About me
I’m Gráinne (the girl with the name no-one (except the Irish) can pronounce
I'm a hormone and metabolic nutritionist who helps busy, frustrated women escape hormone chaos and feel like themselves again.
But that’s not how I started out.
I moved to Brussels straight out of university. I spent a few years working for the European Commission before joining my brother’s business when my contract ended. At first, things were great. But as I took on more responsibility, the pressure mounted - and my body began to pay the price.
By my late 20s, I had a growing sense that something wasn’t right.
From the outside, I was “successful” - running a 7-figure business, managing a team, driving growth, spinning all the plates. But behind the scenes? I was running on caffeine, adrenaline, and sheer willpower. Twelve-hour days, seven days a week.
No surprise I was exhausted and struggling to get pregnant.
Reluctantly, I went to my GP and was referred on to a fertility specialist. I spent hours under fluorescent lights in sterile waiting rooms, answering cycle questions, getting bloodwork, ultrasounds, laparoscopies - hoping for answers.
But one by one, the tests came back “normal.”
I was diagnosed with idiopathic infertility (infertility of no known origin) and offered treatment anyway - no context, no curiosity. Just protocol.
Something about it felt wrong. Like I was being handed a one-size-fits-all plan, when I knew in my gut that my body needed something different. I wasn’t just tired - I was depleted. And no prescription was going to fix that.
So I started thinking differently. Holistically. I read, researched, cooked more nourishing meals, bought a juicer, experimented with supplements, worked with holistic practitioners, began healing my stress, and learned to delegate.
Little by little, my energy returned.
I stopped needing sugar to get through the afternoon. I didn’t crave wine to unwind. I felt clearer, calmer, and more like myself again.
A few months later, I began fertility treatment - and got pregnant.
That’s when it hit me: The fix for my problem wasn’t available on prescription
Like many women building careers, families, and futures on fumes, I didn’t need a diagnosis as much as I needed someone to connect the dots: between my symptoms, my bloodwork, my lifestyle, my stress, and my nutrition.
It would take a few more years - and another heartbreak - before that truth fully landed.
After my dad was diagnosed with terminal cancer, my body collapsed again: burnout, another failed attempt to conceive, and the same cycle of confusion and frustration. That was the moment I knew something had to change - for good.
I left the business. I focused on healing. And once I was on my feet again, I retrained and eventually built the online practice I wish I’d had:
A place for real, personalised support - grounded in science, advanced hormone testing, compassionate coaching - and the radical (but true) idea that food and lifestyle are medicine.
‘I am 14kgs lighter, full of energy, with no signs of inflammation in my body. My digestion is better, my skin glowy and, apart from that, I have a great routine to balance out work and me time. What I appreciate most about Gráinne’s approach is that it is scientific and personalised - the process, supplements, and food are tailored and personalised based on the results of very thorough tests, so responding to each individual’s personal needs, from a holistic perspective. I wholeheartedly recommend it! Alexandra
Some more random facts about me below 👇🏻
Before changing careers, I had a different job in food which I loved. I sucessfully managed my brother’s (@jackoshea) butcher shop in Brussels. My brother was always a step ahead of the trends, bringing back inspiration from his world travels back to the businesses, and gaining him a reputation as Europe’s best butcher at the time. That time in my life taught me life long lessons, and all sorts of transferable skills!
My other brother (@osheasbutchers) also went into the family business and is an award winning butcher, based in London.
Whereas my sister is a professional make-up artist, @ciaradoesmakeup, who has worked with industry legends including Madonna, Gwendoline Christie and Cole Sprouse. And no, I didn’t inherit any of her talents!
I love what I do and always wanted to work in a career that helped people. I hesitated between studying Psychology and Criminology when I left school, opting for Psychology. Turns out I was pretty 💩 at statistics, so I changed degrees and have a BA in Language Studies instead!
I speak French though choose not to work in it because I suffer from a bad case of perfectionism and don’t like the thought of getting things wrong!
My superpower is probably in the kitchen. I’m not fazed by cooking, and can knock up something fast and tasty, whatever tastes, peculiarities or allergies are involved
Unlike most Irish people, I can’t drink alcohol for nuts - that and mould are like kryptonite for my delicate disposition
I’m a qualified clinical Nutritionist and Naturopath but I was hungry for something more scientific which led me to discover functional medicine ! If you don’t know what this means, click on the link. I’ve written a page all about it.
I work as an integrative practitioner. Your health and safety are my priorities. If you’ve got something that requires medical attention, then the Docs office is where I’ll be sending you!
I’m human, I sometimes like to eat crap too - just don’t tell my kids!.
I’m beyond slightly obsessed by medical dramas and true crime. ER was my favourite medical series of all time. I often fall asleep listening to Anatomy of a murder or the Crime Junkie podcast. No surprise that the kind of cases I love getting my teeth stuck into are the hard-to-crack ones
