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.May contain naturally occuring sulphites.Produced in Asia, packed in the UK. Certified Organic by the UK Soil Association and registered by the Vegan Society.
