I hesitate to label my son solely by his diagnosis. Autism is a part of Nathan, but it does not define him. He chooses how autism shapes his life. Still, for clarity: Nathan is an autistic child.
Nathan is 12 and was diagnosed with high-functioning autism last year. He’s a generally happy, outgoing seventh grader who does well in school—still a straight-A student. Life with a child on the spectrum has its ups and downs, but recently Nathan has made major progress. Importantly, these improvements have occurred without medication in our case (and that’s a personal choice—every family must do what’s best for their child).
We implemented several practical changes and Nathan responded remarkably well. What follows are three key, evidence-informed adjustments that helped our son thrive. As always, consult your child’s doctor before making major changes.
Three Essential Changes That Improved Our Son’s Functioning
(Disclaimer: every child is different. Talk with your medical provider before changing treatments, supplements, or diet.)
1. Genetic testing and targeted vitamins (MTHFR)
Our family doctor tested Nathan for an MTHFR genetic variation. This mutation is common in the general population and appears frequently in children with autism. Nathan tested positive for two copies of an MTHFR variant, which can affect how the body processes certain nutrients and toxins, including synthetic folic acid.
Under medical guidance, Nathan began taking methylfolate and a specific form of vitamin B12. These are targeted supplements that can support biochemical pathways affected by MTHFR variations. Within a few months we noticed meaningful changes: he became calmer, less reactive, and more in control of his emotions and behavior. The supplements were affordable and easy to include in his daily routine. If you suspect a similar issue for your child, discuss testing and options with your physician.
2. Diet adjustments
Diet changes have been an important part of Nathan’s progress. Over several years we removed food dyes, especially yellow #5, red #40, and blue #1. When those dyes were eliminated, his behavior stabilized. When he ate foods containing dyes, his behavior often declined.
We also removed high-fructose corn syrup, which produced noticeable benefits. More recently our family adopted a gluten-free diet, and Nathan continued to improve. Our next step is to trial a dairy-free, more paleo-style approach. While restrictive diets can be challenging to maintain, for many families small, gradual changes produce large benefits. Always introduce dietary changes in consultation with a healthcare professional or registered dietitian to ensure nutrition remains balanced.
3. Predictable routine
Routine has long been known to help many autistic children. For us, establishing clear, consistent expectations made daily life calmer. I learned to stop aiming for a perfect schedule and instead created a flexible routine Nathan could rely on. When he knows what to expect and what’s expected of him, he’s less anxious and better able to participate in family life.
Simple, firm rules helped. Previously Nathan would rush home, hurriedly finish homework and chores, and then immediately ask to play Minecraft. This year we set a clear rule: no Minecraft, TV, or computer time right after school. He earns a limited period of Minecraft after completing homework and chores and after dinner. Having that structure reduced stress for everyone and improved his behavior and mood.

These changes have brought our son closer to functioning like his peers most of the time. He still has occasional frustrations, but severe tantrums have become rare. The progress feels profound: we have more of the child we know and love in our family life. The dietary and lifestyle adjustments require effort, but the improvements in Nathan’s well-being make them worthwhile.
If your child is on the autism spectrum, consider discussing genetic testing, targeted supplementation, gradual dietary adjustments, and consistent routines with trusted professionals. What helps one child may not work for another, but these strategies are practical starting points that improved life for our family.
