1. Very Nutritious
Protein: Chlorella is 50–60% protein. What's more, it's a complete protein source, meaning it contains all nine essential amino acids (3, 5Trusted Source).
Vitamin B12: Some chlorella varieties may also contain vitamin B12, but more studies are needed (6Trusted Source).
Iron and vitamin C: Chlorella can be a good source of iron. Depending on the supplement, it may provide anywhere from 6–40% of your daily need. It's also an excellent source of vitamin C, which helps you absorb iron (1Trusted Source, 3, 7).
Other antioxidants: These tiny green cells provide a wide range of antioxidants (1Trusted Source, 3).
Other vitamins and minerals: Chlorella provides small amounts of magnesium, zinc, copper, potassium, calcium, folic acid and other B vitamins (1Trusted Source, 3, 8).
Omega-3s: As with other algae, chlorella contains some omega-3s. Just 3 grams of chlorella delivers 100 mg of omega-3s (8).
Fiber: In large quantities, chlorella can be a good source of fiber. However, most supplements don't provide even 1 gram of fiber per dose (1Trusted Source, 8).
