Ever wondered why your friend can eat pizza every night and still fit into skinny jeans while you gain weight just looking at a slice… you’re not alone. While part of it is down to lifestyle, there is another powerful player in the mix: your genes. With the rise of nutrition and lifestyle DNA tests, you can get a peek into how your unique genetic blueprint influences the way your body responds to food and exercise.
What is the Randox Nutrition and Lifestyle DNA Test?
Your DNA holds the blueprint for everything from your hair colour—right down to how your body responds to food, exercise, and lifestyle choices.
The Randox Health Nutrition and Lifestyle DNA Test taps into that genetic information to unlock personalised insights to help you live smarter, eat better, and train more effectively.
Here’s a quick overview:
- Why: Understand how your genes influence nutrition, fitness, weight, and wellness.
- How: A simple, non-invasive saliva sample you can do at home.
- Insights: Discover your body’s unique tendencies—like how well you metabolise certain vitamins or handle caffeine.
- Personalisation: Use your results to tailor your diet, workouts and lifestyle habits.

Why does DNA matter for nutrition and lifestyle?
Most diets and workout plans are designed for the average person-but you’re not average. Some people gain weight more easily, others may be predisposed to low Vitamin B12 levels or lactose intolerance. Knowing this can be the difference between progress and frustration.
By looking at your DNA, this test reveals how your body uniquely responds to food and exercise.
The Randox test analyses key areas, including:
- Micronutrient Needs – Your genetic predisposition to deficiencies in vitamins like B12, D, C and A.
- Taste Preferences – Sweet Taste and Bitter Taste Perception
- Caffeine – How sensitive you are to caffeine.
- Weight & Metabolism – Genes related to obesity risk, hunger, fasting response, and appetite.
- Fitness and Exercise Response – Whether you’re better suited for endurance or strength-based training.
- Heart Health – Hypertension risk, high cholesterol and cardiovascular disease risk.
- Mental Health – Mental health related markers like HTR1B and NPAS2
- Sleep Patterns – Sleep traits

Supporting Key Health Concerns with DNA Insights
Recent Randox Health data reveals:
- Over 3 in 5 people having high LDL cholesterol
- Over 1 in 5 people have a possible Vitamin B12 deficiency
- 2 in 100 people have Coeliac disease
The DNA Test can help to provide insight into some of the genetic factors behind these trends:
- Heart Health Risks: Your genes can reveal whether you’re predisposed to high blood pressure or high cholesterol.
- Vitamin B12 Deficiency Risk: Testing of the TCN1 and MTHFR gene – both these genes are indictive of a vitamin b12 deficiency.
- Gluten Intolerance: Genetic testing of the following genes: HLA-DQ2.5, HLA-DQ8 will determine any intolerance to gluten.
By understanding these predispositions, you can take proactive steps—whether that’s adjusting your nutrition, supplementing wisely, or focusing on exercise.
