Vitamin and mineral metabolism (e.g., vitamin D, folate, B vitamins)
Caffeine and alcohol metabolism
Fat and carbohydrate processing
Lactose/gluten-related traits (where included)
Weight management tendencies
Appetite and satiety pathways
Exercise–nutrition interactions

Nutrigenomix
Clinical-style personalized nutrition
One of the more nutrition-specific options; commonly used through health professionals. It focuses on diet-related genetic variants rather than ancestry.
Yes. What you’re looking for is usually marketed as a nutrigenomics or nutrigenetic DNA test. These tests analyze genetic variants associated with things such as nutrient metabolism, caffeine/alcohol metabolism, lactose tolerance, omega-3/fat metabolism, and sometimes weight or exercise response.
A few important distinctions:
Nutrigenetics: asks how your genetic variants may affect your response to particular foods or nutrients.
Nutrigenomics: broader field examining interactions between nutrition and genes.
General ancestry DNA tests: may contain useful genetic data, but aren't necessarily designed or interpreted specifically for nutrition.
The scientific evidence is still developing. The Academy of Nutrition and Dietetics concluded that evidence for incorporating genetic testing into nutrition care remains limited, and a systematic review found substantial variation in the scientific validity of individual gene–diet associations. PubMedPubMed MedlinePlus likewise cautions that the relationship between individual variants and complex traits such as weight or nutrition can be difficult to predict.

Yes. What you’re looking for is usually called a nutrigenomics or nutrigenetics test—a DNA test designed to look at how genetic variants may influence your response to nutrients, foods, caffeine, alcohol, exercise, or dietary patterns.
A few important distinctions:
Nutrigenetics: looks at specific genetic variants and how they may affect nutritional responses—for example, lactose digestion, caffeine metabolism, folate metabolism, or omega-3 response.
Nutrigenomics: broader field examining interactions between genes and diet.
A general ancestry/health DNA test may contain some relevant variants, but it isn't necessarily designed to provide a useful nutritional-genomics report.
What I'd look for in a good test
Rather than choosing based on the number of genes tested, I'd prioritize:
Clearly identified SNPs/genes and the scientific evidence behind each recommendation.
Recommendations covering things such as macronutrients, micronutrients, caffeine, lactose, alcohol, vitamin metabolism, and potentially lipid/glucose response.
Yes. What you’re looking for is generally called a nutrigenomics or nutrigenetic test. These tests analyze genetic variants associated with things such as nutrient metabolism, caffeine/alcohol metabolism, lactose tolerance, omega-3/fat metabolism, folate metabolism, weight/body composition, and exercise response.
Yes. What you’re looking for is usually called a nutrigenetic or nutrigenomics DNA test. These tests analyze genetic variants that may relate to things such as nutrient metabolism, caffeine response, lactose tolerance, omega-3/fat metabolism, folate metabolism, and weight-related traits.
There are a lot of commercial options, but I’d be selective. A 2026 review of the consumer market found 104 companies offering 204 nutrition-related genetic testing panels; only about half publicly disclosed which genes they tested, and the evidence supporting many of the resulting dietary recommendations remains limited.
What I'd look for
A good test should:
Focus primarily on nutrition, rather than being a general ancestry/health DNA test with a small nutrition add-on.
Offers nutrition reports covering areas such as nutrient processing, food response, and metabolism; available in Europe.
Inagene Diagnostics Nutrition & Fitness
Nutrition + exercise genetics
Reports on markers related to metabolism, food sensitivities, nutrient absorption, and exercise response.
Biron Genetics DNA Nutrition Test
Nutrition-focused health report
Includes areas such as vitamin D, caffeine, omega-3, sodium, and macronutrient-related traits, with dietitian support.
DNAfit
Diet + fitness genetics
Combines nutrition-related genetics with lifestyle recommendations.
A few things to check before buying:
Gene transparency
Prefer companies that disclose the genes/variants they test and explain the evidence behind recommendations. A recent review found large variation among direct-to-consumer nutrigenetic tests in the genes analyzed and the support provided.
Human interpretation
A report interpreted by a registered dietitian, nutritionist, or clinician can be more useful than a purely automated app, especially if recommendations involve supplements or major diet changes.
Expectations
These tests usually identify genetic tendencies, not your current nutrient status. For example, a gene result related to vitamin D metabolism does not tell you your actual vitamin D blood level; a blood test does.
Privacy
Read the DNA storage, deletion, and data-sharing policies before submitting a sample.
If you are in Portugal/Europe, I would particularly look at providers that operate under EU privacy rules (GDPR) and offer European processing options; ADNTRO is one example, and some clinics also offer nutrigenomic programs locally.
If you tell me your country, budget, and whether you want a raw DNA file you can reuse or just a nutrition report, I can narrow the options.
Nutritional genomics (often split into nutrigenomics , how diet affects gene expression, and nutrigenetics , how your genetic variations affect your response to nutrients) examines single-nucleotide polymorphisms (SNPs) related to metabolic pathways, vitamin absorption, and food tolerances.[1][2]
How Nutritional Genomics Tests Work
Most direct-to-consumer or clinician-guided nutrigenomic tests use a simple cheek swab or saliva sample to analyze specific genetic markers. Common areas evaluated include:[1][2]
Macronutrient Metabolism: How efficiently your body processes carbohydrates, fats, and proteins.
Vitamin and Mineral Response: Genetic variations (such as in the MTHFR or VDR genes) that may influence how you absorb, transport, or utilize specific micronutrients like folate, vitamin D, or B12.[1]
Food Sensitivities / Metformin-like responses: Markers associated with lactose tolerance, gluten processing, or bitter taste perception.
Behavioral Traits: Genetic markers tied to satiety, sugar cravings, and snacking tendencies.[1]
Clinical Context and Considerations
While these tests offer fascinating biological insights, major medical and dietetic organizations emphasize that genetics are only one piece of the puzzle.
Gene-Environment Interaction: Your actual phenotypic health and nutritional needs depend heavily on your baseline diet, gut microbiome, physical activity, and overall lifestyle—not just your DNA sequence.
Actionable vs. Speculative: Some genetic markers have strong clinical backing (e.g., lactose intolerance or classic celiac risk alleles), while others offer associations that are still actively being studied in clinical research.
Professional Guidance: Interpreting complex panels—especially those flagging altered detoxification, methylation, or heavy-metal processing pathways—is best done alongside a registered dietitian nutritionist (RDN) or a clinical physician who understands functional genomics. You can explore practitioner directories via the Academy of Nutrition and Dietetics to find professionals specializing in personalized nutrition.
Popular Options in the Market
Living DNA (Nutrition): Focuses heavily on how your body processes different foods and translates genetic variants into tailored meal suggestions.
InsideTracker: Combines targeted DNA insights with actual blood biomarker panels to bridge the gap between your genetic predispositions and your current physiological state.
3x4 Genetics / Clinical Nutrigenomic Panels: Frequently utilized by functional medicine practitioners and nutritionists to provide comprehensive, clinician-reviewed metabolic and nutritional reports.[2]
To help me narrow down the right direction for you, please let me know:
Are you looking for a direct-to-consumer kit you can do at home, or would you prefer a test that includes a clinical consultation with a dietitian?
Do you have a specific health goal in mind (such as athletic performance, weight management, or investigating a specific nutrient deficiency)?
If your goal is nutrition specifically, rather than ancestry or disease screening, I'd prioritize a test that:
Clearly lists the specific genes/variants it analyzes.
Explains the scientific evidence behind each nutrition recommendation.
Distinguishes well-established associations from preliminary research.
Provides the raw genetic data if possible.
Has clear laboratory quality/validation information. Analytical validity and clinical validity are separate questions, and a technically accurate DNA result doesn't necessarily mean the dietary recommendation has been clinically proven useful.
Ideally provides access to a registered dietitian or genetic counselor rather than simply generating a supplement/diet shopping list.
If you'd like, I can compare the currently available nutrigenomics DNA tests in the U.S., including what genes they test, price, raw-data access, privacy policies, and how evidence-based their recommendations are.
Clinical or scientific references for the recommendations.
The ability to download your raw genotype data.
Strong privacy policies concerning storage and secondary use of your DNA.
Ideally, access to a registered dietitian or other qualified professional who understands nutrigenomics.
One caveat: the science is promising but still developing. The Academy of Nutrition and Dietetics concluded that evidence for using genetic testing to improve nutrition outcomes remains limited, and a systematic review found insufficient evidence to establish that adding genetic testing to nutrition care improves outcomes.
So I'd treat a nutrigenomics test as additional information, not as a definitive prescription for what you should eat.
If you tell me your budget (e.g. <$100, $100–300, $300+) and whether you want U.S.-based testing, clinical-quality testing, or simply the most comprehensive consumer test, I can compare the best currently available options and tell you which I'd choose.

What I'd look for
If your goal is “tell me how my genetics should influence what I eat,” I'd prioritize a test that:
Is explicitly designed for nutritional genomics, rather than an ancestry test with nutrition added on.
Identifies the specific genes/variants tested rather than simply giving proprietary “nutrition scores.”
Provides references to the scientific evidence behind its recommendations.
Gives you access to a registered dietitian or other qualified professional to interpret the results.
Clearly explains genetic-data storage, deletion, and whether your DNA can be used for research or shared with third parties.
One important caveat: nutritional genomics is a developing field. The relationship between many individual genetic variants and complex outcomes such as weight, cardiovascular risk, or optimal diet is not strong enough to treat a consumer DNA report as a medical prescription. MedlinePlus specifically cautions that lifestyle/nutrition genetic results can be difficult to interpret, and the Academy of Nutrition and Dietetics has described practical nutrigenetic dietary guidance as an emerging area rather than established routine practice.
If you tell me what you want the test to help with (e.g., weight loss, vitamins/minerals, inflammation, cholesterol, athletic performance, food sensitivities, or general personalized nutrition), I can narrow this down to the 2–3 best tests and compare price, genes tested, sample type, and whether a dietitian interprets the results.
Nutritional genomics (often split into nutrigenetics —how your genetics affect your response to food, and nutrigenomics —how food affects your gene expression) has a dedicated market of specialized direct-to-consumer and practitioner-backed DNA tests.
Unlike ancestry companies or broad health screeners (like standard 23andMe), these platforms focus strictly on macro- and micronutrient metabolism, food sensitivities, vitamin needs, and fitness optimization.
Popular, specialized options on the market include:
Nutrigenomix: A prominent choice heavily backed by academic research and designed to be administered through healthcare practitioners, dietitians, or nutritionists. They offer specialized panels (such as plant-based, sport, and fertility nutrition) based on a simple cheek swab. You can explore their methodology on the Nutrigenomix Official Website.
InsideTracker: Highly regarded for blending DNA analysis with actual blood biomarker data. Rather than just looking at what your genes say you are predisposed to do, it tests your blood to see how your body is actually performing, giving you a deeply customized nutrition, supplement, and lifestyle plan. More details are available on the InsideTracker Website.
SelfDecode: A software-driven platform that processes your genetic raw data (or provides a kit) to look at thousands of genetic variants related to nutrition, inflammation, and gut health.

MyToolbox Genomics: A more budget-friendly and accessible saliva-based test focusing heavily on nutrition, weight management, and biological aging pathways related to diet. You can view their offerings on the MyToolbox Genomics Website.
To help narrow down which nutrigenomics test fits your needs, tell me:
Are you looking to work with a practitioner (like a dietitian) or do a direct-to-consumer kit at home?
Are you trying to solve a specific goal (e.g., athletic performance, plant-based optimization, general weight management, or managing a health condition)?
If you are looking for a dedicated nutritional genomics (nutrigenomics) test—rather than a generic ancestry or disease-risk test like 23andMe—several professional-grade and consumer-accessible platforms focus entirely on how your unique genetic variants interact with macronutrients, micronutrients, metabolism, and inflammation.[2][3]
Top-tier options specialized in nutritional genomics include:
Nutrigenomix : Widely considered a gold standard in clinical nutrigenomics. It is backed by robust scientific leadership and clinical trials. Rather than selling directly to consumers off a shelf, it is administered through authorized healthcare providers, dietitians, and nutritionists who can accurately interpret your genetic markers for vitamin sensitivities, macro-metabolism, and-cardiac health.
3X4 Genetics : Offers an advanced foundational health and nutrition test that maps how your body processes specific vitamins (like B12, folate, choline, and Vitamin D), manages inflammation, and metabolizes fats and carbohydrates. Their reports are structured to give clear, actionable lifestyle and food prescriptions rather than overwhelming raw data.
DNAfit : A more fitness- and diet-centric consumer test (via the DNAfit Store ) that analyzes how your body responds to low-fat vs. low-carbohydrate diets, alcohol sensitivity, lactose tolerance, and nutrient requirements.[1]
What to Look For in a Nutrigenomics Test
Actionable Markers vs. Disease Risk: High-quality nutritional tests focus on functional pathways (methylation, vitamin absorption, detoxification) rather than scaring you with probabilistic disease risks.[2]
Practitioner Support: Because interpreting single nucleotide polymorphisms (SNPs) like MTHFR or VDR can be complex, tests that partner with or require a registered dietitian or functional medicine practitioner usually yield the best real-world results.[1]
If you'd like to narrow this down, let me know:
Are you looking for a direct-to-consumer kit you can do completely at home, or do you want to work with a practitioner/dietitian to review the results?
Are you trying to solve a specific issue (e.g., chronic fatigue, weight management, optimizing athletic performance)?
Distinguish established findings from speculative ones.
Cover nutrient metabolism, macronutrient response, caffeine/alcohol metabolism, food sensitivities/tolerance, and cardiovascular/metabolic traits rather than simply producing a generic "eat this, not that" diet.
Provide interpretation by a registered dietitian, genetic counselor, or appropriately qualified clinician, rather than relying entirely on an algorithm.
Give you access to your raw genetic data if possible.
Have a clear policy for DNA storage, research use, deletion, and sharing.
One important caveat: nutrigenomics is promising, but it isn't yet at the point where a DNA test can reliably tell you the "perfect diet." The Academy of Nutrition and Dietetics has concluded that evidence for incorporating genetic testing into nutrition care remains weak, and randomized trials have generally not established strong clinical benefits.
If you want, I can compare the best currently available nutrigenomics DNA tests—including price, number/type of genes, nutrition areas covered, raw-data access, clinical/dietitian support, privacy, and scientific credibility—and narrow it down to 2–3 I'd actually consider.
When looking for a DNA test that focuses specifically on nutritional genomics (nutrigenomics)—the study of how your genetic makeup interacts with your diet—you will want to bypass broad ancestry-tracking kits and look for companies that analyze specific single nucleotide polymorphisms (SNPs) related to metabolism, vitamin absorption, and food sensitivities.
