The Science Behind Our Kid's Multivitamin
When kids melt down, snap, or can't hold it together it's easy to blame the phase. But the brain needs specific nutrients to regulate emotions. When those run low, kids literally can't manage their reactions.
How This Helps*
🧠
Methylfolate (not folic acid) — the bioavailable form that supports neurotransmitter production regardless of genetic variation
⚡
Vitamin B6 — plays a direct role in how the brain produces serotonin and dopamine
🫐
21 organic superfoods — delivers whole-food nutrients that support healthy brain development
Benefits You Don't Want To Miss Out On
We’ve crafted a formula specifically for teens, using the latest nutritional science to support their unique needs—like focus, energy, sleep, mood, and overall wellness.
Our ingredients are carefully selected and based on research to help close common nutrient gaps during this critical stage of growth and development.
Parents and doctors agree—our vitamins make a real difference in teens' health.
Behavior
Methylfolate and Vitamin B6 support the neurotransmitter production that helps kids regulate emotions and reactions.*
Focus & Attention
Vitamins B1, B2, and B6 support brain signaling, nerve function, and the cognitive pathways kids need to stay on task.*
MTHFR & Folate Support:
First Day uses methylfolate, not folic acid — the bioavailable form that works for all kids, including the 40% whose bodies can't convert folic acid.*
Up To 40% Of Kids Have The MTHFR Mutation, Is Your Child Included?
Kids with the MTHFR gene aren't able to convert folic acid into its active form, which can lead to certain health risks. Thankfully, our vitamin includes methylated folate so your children can fight irritability, tiredness, and low motivation.
