Learn About the Hidden Hunger Crisis
and Vanishing Nutrients
Hidden Hunger: the health crisis affecting MILLIONS of kids, 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 kids 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 was looking for a multivitamin for my 5 year old because he is a picky eater and I wanted to make sure he was getting all the vitamins that he needs that he doesn’t get from the limited food items he eats. I tried other vitamins and he didn’t like the tablet consistency, but he loves First Day and I've seen the difference it’s made! His mood is better and he’s actually been trying other foods. I also just added the probiotics in his daily and it’s really working for us!"
"This is a perfect vitamin for a picky eating child. My daughter has been taking her vitamins on a daily routine. It has helped her keep focus for school and her weekly dance class. With her picky eating habits, I was very concerned she was missing essential nutrients, so I researched best vitamins and found First Day."
We absolutely love First Day Enrichment Kids Vitamins! My kids look forward to taking them every morning, they love the taste, which makes it so easy for me. These vitamins have made such a positive difference, giving them a noticeable boost in energy and focus. I feel great knowing they’re getting high-quality, natural ingredients to support their health and growth. Highly recommend for any parent wanting a vitamin their kids will actually enjoy!
I've been giving my kids First Day Kids Multivitamins, and we love them! They really love the fruity flavor and the chewy texture. No more struggles to get them to take their vitamins—they remind me and even want MORE! It’s comforting to know my kids are getting clean, healthy nutrients. Since starting these, my kids have more energy and seem happier and more focused. I can really see the difference! and noticed that they have not gotten sick (Knock on wood) Highly recommend!"

"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.
