Royal Green maca is certified organic maca,it is hand selected on size and colour (black, purple & yellow). Royal Green use 80% black, 15% purple & 5% yellow maca roots. This provides the widest profile of active nutrients possible, offering a maximum effect. Royal Green maca is concentrated under a maximum temperature of 45 degrees Celcius. While maca is a well-known plant, not many people have discovered its whole potential. The reason is that most products that are available, are light yellowish, sweet smelling maca powders. These are usually not certified organic, are extracted using high temperatures and contain fillers (corn & rice powder) and sometimes even maltodextrin or sugar. Royal Green delivers a ‘raw’, highly concentrated (6:1) & 100% certified organic maca. Produced at low temperature, not irradiated and free of fillers. The capsules are 100% Vegan and naturally gluten free.
