Although spirulina is generally considered safe for most people, some people should avoid taking it or consult a health professional before doing so.
People allergic to seafood or sensitive to algae may react to spirulina. In addition, people with an allergic background or a muscular or hepatic vulnerability, or suffering from phenylketonuria, a rare genetic disease, should avoid spirulina because of its phenylalanine content. During pregnancy or while breastfeeding, you should also seek medical advice before taking spirulina supplements.
