Measurement of human redox biomarkers

Determination of the most important endogenous antioxidant in a drop of capillary blood

A drop of capillary blood is collected from the finger and the reduced form of glutathione (GSH), the most important endogenous antioxidant, is determined. The examination is carried out by the scientific staff of FoodOxys using a modern portable device for which it has received a patent. Then, based on the measurement, a personalized nutrition plan is created.

Basic evaluation of the endogenous redox state for the creation of a personalized nutrition plan

Blood sample is collected and 3 redox biomarkers are determined, indicative of the endogenous redox state. More specifically, the levels of GSH, the most important endogenous antioxidant, the levels of thiobarbituric acid-reactive substances (TBARS), a redox biomarker associated with oxidative damage to lipids, and the activity of catalase (CAT), a crucial antioxidant enzyme, are determined. Based on the measurements, a personalized nutrition plan is created. The blood sampling and the corresponding measurements are repeated one month after the nutritional intervention in order to evaluate its benefits for metabolic health.

Thorough evaluation of the endogenous redox state for the creation of a personalized nutrition plan

Blood sample is collected and 9 redox biomarkers are determined, indicative of the endogenous redox state. More specifically, this pack includes:

  • Determination of redox biomarkers that provide important information regarding the state of the endogenous antioxidant defense –GSH, total antioxidant capacity (TAC), reducing power (Reducing Power).
  • Determination of the activity of crucial antioxidant enzymes – catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD), glutathione reductase (GR), enzymatic mechanisms involved in the protection of the cells against free radicals. Their determination provides important information on the expression of antioxidant, anti-aging, and anti-inflammatory genes.
  • Determination of byproducts of oxidative damage – thiobarbituric acid-reactive substances (TBARS) and protein carbonyls, redox biomarkers that are associated with lipid peroxidation and protein carbonylation, respectively. The presence of their high levels in the human body indicates the induction of oxidative stress.

Based on the measurements, a personalized nutrition plan is created. The blood sampling and the corresponding measurements are repeated one month after the nutritional intervention in order to evaluate its benefits for metabolic health.
