Why take a DNA and blood test for sports and fitness?
If you are physically active or want to specifically build muscle, lose fat, or improve your endurance, it is essential to understand how your body works. A DNA and blood test for sports & fitness shows you how your metabolism functions, how quickly you recover, how your body responds to training, and which nutrients you really need.
With a fitness DNA test, you can find out, for example, whether you are genetically more responsive to strength or endurance training, how high your risk of injury is, how efficiently your muscles work, and how your body provides energy. An additional blood test provides information about vitamin D, iron, B12, magnesium, or inflammation levels—all factors that significantly affect your performance and recovery.
This means you no longer train “by feel,” but based on real body data that helps you optimize your training and make faster progress.

Causes of Performance Decline and Training Plateaus
Performance decline rarely occurs overnight. It is usually caused by a combination of nutrient deficiencies, hormonal imbalances, overtraining, stress, or an unbalanced diet. If you are not making progress despite training, tire more quickly, or are injured more often, deficiencies in magnesium, iron, vitamin D, or B vitamins, as well as thyroid or stress hormone levels, may play a key role.
Genetic factors also influence your ability to train: Some people are more prone to muscle fatigue, recover more slowly, or have lower VO2 max potential. Others build muscle more quickly or burn fat more efficiently.
A DNA and blood test shows you exactly which factors are limiting your performance—so you can take targeted action.
Understanding Your Body During Training: Energy, Recovery & Resilience
Athletic success is based on a finely tuned interplay of energy supply, recovery, muscle function, and mental resilience. When one of these areas becomes unbalanced, it directly affects your performance.
By analyzing your genetic predisposition, you can understand how efficiently your body breaks down lactate, how your muscle fiber types are distributed, and which dietary patterns best support your energy levels. At the same time, a blood test shows whether important markers such as vitamin D, iron, magnesium, omega-3, or inflammation markers are creating optimal conditions—or subtly holding you back.
This allows you to tailor your training, diet, supplementation, and recovery precisely to your body.
Optimize Your Training Results with a Blood Test—from the Comfort of Home
A blood test for sports and fitness not only shows whether you are lacking important nutrients—it also explains why your performance has plateaued or why you do not feel fit despite training. Vitamin D affects muscle strength, iron is crucial for oxygen transport, magnesium supports muscle function and recovery, while omega-3 and inflammation markers show how well your body responds to physical stress.
With a mybody® blood test, you can conveniently check all these values from home. The capillary blood sample is analyzed in a laboratory, and you receive an easy-to-understand report with clear recommendations: more energy, better recovery, fewer injuries, and more efficient training results.
That way, you train smarter—not harder.
What Are the Consequences of Nutrient or Performance Deficiencies for Athletes?
Nutrient deficiencies have a particularly strong impact on physically active people. They can lead to exhaustion, performance drops, increased susceptibility to injury, muscle weakness, poor recovery, and even hormonal imbalances.
Iron or B12 deficiency reduces your endurance and workload capacity, vitamin D deficiency weakens muscles and bones, and magnesium or potassium deficiencies cause muscle cramps and fatigue. Hormonal disturbances, such as an imbalanced TSH level or elevated stress hormones, can also lead to training plateaus or sleep problems.
If left untreated, these deficiencies prolong recovery times, weaken the immune system, and increase strain on muscles and joints—which can lead to overuse injuries and other injuries in the long term.
Why Does My Diet Affect My Performance and Recovery?
Your diet determines how much energy is available to your body, how quickly you recover, and how well your muscles adapt to training. Carbohydrates provide quick energy, proteins support muscle growth and repair, healthy fats regulate hormones, and micronutrients keep your metabolism and nervous system stable.
When certain vitamins or minerals are lacking, your body functions below its potential: You feel exhausted more often, your muscles recover more slowly, and you are able to benefit from fewer training stimuli. At the same time, dietary habits, gut flora, and genetic predisposition influence how well your body can absorb nutrients in the first place.
With an individualized analysis of DNA and blood values, you can identify which dietary strategy best supports your performance—for more energy, strength, and endurance.
Frequently Asked Questions
In this overview, you’ll find answers to common questions about the mybody tests.
What are DNA metabolism, blood, gut, and self-tests?
- DNA metabolism tests (saliva): show genetic tendencies related to fat/carbohydrate utilization, appetite regulation, and exercise tolerance – the basis for personalized nutrition and sports. Learn more. mybody®x
- Blood tests (capillary blood): check vitamins, minerals, hormones, and inflammation markers – ideal for prevention and monitoring. Blood tests. mybody®x
- Gut/microbiome tests (stool): analyze bacterial diversity and dysbiosis and provide nutritional recommendations for a stable gut flora. Microbiome tests. mybody®x
- Self-tests: tested home kits with laboratory analysis – simple, discreet, and without a doctor’s appointment. All self-tests. mybody®x
Are the mybody tests ISO-certified laboratory analyses?
Yes. mybody® repeatedly states that the analyses are carried out in ISO-certified laboratories and are recognized as medical self-tests. This ensures reproducibility, accuracy, and quality-assured processes—the basis for reliable results and clear recommendations. mybody®x+1
Are mybody products also available through a subscription?
A classic subscription with savings is currently not promoted as a standard option on the website. However, there are promotions/bundles as well as payment options such as installment payments or “buy now, pay later” that are communicated in several places.
