Is spirulina safe for consumption?
Spirulina is unique among blue-green algae because it has a long history of safe use. The Aztecs consumed spirulina in Mexico over five centuries ago. Indigenous people consume spirulina growing in African Lakes today. For the past 20 years, millions of people around the world have enjoyed it as a safe food supplement.
