I’ve worked with Lou for over a year now and can’t recommend her highly enough. I completed the original Performance Health programme and was able to cure years of IBS symptoms following Lou’s blood work assessment and recommendations. At the end of my original 6-months I was feeling so good that I did a new set of blood tests and also the Dutch test, to learn even more about what makes my body tick. The Dutch test was something that I wish I’d done years ago- BEFORE I started experimenting with different forms of HRT and basically just trying to guess!!

Performance Health has really helped me to learn about my body, which foods work best and which supplements I actually need. I was previously spending so much money on supplements that were probably a complete waste of time. I wish I’d found this program sooner as it’s been the best money I ever spent.
– Tom P, Cornwall
Lou’s bloodwork analysis is incredible. I’d had multiple blood tests done by my GP, and they were constantly telling me everything was fine even though I was feeling crap. Brain fog, bloating, irritability, joint pains… You name it, I had it. Lou was able to tie together how my different symptoms were linked and came up with a plan of targeted supplements. I felt a huge shift in my mental energy after the first few weeks. I really do feel so much better. I’ve been recommending Performance Health to all of my colleagues.

You’re Doing the Right Things — So Why Do You Still Feel Off?
You exercise regularly.
You eat well.
You care about your health.
Yet something doesn’t feel right anymore.
You might recognise yourself here:
- Energy that never fully returns, even with rest
- Brain fog affecting focus, memory or motivation
- Training plateaus or slower recovery than expected
- Weight gain or body composition changes that don’t make sense
- Hormonal symptoms creeping in — poor sleep, mood changes, cycle disruption
- Digestive issues, bloating or inflammation
- Repeated reassurance that your blood tests are “normal”
You’re still functioning.
You’re still coping.
But it feels harder than it should.
And deep down, you know there’s more going on
The Performance Health Difference: Objectivity and Personalisation
Why “Normal” Blood Tests Don’t Tell the Whole Story
Standard medical testing is designed to diagnose disease, not to explain why capable, driven people feel chronically underpowered.
If your results fall within broad population ranges, you’re told everything is fine.
But performance, recovery, hormonal balance and long-term health decline long before disease appears.
Performance Health® uses functional blood work analysis, meaning:
- We assess patterns, not single markers
- We look at how systems interact, not isolated organs
- We identify early dysfunction before it becomes a diagnosis
- We translate complex data into clear, practical action
After more than 20 years working with pain, injury and performance and seeing how often symptoms don’t fit neatly into a single box, I developed my Performance Health® Method.
It exists to answer one simple question clearly:
Why does your body feel stuck — and what will actually move it forward?

FAQ's
No. Most clients are active, capable people who simply know they shouldn’t feel this tired, foggy or flat.
Yes. That’s usually exactly why it helps.
Many people notice improvements within 2–4 weeks. Hormonal, gut and metabolic changes typically evolve over the full 3-month protocol.
You’ll have the knowledge and tools to continue independently, with the option of follow-ups and further testing if you choose.
Performance Health is designed to be a self-guided program giving you all of the tools you need to succeed. However, you can also choose to bolt-on follow-up calls for extra support. As a Performance Health Client you get priority access to Lou’s online consultation diary.
