Free radicals / oxidative stress


What are free radicals?
Free radicals are produced in the human body by almost all metabolic processes that have to do with oxygen, and they are the main cause for the ageing processes in the human body. They are aggressive and have a negative effect on our cell metabolism, causing damage to our tissues and organs.

Free radicals
are oxygen-containing molecules that are lacking an electron. They therefore look for a suitable electron in the body's cells and steal it. This process is known as oxidation and results in an enormous amount of stress on the affected cell. For this reason, we also speak of oxidative stress. And then, the cell from which the electron was taken now seeks to steal a new electron itself, setting a chain reaction in motion. The more free radicals there are, the more chain reactions are triggered in the cells.

As the chemical weapon of the immune system, however, the free radicals also perform tasks that are vital to life. When there is inflammation, they form the defensive cells that can destroy the pathogens and that break down foreign substances. Normally, the body has enough defence mechanisms to counteract an excess of free radicals.

Free radicals and diseases

Free radicals enter our bodies through physical and chemical processes (e.g. plant protection products, UV radiation, electromagnetic radiation), diet (fats, preservatives, flavours, dyes), environmental pollutants (lead, cadmium, mercury, smog) or inhalation (e.g. cigarettes), alcohol, medicines and drugs. High-performance athletes have an increased risk as well. Since more oxygen is converted during sports, more oxygen radicals are created.
It is estimated that each of the approx. 70 billion cells in the body are attacked 10,000 times a day by free radicals. If the mechanisms remain in balance, nothing happens. With increased exposure to regular alcohol consumption, smoking, UV radiation, ozone, dust, stress, etc. the number of attacks is multiplied. When this happens, the excess free radicals begin to damage the body's cells or may even destroy the cells completely. Consequently, this can result in cell ageing, symptoms such as the formation of skin wrinkles and varicose veins, cardiovascular problems, dementia, poorer vision and joint complaints, and these can all help to bring about various diseases, such as arteriosclerosis, Alzheimer’s disease, rheumatism or cancer, diabetes mellitus, susceptibility to infections, skin disorders and depression.


Protection systems, called antioxidants, render these free radicals harmless. They voluntarily surrender an electron and transform into an antioxidant form so that the cells in the body are protected.
Our body produces enzymes with an antioxidative effect. Regular exercise, refraining from smoking, moderate alcohol consumption, protection from excessive UV radiation and a balanced diet (vegetables and salads, fruit, natural oils and fats), can all counteract an excess of free radicals.

Antioxidants include: vitamin C and vitamin E, trace elements such as iron, zinc, selenium and copper, beta-carotene, minerals and plant substances such as flavonoids.

Measured values of radicals

The determination of radical catchers and free radicals provides an indication of how balanced the human body is with respect to the harmful influences.
Moreover, determining the vitamins indicates whether there are enough antibodies against bacteria and viruses.

These laboratory tests help to identify an increased risk of disease in time.
