Study shows Spirulina fusiformis reduces damaging effects of toxic mercuric chloride on kidneys

The most dangerous form of mercury, methyl mercury, wreaks havoc on the human immune system, altering enzymes and also damaging the nervous system, manipulating coordination and senses like touch, sight and taste.

Sources of toxic mercury pollution include incineration of coal, broken thermometers, medical waste and metal processing. Mercury pollution is also found in gold mines, where it is used as an extracting agent. These environmental sources of mercury pollution contaminate water sources, building up in the food chain of aquatic life. Some fish species are teeming with mercury now.

Sadly, this toxin is packaged and sold to the public in many different forms.
