Thirteen years in, you notice which patients are still doing well a decade later. What they share is disappointingly unglamorous.

They move most days, and it's boring movement. A walk, a ride, a garden. Not a program they started a fortnight ago — something they've done long enough that skipping it feels odd.

They kept their muscle. If I had to pick one physical thing that separates the seventy-year-olds still doing what they want from the ones who aren't, it's that.

They protect sleep like it's an appointment. Not perfectly. But they notice when it slides and they act, rather than waiting to get used to it.

They have people. Not a big circle — a real one.

And they stayed curious. When something changed in their body, they wanted to know what was driving it, instead of stacking one more thing on top and hoping it settled.

None of that is a supplement. Almost all of it is a decision repeated for decades.

Sometimes the supplement is the reason the anxiety got worse.

Magnesium gets all the attention, and it helps plenty of people. But when someone tells me their anxiety climbed after starting something, I'm usually looking at three things.

Copper and zinc compete for absorption. Push one hard on its own for months and you can quietly drag the other down. A high copper-to-zinc ratio has been associated with the wired, restless, can't-settle version of anxiety — the kind that doesn't respond the way people expect to the usual calming supplements.

B6 matters because it's a cofactor in making GABA and serotonin. Low B6 can leave that production short. But B6 is also the one where more isn't better — sustained high intake carries its own nerve-related risks, and it's one of the more common over-supplemented nutrients I see.

The useful part: plasma zinc, serum copper, and an active B6 marker will tell you which direction to move, rather than guessing and hoping.

If a supplement made things worse rather than better, that's information. It's worth testing rather than pushing through.

Everyone calls it the 3pm crash. It isn't one thing.

A. Hungry, shaky, a bit irritable — and completely fine ten minutes after you eat. That's a blood sugar pattern.

B. Wired but flat, coffee doesn't land, then a second wind at 9pm you never asked for. That's a cortisol rhythm pattern.

C. Heavy and slow across the whole afternoon, cold hands, and nothing you eat or drink shifts it. That's worth checking thyroid.

The same symptom, three different drivers, three different sets of testing.

A, B, or C — which one is yours?

"I think I'm just getting older."

Maybe. But four things account for most of the focus complaints I hear, and all four are measurable.

1. Blood sugar swings. A sharp rise after a carb-heavy meal, a sharper fall an hour later, and a foggy stretch you blame on the afternoon. Fasting insulin and HbA1c tell you more here than glucose alone.

2. Low iron stores. Ferritin can sit low while a full blood count looks completely normal. Concentration and word-finding often slip before anyone thinks to check.

3. Sleep debt. Not one bad night — months of six hours that felt survivable. Attention and working memory measure worse long before you feel obviously tired.

4. An underactive thyroid. Slow recall and slow word-finding are frequently the first thing people notice, ahead of weight or cold hands.

Ageing is real. It's also the explanation people reach for when nobody has looked at the four things above.

Which one sounds most like your afternoons?

For every two days of appointments, I spend about a full day preparing.

People are sometimes surprised by that. It's the actual work, not admin.

A set of results isn't a scorecard you read top to bottom. The useful information is in how markers sit together — and how they sit next to what you've told me about your sleep, your cycle, your energy, and the year things changed.

Reference ranges help, but they describe what's common in the people who got tested. They don't describe what's optimal for you, and they don't show me what's moved since last time.

So before you sit down, I've read the research relevant to your specific pattern, mapped your history against the numbers, and worked out what I'd want to rule out before suggesting anything.

By the time we're in the room, the thinking is done. That's the part you're actually paying for.

Five gut habits I see people paying for every month that the evidence doesn't really support.

1. A daily probiotic for everyone. Probiotics are strain-specific. The strain studied for IBS bloating is not the strain studied for post-antibiotic recovery. Taking a generic multi-strain because it's on the shelf is a habit, not a plan.

2. Cutting every carb. Fermentable fibre is what your bacteria turn into butyrate, the short-chain fatty acid your gut lining runs on. Long-term low-carb often quietens symptoms while quietly shrinking diversity.

3. Cleanse kits. No baseline, no target, no way to know if anything changed. Money spent on a feeling.

4. Enzymes for bloating. Sometimes right. Often the actual driver is motility, low stomach acid, or bacterial overgrowth further up, and enzymes don't touch any of those.

5. Elimination diets with no end date. Every food removed is fuel removed. Reintroduction is the part that gets skipped, and it's the part that matters.

What I'd rather see: work out what's actually happening first (stool testing, breath testing, a proper history), then spend money on the thing that matches the result.

Which of these five have you tried?

I've built something I've wanted for my patients for a long time. A digital results page: a clear, visual snapshot of their blood work that lives on their phone like an app. It shows your standard pathology ranges, my functional ranges (the tighter targets I actually aim for in clinic), and exactly where your results sit against both. Underneath, there's a plain-English summary of what we found and the plan from your consult. No more squinting at a PDF full of numbers with no context. You can see at a glance what's optimal, what's borderline, and what we're working on together, any time you want. This is what root-cause care should feel like: your data, made clear, and yours to keep.

Some of the most useful things patients tell me start with an apology. 'This is probably nothing, but...' The afternoon crash they've had for years. One patch of broken sleep. A nail that changed. Here's why I never wave those away: small symptoms are often the body's first flag, the quiet signal before something gets loud. They're rarely dramatic, which is exactly why they get ignored, and why they're worth attention. Caught early, most are far easier to work with. If there's a 'small' thing you've been putting up with, it's not too small to mention. This is why I listen to the whole story.

Ashwagandha is everywhere right now, sold as the answer to stress. Does it work? Partly. A 2025 meta-analysis found it can lower cortisol in stressed adults, so there's a real effect there. But it's a lever, not a fix. It nudges one part of a system with many drivers, and for some people, including certain thyroid and autoimmune cases, it's the wrong choice. The more useful question is why your stress system is stuck switched on in the first place. That has causes we can test for: blood sugar, sleep, nutrient status, and the load you're carrying. If stress has been running the show, it's worth understanding what's driving it. Book a consultation or take our free assessment:

It's deep winter in Adelaide, and vitamin D is the one nutrient most of us are quietly running low on right now. Short days and less time outside mean many adults sit below the optimal range by late winter, and it shows up in more than your bones. Low vitamin D can look like flat mood, restless sleep, and catching every bug going around. The catch: a result can land inside the 'normal' lab range and still be well below where you'd want it. A simple blood test shows where you really sit. Worth knowing before spring. Does this sound familiar?
