ABOUT ME
I’m Gráinne.
A hormone nutritionist who helps busy, frustrated women escape hormone and metabolic chaos and feel like themselves again.
But that’s not how I started out.
MY STORY
By the time I hit my late 20s, I had a growing sense that something wasn't right. On paper, I was successfully running a 7-figure business, managing a team, driving growth, spinning all the plates. 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 to a fertility specialist. I spent hours under fluorescent lights in sterile waiting rooms - bloodwork, ultrasounds, laparoscopies - hoping for answers.
One by one, the tests came back "normal."
I was diagnosed with idiopathic infertility (infertility of no known origin), and that's where curiosity stopped, and a treatment plan was put in place.
Something about it felt wrong. But I was tired, depleted, and desperate to start a family - so I signed on the dotted line.
To give myself the best possible chances, I started reading and researching around the subject, and eventually the penny started to drop as I connected the dots between my hormone levels and fertility, and my stress, diet, and lifestyle.
So I cooked more nourishing meals, took supplements, worked with holistic practitioners, began managing my stress, and learned how to delegate better.
A few months later, I started to feel like myself again.
My energy returned. I stopped needing sugar to get through the afternoon and wine to unwind.
I got pregnant on the first round of fertility treatment and thankfully had an easy pregnancy, birth and post-partum period.
So I retrained and built the practice I wish I'd had access to: a place for personalised, integrative hormone support - grounded in science, advanced testing, and compassionate coaching - and of course the radical (but true) idea that food and lifestyle are medicine too.
Reconnecting with the kitchen, where my real turnaround started.
Food and Lifestyle are medicine too.
THE IDEA MY WHOLE PRACTICE IS BUILT ON
"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!"

OFF THE CLOCK
Some more random facts about me👇
Before changing careers I managed my brother's (@jackoshea) butcher shop in Brussels. He was named Europe's best butcher at the time, and it taught me lifelong lessons and all sorts of transferable skills.
I speak French, though I choose not to work in it because I have a bad case of perfectionism and hate the thought of getting things wrong.
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!
Unlike most Irish people, I can't drink alcohol for nuts. That and mould are like kryptonite for my delicate disposition.
I'm beyond slightly obsessed with medical dramas and true crime. ER is my all-time favourite, and I often fall asleep to the Crime Junkie podcast. No surprise the cases I love getting my teeth into are the hard-to-crack ones.
I have a BA in Language Studies. I started in Psychology, but it turns out I was pretty rubbish at statistics, so I switched.
