Backed by experts, we combed through 35,000+ pediatric studies.
We rely on real fruit like strawberries & oranges.
Every gummy is packed with antioxidants and phytonutrients.
Speech and language delays often trace back to a folate gap, one of the most common nutrient deficiencies..
💡 Did You Know?
Up to 40% of toddlers carry a gene variant that makes synthetic folic acid nearly impossible for their body to use. First Day uses methylfolate instead — an active form bodies can actually absorb.
Mood swings and irritability usually point to a B6 deficiency.
💡 Did You Know?
Most brands push B6 past 100% daily value. First Day doses it to what a growing body needs, enough to support the serotonin and dopamine behind mood.
Growth and developmental milestones depend on a foundation most toddler vitamins skip entirely.
💡 Did You Know?
Bone and physical development at this age needs Vitamin D3 and K2 working together. First Day pairs them intentionally — because at this stage, half the equation isn't enough.
💡 Did You Know?
Here's something most parents don't know: The FDA uses the same nutritional research for a 2-year-old and a 45-year-old, and that is based on 50-year old science. Take vitamin B6, for example. The Daily Value is 1.7mg, even though a 2-year-old actually needs closer to 0.6mg. Over time, high intakes of vitamin B6 have been linked to neuropathy—a reminder that vitamins should be dosed specifically.
A toddler's body isn't a smaller version of an older kid's. It needs its own dose, calibrated to what a toddler-sized, still-forming system can actually handle — not scaled down from someone else's number.
💡 Did You Know?
Tantrums. Speech delays. Missed milestones. They point to real deficiencies — but most brands only treat the symptom, never where it comes from.
The food you're offering your toddler isn't delivering what it used to. Fresh produce has lost up to 73% of its nutrients over the past 50 years, and microplastics and heavy metals make it even harder for a developing brain to get what it needs.
That's why First Day formulates for both sides of the problem: what's missing inside your toddler's body, and what's working against them outside it. We call it Bio-Matched.
We match every nutrient to your child's exact age, using the right forms and doses through our exclusive Bio-Matched™ Formula.
First Day starts with what real toddlers actually need. Then we match every nutrient to the right form and precise dosage for their adolescent bodies. Nothing extra. Nothing missing.

Remember the old adage "more isn't always better"? Many vitamins today use cheap chemicals that our bodies can't absorb in amounts that are much higher than we actually need! In the long term, taking these sorts of vitamins can be harmful to health because our bodies have a tough time getting rid of the excess.
Take plants as an example. Overwatering your plants can damage their roots, wilt the leaves, and ruin their growth. That's why First Day focuses on being a nourishing vitamin filling in the gaps, not overloading you with nutrients.
So, we've consciously formulated our vitamin around what we most commonly lack. Then we made our gummy to fill the gaps in our everyday needs with the finest ingredients.
We set out by asking the unaddressed questions in the industry. What are supplements really doing for us? Why are they made the way they are?
We found the average multivitamin uses outdated science from 50 years ago.
To separate truth from fiction, our team of experts investigated thousands of clinical studies. That’s why we use the latest science and source the most absorbable ingredients from all around the world so your vitamins are actually working for you and your health.
Healthy habits are hard to start let alone maintain! We wanted to make it as simple as one-click to building healthy foundations. With your subscription, you get a discount on every order for being a loyal First Day family member! Plus, cancelling a subscription is easy.
For every order, we also have a satisfaction guarantee so you can rest assured knowing we'll always have your back!
Micronutrients, absorption rate, and more! We've combed through the scientific studies so that you don't have to. But if you want to peruse, check out these scientific studies for yourself:
My kiddos have never been more excited about vitamins. They actually ask to take their vitamins daily now. As a mom I love that I have found vitamins my kids love to take and I feel good about giving them.
The best vitamin we have tried. My kids are so picky and hate the chalky tablets. Very thankful I found this amazing gummy! Never a meltdown over taking their daily vitamins!

1 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!
