Vitamin D TEST and Adjustment


Categories: ,


If you don´t know your Vitamin D level, I strongly suggest you get it measured as soon as possible!

The total value of this Vitamin D – TEST is 105,10 Euros. Your price is only 80 Euros.


The Vitamin D TEST and Adjustment includes:

  • An individualised document for getting your blood sampling done
  • Measurement of your Vitamin D blood value (Calcidiol -25-OH-D)
  • A 30-minute appointment for the revision of your lab analyses in my therapy room
  • Your lab results, via email and printed
  • Information for the individual adjustment of Vitamin D target value
  • A suggestion which Vitamin D3 containing supplements to take



Upon ordering the Vitamin D TEST, you will get an individualised document to get you a blood sampling in the closest place to your home. This is usually done in Barbate, Chiclana, or Cádiz. Your lab results are usually ready 48 hours after blood sampling.

When the lab results are ready, we will meet together in my therapy room for a 30-minute appointment to revise your Vitamin D level. During our appointment, you will get a copy of your Vitamin D lab analysis. Furthermore, I will advice you how much Vitamin D3 you will need to take to reach your individual target value in the range of 40-60 ng/ml 25-OH Vitamin D.

After our appointment, I will send you a copy of your lab analyses and – if necessary – further information on how to supplement Vitamin D3 to reach your individual target value.


Why to do the Vitamin D – CHECK UP and Adjustment?

The reason why you should get your Vitamin D level checked, is that more than 75% of the people have a lack of vitamin D. International experts in the field recommend a target Vitamin D level of 40-60 ng/ml 25-OH Vitamin D (Calcidiol)1, 2.

Vitamin D is important for your bones, your calcium metabolism, and protects you against cancer. Studies3-12 have consistently shown, that a minimal Vitamin D blood value of 40 ng/ml is required to make sure you actually lower your overall cancer risk significantly.
