Micronutrient analysis? Here, specifically: vitamin D & B12

Test your vitamins from home

Before you buy the next vitamin stash: measure vitamin D and B12 in the lab – plus 8 more blood values, €99, no practice visit.

No vein needle, no finger prick, no appointment. The 8 extra values are heart, metabolism and organs – not ferritin, zinc or magnesium.

Included & not included

What this test measures – and what it doesn't

Vitamin D and B12 plus eight values for heart, metabolism and organs. What is not in the test – ferritin, zinc, magnesium – is in the right-hand list.

Included

10 blood values from one sample

  • Vitamin D (25-OH) - nutrient value
  • Vitamin B12 - nutrient value
  • ApoB - heart & arteries
  • Triglycerides - blood lipids
  • hsCRP - inflammation
  • Fructosamine - metabolism / blood sugar
  • Uric Acid - metabolism
  • eGFR (Cystatin C) - kidney function
  • Gamma-GT - liver
  • Albumin - protein status
Not included

Markers this test does not measure

  • Ferritin (iron stores)
  • Zinc
  • Magnesium
  • Selenium
  • Folate (Vitamin B9)
  • Omega-3 index
  • Complete mineral and vitamin profile

Is CHIRAYOU a complete micronutrient analysis?

No. With Vitamin D and Vitamin B12, CHIRAYOU measures two of the most common nutrient gaps plus 8 more health values - but not a complete micronutrient, mineral or vitamin profile. If you specifically want to measure ferritin, zinc, magnesium, selenium, folate or omega-3, this test alone is not the right one.

Who it's for

Measure vitamin status – don’t guess.

A fit

For you if

  • You want vitamin D or B12 from the lab before you buy the next stash
  • You do not want a practice visit for that
  • Eight more values from the same sample are fine – heart, metabolism, organs
Not a fit

Not the right test if

  • You want a 30- to 50-marker micronutrient analysis
  • You want to measure iron, ferritin, zinc or magnesium
  • You expect a single drugstore-shelf self-test
Why this test

Before you buy the next vitamin stash

A bottle on the shelf does not tell you whether you need vitamin D or B12. This test measures both in the lab – plus eight values from the same sample.

Vitamin D + B12 in the lab

Both values are measured as 25-OH vitamin D and vitamin B12 at the Limbach lab – not guessed from the bottle.

No appointment, no finger prick

Tasso+ on the upper arm, return in the envelope. Typically 3–5 business days after you send the sample, the report is in the app.

Eight extra values included

The same sample also covers heart, metabolism and organs – not more vitamins, but the context around D and B12.

Same lab as a Praxis

Analyzed in a DAkkS-accredited lab. Physician-led.

The convenience does not come from a softer lab. It comes from cutting out the clinic visit - not the rigor behind the result.

Dr. med. Claudia Hennig, specialist in general medicine with an MSc in preventive medicine, is responsible for CHIRAYOU’s clinical protocol – markers, reference ranges and the lab partnership. Every value is placed against the analysing lab’s reference range and explained in plain language. If a value is clearly outside the range, your report says so and recommends talking to your doctor.
