Persistent fatigue can have many causes—from nutrient deficiencies to hormonal imbalances. With the Fatigue Check, you get a clear overview of relevant blood values, conveniently collected at home and professionally analyzed in the lab.
Du entnimmst eine Kapillarblutprobe im kleinen Röhrchen; die Analyse erfolgt im akkreditierten Labor. Dein Ergebnis steht sicher und digital mit verständlichen Referenzbereichen bereit.
Für wen ist der Test geeignet?
Für alle, die die Ursachen von Müdigkeit besser verstehen möchten – z. B. bei Erschöpfung, Konzentrationsproblemen, geschwächtem Immunsystem oder anhaltendem Stress.
Save 20 % on every delivery, pick your interval (every 3, 6 or 12 months) and pause or cancel anytime. Keep track of your values without reordering each time.
Everything for sampling: collection material, instructions, a return envelope for the lab and your personal test ID for the DoctorBox app.
Home tests do not replace medical advice. If your values are abnormal or you have symptoms, please consult a doctor.
Many people have undetected low values
Vitamin D is mainly produced in the skin by UV-B light and acts as a hormone on bones, muscles and the immune system. The storage form 25-OH vitamin D is measured.
In the winter months, with little time outdoors, darker skin, older age, excess weight or osteoporosis risk. According to the RKI, around 30 % of adults in Germany are not sufficiently supplied.
A deficiency often goes unnoticed. Fatigue, muscle weakness, bone pain, low mood and frequent infections are possible.

Below 30 nmol/l (12 ng/ml) is deficient, 30 to 50 nmol/l insufficient, 50 nmol/l (20 ng/ml) or more sufficient for bone health (RKI/IOM). Very high values from overdosing are harmful.
With a deficiency, agree the dose with a doctor (often 800 to 2000 IU daily) and re-check after 8 to 12 weeks. Summer sun on face and arms adds to the supply.
