SELSAF® 3000

SelSaf® 3000 is the only organic selenium-enriched yeast to combine two complementary selenium forms: L-selenomethionine and L-selenocysteine. L-selenomethionine is efficiently stored in muscle and body proteins as a selenium reserve for future physiological needs, while L-selenocysteine is immediately available for the synthesis of antioxidant enzymes such as glutathione peroxidase. This unique dual-action selenium source provides both long-term selenium reserves and rapid antioxidant support, helping livestock better manage oxidative stress throughout production.

Oxidative stress can increase during periods of rapid growth, reproduction, heat stress, disease challenge or production transitions. SelSaf® 3000 addresses this through its dual selenium profile. L-selenocysteine directly supports the production of selenium-dependent antioxidant enzymes that neutralise damaging free radicals, while L-selenomethionine builds selenium reserves within muscle proteins to maintain selenium availability over time. Together, these complementary forms help provide more consistent antioxidant protection than products supplying a single organic selenium source.

SelSaf® 3000 is suitable for use across multiple livestock species, including poultry, swine, ruminants, equine and aquaculture, wherever selenium supplementation is required within local regulations. Its highly bioavailable organic selenium supports antioxidant defence, immune function and reproductive performance throughout different stages of production. The dual-action selenium profile makes it particularly valuable during periods of increased oxidative stress, helping animals maintain health, resilience and productive performance regardless of species.

Not all selenium sources behave the same once absorbed. L-selenomethionine can be incorporated into body proteins, creating a natural selenium reserve that can be mobilised when needed. L-selenocysteine, meanwhile, is the biologically active form required to produce key antioxidant enzymes that protect cells from oxidative damage. By naturally providing both forms, SelSaf® 3000 delivers immediate functional antioxidant support alongside longer-term selenium storage, offering a broader nutritional approach than products based on a single selenium form.

Yes. Research has shown that organic selenium sources such as SelSaf® 3000 can improve the transfer of selenium into eggs and milk compared with inorganic selenium sources. Its unique dual-action selenium profile provides L-selenomethionine for storage in body proteins and L-selenocysteine for immediate biological function, supporting both animal selenium status and the deposition of selenium into animal-derived foods. This can help producers enhance the nutritional value of eggs and milk while maintaining animal health and productivity.
