Piscataway, NJ -
Sabinsa Corporation's R & D staff have developed and
validated an HPLC assay procedure which was also recently
reviewed and approved by the United States Pharmacopeial
Convention. As a courtesy,
Sabinsa has sent this method to the leading
analytical labs that service the dietary supplements industry.
Over the past few years in marketing its Selenium
SeLECT ingredient, Sabinsa has encountered several selenium
containing products claiming to provide
L-(+)-Selenomethionine. HPLC analysis of a
number of commercially available samples offered as L-(+)-Selenomethionine
revealed that the majority are spurious. A physical mixture
of an inorganic or organic selenium salt with methionine
does not make L-(+)-Selenomethionine.
"It is part of our ongoing commitment
to raise the consciousness and quality of dietary supplement
ingredients." stated company President Todd Norton.
Those companies wishing to perform this test
in house, a reference standard is available from Sigma-Aldrich
cat. # 47,394-4.
Sabinsa's Selenium SeLECT is currently the
focus of a large scale prostate cancer study funded through
the National Institute of Health's (NIH)
National Cancer Institute (NCI). It is the
only selenium source being administered in the study. A
second study recently was undertaken to evaluate selenomethionine's
potential role in Alzheimer's patients.
The USP monograph for Selenomethionine is based
on Sabinsa's Selenium SeLECT® brand L-(+)-Selenomethionine
