An unirradiated and g-irradiated nutritive supplement named ExtraVit M was studied by electron paramagnetic resonance (EPR)spectroscopy in order to detect stable paramagnetic species following improvement of hygienic quality by g-radiation. Free radicals were induced by g-radiation in the studied samples from low absorbed doses, showing a certain sensibility of these samples to the radiation treatment. The EPR spectrum of irradiated ExtraVit M is typical for drugs or nutritive supplements containing high levels of sugars, vitamin C and cellulose.
