What are free radicals?Free radical
- is an atom or group of atoms that contain at least one unpaired electron.And if an unpaired electron, another atom or molecule is easily attached to it.There is a chemical reaction that can bring great harm to the body.
Free radicals are normally present in the body in small amounts, and a healthy body controls them.Some of the free radicals produced by the immune system.They destroy viruses and bacteria.Other free radicals are involved in the production of important hormones and activating enzymes necessary for life.Free radicals are needed by the body to produce energy and various substances, it needs.
sets of free radicals stimulates the formation of an even greater number of them, and this leads to an even greater damage to the body.As a result of the presence of dangerous free radicals can change the way cells encode genetic information, disrupt the structure of proteins.The immune system recognizes these proteins as foreign and try to destroy them.Ultimately, the mutated proteins spoil the immune system that lead to leukemia and other types of cancer, to heart and other diseases.
Free radicals can destroy the protective cell membranes, can lead to accumulation of fluid in the body that contributes to the rapid aging of the organism.Furthermore, this violates the calcium level in the body, which also leads to various diseases.
rise to free radicals cause various factors, namely: radiation exposure, prolonged exposure of the sun, polluting substances - tobacco smoke and car exhaust fumes, diet rich in fat.
shredders free radicals
Typically, the amount of free radicals is controlled by the action of free radical scavengers produced in the body naturally.These scavengers called antioxidants neutralize free radicals by linking them free electrons.As antioxidants are: enzymes that continually synthesized by the body;some vitamins and trace elements (A, C, E, beta-carotene, selenium);hormone melatonin;some herbs (bilberry, ginkgo biloba, grape seed extract, green tea).Many antioxidants can be obtained from food, such as eating sprouted grains, fresh fruits and vegetables.However, today, when the environment is very dirty, it is not enough.Therefore, a receiving additional antioxidants that minimize the effects of free radicals.
Alpha Lipoic Acid
Alpha-lipoic acid helps neutralize the effects of free radicals, increasing the antioxidant properties of vitamins C and E and glutathione.Moreover, it ensures the functioning of two key enzymes that convert food into energy.
Vitamin A and beta-carotene
Vitamin A and its precursor beta-carotene - a powerful free radical fighters.Vitamin A is essential for healthy skin and mucous membranes.It enhances the immune response.Beta-carotene and vitamin A destroy carcinogens that cause cancer, prevent heart disease and stroke, lower cholesterol.
Vitamin C as a very powerful antioxidant protects other antioksidatny, in particular, vitamin E, as well as brain and spinal cord cells.In addition, vitamin C neutralizes many harmful substances and plays a key role in the immune system.It increases the synthesis of interferon - a natural fighter against viruses and stimulates the activity of certain immune cells
Vitamin E - a powerful antioxidant, preventing the oxidation of lipids (fats).Since the cells consist of lipid membranes, it prevents their destruction by free radicals.Vitamin E improves oxygen uptake, enhances the immune response, plays an important role in the prevention of cataracts caused by free radicals, reduces the risk of coronary diseases.
to maintain normal levels of vitamin E is needed zinc.Selenium improves the absorption of vitamin E, so it is recommended to use together.
Glutathione Glutathione - a protein produced by the liver from amino acids.It is a strong antioxidant.It reduces the harmful effect of smoking, exposure to radiation, cancer chemotherapy, and toxins such as alcohol.As the catalyst of heavy metals and drug glutathione helps cure diseases of the blood and liver.
Glutathione protects cells in several ways.It neutralizes oxygen molecules before they can harm.Together with selenium, it forms the enzyme glutathione peroxidase, hydrogen peroxide neutralizing.
Glutathione protects not only individual cells but also the tissues of the arteries, brain, heart, immune cells, kidneys, lens, liver, lungs, and skin against oxidation.It plays a big role in the prevention of cancer, especially cancer of the liver;slows the aging process.
Coenzyme Q10 - an antioxidant similar to vitamin E. It plays an important role in cellular energy production, a strong immunological stimulant, increases blood circulation, has the ability to slow down the aging process, it is useful for the cardiovascular system.
Melatonin The hormone melatonin is produced by the pineal gland located in the brain.As a child, melatonin is produced in large quantities.Shortly before puberty, its production begins to decline with age has been steadily declining.
Melatonin is the most effective of all open antioxidant to date because it is able to penetrate any part of the body.Melatonin protects cells from an unusually wide range of adverse effects.In the cell, it provides special protection yadru- central structure containing DNA.With it, the damaged cell has the ability to repair itself.Melatonin also stimulates the enzyme glutathione peroxidase.Natural melatonin production in the body can inhibit the use of alcohol, lack of sleep and lack a long stay in the dark.Melatonin contribute protein, niacinamide, vitamin B6 and B12, acetyl-carnitine.
oligomeric proanthocyanidins (OPC) - a naturally occurring substance, unique flavonols, which have potent antioxidant effects and excellent bioavailability.Clinical trials have shown that the OPT can be 50 times stronger than vitamin E and 20 times - bioavailable vitamin C for antioxidant activity.Furthermore, they strengthen the connective tissue and reduced, including the cardiovascular system tissue, alleviate allergic and inflammatory reactions.OPC found in a variety of plants, but their main istochniki- pine bark extract (Pycnogenol) and grape seed extract.
Selenium Selenium - an important component of the antioxidant enzyme glutathione peroxidase.This enzyme is dangerous hydrogen peroxide and turns it into water.It is especially important for the blood cells, heart, liver and lungs.Selenium stimulates increased antibody response to infection.
Zinc Zinc is necessary to maintain proper concentration of Vitamin E and promotes absorption of vitamin A. In addition, zinc glands and promotes the immune system.
Cysteine Cysteine is essential for the synthesis of glutathione - neutralizer of free radicals.It is used by the liver and lymphocytes to detoxify chemicals and other poisons.This is a powerful converter of alcohol, tobacco smoke and pollution Commemorative factors that suppress the immune system.Supplements containing L-cysteine, increase the number of protective enzymes, reducing cell loss which is characteristic of the aging.
