Dietary and nutritional supplement testing

Nutritional and dietary supplements marketed in tablet or capsule form can lie in the grey area between foods and medicines, particularly when marketed outside the EU. In addition to the standard food tests listed above, Donnington Laboratories are happy to apply the testing methods described in the British and European Pharmacopoeias to these products. These techniques also appear in our CLAS scope.
