Emma Laing, clinical professor in the College of Family and Consumer Sciences’ nutritional sciences department and director of dietetics, spoke with Verywell all about chlorella, the algae powder packed with omega-3s.
Chlorella is a green freshwater microalgae rich in protein, fiber, vitamins, minerals and omega-3 fatty acids. It also contains chlorophyll, which lends its signature green color and antioxidant properties. It’s been compared to the high-protein blue-green algae spirulina, a popular juice bar ingredient that adds a natural blue hue to smoothies and bowls.
“Both chlorella and spirulina have been marketed to help with various conditions — from cardiometabolic health and macular degeneration to dental infections and diagnosed mental illnesses,” Laing said.
It is important to consult a health care provider before starting new dietary supplements, including chlorella or spirulina. Those who choose to consume it can easily add chlorella powder to a smoothie, but like spirulina, some people complain that chlorella has a “fishy” taste.
“Taking chlorella in tablet or capsule form or combining it with other flavorful ingredients can help mask the taste,” Laing said.
Alternatively, try adding chlorella powder to apple sauce, salad dressing, coffee, chai or matcha to improve the flavor.
