Gelatinized Yellow Maca is made from Yellow Maca roots, which make up about 60% off the annual harvest in Peru. These roots are pre-cooked to remove starch content and ease digestion. It takes about 4 kg of Raw Maca roots to produce 1 Kg of Gelatinized Maca powder, making it more concentrated than Raw Maca products. To date hundreds of studies, all available publicly in the Pubmed database, have found Yellow Maca to be useful for energy building, fertily, hormone balance, mental focus and more. Yellow Maca is indeed a nutritional powerhouse, containing nearly all essential amino acids and free fatty acids, significant levels of vitamins A, B1, B2, B3, and C, minerals iron, magnesium, zinc and calcium, a high concentration of bio-available protein and nutrients unique to Maca called macaenes and macamides. Maca is also an "adaptogen," or rare form of plant that is thought to raise the overall life force energy of those who consume it.
