Our Multi Helps Where Your Teen Is Struggling (Even When You're Doing Everything Right)
The United Nations Children's Fund has identified a growing crisis affecting teens worldwide called Hidden Hunger. It has nothing to do with how much your teen eats, and everything to do with what's missing from the food they love.
If your teen struggles to fall asleep, stay focused, or keep their emotions in check, nutritional deficiency may be the invisible culprit. Targeted nutrients work at the root level — so your teen can finally feel like themselves again.
Chicken nuggets, pizza, fries — we get it, the kitchen table is a battle parents often lose. But a diet that works for peace at dinner doesn't always give teens what they need to grow. That gap is exactly what this formula is designed to fill.
When nutritional deficiencies go unaddressed, the effects can compound over time. And some consequences can't be undone. This is the kind of problem that's far easier to prevent than to fix.
Most supplements are made for adults or young children, leaving teens in a nutritional no-man's-land. This formula accounts for the unique demands of a developing teenage body and brain.
The best supplement is the one they'll actually take. No convincing, no hiding it in food. It's a flavor they look forward to every day.
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.†
