Zantrex Black is the latest in the Zantrex family of weight loss supplements. Zantrex Black is aimed at people who are looking for rapid weight loss. Zantrex Black uses a variety of ingredients to promote weight loss through a combination of appetite suppression and metabolism boosting. Several of those ingredients, including yerba mate, black tea and trimethlxanthine, contain caffeine. Caffiene has been shown to speed up metabolism, improve mental clarity, and increase energy levels, but it may also cause jitteriness, rapid heart rate and sleeplessness. Anyone who is sensitive to caffeine, or who has had problems with it in the past, should probably avoid taking Zantrex Black. Other ingredients in Zantrex Black may aid in weight loss, but little research has been done to verify these claims.
