Our Black Maca Extract is made from our certified organic Peruvian grown Black Maca root Powder traditionally grown and harvested on an organic farming co-op in a remote pristine part of the Peruvian Andes It is never heated above 106 degrees F in order to preserve nutrients at maximum levels. Scientific research has found Black Maca to have some important properties among all Maca colors. A 2009 study in Peru found Black Maca to be the best for increasing sperm count and motility as well as for boosting male libido. A Swiss study from 2010 showed Black Maca to excel at protecting bone structure and preventing osteoporosis. 2 studies from China in 2006 and 2011 found Black Maca to be superior for increasing memory, concentration and learning. And a UK study from 2011 found that Black Maca supported muscle growth. We generally recommend Black Maca for men looking to increase libido and performance, for students looking to boost mental sharpness and for anyone working to increase muscle size or athletic performance.
