HELLO! I am known as the brain health nutritionist due to my professional expertise in BRAIN HEALTH, mental health, stress, neurodivergence, hormonal balance, gut health, weight-loss, emotional eating (20 years in clinical practice) & because of my own health journey - find out more below.
Qualifications, What I Can Do For You & My Story
Qualifications
I hold a BSc Hons degree in Nutritional Medicine (2006) and am a registered member of the British Association for Nutrition & Lifestyle Medicine (BANT), which sets the standard of excellence in science-based personalised nutrition and lifestyle medicine.
Initially after qualifying, I built up a broad expertise which gave me a great foundation in all areas of health. I then specialised in my chosen areas such as brain health, continually throwing myself into the research to ensure I provide evidence-based recommendations.
I have extensive experience in female hormonal health, including conducting a small study on the effects of diet and supplementation on premenstrual syndrome (PMS). Alongside my clinical practice, I also spent five years as the nutritional expert for a London-based food supplement company, gaining further expertise optimising health via personalised nutrition and supplementation. I'm also an experienced health coach providing additional support in lifestyle medicine and behaviour modifications (such as sleep optimisation, stress management and exercise).
I help people navigate their health concerns with confidence by optimising and stabilising their brain and mental health—saving them time, money, and unnecessary stress along the way. As a busy 51-year-old working mum of two preteen/teen boys, I understand the high demands of modern life. That’s why my plans are always practical, sustainable, and tailored, alongside supportive health coaching. I also share lifestyle hacks that keep me and my brain healthy while reducing comfort eating.
My goal is to empower people—whether you’re seeking to protect and optimise your well-being, or suffering the adverse effects of chronic illness or stress, wanting to manage your weight, or improve your relationship with food. I also see people with very challenging health issues such as dementia or mental illness who need comprehensive support from an calm, clear, experienced practitioner.
Chronic stress may need to be addressed as it disrupts brain function, mood, resilience, hormonal health, vitality, pain perception, metabolism, and longevity—and it often increases cravings. Stress also negatively affects the gut, and a healthy gut is essential for a healthy brain, and vice versa (via the gut brain axis and the gut microbiome). Supporting gut health is fundamental to brain function.
My approach is warm, compassionate, down-to-earth, and non-judgemental. I can also work with your GP or consultant to provide integrated healthcare, creating a plan that’s safe alongside medication where appropriate.
I have a family member with Alzheimer's, who has really benefited from cognitive nutrition. This has further increased my interest in brain health and the powerful effect of nutritional medicine on cognitive function.
But I first decided to undertake a nutrition degree (my second degree) in my late 20’s when I was feeling miserable due to severe weight gain I couldn't shift from polycystic ovarian syndrome (PCOS). And even before that, I had (undiagnosed) ADHD & my life had been blighted by PMDD (the two often co-exist) - premenstrual dysphoric disorder which robbed me of a week of every month since my teens. None of which doctors were able to help with.
Thereafter, mental health issues blighted my health. In 2007, whilst also completing my nutrition training, I took on too many simultaneous projects - typical behaviour of an impulsive ADHD brain, doing up our first property and organising our wedding. And with a strong genetic vulnerability, I had a severe mental health crisis & burnout. I experienced depression, anxiety, culminating in 6 weeks being bedridden with post-viral fatigue & fibromyalgia (a chronic pain disorder).
Finally, in 2010, after 3 preceding miscarriages, plus a very traumatic pregnancy & delivery, I experienced an acute postnatal mental illness, being hospitalised ten days after my first son was born (unfortunately bipolar runs heavily on one side of the family.)
I have overcome these traumas and debilitating struggles, with no more PMDD - despite being in the midst of the perimenopause. And in my spare time, I captain a netball team. See the blog for more on my personal story. And for my experience with ADHD- see here.
It’s become my life’s passion to help people get better with tailored evidence-based nutrition, functional medicine & nutrigenomics using all my clinical & personal experience, plus a constant thirst for knowledge.
