Is Sel-Plex more or less toxic than inorganic selenium?
Although more digestible than inorganic selenium, selenium in Sel-Plex form is actually much safer both to horses and humans. The organic selenium compounds that plants and yeast produce are nature’s way of providing a potentially toxic element in a safe form. Selenoamino acids are absorbed from the gut via amino acid pathways, which necessarily limits excessive uptake. In contrast, selenite Se is passively absorbed, which allows rapid and unregulated uptake of toxic levels of selenium. Sel-Plex Se is also much safer to handle by those mixing feeds. Sodium selenite is extremely toxic because it is absorbed through the skin. In contrast, the selenocompounds in Sel-Plex are not absorbed on contact, which increases safety against the most common selenium toxicity problem: exposure to human skin in laboratories and feed mills. How does Sel-Plex benefit the broodmare herd? Delivery of a healthy foal, prompt and complete expulsion of the placenta, avoidance of metritis and other periparturie
