Algin, also known as sodium alginate, is a natural polysaccharide extracted from brown seaweed. Its use in supporting or treating issues related to environmental pollution is scientifically grounded, particularly due to its ability to bind heavy metals and radioactive substances. Several laboratory and animal studies have demonstrated that alginates can chelate (bind to) toxic metals such as lead, mercury, and cadmium, as well as radioactive isotopes like strontium and cesium. This property allows alginates to facilitate the excretion of these contaminants from the body, potentially reducing their bioaccumulation and harmful effects.

One of the primary mechanisms involves the high affinity of alginates for divalent and trivalent metal ions, enabling them to sequester these pollutants in the gastrointestinal tract and prevent their absorption. Some clinical research, though limited, has shown reduced uptake of radioactive strontium in humans when alginate compounds are administered. Furthermore, algin has been used in environmental applications to remove heavy metals from wastewater, highlighting its binding capabilities outside the human body as well.

However, while these properties are well-established in laboratory settings, direct clinical evidence supporting the use of algin supplements for detoxifying humans from environmental pollutants is less robust, and more high-quality human trials are needed. Overall, the scientific basis for algin’s use in supporting detoxification from environmental pollutants is promising but not yet definitive.
