Genetic & DNA Testing (UK-Wide)
Personalised insights into your health, hormones, and long-term risks.
Discover how your DNA influences your risk of fatigue, hormonal imbalances, anxiety, fertility issues, inflammation, and more. I offer UK-wide genotype testing via a simple cheek swab — no needles required — with analysis of over 150 of the most relevant genetic markers impacted by diet and lifestyle.
This test gives valuable insight into how your body functions and how to support it with personalised nutrition, supplements, and lifestyle changes.
What Can Genotype Testing Reveal?
-
Methylation & Detoxification
Understand how well your body processes toxins and supports biochemical balance. Poor methylation is linked to fatigue, brain fog, allergies, and hormonal issues.
-
Oestrogen & Androgen Balance
Explore risks for conditions such as PCOS, acne, endometriosis, blood clots, cardiovascular disease, mood swings, and hormone-driven weight gain.
-
Histamine Intolerance
Learn whether your genes affect histamine breakdown — this may contribute to migraines, allergies, insomnia, and anxiety.
-
Neurotransmitter Function
Assess how your brain communicates — imbalances may affect focus, mood, addiction risk, memory, and stress regulation.
-
APOE & Alzheimer’s Risk
Understand your genetic risk factors for cognitive decline and dementia, including analysis of APOE alleles and Bredesen protocol markers.

Oestrogen Balance
Oestrogen and androgen imbalances can contribute to sub-fertility, PCOS, endometriosis, menstrual irregularities, excess facial hair (women) or breast tissue (men), osteoporosis, cardiovascular disease, blood clots, acne, sexual dysfunction, mood swings, poor memory, weight gain and hormone-sensitive cancers.
Histamine Intolerance
Histamine intolerance is a toxic response by the body resulting from an imbalance between accumulated histamine and the capacity to break it down. Symptoms of histamine toxicity may mimic an allergic reaction including skin irritation, gastrointestinal upset, respiratory distress, headaches, insomnia and anxiety.
Nervous System
Neurotransmitters are chemicals that enable communication within and between neurons in the mind and body. Symptoms of neurotransmitter imbalance can include mood imbalances, depression, mania, attention deficit and obsessive-compulsive disorders, addictive behaviours, motor control disruption, anger, aggression and restlessness.
APOE Plus
The APOE4 genotype is a well-known risk factor for late-onset Alzheimer’s disease and cardiovascular diseases. This test also analyses genes involved in the three subtypes of Alzheimer’s - i) inflammatory, ii) toxic and ii) atrophic - described in the BredesenTMprotocol. Understanding your risk enables a personalised approach to managing it.

Methylation
Methylation is critical to keeping your body and brain biochemistry in balance. Common genetic variants (SNPs) can impact methylation and increase susceptibility to systemic imbalances and chronic health conditions such as cv disease, sub-fertility, mood swings, depression, dementia, fatigue, autoimmune disease, allergies and premature ageing.
Detoxification
Genetic variants (SNPs) can impact phase 1, 2 and 3 detoxification pathways and contribute to symptoms such as headaches, muscle aches, fatigue, allergies, skin disorders, weight gain, bloating, acid reflux and heartburn, excessive sweating, chronic infections, sub-fertility, decreased libido, poor mental function and lower stress tolerance.
