Selsaf: Natural source of organic selenium


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.

Key benefits

Milk production

Cow, goat, ewe, sow, mare, female rabbit

↑ resistance to oxidative stress
↑ recovery after pathological event
↑ Se content in colostrum and milk
↑ transfer of Se from mother to its offspring via colostrum and milk
↑ selenium milk enrichment for functional food

Egg production

Layers, breeders

↑ resistance to oxidative stress
↑ recovery after pathological event
↑ Se content in eggs
↑ hatchability
↑ selenium egg enrichment for functional food


Dogs, cats

↑ resistance to oxidative stress when ageing or in inflammatory conditions

Meat production

Beef, pig, lamb, poultry

↑ resistance to oxidative stress
↑ recovery after pathological event
↑ Se content in meat
↑ meat quality: higher acidification after slaughtering, improved tenderness
↑ selenium meat enrichment for functional food

Aqua production

Fish, shrimp

↑ resistance to oxidative stress
↑ recovery after pathological event
↑ filet quality (lipid preservation)
↑ maintenance of anti-oxidative activity in fishmeal replacement strategy
↑ gamete protection and fertility


↑ resistance to oxidative stress in transportation, during reproduction or physical training

Mode of action

  • Dual action on selenium metabolism pathways:
    • L-selenocysteine, key element in the structure of antioxidant enzymes, especially glutathione peroxidase
    • L-selenomethionine, incorporated in body proteins as selenium pool
  • Improves the metabolic anti-oxidative status of animals
  • Higher bioavailability of natural selenium compared to other synthetic or inorganic selenium sources
