I take a small number of Flagship clients at any one time, because every plan is personally designed.

Start with the Benchmark and decide later: if you upgrade after your results call, what you've paid comes off the Flagship investment. Places are limited, so if you already know the Flagship is what you want, book the call first.

Who I work with

Different bodies. Different goals. The same question underneath.

The people I work with don't fit one box. What they share is a version of the same sentence: something has shifted, and nothing I try quite fixes it.

  • Training hard, recovering slowlyGym-goers, runners, cyclists and weekend competitors who've plateaued. You still push hard, but the bounce-back is gone.
  • Perimenopause and beyondWomen navigating hormone shifts who want to understand what's actually changing, and support their body properly, with or without HRT.
  • Running a business, running on emptyFounders and professionals whose diary outpaces their energy. Brain fog and afternoon crashes are quietly taxing every decision.
  • Not a gym personYou don't particularly train, and you don't want to. You just want steady energy, clearer thinking and a body that doesn't ache by default.
  • Brain fog and flat energySharp people who feel like the edge has gone. Concentration, memory, motivation and mood aren't what they were, and coffee is doing more of the lifting.
  • Feeling like this is itYou've started wondering if feeling average is simply the price of being over 40. You aren't ready to accept that. Neither am I.

Whatever your goal, the starting point is the same. Find out what your body actually needs. Then do the right things, in the right order.

The interpretation makes the difference

Why this goes beyond a normal blood test.

The value is in understanding the results. I review over 80 markers together, alongside your symptoms and goals, and explain what to focus on first.

Markers read together

Low energy isn't always an energy problem. Gut symptoms aren't always a food problem. My Synergy Patterns® analysis reads the ratios and relationships between markers, so I can see how your body systems are actually functioning, not just whether each marker is technically normal.

Optimal ranges, beside the standard ones

Your report shows the laboratory reference range and the functional range used in our analysis side by side. I explain the findings in the context of your Blueprint, with clear priorities and starting steps.

Read in the context of you

Your Performance Health Blueprint brings in your symptoms, lifestyle, sleep, stress, food and goals. The bloods are read against what life is asking of your body, so the plan becomes specific to you.

The analysis behind your report is a method I've built over 21 years in practice, and I check and sign off every report myself.

About Us

Functional bloodwork, read properly.

  • Functional bloodwork specialists
  • Synergy Patterns® analysis
  • UKAS accredited laboratory
  • Trusted by clinics across the UK

Performance Health works with the people other practitioners struggle with: complex cases, things that don't respond to standard treatment, clients no one has been able to help. That work led us deep into bloodwork, gut health, immunology and epigenetics.

At the centre of every report is our Synergy Patterns® analysis, developed by our founder, bloods specialist Lou Nicholettos: patterns across over 80 markers, read against optimal ranges and in the context of you. The cross-marker patterns, nutrient picture, inflammatory signals and hormonal balance only become visible when the markers are read together. We take a small number of clients at a time, because every plan is personally designed and every report is checked and signed off by our team before it reaches you.

The Flagship Programme

Answers first. Then the plan. Then someone in your corner.

Most people who come to me have already tried the sensible things. What they've never had is a proper explanation of their own body, and a plan built from it. The Flagship gives you both, and then I stay with you while you do it.

  1. Your starting point

    Advanced analysis of over 80 markers, read against optimal ranges, and my Synergy Patterns® analysis of how they relate to each other and to you. This gives us a starting point for your personalised plan.

  2. A second advanced test

    We add one more test chosen for you: genetics and epigenetics, a stool analysis, or the DUTCH test for a detailed look at your hormones. With both sets of results I write your full protocol to cover the four months: food, lifestyle and supplements, step by step.

  3. Guided, and measured

    I guide you through it with daily WhatsApp support as you need it and fortnightly calls with me, adjusting the plan as you respond. We retest your Blueprint at 8 and 16 weeks so we can map your progress.

  4. The right order

    Your plan follows the six-step Performance Health Framework, so each step is doing its job before the next one starts. We prioritise the changes that fit your findings and goals, then review how you respond.

The framework

The right steps, in the right order.

Your plan is built around the six-step Performance Health Framework. Each step has to be doing its job before the next one can. Nourish is the foundation and the highest priority; everything above sits on that layer.

  1. 01NourishThe foundation and highest priority. Nutrients, sleep, nervous system, genetic predispositions.
  2. 02DigestBeyond the microbiome. Stomach acid, enzymes, bile, gut lining, beneficial flora and pathogens.
  3. 03ClearDrainage, detoxification and elimination. Liver, kidney, bowel, lymphatic, hormone metabolism.
  4. 04ResolveInflammation is normal. Failing to resolve it isn't. CRP, hs-CRP, NLR, fibrinogen.
  5. 05AdaptHormones and energy, in conversation. Metabolic and hormonal regulation, tissue repair, recovery.
  6. 06PerformSharper, stronger, ageing slower. Mental clarity, sustained productivity, sports performance, longevity.

Honest truth

This isn't for everyone.

I'm selective about who I work with, because the programme only works if you're ready to do the work.

This is for you if

  • You're ambitious in work, sport or life, and you know your body is becoming the bottleneck
  • You've been told the bloods are "normal" but you can feel something is off
  • You're done guessing and ready for a precise, evidence-based approach
  • You're willing to follow a personalised protocol and actually make changes
  • You want to feel as good as you look on paper

This isn't for you if

  • You're looking for a quick fix or a magic supplement
  • You aren't willing to make changes to how you eat, sleep, train or recover
  • You want someone to tell you what you want to hear
  • You're after a generic programme you could find for free online
  • You aren't ready to take your health as seriously as the rest of your life

Common questions

Before you get started.

How is this different from a standard blood test?

The Benchmark combines over 80 bloodwork markers with your Blueprint health assessment. I review the markers together, show the laboratory and functional ranges side by side, and explain your priorities in a personally reviewed report and results call. It complements medical care and does not replace tests or advice from your GP.

What's the difference between the Benchmark and the Flagship Programme?

The Benchmark is the starting point: over 80 markers read together, against optimal ranges, in the context of you, with your Blueprint, a report with your score and three priorities, and a results call with me, so you understand what's going on and where to start. It's £599 and you order it online. The Flagship Programme is the one I recommend if you're committed to getting results: a full nutrition and supplement plan covering four months, adjusted as we go, fortnightly calls, and me guiding you through the whole process on WhatsApp. If you're not sure which is right for you, book a free strategy call and we'll work it out together.

Can I start with the Benchmark and upgrade to the Flagship?

Yes. After your results call you'll be offered the option to upgrade to the fully guided Flagship Programme, and what you've paid for the Benchmark comes off the Flagship investment. Places are limited, so if you already know the Flagship is what you want, book a free strategy call first.

Where do I get the blood draw done?

I arrange everything through a UK-wide phlebotomy network of more than 290 partner clinics. You attend a local clinic at a time that suits you. The sample is processed at a UKAS-accredited laboratory.

I don't live near you. Does that matter?

Not at all. The Flagship Programme runs entirely online. The blood draws happen at your local clinic, the calls happen on Zoom, and the plan comes to you digitally. I work with clients across the UK. If you're outside the UK, ask first: it depends on the country.

Which advanced test will I get on the Flagship?

One of three: Genetics + Epigenetics, the DUTCH Hormone Test, or a GI Map Stool Test. We choose it together during your initial consultation, based on your symptoms and goals, so the test that joins your plan is the one that will add the most precision for you.

I'm busy. Will I have time for this?

The whole programme is designed for busy people. Your personalised plan integrates into the routines you already have, it doesn't replace your life. Calls with me are short and high-impact, fortnightly across four months. There are no group calls you have to attend at fixed times. The whole point is to give you back time and energy, not take it away.

Do you work with clinics and practitioners?

Yes. Our clinic partner programme is for health and wellness clinics, with bloodwork interpretation and the results call handled by Performance Health. Our practitioner route is for nutritionists and functional medicine practitioners who already include bloodwork in their programmes and want advanced interpretation for their clients. Explore the two routes.
