Nutrigenomics Testing
Understand your genes. Personalise your nutrition. Support your health for life.
Nutrigenomics & Personalised Nutrition
We all respond differently to food. Our health history, lifestyle, environment, microbiome and personal preferences all play a part - and our genes may add another piece to the puzzle.
Nutrigenomics explores the relationships between genes, nutrition and the way the body processes or responds to certain nutrients and dietary factors.
As a trained nutrigenomics practitioner, I use this information carefully within a broader nutritional therapy assessment. Genetic information does not replace your health history, symptoms, blood tests or everyday experience, but it may provide additional context when creating a personalised plan.
Nutrigenomics helps you understand how your genetic variations may influence your needs, so you can make more personalised nutrition and lifestyle choices.
What is nutrigenetics?
Nutrigenetics looks at how small differences in your DNA may influence the way your body responds to food and nutrients.
These differences, known as genetic variants or SNPs, can affect processes such as nutrient absorption, enzyme activity, metabolism and hormone signalling. They do not determine your health or predict that a condition will develop, but they may highlight individual strengths, needs and areas that could benefit from additional support.
Your results are most useful when considered alongside your diet, symptoms, lifestyle, medications and environment.
What is the difference between nutrigenetics and nutrigenomics?
Nutrigenetics looks at how your genes may affect your response to food, nutrients and lifestyle.
Nutrigenomics looks at how food, nutrients and lifestyle may influence the way your genes and related biological pathways function.
In practice, the two work together: testing identifies relevant genetic variations, while nutrigenomics helps turn those insights into personalised nutrition and lifestyle recommendations. Your DNA cannot be changed, but factors such as diet, sleep, stress and physical activity can influence how your genetic tendencies affect your health.
What nutrigenomics can - and cannot - tell us
A nutrigenomics report may highlight genetic variations connected with certain biological pathways or nutrient-related processes.
However, genes do not determine your future, and a genetic variation does not automatically mean that you have—or will develop—a health problem.
Your genes interact with many other factors, including:
your usual diet
nutrient status
sleep and stress
physical activity
medications
environment
age and life stage
current and previous health concerns
For this reason, I never interpret a genetic result in isolation.
Lifecode Gx nutrigenomics reports
Each Lifecode Gx report explores genetic variations linked to a particular area of health. Your results reveal inherited tendencies rather than diagnosing a condition or measuring what is happening in your body today. I interpret them alongside your symptoms, diet, lifestyle and existing test results, then translate the findings into practical, personalised recommendations.
-
What it explores:
A broad overview of how your genes may influence your response to caffeine, lactose and gluten-related factors; your needs for key vitamins; appetite and blood sugar regulation; inflammation, glutathione, salt sensitivity, microbiome diversity and circadian rhythm.Why choose it:
A strong starting point if you want a wide-ranging picture of your nutritional needs or are unsure which area to investigate first. It can also highlight where a more specialised report may be useful. -
What it explores:
Genetic pathways involved in appetite regulation, nutrient sensing, blood sugar control, fat metabolism, cholesterol and bile, mitochondrial energy production and inflammation.Why choose it:
Particularly useful if you want to understand more about appetite, cravings, energy, weight management, blood sugar, cholesterol or your long-term metabolic health. The results can help identify which nutrition and lifestyle strategies may deserve greater priority for you. -
What it explores:
Genes involved in the production, regulation, transport, signalling and metabolism of steroid hormones, including oestrogen, progesterone, testosterone, DHEA and cortisol. It also considers hormone detoxification and the stress-response pathways.Why choose it:
Useful when exploring hormonal wellbeing, menstrual or menopausal changes, libido, stress response and hormone metabolism. It provides personalised context for nutrition and lifestyle support but does not measure your current hormone levels. -
What it explores:
Five interconnected pathways involved in folate metabolism, methionine, neurotransmitters, transsulphuration and the urea cycle. It also considers how your genes may affect the use of nutrients such as folate, vitamins B6 and B12, choline, betaine, zinc and magnesium.Why choose it:
Methylation supports many processes throughout the body, including energy production, neurotransmitter balance, hormone metabolism and detoxification. This report can help identify possible pathway bottlenecks and guide more appropriate nutritional support - rather than focusing on a single gene such as MTHFR. -
What it explores:
Genes and nutrients involved in breaking down histamine, including the DAO pathway in the digestive system and the HNMT pathway in the nervous system and lungs.Why choose it:
May be helpful when histamine sensitivity is suspected or when symptoms appear to be linked to certain foods, alcohol, stress or medication. It can identify which histamine-processing pathways may need support, although it cannot diagnose histamine intolerance by itself. -
What it explores:
Genetic variations involved in the body’s Phase I, Phase II and Phase III detoxification pathways, as well as glutathione production and protection from oxidative stress. These pathways help process hormones, alcohol, food additives, medications and environmental substances.Why choose it:
Useful if you want to understand your individual capacity to process and eliminate different compounds and identify nutritional support for these pathways. Results may also guide practical ways to reduce avoidable environmental exposures. Medication should never be changed on the basis of this report without medical advice. -
What it explores:
Genes involved in the production, signalling and breakdown of neurotransmitters such as serotonin, dopamine, noradrenaline, adrenaline, GABA, glutamate and melatonin, as well as the endocannabinoid system.Why choose it:
May provide useful insights when exploring stress resilience, sleep, motivation, concentration, mood and nervous-system balance. It can help personalise nutritional and lifestyle support but does not diagnose a mental-health or neurological condition. -
What it explores:
Genes involved throughout the thyroid-hormone lifecycle, including hormone production, activation, transport and metabolism. It also considers nutrient cofactors, inflammation and genetic susceptibility connected with thyroid autoimmunity.Why choose it:
Useful if you want to understand how your genetic profile may influence thyroid-related pathways and which nutrients or lifestyle factors deserve closer attention. It should be used alongside thyroid blood tests, symptoms and appropriate medical care - not as a replacement for them. -
What it explores:
How your genes may affect the absorption, transport, use and excretion of essential minerals such as iron, magnesium, calcium, copper, selenium and zinc, as well as the handling of heavy metals including mercury and arsenic.Why choose it:
May be valuable when mineral balance, supplementation or environmental exposure is a concern. It can identify areas that deserve closer dietary attention or targeted laboratory testing, but it does not measure your current mineral or heavy-metal levels. -
What it explores:
Genetic factors that may influence cardiovascular adaptation, exercise fuelling, muscle and connective-tissue characteristics, inflammation, oxidative stress, sleep, motivation, recovery and performance.Why choose it:
Useful for anyone who wants to make training more personal—not only competitive athletes. It can help inform choices around exercise type, fuelling, recovery and injury resilience while taking your current fitness and health into account.
Which report should I choose?
You do not need to order every report. We begin with your concerns, goals and existing health information, then select the report—or combination of reports—most likely to give you useful, actionable insights.
Nutrigenomics - small changes, big impact.
What happens to your genetic data when the report is done?
The lab disposes of your sample after 6 months. Within a 6-month period, any additional report can be added on at a reduced price as no test kit is required.
