What the studies found in kids and teens.
Three placebo-controlled trials, two added to usual care.
Less irritability, ages 4–12
Autistic kids: less irritability and hyperactivity than placebo in 10 weeks, added to their usual medication.
Calmer and more social
Ages 13–27 with autism: better behavior and social scores than placebo, over 18 weeks.
Studied in children
Given to children in supervised trials, with side effects similar to placebo.
Another call from school? It isn't your fault, or theirs.
The meltdown before school. The homework that ends in tears.
You've tried the charts, the therapy, cutting the sugar.
All of that helps. Some days still fall apart anyway.
Every brain has its own defense system, called Nrf2.
Every morning, Rejoin helps switch it on.
The compound behind the kids' trials, from broccoli sprouts
Sprouts carry up to 100× more glucoraphanin than broccoli.
Their enzyme turns it into sulforaphane.
- What's built into every capsule:
-
Glucoraphanin, the raw ingredient from broccoli sprouts
-
Myrosinase, the enzyme that converts it
-
An acid-resistant capsule to hold up to stomach acid
-
Switches on the brain's own defense, Nrf2
-
Switches on the body's own clean-up enzymes
-
16 mg sulforaphane in every capsule
Therapy and routines help. They can't reach inside cells.
OT, a good diet and a multivitamin all matter.
None of them switch on the brain's own defense.
Instead of OT alone:
- OT builds real skills, and that matters.
- It works from the outside, a session at a time.
Rejoin Daily Defense delivers:
- Works inside the cells, every single morning
- Less irritability in a placebo-controlled kids' trial
Instead of a multivitamin alone:
- It fills gaps in the diet.
- It isn't built to switch on Nrf2.
Rejoin Daily Defense delivers:
- Switches on the body's own defense, Nrf2
- Less inattention in a 2025 kids' ADHD trial
Instead of diet changes alone:
- Cutting sugar helps some kids.
- Try getting a picky eater to chew bitter sprouts.
Rejoin Daily Defense delivers:
- The sulforaphane from sprouts, no chewing required
- 16 mg in every capsule, no guessing

What our customers are saying
Angela R.
“About 3 weeks in, his teacher stopped me at pickup”
My 8-year-old is autistic. School called almost every week. About 3 weeks in, his teacher stopped me at pickup. “Whatever changed at home, it's working. He's a different kid this month.” The calls home have basically stopped. We still have hard days. We mix the capsule into his morning yogurt. He has no idea.
Melissa V.
“He knocked over a glass of milk and just cleaned it up”
My son is 12 and has Asperger's. A sock feeling wrong could ruin four hours. We'd tried a multivitamin and occupational therapy. Around week 3, he knocked over a whole glass of milk. He just got a cloth. No screaming, no 2-hour spiral. He's still himself. But he recovers now. I started taking it myself, and I'm calmer too.
Harold F.
“His aide asked my daughter if anything was different at home”
I bought this for my 9-year-old grandson. His mum was at the end of her rope with school. About a month in, his aide asked if anything was different at home. He was sitting through lessons, finishing things. My daughter cried telling me. Supplement or timing, I don't know. I'll keep paying either way.
Nicole A.
“We both notice when we miss a few days”
My daughter and I both take this every morning. She's autistic, and I've always been high-anxiety. For her: fewer meltdowns. She coped with a dentist appointment last month that would have been a full-scale event before. For me: I'm just less wound up. We both notice when we miss a few days.
Jenna C.
“Won't eat a single green thing. The calmer mood was a bonus.”
My son won't eat a single green thing. Not one. I bought this mostly to fill the vegetable gap. The calmer mood was a surprise bonus. Docking a star because getting him to take the capsule took two weeks of negotiation. We crush it into apple sauce now.
Yvonne M.
“The difference in her was worth every bit of the fight”
Getting my daughter to take it was a real battle. She hated the taste when we opened the capsule into juice. Took us a while to crack it. But once we did, the difference in her was worth every bit of the fight.

Your questions, answered honestly
Is this instead of my child's ADHD medication?
+
No. In the 2025 trial, kids 6–11 all kept their usual ADHD medication.
Sulforaphane was added on top.
Parents and teachers saw more improvement than with placebo.
Never stop or change a child's medication on your own.
Talk to your pediatrician first.
Can I give it to my child?
+
Sulforaphane has been given to children aged 3 to 12
in supervised trials, with side effects similar to placebo.
Giving it to a child? Talk to your pediatrician first.
For kids it's one capsule a day (16 mg).
If your child takes medication, check with their doctor before use.
My child won't swallow capsules. Can I open it?
+
Swallowing it whole is best when they can.
The acid-resistant capsule protects it from stomach acid.
If they can't, some parents open it into cool yogurt or apple sauce.
Cool, never hot.
Stir it into a small spoonful they'll finish.
Does it help autistic kids too?
+
Two placebo-controlled trials say it's worth a look.
Kids 4–12, added to their usual medication: less irritability and hyperactivity.
Ages 13–27: better behavior and social scores over 18 weeks.
Not every trial agreed, so we call it early science.
Talk to your pediatrician, and judge it over 90 days.
Where's the proof? Isn't this just hype?
+
Fair question. The 2025 trial tested it against placebo.
70 kids aged 6–11 with ADHD, all on their usual medication.
After 8 weeks, parents and teachers both rated
less inattention and hyperactivity.
Side effects were similar to placebo.
Early science, real trials. You get 90 days to judge.
Why haven't I seen a change yet?
+
It isn't a stimulant, so there's no buzz and no crash.
Some parents hear it from school first, around week 3.
The ADHD trial measured at 8 weeks.
Parents at four to five months tell us their child bounces back faster.
That's why you get 90 days, not 30.
Why not just eat more broccoli or grow my own sprouts?
+
You can, and broccoli is good food.
Sprouts carry up to 100× more of the raw ingredient.
But growing them is a daily chore, and most kids won't eat them.
And you never know how much you got.
Two capsules give adults 32 mg a day, enzyme built in.
Can I take it too, if I'm pregnant or on medication?
+
Sulforaphane comes from broccoli sprouts, a food.
Texas A&M researchers found that when nursing mums eat broccoli sprouts, sulforaphane passes into their milk, and supervised trials have given it to pregnant women.
If you are pregnant, breastfeeding, trying to conceive or taking medication, check with your healthcare provider before use.
