Ad ideas for First Day on Meta.

📉 At age 8, about half of kids are getting enough choline. By age 9, it's one in ten.

We had to read that twice.

Choline is what the brain uses to make acetylcholine, which works a little like a filter. It decides what gets noticed and what gets tuned out. So focus isn't really a personality thing. It's more of a supply thing.

And the supply drops off right around 4th grade, which is the same year school starts asking for a lot more of it.

🧠 That timing is the whole reason Kids Brain Focus exists. It uses Cognizin® citicoline, a form the brain already knows what to do with, at a dose meant for a 4 to 12 year old. Not an adult dose made smaller.

"We have been using these vitamins for our 2 teens for the last 2 months. They both play rec sports and therefore have very busy schedules. We highly recommend these vitamins to others who want to help balance the nutritional needs of their children. Thank you First Day!"

With over 5,000+ ⭐⭐⭐⭐⭐ reviews…

Mothers nationwide are discovering that First Day is exactly what’s needed to get their teens balanced -- nutritionally, & mentally.

It’s unique blend of:
🍓 Vitamins sourced from vegetables and fruits
🧠 9 key nutrients needed for growth and development
🍭 Low sugar formulation (with no sweetener additives!)
& No GMO, artificial colors or additives…

First Day vitamins do exactly what’s said on the packet --- enrich the body, and give teens the nutrients they need to thrive!

And since we first started...

So many mothers have stepped forward to share how this simple Nutritional Switch has created a complete turning point in their teen's lives.

Discover why 1,000s of parents are making the switch!

90% of your child's brain develops before age five.

Let that sink in for a second.

Which means right now — during the mac and cheese phase, the fruit pouch phase, the will-only-eat-beige-foods phase — their brain is building its foundation.

And most parents have no idea there's a gap.

Here's the thing nobody told me:
The folate in almost every kids vitamin on the shelf is folic acid. Sounds fine, right? Except nearly 40% of kids have a gene variant that makes it literally impossible for their bodies to convert it.

The gummy gets eaten. Nothing gets absorbed. You just never find out.

That's exactly why First Day is formulated differently.
🧬 Methylfolate — the form that bypasses the absorption problem entirely
🧠 Methylated B12 — what the developing brain actually runs on ☀️ Vegan D3 + K2 — so the right nutrients go to the right places
🫐 21 organic superfoods. Right amounts. Not megadoses.

Developed with input from Yale and Harvard pediatric researchers. Clean Label Project Certified. Third-party tested. Made in Germany.

Over 1 million families have already made the switch.

Discover what your child's brain actually needs right now.

"My daughter would only eat plain pasta and chicken nuggets. I was genuinely worried about what she was missing. First Day changed everything — she asks for her gummies every morning now!" SARAH M. ⭐⭐⭐⭐⭐

With over 5,000+ ⭐⭐⭐⭐⭐ reviews...
Parents of picky eaters nationwide are discovering that First Day fills the gaps that even the most stubborn little eaters leave behind.

Because here's the truth most parents don't know:
93% of kids aren't eating enough fruits and vegetables every day. And even the ones who are? Modern produce has significantly fewer nutrients than it did a generation ago.
That's exactly why First Day was built.

Each serving packs:
🫐 21 organic superfoods including kale, spinach, reishi, and moringa
🧬 Methylated B12 and folate, the forms kids' bodies actually absorb
☀️ Vitamin D3, K2, and zinc for immunity, growth, and development
🍬 Only 2g of sugar up to 80% less than leading brands
✅ Clean Label Project Certified. Zero heavy metals.
Two gummies a day. That's it.

And since we first started... more than one million families have made the switch.

Discover why parents of picky eaters are calling this the easiest win in their kid's health routine

Right now, your kid probably isn't growing at all. 📏

Researchers who measured children daily found something nobody tells parents: kids are measurably not growing over 90% of the time. Then, usually after a long stretch of sleep, they gain up to a centimeter overnight. 😴

Growth isn't a slow steady climb you can feed on average. It's a spike. And there's no catching up on a spike after it's passed.

Which is what the nutrients have to be ready for:
🔑 Methylfolate for the cell building a growth burst runs on
🩸 B12 for red blood cells carrying oxygen to tissue that's building
☀️ Vitamin D3 to direct calcium toward bone and healthy height development
🎯 K2 to make sure that calcium lands in bone and not soft tissue

First Day Kids Multi is Bio-Matched: the forms a child's body actually recognizes, at doses calibrated for 4 to 12 rather than an adult formula scaled down. 🧬

Not the highest dose. The right one, ready on the night their body decides to use it.

See the full breakdown 👇
I can relate - that was my life...Every...Single...Day. Until I found this 👇

After some research, I found out that SO many of the common "parenting frustrations" are tied to one issue:

Nutritional deficiencies!

Did you know that over 70% of American kids are deficient in Vitamin D? I didn't either....

But those “ferocious fours” and “growing pains” are actually signs of bigger issues - and you don’t need to live with them. I don't anymore!!!
