Contamination Risk

Spirulina can be contaminated with heavy metals, toxins, or bacteria if grown in polluted water, leading to potential health risks. Purchase from reputable sources with contaminant testing is crucial.

Spirulina, a blue-green algae, can pose a contamination risk if cultivated in environments with polluted water sources. Contaminants may include heavy metals (e.g., lead, mercury, arsenic), microcystins (cyanobacterial toxins), and harmful bacteria (e.g., E. coli). Consumption of contaminated spirulina can lead to various adverse health effects depending on the contaminant and its concentration. Heavy metal exposure can cause neurological damage, kidney problems, and other systemic issues. Microcystins can damage the liver and potentially act as tumor promoters. Bacterial contamination can lead to gastrointestinal distress, including nausea, vomiting, diarrhea, and abdominal pain. The severity of the effects depends on the level of contamination and the individual's susceptibility.
