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

How This Helps*

A kid who zones out, loses focus mid-sentence, or shuts down when tasks get hard isn't necessarily struggling with attention, they may just be running low on the B vitamins their brain needs to signal, process, and retain information.

🧠 Vitamin B1 — supports brain signaling and working memory

🪄 Vitamin B2 — maintains the nerve function kids need to stay sharp through a full school day

🧬 Vitamin B6 — supports the neurotransmitter pathways that drive attention and cognitive clarity

How This Helps*

A picky eater isn't just frustrating at dinner. They're quietly building nutrient gaps that compound through the years their brains and bodies are developing fastest.

🧠 21 organic superfoods blend — apple, kale, broccoli, spinach, blueberry, and 16 more; the nutrients from foods most picky eaters won't touch

🍑 Vitamin A (as beta-carotene) — supports healthy vision and cell development; harder to get without vegetables

🍊 Vitamin C — supports immunity and iron absorption; commonly low in kids with limited diets

How This Helps*

Up to 40% of kids have the MTHFR gene that prevents them from converting folic acid, the cheap form of folate that almost every other vitamin uses. This means they’re not absorbing a critical nutrient they need for development.

🧬 Methylfolate (as L-methylfolate) — the active form of folate; absorbed and used immediately without conversion, even in kids with MTHFR

🧠 Vitamin B12 (as methylcobalamin) — another carefully selected form; supports healthy nerve function and red blood cell development

🫐 21 organic superfoods — delivers folate and B vitamins in whole-food form, the way the body expects to receive them

🚨 Due to the high demand, July has a very high risk of selling out!

Kids daily multivitamin made with easily absorbable nutrients

What stands out to me about First Day's Kids' Multivitamin gummies is the attention to ingredient form. For example, B12 is included as methylcobalamin, the naturally occurring form of this vitamin found in food. Then folate is provided as methylfolate, the active form that can be used without conversion, which may be particularly relevant for children with common variants of the MTHFR gene that can affect how standard folic acid is processed. Lastly, Vitamin D3 is sourced from lichen, making it a fully plant-based form of cholecalciferol, the same form the body produces from sunlight. Research consistently indicates that D3 may be better than D2 for maintaining healthy vitamin D levels in children. For parents seeking a daily children's multivitamin, these ingredient choices are why I recommend this particular formula.†

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.
