SelSaf 3000 is a natural source of highly bioavailable organic selenium designed to increase your cattle's productive and reproductive performance. The main compounds of SelSaf 3000 are L-selenocysteine (which plays an essential role against oxidative stress as a key element that ensures the activity of the antioxidant enzyme glutathione peroxidase) and L-selenomethionine (precursor to L-selenocysteine and is incorporated into muscle proteins for posterior availability within selenium reserves of the organism). 

Selsaf 3000 is obtained from a specific yeast strain of Saccharomyces cerevisiae, cultivated in an environment enriched with sodium selenite which is bio-transformed by yeast cells.
