Hi! I’m Mark Killick

I’m a Men’s Health Functional Nutritionist

You’ve been told your results are “normal.” But you don’t feel normal. You’re exhausted, your digestion is playing up, your waistline is expanding – and you can’t shake the nagging feeling that something isn’t right.

At Mark Killick Health, I specialise in men’s health as a functional nutritionist, using evidence-based nutrition and lifestyle medicine to get to the root of what’s holding you back. Whether you’re dealing with low testosterone, poor circulation, type 2 diabetes, digestive problems, erectile dysfunction, or simply want to protect your heart health for the long term – this is where real change starts.

No guesswork. No generic advice. Just a clear, personalised nutrition and lifestyle plan built around you.

Testimonials

I’d put my low energy and flat mood down to just getting older. Within eight weeks of working with Mark, my energy was back, my sleep improved, and honestly I felt like myself again. Wish I’d done this five years sooner.

James - 47

I was sceptical nutrition could make that much difference to how I felt day to day. Three months in, my afternoon crashes are gone and I’m back to training properly. Mark took the time to actually understand my bloods and lifestyle rather than giving generic advice.

Andrew - 52

Bloating and stomach pain had become normal for me – I just lived with it. Mark helped me work out what was actually driving it, and within a few weeks of the changes we made, I had my first properly comfortable month in years.

Steve -39

I went to my GP feeling dismissed and was told it was just my age. Mark took my symptoms seriously and built a nutrition plan around my hormones and lifestyle. My energy, sleep and mood have all improved more than I thought possible.

Claire - 51

I’d spent years following generic healthy eating advice that never quite worked for me. Once Mark used my genetic test results to tailor a plan specifically to my biology, things finally started to click – better energy, better digestion, and results I could actually measure.

Rachel - 45

The brain fog, the night sweats, the weight that wouldn’t shift no matter what I did – I felt like I lost control of my own body. Mark helped me understand what perimenopause was actually doing to my hormones and gave me a plan that worked with my body, not against it. I feel like myself again.

Sarah - 48

Getting my DNA results back and having Mark walk me through what they actually meant for my body was eye-opening. We adjusted my diet based on how I actually process certain nutrients, and the difference in how I feel has been significant.

Michael - 41

I’d tried cutting out food after food on my own with no real improvement. Working with Mark gave me an actual plan based on what was going on in my gut, not guesswork. Six weeks in and the discomfort that had been there for over a year had settled right down.

Paul - 44

Why men’s health nutrition is different

Why men’s health nutrition is different

Men face a distinct and often underserved set of health challenges. Cardiovascular disease remains the leading cause of death in men in the UK. Type 2 diabetes is more common in men and frequently diagnosed too late. Low testosterone affects an estimated one in four men over 30, yet most never connect their symptoms to nutrition. And conditions like erectile dysfunction, IBS, and chronic fatigue are routinely dismissed – despite having clear, addressable dietary and lifestyle drivers.

As a functional nutritionist specialising in men’s health, I look at how your hormones, gut, cardiovascular system, and metabolism are all connected – and build a plan that addresses the underlying causes, not just the surface-level symptoms.
