Aphanizomenon flos-aquae (dietary supplement) therefore not suitable for use as a B source for humans. "Aphanizomenon flos-aquae" contains minerals and trace minerals (including calcium, chloride, chromium, copper, iron, magnesium, manganese, phosphorus, sodium, and zinc). Whether or not AFA microalgae contain a balance of bioavailable minerals and trace minerals depends on the mineral content of their growth environment. AFA" "is approximately 60% protein by dry weight. Approximately 45% of the lipids (fats) of AFA are essential fatty acids. "Aphanizomenon flos-aquae" contains a balance of both linoleic acid (LA, an omega-6 fatty acid) and alpha-linolenic acid (ALA, an omega-3 fatty acid). Researchers at Massachusetts General Hospital
