Chlorella is a natural, green algae which harnesses energy from sunlight to fuel its growth. Chlorella cells have a tough outer wall, which limits the availability of nutrition. Our chlorella is cultivated and harvested in pure, freshwater pools. High-impact jets then break down the cell walls so it can be better absorbed by the body, before it's dried into a naturally nutritious powder. Chlorella is high in Vitamin B12 which contributes to the normal function of the immune system. A 6g serving of Chlorella provides your recommended daily Vitamin B12 needs. It is also high in iron and contributes to normal formation of red blood cells and haemoglobin.
