What's are the ingredients?
Why do you have less than 100% of daily values?
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.
What else is different about First Day?
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We found the average multivitamin uses outdated science from 50 years ago.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.
Should I subscribe if I've never tried First Day before?
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!
Which scientific studies does First Day look at?
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:

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!
