Learn about the Hidden Hunger crisis and Vanishing Nutrients:
Hidden Hunger: the health crisis affecting MILLIONS of teens, even in the US...
Many people are suffering from something completely invisible from the human eye. UNICEF (The United Nations Children's Fund) has called this discovery "Hidden Hunger" – used to describe nutrient deficiencies.
This hidden problem is tied to (not so hidden) symptoms. Deficiencies are often linked to challenges around behavior, immunity, mental health, and sleep.
Our solution makes it easy— no more begging your teen to eat their vegetables. Just two delicious daily gummies, jam packed with essential nutrients, help address common symptoms of nutrient gaps that can impact your teen's well-being.
Vanishing Nutrients: the reason why even teens with balanced diets might not get the nutrients they need...
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. In fact, a recent study from Scientific American revealed that one would need to eat EIGHT oranges today to get the same amount of nutrition that our grandparents would have gotten from ONE.
To make up for nutrient gaps, we need to consider more than just "good food". We need to feel confident our teens are always getting a consistent support of good health.

I saw an ad about these vitamins online and they were describing my teen perfectly, so I told my husband we should give them a try to see if they worked. We could both tell a change in first two weeks and even better is our daughter could tell a difference. She felt better about herself, her attitude improved and as a result her focus and school work also improved.

I knew my teen did not get the proper nutrition because vegetables were not something she loved. So when I saw that First Day had all the fruits and vegetables she needed, and it was supposed to help with the moodiness, I felt I had to try. Within the first week, I noticed a difference in her mood. She seems more balanced now, happier in the mornings, less tired. We will continue to use these vitamins from now on. It gives me peace knowing she is getting the nutrients she needs.

"I truly believe in our mission of bringing better health to families."
After learning about the massive amounts of sugar that were in typical kids 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 kids nutrition.
