Vitamins are essential for energy, metabolism, nerve function, and the immune system. With the Comprehensive Vitamin Check, you get a targeted overview of key vitamins—easily from home and professionally analyzed in a lab.
A capillary blood sample in a tube is all it takes to determine your most important vitamin levels. You’ll receive your results securely, digitally, and with clear reference ranges.
Für wen ist der Test geeignet?
Für alle, die ihre Vitaminversorgung überprüfen möchten – z. B. bei anhaltender Müdigkeit, Stress, Konzentrationsschwäche, Infektanfälligkeit oder im Rahmen der Vorsorge.
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 B1 (thiamine) is central to carbohydrate metabolism and the function of nerves and heart.
With high alcohol use, a very one-sided or strongly calorie-reduced diet, after bariatric surgery, on dialysis or with persistent vomiting.
Deficiency: fatigue, irritability, tingling and weakness in the legs, palpitations; severe forms affect heart and brain.

The body stores little thiamine, so a deficiency develops within weeks of insufficient intake. It is rare with a balanced diet.
Whole grains, legumes, pork and nuts provide thiamine. Supplement specifically with risk factors or a deficiency.
