My son is VERY picky but gets so excited to eat these. I unfortunately tried hiya first & wasted money because he would not eat them. I love that these are a gummy soft chewable.

Delivering The Nutrients a Growing Kid Needs

How This Helps*

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.

🧠 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

From our Founder

Did you know 1 in 3 Families have a nutrient deficiency? I created First Day to address the massive concerns with todays diet and it's negative effects on our families.

  • The Average Person Consumes 52 Credit Cards’ Worth Of Microplastics Every Year.
  • Artificial Food Additives Are Found In 59% Of Foods Today
  • Fresh Fruits & Veggies Have Lost Up To 73% Of Their Nutrients

After learning about the massive amounts of sugar that were in typical kids multivitamins I reached out to 2 of the top researchers at Harvard and Yale. I explained my story to them, how I wanted to revolutionize the vitamin industry. After consulting with these experts to help us carefully formulate our vitamins, we are now a best selling multivitamin nationwide.

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.
