picky eating. Despite trying our hardest to introduce new foods and always keep fruits and veggies on hand, we just knew he wasn't getting enough of the nutrients and vitamins he could be. I grew up on Flintstones vitamins and still shiver at the memory of that taste and texture. The First Day gummies are infinitely better. The texture and taste are great - without having to be loaded with sugar or fake dyes. We also LOVE that they do the refillable jar versus sending a new jar every single time. We absolutely recommend it for any parent looking for a great multi.

Seems to help

My son doesn't get the best balanced diet being in a picky eating stage and I noticed we had a lot of "I angry" meltdowns during the day. Since starting these his mid and behavior have made a dramatic change and now it seems like it's more of a regular 3 year old outbursts that are usually resolved quickly and we get a lot more "I love you" and "you my best friend" children's from him. Definitely worth trying

The Best Kids’ Vitamins We’ve Tried

These vitamins have been a game changer for my daughter. Before she started taking them, it felt like she was constantly catching every cold that went around. Since adding them to her daily routine, I've noticed a huge improvement in her immune system. Instead of being sick all the time, she now only gets the occasional minor cold, and there have been long stretches where she hasn't been sick at all.

Of course, every child is different, but for us, the difference has been remarkable. She enjoys taking them, and I love knowing she's getting extra support for her overall health and immunity. I highly recommend these vitamins to any parent looking to help support their child’s immune system.

**We offer a 45-day satisfaction guarantee for returns. It covers 45 days starting from the day that you place an order and includes only the very first purchase of any product so that families can try our gummies - for any reason you aren't happy with your vitamins. Please note that we will refund up to $100 so that you can try up to 3 bottles of our gummies risk free. If you would like to order more than 3 bottles in your first order, we recommend that you ordering less so that your family can try them first. Thanks so much for your understanding!
