This is known because regularly-collected samples of the algae and the water from which it comes are subjected to a wide variety of scientific analysis and tests. It is important to remember that these testing standards, far exceed those of the U.S. Food and Drug Administration. The samples which are tested are taken daily, and in every batch of product, to ensure that all Blue Green Algae products are safe, pure and healthful. Blue Green Algae, made of Aphanizomenon flos-aquae from Upper Klamath Lake, has not produced a neurotoxin in the fifteen years that Blue Green Algae has been tested. Of greater importance is the constant testing and microscopic examination of the algae being harvested, to make certain no toxic conditions exist.
