Zhuangling Water Su糖 is a micro-ecological preparation extracted from plants using water extraction technology, one of the bifidus factors. Zhuangling Water Su糖 has a very significant proliferation effect on beneficial flora such as bifidobacteria and lactic acid bacteria in the human gastrointestinal tract, and can quickly improve the internal environment of the human digestive tract and regulate the micro-ecological balance. By obtaining a large amount of proliferated bifidobacteria and lactic acid bacteria, it promotes the formation of a dominant position for beneficial bacteria within the digestive tract, and controls the production of putrefactive bacteria such as gas-producing and acid-producing Clostridium.
