What is your true biological age?
Your biological age reflects how fast your body is ageing on a cellular level, which may differ from your chronological age. These tests measure key ageing biomarkers to reveal your true rate of ageing and help you take steps to improve your long-term health. Learn more about what biological age means and how PhenoAge works. Already got your results? Read our practical guide to actionable steps to improve your biological age.
This Biological Age check reveals the age of your immune system and detects inflammation. Years of scientific research has helped develop a simple finger prick test that reveals how healthy you really are, empowering you to personalise your health through actionable points that leads to a better and healthier you.
NAD is a coenzyme found in all living cells. It plays a crucial role in cellular metabolism, especially in processes like energy production and DNA repair.
How well is your body methylating for long-term health?
Methylation plays a crucial role in detoxification, energy production, DNA repair and longevity. Poor methylation can accelerate ageing and increase risk of chronic disease. These tests give insights into your methylation pathways and epigenetic ageing. After completing your methylation test, read our follow-up guide: what to do next with your methylation results.
The Genetic Methylation Check analyses your DNA to provide insights into your individual methylation pathways. Methylation is the process which allows your genes to function optimally, so understanding your personal methylation pathways is key to optimising your health.
Follow-up to the Genetic Methylation Test: measures functional metabolic markers for detox, energy and nutrient processing.
As much as half of the population may have an MTHFR gene test mutation which can cause anxiety, insomnia, fatigue, depression and even autism. Find out more with this simple finger prick blood spot test.
As much as half of the population may have an MTHFR gene test mutation. MTHFR testing can provide valuable information about an individual's risk of health conditions associated with folate deficiency and elevated homocysteine levels.
What does your DNA say about your long-term health risks?
Your genes provide powerful insights into your predisposition for cardiovascular health, inflammation, metabolism, stress resilience and age-related disease. These DNA health tests help you understand your personal risk profile and optimise your health through personalised strategies.
The MyDNA Comprehensive Health Report is a personalised service that analyses your DNA to provide information about your genetic predisposition to various health conditions, as well as recommendations for diet, exercise, and lifestyle modifications that may help you optimise your health.
Combined DNA Comprehensive and Methylation tests covering 129 genes across metabolism, hormones, longevity and detoxification.
Is chronic inflammation accelerating your ageing?
Chronic low-grade inflammation — sometimes called “inflammaging” — is one of the primary drivers of accelerated biological ageing and long-term disease risk. Our cardiovascular and inflammation panels measure markers like hsCRP, homocysteine and lipid ratios to assess how inflammation may be impacting your healthspan. Read our deep dive into how inflammaging accelerates ageing.
Cytokines are small proteins that play a crucial role in the immune system and are involved in a wide range of physiological processes, including inflammation, cell growth and differentiation, and tissue repair.
Your body can't make omega 3 and omega 6 essential fatty acids and these must come from the food you eat. These essential fatty acids play a critical role in brain function, and immune and inflammation responses.
Test for oxidised LDL — an advanced lipid marker increasingly included in cardiovascular assessments.
How is your heart health tracking as you age?
Cardiovascular health is one of the strongest predictors of healthy ageing. These tests assess arterial health, lipid particle size, plaque risk and overall cardiovascular resilience — essential biomarkers for long-term health.
50% of people who develop cardiac disease have ‘normal’ cholesterol. A traditional LDL blood test doesn't measure small dense LDL particles, which can hide behind normal cholesterol and increase the risk of heart attack.
50% of people who develop cardiac disease have ‘normal’ cholesterol. A traditional LDL blood test doesn't measure small dense LDL particles, which can hide behind normal cholesterol and increase the risk of heart attack.
The most advanced strategy for coronary risk assessment is a ‘multi-marker’ approach which combines several risk factors, rather than only measuring the traditional markers of high blood pressure, cholesterol, smoking and diabetes.
Are your cellular energy levels declining with age?
Declining NAD+ levels and mitochondrial dysfunction play a major role in fatigue, inflammation and accelerated ageing. These tests assess your cellular energy status and metabolic resilience.
NAD is a coenzyme found in all living cells. It plays a crucial role in cellular metabolism, especially in processes like energy production and DNA repair.
Urine test measuring organic acid markers relevant to nutrient, gut and metabolic health.
Glutathione is an essential antioxidant involved in protecting cells from oxidative damage, supporting detoxification processes, and contributing to immune system function.
Feeling tired, foggy or off despite “normal” blood work? The Organic Acids Test uncovers hidden nutrient, gut, and metabolic imbalances that could explain your symptoms.
