Zynamite® (Mangifera indica) is a multi-award winning, patented botanical extract that gives active people and athletes more than just caffeine. It comes from the leaves of cultivated mango trees. These leaves are a by-product of mango production, which also makes Zynamite® a sustainable ingredient. It provides a significant and long-lasting energy boost, both mentally and physically and… it has no side effects: no increased heart rate, no agitated feeling or ups and downs.
