The immune system is our first line of defence against external threats like viruses and bacteria. To function at its best, it requires a proper supply of essential micronutrients, including selenium.

This trace element plays a vital role in supporting the body’s natural defences, helping maintain the normal functioning of the immune system and protecting cells from oxidative stress.

However, selenium absorption through diet is not always optimal, due to factors such as the poor bioavailability of some forms of selenium or issues with absorption in the intestines.

To address these challenges, PharmaNutra has developed UltraSel®, an innovative form of selenium (sodium selenite containing 0.3% selenium) with Sucrosomial® Technology, designed to ensure high bioavailability and excellent tolerability.

 

Selenium and the immune system: an essential link

Selenium performs multiple functions at the immune level. This micronutrient contributes to the production and proper functioning of selenoproteins, essential proteins that regulate several biological processes, including the immune response and protection from oxidative stress.

In addition, selenium acts as an immunostimulant. It promotes the proliferation and activation of T cells, which are key to the body’s defence against infections, as well as enhancing the activity of natural killer (NK) cells and stimulating other innate immune cells.

Its antioxidant action helps reduce damage caused by free radicals, protecting immune cells and ensuring a more effective immune response.

Selenium deficiency has been linked to increased susceptibility to infections and a diminished ability of the body to combat pathogens.

 

Other benefits of selenium

In addition to its vital role in the immune system, selenium serves many other functions essential for the body’s overall well-being.

It supports thyroid health by aiding in the proper functioning of thyroid hormones, which regulate metabolism and energy expenditure. Selenium also contributes to cardiovascular health due to its antioxidant properties, helping to reduce oxidative stress in blood vessels.

Moreover, selenium is crucial for maintaining healthy skin and hair, as it protects cells from environmental damage and promotes their regeneration.

 

UltraSel®: optimum assimilation thanks to Sucrosomial® Technology

The innovation of UltraSel® lies in the use of Sucrosomial® Technology, which encapsulates sodium selenite molecules in a matrix of phospholipids and sucrose esters (Sucrosome®). This protective matrix shields the selenium from the harsh gastric environment and enhances its absorption in the intestines.

This advanced technology offers several benefits:

• it increases the bioavailability of selenium compared to traditional forms;
• it reduces the risk of gastrointestinal effects associated with selenium intake;
• it ensures prolonged and effective action through a targeted, controlled release.

As a result, UltraSel® maximises the benefits of selenium for the immune system, making it an ideal choice for those seeking effective and well-tolerated nutritional supplementation.

 

Why choose UltraSel®?

Thanks to its advanced formulation, UltraSel® represents a breakthrough in selenium supplementation. Compared to traditional forms, it offers enhanced absorption and an optimal safety profile, effectively supporting the immune system and protecting cells from oxidative stress.

In a world where health and well-being are becoming increasingly important, choosing high-quality functional ingredients like UltraSel® means investing in your immune health with a scientifically advanced and innovative approach.
