Yerba mate (sometime labeled as mate, or Ilex paraguariensis) is a South American shrub of the holly family. It is commonly used to create a “tea like” infusion called “maté.” A potent antioxidant, it is also a rich source of xanthines (caffeine, theobromine, and theophylline) and chlorogenic acid-the most likely reason for its inclusion in many popular weight loss products. See the full review for complete details.

Glucomannan (”konjac” or “amorphophallus konjac”) is an un-absorbable polysaccharide that is derived from the konjac root (i.e., a “fiber” supplement).
