Clinical studies

Our experts provide a proper study design, based on scientific rationale and valid endpoints, to get the best chances of success.

Our clinical studies are performed according to GCP Guidelines including medical writing/reporting, ethical approval, conduction, data management, statistics and monitoring, taking into account the regulatory background of foods.

Our in-house study site and test laboratory guarantee efficient recruiting strategies and can perform critical biomarker analyses.

In vitro test-systems

For the detection of biological properties of bioactive ingredients, we use cell-based as well as cell-free models. We propose standard or complex and problem oriented in vitro test methods using single cell-cultures, co-cultures and organotypic models.  

Bio-Assays as well as bioavailability, biocompatibility and safety tests meet the required standards (THMP, …).
The evaluation of mode of action includes e.g. anti-inflammatory, anti-ageing and anti-oxidative properties, energy-metabolism.


As an accredited laboratory according to DIN ISO/IEC 17025:2018 we are your partner for quality assurance, product development and outsourcing using standard or tailor-made analytical methods.

Our analytical services are based on HPLC/UV-Vis/DAD/Fluor, photometry and UPLC/MS/MS techniques.

We analyse bioactive ingredients (e.g. vitamins, secondary plant compounds, antioxidants, botanicals) in various matrices as well as clinical samples.
