Fructooligosaccharide is not a drug, but it can be used as intestinal health food, but it is not recommended to take it for a long time. If you want to take it for a long time, it is recommended to take stachyose. Stachyose is extracted from the natural plant Diligen through water as a medium, which is very suitable for long-term use. Moreover, it is suitable for all ages, and can be taken safely from newborns to the very old. If you choose, you can consider the stachyose series products produced by Xi An Dapeng, which is the only stachyose brand selected by China Aerospace.
