Oxidative stress refers to the process by which the body is exposed to a level of free radicals which is higher than normal.
Free radicals are atoms or molecules which have free electrons and try to take electrons away from other atoms to stabilise their own chemically volatile state. A certain amount of free radicals is produced as part of normal metabolic processes and serves immunological functions. However, if this normal level is exceeded, there is a risk of cell damage – oxidative stress. This results in lipids (fats) and proteins being oxidised and mitochondrial DNA being damaged.
More recent tests indicate a connection between oxidative stress and certain illnesses. Especially with regard to neurodegenerative illness such as Alzheimer’s or Morbus Parkinson, but also diabetic neuropathy and arteriosclerosis, it is presumed that there is a connection.
Cells have systems to protect themselves from oxidative stress in the form of antioxidants. These antioxidants include glutathione, alpha-lipoic acid, coenzyme Q10, selenium and vitamins C and E. If the level of free radicals exceed the antioxidative capacity, oxidative stress results.
We offer the following tests:
- Oxidative stress (lipid peroxidation/free radicals)
- Antioxidative capacity
- 8-OH desoxyguanosin (DNA oxidation)
- Antioxidant status (vitamin C, vitamin E, selenium, zinc, Q10, betacarotin, SOD, glutatathione-peroxidase)
- Glutathione peroxidase
- Superoxide dismutase
- Glutathione metabolism
