Name of the invention: A natural substance based antioxidant and chemoprotective agent and its method of production The natural substance based antioxidant and chemoprotective agent consists of two parts a vegetable component which is prepared from dry extracts from the fruits of Vitis vinifera representing 20 to 60 % of weight, from Emblica officinalis 15 to 55 % of weight, from Phoenix dactylifera 10 to 55 % of weight, from the haulms of Phyllanthus amarus 5 to 20 % of weight, Andrographis paniculata from 4 to 20 % of weight and from the entire plant of Cichorium intybus or from its parts 7 to 20 % of weight and this component is supplemented by one part of the vitamin-mineral component consisting of magnesium of 50 to 70 % of weight, zinc 2.8 to 3.4 % of weight, molybdenum 0.01 to 0.02 % of weight, chromium 0.01 to 0.02 % of weight, selenium 0.01 to 0.02 % of weight, vitamin C 20 to 30 % of weight, vitamin E 3.50 to 4.10 % of weight, pyridoxine 0.40 to 0.50 % of weight, thiamine 0.30 to 0.40 % of weight, riboflavine 0.40 to 0.50 % of weight, nicotiamide 5.00 to 5.50 % of weight, cyanokobalamin 0.0008 to 0.001 % of weight and folic acid 0.06 to 0.07 % of weight. The natural substance based antioxidant and chemoprotective agent is produced in such a way that the component is homogenised individually and then mixed in proportion to the vegetable component 2 parts + 1 part of the vitamin-mineral component (recalculated into active elements) whereas after the final homogenisation, suitable capsules are filled with the solid form of the agent so that the consumer pack does not exceed the daily recommended doses (DRD) or is adjusted in a different suitable solid form while maintaining the same conditions for DRD whereas the liquid form arises after the solid form has been dissolved in the required amount of water so that a solution of 0.15 to 0.3% of weight arises. The liquid form of the agent can contain 0.015 to 0.04 % of caffeine weight in the final agent. The agent
