Re: Best form of selenium?


Hi mumnz,

Good find...

I have taken selenomethionne yeast free most of my iodinated life.(6 years) I have taken SeMC selenium too.

I have started the SelenoExcell Selenium as it is organic and is the yeast form. I have felt fine so far...

Watch out for some of the synthetic selenomethionne as it has L-form and D-form only suitable for animals.

The L-form is most suitable for humans.

Composition

Commercial selenium yeast supplements contain from about 1,000 to 2,000 micrograms of selenium per gram of supplement. This selenium is in the form of selenomethionine, a specific selenium-containing amino acid. All amino acids occur in two different three-dimensional forms: an "L" form and a "D" form, which are essentially mirror images of each other. The human body can only metabolize the L-amino acid form.

Synthetic selenomethionine supplements are also available, but they are slightly less effective than yeast-selenium. While synthetic versions contain more than 90 percent selenomethionine in the L-form, they also contain some selenomethionine in the D-form. Synthetic selenomethionine, containing mixtures of L- and D-forms, are suitable for use in animal feeds, but selenium yeast is preferable for human supplement.

Quality Concerns

The quality of selenium supplements over the years has been questionable. Some selenium yeast products have been found to contain inorganic selenium instead of selenomethionine. Other supplement products contain "selenium proteinates" or "selenium amino acid chelates," which are chemically ill-defined. Supplements that contain both sodium selenite, an inorganic form of selenium, along and vitamin C may react with each other, causing the formation of elemental selenium, which may not be as beneficial to the body as the selenomethionine provided by selenium yeast.
