Welcome to your health, rewritten
Supporting Families, Athletes, and Minds Under Pressure - Through the Science of You.
Discover how your genes influence everything from how you process nutrients to how you respond to stress — and what to do about it. Julia helps you decode your DNA to create personalised, practical strategies for vibrant health and wellbeing.
Meet Julia
Hi there, I’m Dr Julia Parker, a GP for over 7 years and a certified Nutrigenomics Practitioner, trained by Lifecode Gx®, a leader in DNA-based health. I combine cutting-edge science with a warm, supportive approach to help you understand your genetic blueprint - and use it to support your health goals.
Whether you’re dealing with fatigue, inflammation, hormone imbalances, or simply want to future-proof your wellbeing, I’m here to help you work with your body, not against it.
What is nutrigenomics?
Nutrigenomics is the study of how your genes interact with your diet, lifestyle, and environment - and how those interactions can affect your health, mood, energy, and wellbeing.
While your DNA doesn’t change, the way your genes express themselves can be influenced by everyday factors like what you eat, how you manage stress, how well you sleep, and even your exposure to toxins. That means you’re not stuck with your genetic hand - you can make informed choices that help your body function at its best.
Through a simple saliva test and a personalised report, nutrigenomics can help answer questions like:
Why do I react differently to certain foods or supplements?
Why do I feel anxious, foggy, or low - even though I “should” be fine?
Why don’t standard health or fitness plans work for me?
What can I do now to protect my long-term wellbeing?
This isn’t about generic advice. It’s about your body, your data, your roadmap - so you can make small, science-backed changes with a big impact.
Who is this for?
For Parents of Neurodiverse Children
You’re trying to do the best for your child - but the advice is conflicting, the systems are overstretched, and it’s exhausting to go it alone.
DNA testing can help you understand the underlying nutritional and neurological factors that may be affecting your child’s mood, focus, sleep, or sensory responses. It can also give you insights into your own stress response, resilience, and emotional regulation - so you can support them from a stronger place.
Reports like the Nutrient Core and Nervous System can help identify areas where nutritional or environmental support could make a real difference - giving you practical strategies and greater peace of mind.
For Adults Struggling with Anxiety, Mood, or Hormones
If you feel like something’s “off” but haven’t found clear answers, your DNA may hold the missing piece.
Mood swings, low energy, poor sleep, or hormonal issues are often influenced by your genes - but they’re also shaped by your environment. Nutrigenomic testing helps you understand how your body metabolises key nutrients, manages stress, and balances hormones, so you can work with your biology, not against it.
Reports like Methylation, Hormones, Thyroid Balance, or Histamine Intolerance offer insights that can lead to better energy, mood stability, and overall wellbeing - without guesswork.
For Athletes and High Performers
You’re already doing the work - now it’s time to train, recover, and fuel yourself with precision.
Nutrigenomic testing can reveal how your body uses energy, responds to stress, processes inflammation, and recovers from intense activity. Whether you’re training for performance or just want to feel and function at your peak, these insights can help you tailor your approach for faster recovery and long-term resilience.
The Athlete Report, Metabolics, and Detoxification panels are ideal for building a smarter, science-backed strategy for endurance, sleep, focus, and injury prevention.
Our DNA Reports
Every person is different. That’s why cookie-cutter advice so often falls short. With DNA testing, you’ll get a clear view of what your body actually needs - and what small changes can lead to big results.
Take a look at the range of DNA reports on offer:
Nutrient Core Report
This foundational assessment evaluates the impact of genetic variants on food tolerance and intolerance, appetite regulation, blood glucose balance, micronutrient requirements, detoxification capacity, and vulnerability to inflammation and infection.
Metals and Minerals Report
This foundational test analyses how gene variants can influence the absorption, distribution, and excretion of metals and minerals, affecting their balance and status in the body. While essential minerals are crucial for health when present in adequate amounts, excessive intake and accumulation can be harmful. Furthermore, environmental heavy metals can be toxic to humans and pose serious health risks.
Metabolics Report
Metabolism encompasses all cellular chemical reactions vital for life, including anabolism (building molecules like sugars and proteins) and catabolism (breaking them down to release energy as ATP). Maintaining a balance between these processes is crucial for healthy energy metabolism and cell function. The Metabolics Report offers insight into how genes shape metabolic differences and influence energy regulation, longevity, and healthspan.
Hormones Report
Steroid hormones are a group of hormones derived from cholesterol that act as chemical messengers in the body. They are involved in the regulation of many physiological processes in both men and women, such as the development and function of the reproductive system, metabolism, inflammation and the immune system.
Methylation Report
Methylation is the process of adding methyl groups, consisting of one carbon and three hydrogen atoms, to other molecules. It is involved in almost every metabolic process in the body, occurring billions of times every second in our cells and contributing to numerous crucial functions.
Histamine Intolerance Report
Histamine has many functions: as a neurotransmitter, communicating messages to and from the brain and nervous system; triggering the release of stomach acid to help digestion; and it can also be released after stress, injury or allergic reaction as part of the body’s immune response
Detoxification Report
Detoxification is the physiological removal of toxic substances from the human body. It is mainly carried out by the liver, and to a lesser extent, the small intestine, kidneys and lungs. Substances such as nutrients, food additives, pesticides, medications, air pollutants, alcohol and hormones are transformed from being fat-soluble to water-soluble, allowing them to be more easily excreted from the body. The process occurs in two major phases: Phase I primes toxic molecules for deactivation, and Phase II finishes the deactivation and prepares for elimination.
Nervous System Report
The nervous system supports the transmission of messages around the mind and body, enabling an individual to respond to their environment. A neurotransmitter is a molecule that carries signals between neurons and across nerve junctions (synapses). Excitatory neurotransmitters increase the likelihood that a neuron will fire a signal, while inhibitory neurotransmitters have the opposite effect. In order for us to interact effectively with our environment, these must remain in balance.
Thyroid Balance Report
The thyroid is an endocrine gland in the neck that produces two thyroid hormones - triiodothyronine (T3) and thyroxine (T4), and calcitonin. Thyroid hormones control the metabolism of almost every cell in the body, with wide-ranging metabolic, developmental and cardiovascular effects.
Athlete Report
DNA sequencing has opened the door to personalised approaches to health and fitness, enabling a more intelligent approach to training, recovery and performance. In this report, we present elements of your unique DNA profile that have been shown to affect athletic performance.
