The art of designing clinical trials with dietary supplements
According to the usual practice for pharmaceutical and nutritional studies there are comparable inter-national ethical and scientific quality standards, such as the guidelines set forth by the International Conference on Harmonization (ICH) Guidelines for Good Clinical Practice (GCP) and the Declaration of Helsinki regarding the design, conduct and record of a study. But apart from those, there is one special characteristic regarding nutritional trials. This distinction is at the same time the biggest chal-lenge while designing and conducting nutritional trials: food is not medication.
As opposed to drugs, the substances which are supplemented in nutritional trials occur in commer-cially available food and consequently are present in the human organism and its cells. They tend to act in a network together with a variety of different nutrients and affect multiple cells and organs. Therefore, the requirements caused by the complexity of nutritional trials can only be fulfilled by spe-cialized experts. Beyond that, the expected physiologic effects are small due to quantifying an add-on. Furthermore, the recommended intake is within the physiological range.
That is why the careful selection of relevant endpoints and an appropriate collective of healthy volun-teers or-in some cases-volunteers with an increased risk of a special disease is of particular im-portance. Additionally, accurately defined inclusion and exclusion criteria as well as highly standard-ized conditions during the conduction of the trial reduce environmental disturbance variables (e.g. age, gender, nutrition) to an unavoidable minimum.
To design a nutritional trial while viewing the problems of testing effects on health in its entirety is the key qualification of specialized experts.
Nutritional CRO & Study site: "Nutrition can be more"
We consider ourselves as a nutritional CRO with profound expertise and longstanding, international experience in nutrition-related questions involving bioactive ingredients. The interdisciplinary team offers valid strategies to cover customer needs. The precise implementation in our in-house testing centre enables the verification of concepts, the detection of health related effects and the scientific substantiation of health claims for market communication. In order to guarantee highest quality, our internal QM system based on ICH-GCP is established.
The aim of our studies is the verification of concepts, the detection of health-related effects to rein-force products and the scientific substantiation of health claims for market communication.
