Tania Lewis, BHSc (Naturopathy), BN, a naturopath for women whose energy, digestion and sleep have changed.
I see clients in Rutherglen and Yarrawonga, and online across Australia.
Tired in a way sleep doesn’t fix
You go to bed at a reasonable hour. You eat reasonably well. And by mid-afternoon there’s nothing left.
You’ve stopped mentioning it, because the answer is always the same.
Your bloods are fine. You’re just busy. It’s your age.
It might be all three. But tired most days, not just some, is worth looking at properly.
Why normal bloods don’t settle it
A result inside the reference range tells you that you don’t have a disease that range was built to catch. It doesn’t tell you where you sit within it. You can sit at the bottom of normal for years and feel every bit of it.
A ferritin sitting at the very bottom of the range still gets marked normal. So does a fasting glucose that’s fine while insulin is quietly climbing. On paper, nothing’s wrong, but you’re still tired every day.
“Your doctor is looking for disease. I’m looking for patterns and dysfunction.”
That’s not a criticism of GPs. It’s a different job. I work alongside your GP, not instead of them.
Fatigue is not always iron
Iron is the first thing most people check. Fair enough. But when iron comes back fine and you’re still flat, the questions keep going.
What about B12? Are you eating enough protein? Can you actually digest it? Do you have enough stomach acid to absorb what you’re eating?
And when iron is low in a woman who eats well, the next question is why.
- Stomach acid. Iron in food is bound up. Stomach acid helps release it. Acid production tends to fall with age, and reduced gastric acid is one of the factors that makes minerals harder to absorb as we get older (Welham et al., 2024). Long-term use of acid-reducing medication is also associated with lower iron absorption (Sekar Lakshmisai et al., 2025). If you take one, don’t stop it. Talk to your GP.
- Inflammation. When there’s inflammation, the liver makes more of a hormone called hepcidin. Hepcidin closes the door on iron absorption from the gut (Nemeth & Ganz, 2022). Low-grade inflammation that runs for months keeps that door half shut.
- What you take with meals. Calcium carbonate is alkaline. It buffers the same stomach acid you need for iron and B12.
A client came in on calcium carbonate with low iron, which raised a question about stomach acid.
This is also why topping up iron because you’re tired isn’t harmless. Too much iron is its own problem.
Test, don’t guess.
Are you eating enough protein?
Most women I see think they are. Many aren’t.
Protein needs rise with age, because muscle gets harder to build. A 2025 review reports that in the United States, half of women over 71 don’t eat enough protein (Harris et al., 2025).
Protein also stabilises blood sugar. That matters for the next part.
The 3pm slump
Toast, cereal or a coffee on an empty stomach sends blood sugar up fast, then down hard a few hours later. Your energy follows it down.
Protein at breakfast slows the rise, so the fall is gentler. From what I see in my clinic, the 3pm crash is often a breakfast problem, not an afternoon one.
Where your thyroid fits
Often, the results women bring in include ferritin and TSH, and not much else. I want to see the whole iron picture, B12, active B12, fasting insulin, vitamin D and a full thyroid panel. Ferritin rises with inflammation, so on its own it can look fine when iron isn’t. Active B12 shows how much your cells can actually use. Fasting insulin can rise while glucose still looks fine. TSH alone doesn’t tell me whether you’re converting thyroid hormone into the active form your cells use.
More on that on my thyroid health page.
What about menopause?
It can be part of the picture. Fatigue, broken sleep and changes in blood sugar regulation often show up together around menopause. But a life stage tells you when something started. It doesn’t tell you what’s driving it. That’s what I look for.
What I look at
Before we meet, I ask for any blood results you’ve had, old ones included, and read them against optimal ranges, not just the reference range. If you haven’t had tests for a while, we’ll work out which ones are worth doing.
In the room, we go through:
- Energy across the day, and when it drops
- What you eat, when and how much
- Digestion, including reflux, bloating and bowel habits
- Sleep, stress and your history
- Every medication and supplement, including anything taken with meals
If there are gaps in your bloods, I’ll tell you which tests would fill them, and why.
You’ll receive a written plan: what we’re starting with, why each change is there and what I’m deliberately leaving until later. Food first, with supplements alongside where they’re clearly indicated.
How long does it take?
Care may take three to six months, sometimes longer. There’s no overnight fix or magic pill, and the changes are yours to make.
Red blood cells live around 120 days. That’s why, if you retest, it’s at the end of care, not partway through.
And the order matters: Reset, Rebuild, Restore. Driving repair before inflammatory load has come down can produce flares. Along the way, I track energy, sleep and stress out of ten, so you can see what is and isn’t shifting.
“Most women who come to me have been unwell for years, not weeks. I’m not going to undo that in one consult, and I won’t pretend otherwise.”
Frequently asked questions
How much does it cost?
An Initial Clinical Assessment is 60 to 75 minutes, $220. Follow-up Consultations are 30 to 45 minutes, $150. Pathology and supplements are billed separately, at your cost.
Do I need new blood tests?
Not necessarily. If you have recent results, send them and I’ll read them before we meet. If you haven’t had tests for a while, we’ll work out which ones are worth doing, and why.
Should I just take an iron supplement?
Not without knowing your levels. If your iron is fine, extra iron won’t help your energy, and too much is its own problem. If it’s low, the more useful question is why.
Do I need to stop my medication or HRT?
No. I never ask anyone to stop prescribed medication. It’s part of your picture, and I factor it in. If anything I find needs a conversation with your doctor, I’ll tell you.
