Selenium is said to have two sides. Both its deficiency and excess is very dangerous to health and that is why it should be supplemented with caution. Experts indicate that safe selenium intake is up to 400 mcg daily.
The manufacturer recommends to take 1 capsule, i.e. 200 mcg of selenium, to prevent deficiencies. While following a well-balanced diet, you can take only 1 capsule every other day.
The supplement contains also other nutrients. Some of them are fat-soluble. Because of that, it is suggested to take the supplement with a meal. If you are taking also a zinc supplement, take it within several hours of taking this supplement.
Vitamin E (tocopherol) is a fat soluble. Due to its antioxidant action, it is a protection of other vitamins (e.g. Vitamins A). Protects the body against free radicals, strengthens the walls of blood vessels and its capacity, causing their dilation and dissolution of blood clots. With the reduction of coagulation, it is used as an antiatherogenic medicine, it allows for the proper course of pregnancy. In cooperation with selenium it slows the ageing process of cells, strengthening connective tissue. In the food it is present in whole-grain bread, sprout and grains, vegetable oils (soybean, sunflower), soya beans and sunflower seeds, vegetable fat and hen egg yolks. Also it is used in sports medicine in the form of nutrients and supplements.
Vitamin E deficiency reduces building of red blood cells, results in changes in muscle and disorders of pregnancies.
Dosage: for children, 0.5 mg / 1 kg of weight; for adults 10-30 mg per day.
Selenium (element, chemical symbol Se, atomic no. 34, from chalcogenide, it is present in several allotropic forms). It is supplied the body with food in the form of seleno-amino acids (selenomethionine - gathering supplies, and selenocysteine – a component of glutathione peroxidase, deiodinase and seleno-proteins). Regulates the functioning of the thyroid gland. It affects the growth and development, including sexual development (by increasing production and sperm motility). It affects the flexibility of the tissue, removes some of the toxins from the body and destroys cancer cells and reduces the severity of menopause in women. Natural products containing selenium are seafood (sea fish, oysters, bladderwrack) and vegetable products (broccoli, onions, wheat germ, bran, tomatoes) and animal products (poultry, eggs). It is also included in the composition of vitamin-mineral and mineral supplements. Selenium supplementation is recommended as a dietary supplement of active people having diet poor in this element, and as a factor increasing the body's immunity.
Selenium deficiency increases the risk of developing cancer and heart disease. Symptoms of selenium deficiency are: cardiomyopathy, growth stoppage, disorders of detoxification processes which may lead to damage to the kidneys and liver.
An excess of selenium can lead to selenosis (the disease, the symptoms are: loss of hair, nail cracks, lesions).
daily demand of selenium for pregnant women 65 mcg; nursing mothers 75 mcg; men 7 mcg.
What is Brassica oleracea?
Brassica oleracea is a plant species of the crucifer family, which includes broccoli, cauliflower, kale, cabbage, Brussels sprouts and other vegetables.
Crucifers are known for their great health-promoting potential. The components beneficial for the human organisms are, for example, sulphoraphane, indole-3-carbinol (I3C), diindolylmethane (DIM), and a large amount of vitamins and minerals. Its beneficial effects can be noticed especially in the case of too high oestrogen levels, and even in the process of carcinogenesis induced by them. It results from its potential to reduce aromatase production, which is possible thanks to the fact that sulphoraphane can inhibit aryl hydrocarbon receptors (AHR), while diindolylmethane can modulate oestrogen metabolic pathways. Crucifers can be beneficial for the health of the entire organism thanks to its ability to reduce reactive oxygen species, which decreases the damage induced by them, as well as to reduce inflammations, which can lead to serious complications when chronic.
