There are some important things to take into account before purchasing a selenium supplement. Many consumers are not aware of the vast quality differences and trust that one selenium supplement is every bit as effective as another. Quality is certainly something you should look into before choosing your product. Otherwise, you may end up with a product that does not do you much good.
Different forms of selenium
Selenium comes in two forms: Organic and inorganic. The body can absorb both kinds, but studies show that organic selenium generally reaches the different tissues faster and more effectively than it is the case with inorganic selenium. In other words, organic selenium is more bioavailable to the body.
However, the fact that a supplement contains organic selenium is no guarantee of its bioavailability. Many other factors influence the absorption of selenium in blood and tissue. The most reliable way to find a selenium supplement that is worth trusting is to choose one that has documentation.
Nearly 90% gets absorbed
The Danish company Pharma Nord has developed a unique selenium yeast called SelenoPrecise. Exhaustive scientific research documents that the body absorbs 88.7% of the selenium content in this selenium yeast and the bioavailability is also good (74% of the absorbed selenium is retained in the body). More than 40 published scientific studies have been conducted with the SelenoPrecise raw material, which is considered one of the most well-documented selenium sources available.
The only preparation with SelenoPrecise
BioActive Selenium + Zinc is the only selenium preparation in Ireland that contains SelenoPrecise. With the 100 micrograms of selenium that each tablet provides (together with zinc and vitamins A, B6, C, and E), the body gets a selenium dosage that scientists consider adequate for good health.
More than 20 different organic selenium species
SelenoPrecise consists of more than 20 different types of organic selenium and provides you with the same natural variety of selenium sources that you would get from eating a balanced diet. In comparison, most organic selenium products on the market typically only contain one selenium source.
Selenium yeast is far safer
A large number of selenium supplements contain inorganic selenium because it is much cheaper to manufacture. However, according to the European Food Safety Authority (EFSA), organic selenium yeast is significantly safer to ingest than inorganic selenium. This alone makes organic selenium yeast a better choice for daily consumption.
Preferred by scientists
The Swedish scientists who conducted the groundbreaking KiSel-10 study that was published in the International Journal of Cardiology in 2013 specifically chose SelenoPrecise for their research project. This is because they wanted to use a selenium source with properly documented bioavailability and safety. The study, which was carried out on a large group of older men and women, lasted for four years. The treatment group received 200 micrograms of SelenoPrecise and 200 mg of coenzyme Q10 (BioActive Q10) daily, while the control group took matching placebo.
