9. Diabetes Control
Spirulina has been shown to have benefits in the prevention and management of diabetes as well. A 2018 review study found supplementing with spirulina significantly lowered people’s fasting blood glucose levels. “It contains around 4 grams of protein per tablespoon, which is good for blood sugar control and diabetes control,” says Young, who recommends sprinkling it into everyday favorites, such as coffee drinks and acai bowls.
Though these early findings are promising, Gans cautions that they should be kept in proper perspective. “I would never say to start adding spirulina and go off any medication that you’re on,” she says. “But, if it’s looking like you’re starting to have some insulin resistance, perhaps this could be one tool out of many in your toolbox.”
10. Reduces Allergies
Spirulina supplementation is also linked to protection against allergic reactions, as it can help stop the release of histamines, which cause allergy symptoms. One study found people with allergic rhinitis who consumed 2 grams of spirulina a day experienced significant improvement in symptoms like nasal discharge, sneezing, nasal congestion and itching.
