Chlorella and Spirulina, both renowned for their nutritional prowess, are microalgae that offer a plethora of health benefits rooted in their dense concentration of vitamins, minerals, and proteins.

Let's delve into the specifics of these freshwater and saltwater superfoods to understand how they stand apart and what makes them valuable additions to a balanced diet.

Definition and types of Chlorella and Spirulina

Chlorella is a type of green freshwater algae. It's small and shaped like a ball. This algae is known for having lots of chlorophyll, which gives plants their green color and helps them use sunlight to make food.

There are many kinds of chlorella, but the most common one used for health is called Chlorella vulgaris.

Spirulina is different from chlorella; it's a blue-green algae that grows in both fresh and salt water. Its scientific name is Arthrospira, but we call it spirulina as well. Spirulina has long, spiral-shaped cells and it's famous for its nutrition power.

People add this superfood to things like smoothies and bars because it’s packed with good stuff our bodies need.
