Overview

Chlorella is a type of green algae (Chlorella vulgaris) that is considered one of the most nutrient-dense foods on the planet. It is exceptionally rich in chlorophyll, protein (up to 60% by dry weight), vitamins, minerals, and antioxidants. Chlorella has a unique cell wall that is believed to bind to heavy metals and toxins, making it popular for detoxification support.

Unlike Spirulina (a blue-green algae), Chlorella is a true green algae with a higher chlorophyll content. It is available in powder, tablet, and capsule forms. Chlorella is particularly valued for its potential to support detoxification, immune function, and overall nutrition.

Potential Benefits

Chlorella has been studied for its detoxification, immune-modulating, and nutritional properties.
