What Does “3rd Party Tested” Mean?
“3rd Party Tested” means that our products are not only tested internally, but also verified by external, independent experts.
These laboratories have no affiliation with Heiltropfen, ensuring unbiased results and full consumer confidence.
Why It Matters
Independent testing ensures that what you see on the label is exactly what you get — nothing more, nothing less.
This commitment to transparency builds the foundation of trust between us and our customers.
What Every Test Verifies
- Purity: Free from heavy metals (As, Pb, Cd, Hg, Al, Ni), pesticides, and other contaminants.
- Potency: Active ingredients meet or exceed the declared label values.
- Safety: Tested for microbiological purity and heavy metals content, fully compliant with strict EU regulations.
Certified Laboratories
All analyses are performed by laboratories accredited according to ISO/IEC 17025, the international standard for analytical competence.
This guarantees that every test result is accurate, traceable, and reliable.
Our Commitment to Quality
We believe that natural supplements should be pure, effective, and safe.
That’s why we go beyond standard manufacturing requirements by investing in 3rd-party testing for every product batch.
Our customers deserve complete peace of mind when choosing Heiltropfen.
