DNA metabolism tests

The starting point is the WeightLoss SLIM DNA test, with over 80 genetic variations, 24 analysis reports and around 140 pages.

It’s designed for anyone with a clear question: why is this harder for me than for other people? The analysis examines selected SNPs, or individual inherited sections of your DNA, which can reveal how your body processes food. The 24 analysis reports are divided into 5 chapters. They cover topics such as how you process carbohydrates and fats, how strong your sense of fullness is, and your vitamin and mineral requirements. The package includes the collection tube with funnel, the return envelope and access to the digital report. The WeightLoss SLIM DNA test does not include an assessment of over 1,000 foods; that’s only included with the three larger tests. If you’d like to take the next step as soon as you get your results, the DNA Metabolism Analysis builds on the same analysis and adds a plan and recipe book. You order online and collect the sample yourself at home. The lab then needs 15 to 25 working days (as of September 2026). What the test doesn’t do: it won’t tell you what to eat tomorrow, and it won’t create an energy deficit for you. It explains where your body makes things harder for you than for other people, and leaves it up to you to decide what to do with that information.

Depending on the test, you’ll get 24 to 74 analysis reports across 5 to 12 chapters, written for readers with no prior knowledge.

Each analysis report names the variant analyzed, explains what your result looks like for that variant, and describes what it means in everyday life. The chapters are organized by topic, not by gene, so you’ll read the section on feeling full rather than a list of letter abbreviations. The smallest of the five tests covers around 140 pages; the largest, 240. No one reads it in one evening, and no one needs to: the report is yours to keep, so you can look things up whenever a question comes up. What it doesn’t include is your energy expenditure today. That’s measured through your breath, usually by a sports medicine specialist, and it shifts with sleep and exercise. A genetic result obtained once remains useful indefinitely, so the report doesn’t include an expiration date. This point is important: a genetic variant describes a probability across population groups, not a determination of what’s true for you. How strongly a result ultimately affects you also depends on sleep and physical activity, and these are easier to change than your genes. That’s why each interpretation is accompanied by a recommendation based on your results, not a general rule. See the DNA weight-loss test category for an example of how this works for weight.

The NutriCare INFINITY DNA test analyzes 140 genetic variations, and its report has 8 chapters across around 200 pages.

It also includes an assessment of over 1,000 foods. So the report doesn’t stop at explaining how your body processes fats; it also tells you what that means for your shopping. It isn’t a list of forbidden foods. Each food is given an assessment based on your variants, and how you fit it into your weekly plan is up to you. The NutriCare INFINITY DNA test is designed for people who already think about their diet but still find themselves faced with conflicting recommendations. If your main goal is to lose weight, the WeightLoss SLIM DNA test already covers the key findings for that. The process is the same for all five tests: the kit arrives by mail, you collect saliva in the tube using the funnel, return it in the enclosed envelope, and receive your analysis within 15 to 25 business days of the sample’s arrival (as of September 2026). Your report is then available digitally. What the report can’t do is measure your current nutrient levels. It describes the needs suggested by your genetic makeup, which is not the same as a measured blood value. If you want to know both, combine the genetic analysis with a blood test.

Fewer than most people think. More important than the number of variants is whether someone explains what they mean.

When comparing tests, people look at the number first, even though it tells you the least. A table with lots of variants is no use if nobody puts them into context. Instead, look at the quality of the evidence: not every genetic association has been studied equally well, and a reliable report says so rather than making everything sound equally certain. And ask what happens after you get the results. A finding with no follow-up is just a file in your downloads folder. The second point is breadth. Five tests with different scopes doesn’t mean the biggest one is right for everyone. If you have one specific question, the smaller test will answer it just as well, without the chapters you’ll never read. If you still choose a broader test because you don’t want to commit to just one topic, the Longevity ALL IN ONE DNA test covers four topics in one report, with over 170 genetic variants, 74 analysis reports and 12 chapters across 240 pages: weight, nutrition, fitness and skin. The skin section covers skin type and skin aging, including the skin’s nutrient needs, so it’s about skincare choices, not skin diseases. It also includes an assessment of over 1,000 foods. Test once and get all four topics together, instead of buying four tests one after another.

That’s what the Fitness VITALITY DNA Test is designed for: over 100 genetic variations, 32 analysis reports, 6 chapters across 160 pages.

The Fitness VITALITY DNA Test tells you which training stimuli suit your genetic makeup and what it says about your muscle structure and recovery after exercise. It also includes an assessment of over 1,000 foods. Who can benefit: anyone who already follows a training plan and wants to know whether it suits them. If you’ve been doing the same workout for years and are frustrated by a lack of progress, the test can provide an objective indication of what you might adjust. It offers little to beginners, since almost any stimulus is rewarding during the first few months. The process is the same as for the other four: order online, provide a saliva sample at home, send it back, and receive your report 15 to 25 business days after the sample arrives (as of September 2026). The test does not replace performance diagnostics. It measures neither your endurance nor your pulse, and it cannot predict your race time. It describes the genetic makeup you’re training with. The report won’t prescribe a training plan either; it tells you what to consider for your next one and what your genetic makeup may indicate about recovery after a tough workout.

Nothing about your current vitamins, minerals, electrolytes, hormones, or gut flora. That requires a blood or stool sample.

None of the five tests tells you anything about diseases. None is an ancestry or paternity test. And none replaces a genetic test at a doctor’s office, which is done when a disease is a concern. These are two different things, and the distinction belongs in the text before you order. The tests here describe predispositions related to diet, training, and weight, nothing more. If you want to know how well-nourished you are today, you need a snapshot from your blood. That is a different type of test, using different sample material and with a shorter wait for results. These values fluctuate throughout the year, so they are measured repeatedly, whereas genetic results are obtained once and remain the same. Two people with the same variant can also live completely differently, and the result says nothing about which of them eats more healthily. Nor does it tell you whether your symptoms are caused by your diet. If something is affecting you for a while, you should see a doctor, and the report is then at most a way to prepare for the conversation. We provide the data, and the decision is yours. If you’d like to have your current nutrient levels measured, you’ll find the relevant blood tests under nutrient deficiency tests.
