Selenium is the 21st amino acid, present in the body as Selenocysteine (Sec). Antioxidants that contain selenoproteins are involved in the synthesis of certain hormones in the body. Selenium deficiency activates malignant cells that in turn increase the risk of malignant neoplasms.


The recommended daily intake of selenium is 54-108 micrograms per day for adults. For people engaged in physically demanding activities this figure is higher – up to 150 mcg per day. It is important to understand that the human body does not produce selenium and has to get it from food, such as: nuts (e.g., Brazil nuts contain very high amounts of selenium), liver, kidneys, fish or seafood. If you cannot maintain a healthy balanced diet and your schedule is far from ideal, Selenium 100 mcg by Grassberg is a great way to compensate for a deficiency of selenium in your body. This product can be taken regularly due to its balanced dosage of the active ingredient. This is important because excess selenium in your body can cause a reverse effect: brittle hair and nails, neuropathy, diarrhea. 


At the Warsaw University of Life Sciences, Department of Food Biotechnology and Microbiology, Dr Marek Kieliszek described in his article “Selenium supplementation in the prevention of coronavirus infections (COVID-19)” how the amount of selenium in the body can influence the level of protection against COVID-19.
