Abstract
The (anti)oxidant status of individuals is an important factor for the risks of chronic diseases.
Biomarker measurements in serum/plasma is a good way to determine the status of the
oxidant/antioxidant balance. From our own experience, we come to a proposal of a set of biomarkers
for nutritional intake of antioxidants to determine the (anti)oxidant status in serum as a reflection of
nutrition. Serum concentrations of biomarkers of fat-soluble vitamins are not suitable to assess
transient changes in nutritional intake, because of their strong homeostasis. For long-term
epidemiological studies however, they are weil-suited. In addition, a number of oxidation/redox
biomarkers can be used in addition to the antioxidant to assess possible relations with health risks.
The best biomarkers for this purpose are the reactive oxygen metabolites and total thiols. Examples
will be given from large-scale European studies.
With the combination of vitamin A, vitamin E, carotenoids (as measured with HPLC), vitamin C,
reactive oxygen metabolites, biological antioxidant potency and total thiols (as measured with an auto
analyzer), an overall view is obtained concerning the intake and effect of antioxidants in nutrition and
aging research.
In this paper we describe the methods to measure a selection of these biomarkers in general
population. Critical points in biomarker validation with respect to blood sampling, storage conditions
and assay stability are discussed.
