Picture Your Teen Finally Waking Up Energized After a Full Night's Sleep
All thanks to 2 delicious gummies.
In a single bite, your teen gets crucial vitamins to support a good night’s sleep.* And they get to work before you know it!
  • Melatonin Regulation Vitamin D is crucial to the regulation of melatonin, aka the sleep hormone that determines that sleep–wake cycle.
  • Relaxation Vitamin C is to thank for managing cortisol, aka the stress hormone, that also plays a part in well–rested nights for teens.
  • Balanced Moods Vitamin B6 helps with serotonin production and also helps to manage melatonin levels.*
When Teens Aren't Well–Rested,
the Whole Family Feels It
Our superfood gummy, designed by experts and parents, delivers essential nutrients to help your teen get a better night's sleep. Because when your teen sleeps better, family life runs more smoothly.*
VITAMIN D
Vitamin D3 plays a key part in regulating production of melatonin, the hormone that controls sleep–wake cycles. It also supports overall brain health, which can improve sleep quality.*
VITAMIN C
Vitamin C promotes relaxation, making it easier to fall asleep. It also supports the body in managing cortisol, the stress hormone, which is known to affect sleep.*
VITAMIN B6
Vitamin B6 helps your body make serotonin, which is important for keeping your mood balanced. It also helps manage melatonin levels, which are vital for a good night's sleep.*

Hidden Hunger:

Unmasking a hidden health crisis depriving teens of their potential.
The shocking truth behind why over 50% of kids may be missing out on critical vitamins
Many people are suffering from something completely invisible from the human eye.
UNICEF (The United Nations Children's Fund) calls this issue "Hidden Hunger," which refers to nutrient deficiencies that are invisible to the eye. While the signs of poor nutrition may not be obvious, they can manifest in very real and noticeable ways, especially when it comes to sleep.
Many teens experience moodiness, grumpiness, or difficulty concentrating, which are often mistaken for typical behavior. However, these challenges can be tied to poor sleep quality—something many parents might not realize is rooted in their teen's nutrition.
It’s easy to think, "If my teens are eating well, they won’t have these problems." But that assumption can be misleading.
What many parents don’t understand is that countless teens around the world are still lacking essential vitamins, even if they seem to have a balanced diet.
The truth is, there’s a larger issue lurking beneath the surface.
Vanishing Nutrients
It's not just about what we eat anymore, but what's happening to our food.
Studies are revealing shocking declines in nutrient levels across crops. Scientists are calling this worldwide crisis Vanishing Nutrients.
From soil depletion to global warming, our food is losing its nutritional punch. This nutrient loss can lead to various health concerns, including poor sleep.
Parents might see their teens being moody or grumpy and not realize that the real problem could be poor sleep caused by not getting enough good nutrients.
That's why every minute counts when it comes to your teen's health. To make up for nutrient gaps, we need to consider more than just "good food." We need to ensure our teens always get consistent support for good health, and that includes restful sleep.

My daughter loves the flavors. We are on the second week now. She's been sleeping through the night and her appetite has gotten better. Hoping this vitamin can help with her focus too. Will recommend.

I tried these vitamins a couple months back, along with some other changes, and finally saw an improvement. When we gradually finished the bottle and moved on in life, we slipped back to chaos. It had been a rough couple months of me trying a million things again, when my husband pointed out: "what were we doing a couple months ago when we had improvement?" And I remembered these vitamins from First Day! I promptly went and ordered them again, and we're on week 2 and he's already sleeping better which we all know makes everything already better!

We started giving First Year vitamins to my son just a couple weeks ago just praying it would help with his sleep (with the bonus of a great vitamin full of goodness for him.)
When I say bedtime has gotten so much better with him in this short time I am not joking even a little about it. I'm pretty impressed to say the least! He also loves the taste!

"I truly believe in our mission of bringing better health to families. If you're not happy, we'll give your money back. No questions asked."
After learning about the massive amounts of sugar that were in typical teens' multivitamins, I built a list of 198 Harvard and Yale nutritionists, pediatricians, and professors. From there, two of the top researchers at Harvard and Yale agreed to help!
I explained my story to them, how I wanted to help parents, and what I found about the vitamin industry. And they were a huge help in creating this breakthrough in teens nutrition.
At the start, I just wanted to find the truth about the vitamin industry. But together, they helped to create something that parents love!
That's why we’re so confident First Day will help you get the results you want that we want it to be absolutely risk-free for you. If within the first 45 days you find yourself not completely satisfied, we’ll give you your money back - no questions asked.**
