As one of the trace elements, selenium is a key micronutrient that performs a number of important functions in the processes taking place in our body.
Selenium contributes to to :
- Maintaining healthy hair and nails
- The proper functioning of the thyroid gland and the immune system
- The normal course of spermatogenesis
- Protecting cells from oxidative stress
Why is it worth supplementing selenium?
The distribution of selenium in the earth's crust is uneven, which means that its presence in the diet of individual populations fluctuates and may be underestimated. Therefore, it is worth considering its supplementation, especially in the proven and well-absorbed form, which is L-Selenomethionine Selenium SeLECT®.
Organic Selenium SeLECT® and other forms of selenium
It turns out that not all forms of selenium are created equal. The uniqueness of L-Selenomethionine lies in the fact that thanks to its structure similar to one of the key amino acids - methionine - it is directly attached to proteins in the body through metabolic pathways similar to those for methionine.
In turn, inorganic forms of selenium, such as salts or chelates, are first broken down in the body to elemental selenium. In this form, it is less bioavailable.
A study conducted by the Vanderbilt University Medical Center in 2005 with the participation of people with low selenium intake showed that L-Selenomethionine in the form of Selenium SeLECT® produced by Sabinsa has twice as much bioavailability as sodium selenite. Among the people tested, less than half of the selenium in the form of L-selenomethionine compared to sodium selenite was enough to obtain optimal blood selenium levels.
Another study conducted in 2006 aimed to compare the bioavailability of selenium in the form of L-selenomethionine, sodium selenite and selenium yeast. Among 81 tested people, it was shown that selenium in the form of L-selenomethionine was absorbed to a greater extent than in other forms.
