| Finally, a method for determining the redox status in blood after UV stress induction for electron spin resonance (ESR) spectroscopy is to be developed, which can determine the redox status in blood and assess the supply of antioxidants.

| The in vivo study aims to show that increasing the dose of vitamin C in physiological concentrations leads to antioxidant protection that can be quantitatively/qualitatively demonstrated in the blood. However, if the critical vitamin C concentration is exceeded, there can be an increased formation of free radicals (prooxidative effect) in the blood. | — |
