A study in reported in the Journal of Toxicological Sciences found that chlorella, a unicellular green algae has been used for many years as a nutritional supplement, can help flush methylmercury from your system.
Mice fed methylmercury were given chlorella, and the amount of methylmercury excreted in their urine and feces was about twice the amount excreted by mice not given chlorella.
Methylmercury is a neurotoxic compound widely used in industrial applications. It accumulates in fish, which has led to widespread alert against fish consumption by pregnant women.
The journal reports that these results suggest that the intake of chlorella may induce the excretion of Hg [mercury] both in feces and urine although it does not affect mercury absorption from the gastrointestinal tract. The effect of chlorella on the tissue mercury accumulation may become evident in a long-term experiment.
It is already known that chlorella has the ability to absorb some metals and has been used in waste water treatment to reduce contaminated heavy metals.
