The Fitness VITALITY DNA Test analyzes over 100 gene variations from a saliva sample, presented in 32 analysis reports across 6 chapters and 160 pages. It’s designed for anyone who trains according to a plan and wants to know which training stimuli suit their genetic makeup. Topics include strength, endurance and post-workout recovery, as well as an assessment of over 1,000 foods. The sample is saliva rather than blood, and you collect it yourself at home. Once the sample arrives, expect 15 to 25 business days in the lab (as of September 2026), since genetic analysis takes longer than a blood test. It’s just as important to know what it doesn’t do: it won’t make you faster or build muscle. You pay once, because submitting another saliva sample later won’t change the genetic results.

The DNA test shows how you are predisposed, and a result obtained once remains useful permanently. The blood test shows how well-nourished you are today. Recovery is when adaptation to training actually takes place, and how quickly that happens varies between two people following the same plan. Part of this is predisposition, such as muscle structure and recovery after training. Another part changes with sleep, stress, training volume, and nutrition. Your predisposition tells you where your body makes things easier or harder; the snapshot tells you what you can change this week. A predisposition is not a certainty. It describes what is observed in many people with the same variant, not what will happen to you. If you’re interested in predisposition beyond sports, the DNA Metabolism Tests category is a good place to continue.

The BalanceCheck Electrolyte & Mineral Test measures 15 elements from a capillary blood sample: the electrolytes calcium, potassium, magnesium, sodium, and phosphorus, six trace elements, and four heavy metals. It’s designed for people who sweat a lot and don’t want to keep guessing whether their mineral balance is right for them. The kit arrives by mail, and you collect a blood sample yourself from your fingertip; instructions and a return envelope are included. Once the sample reaches the lab, analysis takes 3 to 5 working days (as of September 2026). You can then access your results in the customer portal, with the lab’s reference range alongside each value and an explanation rather than just a bare list of numbers. If a value falls within that range, it initially means only that there’s no indication of a deviation in that area at the time the sample was taken. The number doesn’t tell you more than that. Interpreting a result in light of your medical history is something to discuss with a doctor, and a printout of the numbers is a better basis for that conversation than a guess.

If you sweat a lot and for long periods and want to know where your levels stand, rather than simply replenishing them across the board. Electrolytes are minerals that, as charged particles, play a role in transmitting signals in nerves and muscles, such as potassium, sodium, calcium and magnesium. How much you lose during exercise depends on the duration, the heat and how salty your sweat is. An hour in a cool gym is a different calculation from three hours of cycling in summer, which is why general recommendations rarely fit an individual training plan. Also, the body keeps calcium, potassium and sodium levels in the blood tightly regulated rather than simply letting them drop. Chloride is also technically an electrolyte and is not included in the test, so the electrolyte profile is not complete. The BalanceCheck Electrolytes & Minerals Test shows which elements are measured and how they are grouped.

The PerformanceCheck Amino Acid Test is an amino acid profile based on capillary blood. It’s right for you if you train hard, eat a plant-based diet, or consume little protein and want to know whether your supply is keeping up with your demands. It includes 22 values, including the nine essential amino acids, as well as glutamine, arginine, taurine, ornithine, and citrulline from the urea cycle. The process differs from the electrolyte test in one detail you shouldn’t overlook: you take the sample while fasting, or it will measure your breakfast. Everything else is included in the kit, from the lancet to the return envelope. Laboratory analysis takes 3 to 5 business days after the sample arrives (as of September 2026), and you receive the results as a report with reference ranges and an interpretation. Amino acids aren’t just a sports topic. They are used to make muscles, enzymes, messengers, and antibodies, which is why the test is also intended for people who don’t compete.

No. A test provides numbers and an interpretation, but not a training plan, and a lab result does not explain a symptom. An abnormal result does not automatically mean you have a disease. What the DNA test shows is a predisposition that is more or less common in certain populations, not a statement about what will happen to you. A normal blood magnesium level does not rule out a deficiency in the tissues, because blood and tissue do not show the same thing. Amino acid levels depend on your most recent meal. A blood test does not measure how much you lose through sweating; it shows where your blood levels were at the time the sample was taken. What remains is an objective starting point for basing your next decision on something verifiable. The 22 values measured by the amino acid test and the role each group plays in metabolism are described in more detail in the PerformanceCheck Amino Acid Test.
