Is spirulina safe for consumption?
Yes! Spirulina is safe and has a long history of safe use, including early African and Mexican civilizations. For the past 20 years, millions of people around the world have used it as a safe dietary supplement. In addition, the United Nations and the World Health Organization recognize spirulina as safe and particularly nutritious. However, in recent years, there have been large commercial farms that are not as concerned about the quality. They market spirulina contaminated with heavy metals. So carefully choose the spirulina you buy and inquire about its origin. Not all spirulina is of equal quality.
