Blue-green algae
Blue-green algae are cyanobacteria that grow in water. One supplement ingredient is Aphanizomenon flos-aquae (AFA) from Upper Klamath Lake in Oregon.
Do a few tablets add much nutrition?
The German Verbraucherzentrale notes that the amounts of protein, vitamins, minerals and fatty acids supplied by AFA supplements are small. A nutrient-rich description of the dried material can therefore give a misleading impression of what a usual serving contributes. 1
