What every parent with an MTHFR kid needs to know.
I used to think giving my daughter a multivitamin was the responsible thing to do.
Until I learned the hard way:
Not all vitamins are safe for every child.
Especially if your child — like mine — has an MTHFR mutation.
Here’s what no one tells you about folic acid:
Most kids’ vitamins use synthetic folic acid — the cheap, man-made version of vitamin B9.
But if your child has MTHFR (and up to 40% of kids do), their body can’t convert it into a usable form.
Instead, it builds up in their system and can cause:
- Irritability
- Fatigue
- Sleep issues
- Neurological symptoms
- Even developmental delays in some cases
I was giving her vitamins to help — and they were quietly making her worse.
The fix? Give them the version their body can actually use: L-methylfolate.
That’s when I found First Day.
It’s one of the only kids’ multivitamins that doesn’t use folic acid at all.
Instead, it uses L-methylfolate — the bioactive form that’s safe and absorbable for MTHFR kids.
No guessing. No conversion issues. No risk.
And it doesn’t stop there:
- ✅ Backed by Harvard and Yale scientists
- ✅ Includes other essentials like B1, D3, and K2 for focus, mood, immunity
- ✅ Made with a blend of 21 organic superfoods
- ✅ Zero sugar alcohols, artificial dyes, or synthetic junk
- ✅ Kids actually take it (mine thinks it’s candy)
What happened when we switched:
Within 2 weeks, I saw changes I hadn’t seen in months:
- Calmer afternoons
- Less moodiness
- Easier mornings
- And most of all — she felt better in her body
It wasn’t magic. It was nutrients her system could finally absorb.
If your child has MTHFR — or you even suspect they do — don’t risk folic acid.
Most mainstream gummies still use it.
First Day doesn’t. And the difference is night and day.
