Dangers of Blue-Green Algae Supplements

Research highlights significant health risks associated with blue-green algae supplements, particularly AFA from Klamath Lake. This algae has been linked to the production of harmful toxins like cylindrospermopsin and saxitoxin, which can cause liver and neurological damage, respectively. Historical sampling revealed that a vast majority of AFA tested exceeded safety limits set by Oregon State, indicating widespread contamination issues. Given that these toxins can vary greatly between batches, even brands claiming safety may offer unpredictable risks to consumers.
