Todd deveoped a "Nutri-plex" multi for his patients, the ingredients of which I can't find, but in 2006 eight years after his death it was "improved" by a colleague and became "Eye-Max" which lists 200 mcg "selenium amino acid chelate" and elsewhere "selenium amino acid complex". I read, technically speaking, selenmethionine is a chelate of selenium, but other formulations listing selenium chelate never seem to specify selenomethionine. They usually don't specify at all, `tho I have seen one instance of selenium glycinate.
An info sheet dated 2003 from Eburon-organics who manufacture selenium compounds, says with maybe a touch of marketing:
Anything called a “chelate ” or “chelated selenium” is to be avoided!!!
True chelates of selenium do not exist in nature and any supplement so labeled is pure
fraud. Do not buy them as you do not know what the selenium form is really contained
within. In the organic selenium amino acids, L-selenomethionine and SEMC
TM Selenium, the selenium is fully integrated into the amino acid itself and is not
“chelated”.
I'll let the chemists work out the semantics. Mfrs of "Eye-Max" might give you more info and we may infer that is the form Dr. Todd used. If it was inorganic, it makes me wonder how many of the upper dosages he cites were from inorganic forms, too, and whether they should be halved for an absorption equivalent to an organic form?
But the more I read there seems to be a consensus around selenomethionine as a superior form that may not have existed in the 1980s and 90s when Dr. Todd developed his multi.
Here is a link to Eburon's release which is interesting reading:
