Spirulina, a blue-green algae, has been explored for its potential in supporting the body against the harmful effects of environmental pollution, particularly due to its antioxidant and detoxifying properties. Scientific studies suggest that spirulina may help mitigate damage caused by exposure to heavy metals (such as arsenic, lead, and mercury), radiation, and certain organic pollutants. Animal studies have shown that spirulina supplementation can reduce oxidative stress and tissue damage induced by environmental toxins, likely due to its high content of phycocyanin, chlorophyll, beta-carotene, and other antioxidants. For example, research published in Food and Chemical Toxicology and Biomedicine & Pharmacotherapy demonstrates that spirulina can decrease markers of oxidative stress and improve organ function in animals exposed to heavy metals or pesticides. Some small human studies also indicate that spirulina may reduce arsenic toxicity and improve antioxidant status in individuals exposed to pollutants. However, most evidence remains preclinical or limited to pilot studies, so while the scientific rationale and early data are promising, more robust clinical trials are needed to confirm these benefits in humans. Spirulina is not traditionally used for pollution detoxification in the historical sense; rather, its modern application is based on emerging scientific research into its bioactive compounds and their protective effects against environmental toxins.
