QUALITY STANDARDS
For safe products
Effective and safe products are no coincidence
Test parameters that go far beyond the minimum – every time. Our own laboratories specialising in humic acids analyse and standardise each batch of WH67® humic acids for numerous content and functionality parameters. This ensures consistent, documented quality – not just on paper but also noticeably in use.
Systematic raw material selection
Ensuring quality and functionality begins long before production with a targeted selection of raw materials and the subsequent composition of humic acids. Our experts analyse leonardites containing humic acid around the world and develop compositions that perfectly support the desired effects in animal nutrition.
Each batch is accompanied by a Certificate of Conformity (CoC) that confirms our humic acids meet the specified quality profiles.

60 years of experience – your advantage in every product
For over 60 years, we have been intensively involved in the research, analysis and utilisation of humic acids. As pioneers in this industry, we have developed not only special measuring techniques and analysis methods but also a deep understanding of which compositions work reliably and consistently.
This expertise flows into the WH67® humic acids – from the selection of raw materials to the release of the products. This guarantees effective, safe and scientifically proven humic acids that you can rely on.
The product HUMIGUT with natural WH67® humic acids supports the gut health of pigs, ruminants and poultry. It strengthens the intestinal barrier, promotes stable digestive function and contributes to normal faecal consistency. HUMIGUT therefore makes an important contribution to animal welfare, feed conversion and performance.
