The science behind nutrition, brainwaves, and what a bespoke plan might actually do for your ADHD.
I came across an EEG image this week β shared by Leanne Maskell on LinkedIn β that stopped me in my tracks. π
It showed brain activity frequencies tracked in real time. Chaotic spikes. Wild amplitude swings. A signal that looks like it can’t quite decide where to go.
And my first thought? That’s exactly what it feels like on the inside.
If you have ADHD, you know the feeling I’m talking about. Not just “a bit distracted.” That full-body, can’t-settle, brain-running-on-200-tabs experience.
But here’s the question that’s been living rent-free in my head ever since I saw that image:

What if we could watch that graph change? π
What if you took someone with ADHD, built them a truly bespoke nutrition plan β one that addressed their specific deficiencies, stabilised their blood sugar, supported their gut-brain axis β and then reimaged their brain at 4 weeks, 8 weeks, 12 weeks?
I believe you’d see something shift.
Not a neurotypical brain. Not a “fixed” brain. But a less chaotic one. Peaks a little less jagged. Signal a little more consistent.
And for those of us living inside those spikes? Even a little less chaos is a big deal. π
Here’s the science bit π¬
When I look at that EEG image, I see four key nutrients written all over it:
Iron
Low iron = less dopamine available = poorer signal regulation. That dysregulation? You can see it right there on the graph.
Zinc
Zinc regulates how your brain responds to the dopamine it does have. Too little zinc and the response becomes unpredictable. Those wild amplitude swings? Zinc is directly involved in smoothing them out.
Magnesium
Helps quiet down an over-excited nervous system. Low magnesium is one of the most consistent findings in ADHD research β and its effect on chaotic brainwave activity is genuinely significant.
DHA (Omega-3)
More DHA = signals travel more efficiently between neurons. Less DHA = the communication system becomes sluggish and erratic. Both show up in brainwave patterns.
A quick note, because I want to be honest with you: nutrition can’t “fix” ADHD. It can’t rewire the fundamental architecture of a neurodivergent brain β and it was never going to. That is not what this is about. π
What nutrition can do is give your brain the raw materials it needs to function at its best. To reduce the unnecessary chaos. To support the systems that are already there.

Imagine a 12-week nutrition journey… ποΈ
Here’s what I’d love to explore. What if we tracked this properly?
Week 1β2
Baseline assessment. Identify specific deficiencies, blood sugar patterns, gut health, neuroinflammation markers. No guessing β your plan.
Week 4
First reimage. Have iron, zinc, and magnesium levels begun to shift? Is the gut-brain axis starting to settle? Are you sleeping even slightly better?
Week 8
Mid-point check-in. DHA levels take time to build. But by now? Your nervous system has had weeks of genuine nutritional support. What does the graph look like?
Week 12
Final reimage. I genuinely believe you’d see something different. Not a neurotypical brain β but yours, with less unnecessary chaos getting in the way.
π Less chaos. Same brilliant brain.
That’s the goal. Not to change who you are. To help you access more of what’s already there β without fighting through so much static to get to it.
What this means for you π¬
If you’ve been wondering whether nutrition could genuinely make a difference for your ADHD β not in a vague “eat more vegetables” way, but in a targeted, personalised, evidence-informed way β this is exactly what my work is built around.
Because you deserve more than generic advice. You deserve a plan that actually sees your brain.
