3 Building Blocks for Healthy Brain Development & Mood Support
VITAMIN B6
Vitamin B6 is important for helping your teen stay calm and happy! It supports their brain in making the chemicals that keep moods balanced. With enough Vitamin B6, teens can handle stress better and feel more relaxed.*
FOLATE
Folate is like a brain booster! It helps your teen's brain grow and develop, making it easier for them to learn new things and remember what they've learned.* Folate also supports the production of healthy red blood cells, which keeps their brain sharp and focused.
VITAMIN B12
Vitamin B12 plays a big role in keeping your teen's mood balanced and calm! It helps their body turn food into energy, so they feel more focused. Teens getting enough B12 can manage stress better and stay relaxed, even when life gets busy or overwhelming.*

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 brain health.
Many teens experience moodiness, grumpiness, or difficulty concentrating, which are often mistaken for typical behavior. However, these challenges can be tied to feelings of anxiousness or constantly feeling overwhelmed—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 increased stress responses, such as feeling anxious, overwhelmed, and generally more stressed out in social situations.
Parents might see their teens struggling in school or having trouble making friends and not realize that it could be 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.

"Noticed a huge difference."
"This has been the best vitamin for my teens! My teens have gone from constant attitude to having an actual conversation with me! We definitely still have our days but they’re much calmer and have a better attitude.
My daughter also went from complaining of a stomach ache every day and being asked to be picked up from school to now not hearing from her during the school day and when I pick her up, saying she had a good day! I am so grateful for the change."

"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 teen 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. Within 45 days, if you don't find yourself completely satisfied, we’ll give you your money back - no questions asked.**
Give Your Teens a Fighting Chance
First Day has become the #1 multivitamin for so many parents. And it could be the perfect fit for you.
But here's the thing:
We source the best possible ingredients on purpose. But due to global shortage, if we run out of methylfolate, we won’t be able to ship our products because we don’t want to put just any ingredient into our product.
We’ve already sold out 6 times so make sure to use this opportunity now. Order today to guarantee your bottles from our warehouse.
