Nutrigenomics
Also called nutrigenomics tests. At GeneMatrix, GeneCore reads the genetic traits studied in diet, fitness and health, and sets them side by side in one plain report. Or choose one area on its own.

What it is
A DNA nutrition test reads small differences in your genes that research has linked with how people tend to handle food and drink: starches and sugars, fats, caffeine and milk sugar among them. It tells you which versions you carry and what studies have linked them with.
It is also called a nutrigenomics test. Nutrigenomics is the study of how genes and diet interact, and it works with groups of people: a trait shows a pattern across many people, not a verdict about one.
Some people call it a nutrition genetic test. Many cover more than food, and ours also read traits studied in exercise and everyday health, which is why the tests on this page cover diet, fitness and health.

How does it work?
You collect a sample at home with a gentle swab along your gums and post it back. The lab genotypes it, which means reading a set list of known positions in your DNA rather than your whole genome, and your report sets out each trait in plain words.
For general wellness and information, not diagnosis.
What it can describe
Traits in four broad areas. Each result names the trait, the version you carry, and what research has linked it with. The exact traits differ from test to test, and each test’s page lists its own.
- Food and drink
How you handle what you eat
Traits studied in starches and sugars, fats and protein, hunger and fullness, sweet and bitter taste, caffeine and milk sugar. - Exercise
How you respond to training
Traits studied in power and endurance, energy use during exercise, how people recover after hard sessions, and tendon and ligament injury. - Everyday health
How your body uses some vitamins
Traits studied in folate processing, in the levels of vitamins B12 and D, in a few other nutrients, and in the antioxidant enzymes the body makes. - Stress and sleep
Your body clock and stress response
Traits studied in whether people lean toward mornings or evenings, how caffeine affects sleep, and how the stress-hormone system responds to pressure.
For general wellness and information, not diagnosis.
Before you choose
How good is the evidence?
It varies from trait to trait. A few are well understood, such as the lactose trait. Many others come from studies of large groups that found small effects, which may not hold for any one person. Read each result as a likelihood, not a fact about you.
What does a result look like?
Each trait gets a short entry: its name, the version you carry, and what research has linked it with, in plain words. Nothing in it tells you what to do.
Is it a food intolerance test?
No. An allergy test looks at how your immune system reacts to a food now. A DNA nutrition test reads traits you were born with: the lactose trait describes a variant linked to digesting milk sugar, not whether milk upsets you today.
Is it the same as a medical DNA test?
No. A medical genetic test answers a clinical question, such as how you are likely to process a medicine, and a clinician may act on the result. A DNA nutrition test describes wellness traits for general information, and nothing in it is meant for a medical decision.

Its limits
What diet trials found about genes and weight
Our nutrition, supplement, athletic and wellbeing reports are for general wellness and information. The evidence behind these associations is less established than for our clinical panels, and these reports are not intended to diagnose, treat, cure or prevent any disease.
- It can’t choose a diet or a training plan for you, and it doesn’t tell you which supplements to take.
- It can’t predict your weight or promise any change in it. In trials, diets matched to genes did no better than diets that weren’t.
- It describes traits you were born with. It says nothing about what you eat now, and it doesn’t measure any level in your blood.
- Each trait is a pattern found across groups of people. Some are well studied and others less so, and your habits, surroundings and health matter as much as your genes.
- It isn’t a medical test, and it can’t diagnose, treat or rule out any condition.
Your traits
Something to read beside what you already know. Not a plan to follow.
Who it suits
Who is it for?
People who are curious about their traits and want something concrete to talk through with a dietitian, coach or clinician. It suits curiosity about a trait, such as how caffeine is linked with sleep, better than "what should I eat to feel better?", which needs a person who knows you. It is less useful if you want a diagnosis, a meal plan or a quick answer, or if a health condition shapes what you can eat; then start with your clinician.
What do you do with the results?
Read them as background, not instructions. Bring the report to a dietitian, coach or clinician and use it alongside what they know about you, your health and your habits. Your genes don’t change, so the report stays true; what you do with it can change as your life does. A dietitian or coach can help you judge which results are worth acting on and which to set aside.
The tests
GeneCore if you want the whole picture in one report; a single test if one area is all you want to know about.
