Spirulina, a blue-green algae, has been investigated for its potential to support the treatment of lead poisoning, with some scientific evidence supporting its use. The interest in spirulina stems from its antioxidant properties and its capacity to bind heavy metals, potentially reducing oxidative stress and mitigating the toxic effects of lead in the body. Several animal studies have shown that spirulina supplementation can decrease lead-induced oxidative damage and enhance antioxidant enzyme activity. For example, research in rats exposed to lead demonstrated that spirulina could reduce lead accumulation in tissues and improve biomarkers of oxidative stress and organ function.

In humans, the evidence is limited but suggestive. A small pilot study published in 2006 evaluated the effects of spirulina (combined with zinc) supplementation in children exposed to chronic arsenic poisoning, showing some benefit in reducing arsenic levels. Although this study focused on arsenic rather than lead, it lends plausibility to the use of spirulina for heavy metal detoxification. There are few direct clinical studies on spirulina and lead poisoning in humans, and most available evidence comes from animal models.

In summary, while there is some early scientific validation—primarily from preclinical studies—indicating that spirulina may help mitigate lead toxicity, robust clinical trials in humans are lacking. As such, the evidence is promising but currently insufficient to recommend spirulina as a primary treatment for lead poisoning outside of supportive or adjunctive use.
