Tried So Many!

I have tried so many vitamins for my kids but they always hate the taste or texture of them! These are so delicious AND help support their immune system! SO happy with this product!

I have a 5 year old that is a very picky eater. Knowing he’s getting vitamins from First Day makes me feel much better about his appetite!! He reminds me everyday and says they taste like candy! Happy we found them!!

My Kids Love Them!

I ordered the Teen multivitamin for my 3 teens and to my surprise all three LOVE them! With other brands I had to harp on them to take their vitamins but since I switched over to First Day they take them without being asked! WIN WIN! 🏅 They taste great and the packaging is cute! Love them!!
