Spirulina is a form of cyanobacterium, some of which are known to produce toxins such as microcystins, BMAA, and others. Some spirulina supplements have been found to be contaminated with microcystins. Microcystins can cause gastrointestinal disturbances and, in the long term, liver CANCER. The effects of chronic exposure to even very low levels of microcystins are of concern, because of the potential risk of CANCER.
Due to very high Vitamin K content, patients undergoing anticoagulant treatments should not change consumption patterns of Spirulina without seeking medical advice to adjust the level of medication accordingly.
As all protein-rich foods, Spirulina contains the essential amino acid phenylalanine (2.6-4.1 g/100 g), which should be avoided by people who have the rare genetic disorder phenylketonuria, where the body cannot metabolize this amino acid and it builds up in the BRAIN, causing DAMAGE.
Organic certification
Until recently, much spirulina was certified organic. In 2002, the USDA's National Organic Standards Board voted to disallow the use of Chilean nitrate. They granted a three-year window to spirulina producers, which expired in 2006.
