Selsaf®3000 is a natural source of highly bioavailable organic selenium, assimilated through active transport. The main compounds of Selsaf®3000 are L-selenomethionine and L-selenocysteine.
L-selenomethionine is incorporated into body proteins as the main selenium storage, and used as a precursor to L-selenocysteine. L-selenocysteine plays an essential role against oxidative stress as a key element ensuring the activity of the antioxidant enzyme glutathione peroxidase.
Selsaf®3000 is obtained from a proprietary yeast strain of Saccharomyces cerevisiae, cultivated on medium enriched with sodium selenite which is bio-transformed into organic form by yeast cells, ensuring a high concentration of organic selenium and a consistent composition.
