Chlorella

Chlorella is a type of green algae that grows in fresh water. It is typically grown in large tanks or ponds and then harvested and processed. The processing usually involves drying and sometimes breaking down the cell walls to make its nutrients more available.

Chlorella is often added to foods as a source of nutrients, particularly protein, vitamins, and minerals. It is also used for its vibrant green color. You can find it in products like smoothies, juices, energy bars, and plant-based protein powders.

In the U.S., chlorella is generally recognized as safe (GRAS) when used as a food ingredient. It is a source of various nutrients. International bodies like the European Food Safety Authority (EFSA) have evaluated algae and their components, but specific evaluations for chlorella's use as a food additive may vary. Some research suggests it may have antioxidant properties and support immune function, but more studies are needed to confirm these effects at typical dietary intakes.
