The blood test is perfect for you if you …
Regular strength or endurance training
– High exertion increases the need for essential amino acids.
Vegetarian or vegan diet
– Plant-based protein sources provide essential amino acids in different proportions.
Recovery that takes longer than it used to
– Glutamine and BCAAs are the first to become depleted during prolonged exertion.
Little protein in your daily diet
– Those who eat irregularly often fail to meet their needs without realizing it.
Persistent fatigue without an apparent cause
– Amino acids are building blocks for enzymes and signaling molecules.
You take protein powder without knowing your baseline level
– Without testing, it remains unclear whether it makes any difference at all.
Product description amino acid test
The mybody®x PerformanceCheck is an at-home blood test that measures 22 markers of amino acid metabolism, including all nine essential amino acids that your body cannot produce itself. Sample collection takes just a few minutes, and the analysis is performed by a specialist laboratory in Germany.
Amino acids are not just relevant to athletes. They are used to build muscles, enzymes, messenger substances, and antibodies. Those who train a lot have a higher need. The same applies to people who follow a plant-based diet, eat little protein, or have felt exhausted for a prolonged period. The amino acid test shows you whether your intake suits your everyday life.
The PerformanceCheck does not tell you how much protein you should eat, and it will not make any muscle bigger. Amino acid levels also fluctuate significantly depending on your last meal. Follow the fasting instructions in the guide; otherwise, you will be measuring your breakfast. Our consultation service is available if you have questions about your results.

What to expect:
The building blocks your body uses to build everything
Amino acids are not just a topic for athletes. They are used to build muscles, enzymes, signaling molecules, and antibodies. People who train a lot have a higher need – as do those who eat a plant-based diet, consume little protein, or have been exhausted for a longer period. The PerformanceCheck measures 22 values from this metabolism.
✔️ All nine essential amino acids – which your body cannot produce on its own. These include the three BCAAs leucine, isoleucine, and valine.
✔️ Glutamine, arginine, and taurine – values that become depleted first during intense exertion.
✔️ Ornithine and citrulline – two values from the urea cycle, through which your body breaks down nitrogen.
What the amino acid test cannot do: It does not tell you how much protein you should eat, and it will not make a muscle bigger. Amino acid levels also fluctuate significantly depending on your most recent meal – follow the fasting instructions in the guide, otherwise you will be measuring your breakfast.
The PerformanceCheck provides you with 22 figures and the corresponding interpretation – so you can adjust your protein intake to your goal, whether in training or everyday life.

Stefanie B. - 42 years old
I’m maintaining my weight
I wanted to lower the dosage of my thyroid medication, eat more healthily, and lose weight. I also wanted to prepare for the future and prevent illnesses.
Overall, I feel healthier. I was able to reduce my thyroid medication, I’ve lost weight, my body is more defined and my arms are firmer, my skin is much better, and my hair is shinier. I’m maintaining my weight.

Christian R. - 46 years old
My well-being has improved
I follow my food traffic-light plan and take a five-hour break between meals. I also regularly look for quick, simple recipes that suit my metabolic type.
Thanks to changing my diet, my food intolerances and therefore the symptoms have virtually disappeared—by 95%. A fantastic success for me! I have also lost a few extra pounds, which is a great side effect.

Vanessa W. - 24 years old
I lost 17 kg
Enjoyment and a vibrant, slim body—these were things I thought I couldn’t reconcile as a hobby cook. Until I tried the mybody® DNA metabolism analysis. Along the way, my waist circumference melted away.
I feel fitter than ever, and the best part is: no calorie counting—just eating delicious, satisfying food and enjoying pure joie de vivre thanks to the foods that suit my metabolism.
⭐️⭐️⭐️⭐️⭐️
Marissa H. - 28 years old
My skin has never looked so beautiful
After years of skin problems and unsuccessful treatments, I took the metabolic analysis—it was the turning point. After just one week of metabolism-optimized nutrition, my skin became clearer; after the gut cleanse, it was radiant and smooth. I also lost 5 kg, feel full of energy, and no longer have cravings.
This transformation was incredible, and I want to encourage others to try it too. That’s why I support the brand’s mission on Instagram

Your Fitness | Lifestyle Check: Get to know your body better and improve your health in a targeted way
An unbalanced metabolism or inadequate nutrient intake can place considerable strain on your body—and often manifests as fatigue, declining performance, or muscle discomfort. The difference between short-term exhaustion and genuine health imbalances often lies in the internal values that you can make visible with the Fitness | LifestyleCheck.
For example, a vitamin B12 or vitamin D deficiency may not become apparent immediately, but only over the course of several weeks through muscle weakness, concentration problems, or mood swings. Elevated creatine kinase levels can also indicate muscle overuse—especially if you are physically active. Cholesterol levels (HDL, LDL) likewise provide clues about the strain on your cardiovascular system. All these markers can be identified with a simple at-home blood analysis—quickly and conveniently.
Targeted analysis of your results provides well-founded recommendations on how to optimize your diet, training, and lifestyle. This allows you to recognize in good time where your body needs support—before minor weaknesses develop into major problems.

A balanced diet and targeted training can significantly improve your levels. Find out in good time whether you’re on the right track or should make changes.
