Chemlock Nutrition Launches Nutrilock® SelenoSure™: A Guaranteed 100% L-selenomethionine Source for Animal Nutrition

Cincinnati, OH – August 5, 2026 – Chemlock Nutrition announces the launch of Nutrilock® SelenoSure™, the first US-researched selenium source guaranteed to contain 100% L-selenomethionine – the form of selenium that animals absorb directly and store as reserves for times of increased selenium demand.

Because Nutrilock® SelenoSure™ contains only pure L-selenomethionine, animals can utilize it immediately without a conversion step or the associated loss in bioavailable selenium. This consistency stands in contrast to selenium yeast products, whose L-selenomethionine content can vary in every batch, and selenomethionine analog products, which require biological conversion before they can be utilized.

“The form in which selenium is delivered determines how effectively animals can use it,” said Dr. Grant Shouldice, Vice President of Chemistry and Innovation. “When you’re limited to 0.3 ppm of selenium, every unit matters. Nutrilock® SelenoSure™ gives nutritionists the confidence they are maximizing their selenium supplementation.”

Unlike inorganic selenium sources, L-selenomethionine is stored in muscle tissue and gives animals a selenium reserve available during periods of stress, rapid growth, reproduction, or other times when selenium demand increases.

Nutrilock® SelenoSure™ is manufactured under The Chemlock Standard™ quality program and is suitable for use across multiple species, including dairy, beef, layers, breeders, turkey, broilers and swine.

Why Nutrilock® SelenoSure™

  • 100% L-selenomethionine: the bioactive form, guaranteed identical in every batch
  • Stored in body tissue so animals have a selenium reserve when they need it most
  • Supports immune health, antioxidant protection, and reproductive performance
  • Works across multiple species
  • Manufactured to rigorous quality standards and backed by The Chemlock Standard™
