Zantrex-3® is a dietary supplement that promises to burn fat, increase energy, and promote weight loss. Zantrex-3® includes nutrients derived from herbs and botanicals that may help promote weight loss and enhance thermogenesis (calorie expenditure). The supplement contains niacin, yerba mate, caffeine, guarana, damiana, schizonepeta, green tea, piper nigum (black pepper extract), panax and tibetan ginseng root, maca root, cocoa nut, kola nut and thea sinensis complex.
The manufacturer, Zoller Labs, has not conducted clinical studies of Zantrex-3®. However, research suggests that the caffeine found in yerba mate, green tea, guarana, cocoa nut and kola nut may increase the metabolic rate, produce a thermogenic effect, and promote weight loss. Green tea and yerba mate may have additional weight loss benefits. Ginseng is used to increase energy, restore vitality and enhance resistance to stress. Maca root, ginseng and damiana are often used as aphrodisiacs. Piper nigum may enhance the absorption of supplements in the body.
Large amounts of caffeine have been shown to produce a stimulant effect by increasing energy and the metabolism. However, large doses of caffeine are also associated with adverse effects including nervousness, anxiety, insomnia, and irritability.
"Zantrex-3 is a revolutionary, powerful compound intended for otherwise healthy people who need to lose 10-15 pounds, who want extreme energy, and who have no medical problems," states the manufacturer, on its website. "People who have hypertension, high blood pressure, diabetes, heart trouble, or who are sensitive to stimulants should not take Zantrex-3. Consult your health-care professional."
