What you can expect
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!!!"

Peace of Mind
"My granddaughter asks for her vitamins every morning. Makes me happy knowing she’s getting a lot of good nutrients without the sugar that comes in the traditional gummy vitamins!!"

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!"
