| Applications | Selenium-supplement raw-material manufacturing — Se-methylselenocysteine is a naturally occurring, highly bioavailable organoselenium compound found in selenium-accumulator plants (e.g., garlic, broccoli-family vegetables), commonly used as a raw material in selenium dietary-supplement manufacturing |
This compound is a selenium-containing analog of the amino acid cysteine, with a methyl group attached to the selenium atom. It occurs naturally in selenium-accumulator plants and is notable for high peroral bioavailability and favorable pharmacokinetics compared to other organoselenium forms.
This compound is used as a raw-material ingredient in selenium dietary-supplement manufacturing, and as a research compound in cancer-chemoprevention studies.
Compliance note: This is a bulk research/raw-material chemical, not a finished, approved dietary supplement or drug product. Any supplement-manufacturer customers are responsible for ensuring their own finished-product claims comply with FDA dietary-supplement regulations (DSHEA) — selenium-supplement products should not be marketed with disease-diagnosis, -treatment, -cure, or -prevention claims without appropriate regulatory support.
