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.
What did the diabetes trial actually test?
A small randomized trial in 49 people with type 2 diabetes reported improved blood-glucose measures with an AFA-containing regimen. It combined an AFA extract with an enzyme and botanical blend, so any benefit cannot be assigned to AFA alone. The paper also reports inconsistent intervention durations. 1
This is a preliminary signal for a particular combination, not evidence that generic algae tablets treat diabetes. Several inflammatory markers and blood lipids did not show a clear improvement. 1
