Target 5 Symptoms of Nutrient Deficiencies with Just 2 Daily Gummies
Unbalanced Mood & Behavior
May be missing essential B vitamins, which help support emotional regulation and neurotransmitter function.
When these nutrients are lacking, kids may experience increased irritability, mood swings, or difficulty managing emotions.
Poor Sleep Habits
May be missing Vitamin B6 & D3, which play key roles in supporting restful sleep.
These nutrients help regulate melatonin production and promote relaxation, making it easier for kids to wind down and stay asleep through the night.
Difficulty Concentrating
May be missing critical B vitamins, which support brain function and cognitive clarity. These nutrients help convert food into energy, keeping kids alert, focused, and ready to learn.
Our formula is designed with precision, ensuring kids get exactly what they need, in forms their bodies can actually use—without unnecessary megadoses or poor ingredient pairings.
Picky Eating Habits
May be missing Vitamin B12 & B6, which are essential for appetite regulation and nutrient absorption.
When these vitamins are low, kids may develop stronger food aversions and struggle to get the variety of nutrients they need from their diet.
Weakened Immunity & Frequent Colds
May be missing Vitamin C & D3, which are crucial for maintaining a strong immune system.
These nutrients help the body fight off common colds, support overall resilience, and promote a faster recovery when illness strikes.

"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.**"
