Nutrilock® SelenoSure™ guarantees
100% L-SeMet in every batch,
unlike fermented selenium.
Competitor selenium yeast sources show wide variability in
L-SeMet concentration, leaving producers uncertain about how much Se their animals actually receive. With SelenoSure™, you get a reliable, high-quality selenium source that delivers the same exceptional standard every time.
Zero Conversion Steps = Ready Right Now
Nutrilock® SelenoSure™ delivers only pure L-Selenomethionine with no conversion step required. This ready-to-use form is available for immediate use by the body.
Best Buds – Se and Vitamin E
Se and vitamin E work synergistically to reduce inflammation. Increasing vitamin E alone, without adequate Se, won’t achieve the desired effect. Supplemental Se can reduce the need for increased dosage of vitamin E. Together, they make quite a team!
Nutrilock® SelenoSure™ is the Superior Choice
