Learn About the Hidden Hunger Crisis and Vanishing Nutrients
Hidden Hunger: the health crisis affecting MILLIONS of teens, even in the US...
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 mealtime battles or endless coaxing to eat vegetables. Just two delicious daily gummies, jam packed with essential nutrients, help address common symptoms of nutrient gaps that can impact your child'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 kids are always getting a consistent support of good health.

"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.
That's why we’re so confident First Day will help you get the results you want. If within the first 45 days you find yourself not completely satisfied, we’ll give you your money back - no questions asked.**"
