One of my kids only eats beige foods (carbs and cheese) so giving these to him not only helps the mom-guilt, but ensures he's getting actual healthy nutrients in him! I've already noticed an air of calm in the house.

I purchased these about 3 weeks ago and WOW is all I can say. Already my household is different and the change I see in my daughter is absolutely amazing!!!!

It's been such a struggle finding a vitamin my 3 picky eaters won't fight me on taking daily that isn't chock-full of sugar & artificial junk. I can confidently give them these & feel good that they're getting nutrition in when they're so picky about everything else. Highly recommend First Day!
Aynsley B.Hello growth spurts!
After taking Women’s Supercharge for three months I knew I had to share these with my kids! First, they taste so good my kids ask for them every morning. I feel confident that all my kids have the nutrition their growing bodies need. Thank you First Day!
Nicole H.Clean vitamins for kids and me!
They are delicious but also not loaded with sugar like other gummy options, thankfully! I feel great taking my vitamin with the kids every morning, it's become a fun part of our morning routine before they head off to school.

Where have these been!?
"I struggled to find vitamins for not only myself but ones my husband would actually take. Then I heard about First Day and initially I was kind of skeptical because a lot of vitamins say that they’re all natural. My husband also never had taken vitamins a day in his life.
So I decided to give first day a try. Not only did they taste great but they actually are all natural. No crazy hidden ingredients and bonus my husband actually takes his every day as well. Thank you for creating first day!!!"

Picky Eaters Approved!
"All 3 of my picky eaters happily eat these daily and actually have made the comments that they wish they could eat the whole bag bc of how delicious they taste.
It's been such a struggle finding a vitamin they won't fight me on taking daily that isn't chock-full of sugar & artificial junk.
I can confidently give them these & feel good that they're getting nutrition in when they're so picky about everything else healthy I try to give them. Highly recommend First Day!"
