On his first day of life an infant is hospitalized with seizures the researchers concluded that his mother’s daily spirulina use starting in the fourth month of pregnancy was likely to blame I’ve talked previously about the liver and nerve toxins present in many spirulina supplements but the supplement company swear up and down the spirulina doesn’t produce these toxins and they may be right but if spirulina doesn’t produce toxins how is it that toxins have repeatedly been found in spirulina supplements it appears to be contamination of spirulina with toxin producing blue-green algae so for example if you look at the new US forma copia safety evaluation of spirulina they conclude that the available evidence does not indicate a serious risk or other public health concern when spirulina is properly identified formulated and used ah but that’s the catch you collect spirulina in some open Lake and you have no idea what other algae are going to crop up the researchers report all sorts of adverse reactions and people taking spirulina products but they attribute these issues to non spirulina algae toxin contaminants within spirulina supplements known to be toxic to the liver and cancer-causing so unless there’s third-party testing of each batch with which no company could presumably afford to do I continue to encourage people to avoid spirulina products.
