BMAA is only produced by certain kinds of Spirulina grown in natural lakes and unregulated water sources. Our Spirulina is of the Arthrospira Platensis variety, and is not related to the BMAA-producing strain. Sevenhills Wholefoods' Organic Spirulina is actually grown in carefully monitored cultivation ponds, where conditions are constantly observed. In addition to this, our Spirulina is spray-dried during production, in which no cell capable of producing BMAA can survive.
