Royal Green gives you the following guarantees: 100% certified organic Maca. 100% raw. Highly concentrated (6:1). 80% black, 15% purple & 5% yellow Maca. 100% free of fillers. Gelatinized for optimal digestion and absorption. 100% vegetarian & vegan. Naturally gluten free. Maca (Lepidium Meyenii Walp) is a small root that grows in the Andes of Peru at 4300 meter altitude where no other plants can grow due to the difficult climate! After allowing our Maca to grow for 8 months, the Royal Green Maca is harvested. After the harvest the Royal Green certified organic Maca is dried and hand selected on size and colour (black, purple & yellow). The full process is done under monitored organic criteria and that is why Royal Green Maca is certified organic.
