Selenium is an essential micronutrient attached to the primary structure of protein as selenocystein 1. This selenocysteins facilitates oxidation - reduction reaction involved in many biochemical processes, such as protection against oxidative damage, metabolism of thyroid hormones and DNA synthesis support and conditioning of transcription factors. Daily nutritional need for selenium is about 55 micrograms for adults.

Selenium helps to balance the metabolism in the body. It is a powerful antioxidant, inhibiting the formation of cancer cells and reducing harmful side effects of chemicals and radiation, supporting cancer treatment.

At the same time, selenium helps to reduce toxicity of toxic metals. Selenium, when used in combination with heavy metals such as mercury, lead, arsenic, cadmium ... and a particular protein will lose effect of toxic metals and enhance the process of removing such harmful substances from the body, greatly reducing the risk of forming tumors and cancer.

Selenium is a trace element, essential nutrient for humans. Selenium deficiency causes serious problems. It is a component of more than two dozen  selenoproteins which have an important role in reproduction, metabolism of thyroid hormones, DNA synthesis, and protecting body from oxidative damages and infections (Sundee et al Modern nutrition in Health and Disease 11th Ed. Philadelphia PA Lippincott, Williams and Wilkins 2012:225-37).

An excerpt from the Nordic Cochrane Institute in 2011 gave an obvious conclusion: "The epidemiological studies have shown an inverse relationship between selenium status and risks of colorectal, prostate, lung, bladder, skin, esophagus, and stomach cancer.

The data showed that the group with the highest levels of selenium in their blood have a lower risk of cancer by 31%, and 45% reduced risk of dying from cancer, when compared to those in the group with the lowest level ( Cochrane Database Syst Rev 2011: CD005195)."
