Nomination Summary for Blue-green algae supplements (N20040)
Nomination Date: 09/00/2000
Rationale: Blue-green algae supplements containing cyanobacteria are believed to be taken by over a million consumers. Measurable levels of microcystins, a potent hepatotoxin and suspected liver carcinogen, and anabaena, which contain possible neurotoxins, have been found in the supplements. It is suspected that some toxic metabolites found in cyanobacteria may be tumor promoters. Also, there is a lack of information re the chronic toxicity of cyanobacteria metabolites that are not acutely toxic.
