Puoi verificare tu stesso la purezza

You do not have to take our word for it. Every product batch is independently tested before it becomes available. We publish the results, so you can check for yourself what is in the product and what it has been tested for.

What is tested?

Depending on the product, an independent laboratory checks:

01

Active ingredients

The identity and concentration of the ingredients tested.

02

Purity

The purity of the product.

03

Heavy metals

The presence of heavy metals.

04

Pesticide residues

Possible residues of pesticides.

That gives you insight into the composition and quality of the product you use.

Current test results per batch

Every certificate of analysis belongs to a specific product batch. It shows the batch number, the test date and the results, so you can match it to the product you received. Find the batch number on the back of the label.

From raw material to independent proof

We leave nothing to chance. These are the four steps we take to guarantee the highest level of purity.

01

Careful sourcing

We select raw materials on origin, purity, dose and absorption from strictly controlled producers, never on price alone. Our NMN comes exclusively from Lithuania at over 99% purity.

02

Dutch production

Formulation and encapsulation take place at CureSupport in the Netherlands, an FSSC 22000 certified facility audited by Kiwa and working to the European HACCP food safety guidelines.

03

Independent lab analysis

Every batch is analysed for purity and safety by Arotop Laboratorien in Mainz (part of Limbach Analytics), accredited to the ISO/IEC 17025 standard.

04

Published immediately

Once the results are approved, we publish the certificates directly and transparently on this page.

Purovitalis is an active member of Natural Health Products Netherlands (NPN), the trade association for trustworthy consumer information.

Transparency is part of quality

Science-based formulas and carefully chosen ingredients matter. But to us, quality also means that you can check the information. That is why we make the available test results public and show how our products have been assessed.
