Will this help my child, or is it one more thing that won’t? That question sits behind every bottle, app and program sold to a worried parent. The ads sound sure, and you are the one left guessing. Wanting to try everything is not foolish. It is what caring looks like. And you don’t need a science degree to sort these out. You only need the right tools.
Common questions from parents
How do I know if a focus supplement is worth trying?
Does fish oil help a child who struggles with reading?
Do brain training apps help with schoolwork?
Does vision therapy help dyslexia?
Should I find out what my child struggles with before I buy a program?
The focus supplement, the brain app, the vision program. Each pitch sounds sure. Four questions show which claims hold up before you pay.
Why does every pitch sound so sure?
A pitch for a struggling child is built around your hope. It names the thing you fear. Then it sells the thing that seems to end the fear. Our view is plain. A parent with a struggling child is a target. The honest version is more useful than the sales version.
So set aside the big question: is this product good? Nobody answers that from a box. Ask a smaller question. Does the claim hold up to four questions?
- What was measured? Was it the skill you care about, like reading or focus? Or something else?
- In how many children, and of what age? A handful of children is not a big trial.
- Compared with what? A dummy pill, another program, or nothing at all?
- Was the change big enough to notice? Would you see it on a real school day?
A claim worth your money answers all four. These questions come from how we read any claim about food and learning. We use them on apps and eye programs too. We ran one amino acid pitch through them, step by step.
A happy customer is a story, not a measure.

What happens when you ask about a supplement?
Take fish oil. It is sold to parents as help for learning and focus. Start with question one. What was measured?
A Cochrane review (Tan, Ho and Teh, 2016) looked at fatty-acid supplements for children with learning difficulties. It found two small trials. Neither one reported reading, writing, spelling or math scores. In the review’s own words: “Evidence is insufficient to permit any conclusions.”
That does not mean fish oil fails. It means those trials did not measure what you care about. So the claim stops at question one. Here is what that review found, and who to ask.
Focus claims get the same test. How was focus measured, in whom, and against what? A happy customer is a story, not a measure. Then take the bottle to your child’s doctor. Diet and supplements are medical questions. A real shortage of a nutrient is something a doctor checks for. We also wrote about what nutrients do for a struggling learner, and about what the supplement aisle oversells.
Key takeaways
- Ask four questions: What was measured, in whom, against what, and how big?
- Check what was measured: A supplement review found no reading scores to judge.
- Vision is not the cause: Eye-care groups said vision problems do not cause dyslexia.
What about brain apps and vision programs?
The brain app. It might promise sharper focus or better grades. Ask question one. Did your child get better at the game, or at schoolwork? Getting better at the game shows one thing. Your child got better at the game. Ask for reading, math or class focus results. Then ask question three. Were the app kids compared with kids who did nothing? Or with kids who spent that time reading? Here is what brain training programs claim, and what independent reviews found.
Watch for one phrase: “matches how your child learns.” Teaching to a child’s learning style was checked in 2008 and again in 2024 (Pashler et al., 2008; Clinton-Lisell and Litzinger, 2024). Both times, the evidence did not justify matching. You have your answer on that one.
The vision program. Some programs sell eye exercises for reading trouble. Here the answer is already in. In 2009, four children’s health and eye-care groups said vision problems do not cause dyslexia. They reaffirmed it in 2014. The pediatrics group retired it in 2025. AAPOS, a group of children’s eye doctors, says it plainly: “Don’t recommend vision therapy for patients with dyslexia.” Read more on vision therapy and dyslexia.
Colored overlays meet question three. A 2016 review (Griffiths and colleagues) found the evidence does not support them for reading. The authors said reported gains were likely due to “placebo, practice or Hawthorne effects.” That last one means doing better because someone is watching.
We are not against eye care. A separate near-vision problem makes reading uncomfortable. An ordinary screening does not always catch it. An eye exam that checks near vision is worth having. If you suspect a vision, hearing or medical cause, see a professional.
Tonight: save the four questions in your phone. Next time a pitch lands, send them to the seller. A claim worth trusting will answer them.
A claim worth your money answers all four questions.

We believe your child’s time, money and hope belong on what works. The sales version of help is built for your worry, not your child’s need. Nobody will ever advocate for your child as hard as you will.
Before you buy anything, get clear on what you see. A screener is a starting point, not a diagnosis. Only a professional evaluation leads to an IEP or 504 plan. Our free screener asks what you see in reading, math, writing and focus: start the Learning Difficulties Analysis.

Is your child struggling in school?
Get your free personalized learning roadmap
You describe what you see at home. We turn it into a plan you start this week.
- Answer 5 short questionnaires about what you already notice, 30–45 minutes at your own kitchen table
- Your child sits no test and gets no score: nothing to schedule, nothing for them to dread
- You do the answering, the AI does the writing, and a person reviews it before it reaches you
- Access all 40+ courses instantly: reading, math, focus, processing and more, with new ones added regularly
Why we use AI, plainly: it writes from a knowledge base our team maintains and audits. We work through it line by line and pull anything the evidence stops supporting. The roadmap you get on Tuesday reflects what we corrected on Monday, and a human still reads it before you do.
Your school district must evaluate your child free of charge if you ask in writing, whatever your income and whatever the outcome (US, 34 CFR 300.111 and 300.301(b)). That route takes time and answers a different question than you do. This one starts today, from what you already know.
Your answers stay yours. We do not sell your personal information, and we do not hand identifiable assessment data to outside AI companies to train their models.
A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing or medical cause, pursue a professional evaluation too. That is the only route to those supports.
