No, probiotic powders or tablets processed by microencapsulation, freeze-drying and other technologies can be stored at room temperature, and all probiotic products have a shelf life. Pay attention to eating during the shelf life, so as not to make probiotics lose their activity.

The human body can produce probiotics by itself. Edible food will also produce a large number of probiotics after intestinal digestion, decomposition and fermentation. Ordinary people's demand for probiotics is not great. Under normal circumstances, the human body can adjust the balance of flora in the body by itself. For children with normal development, there is absolutely no need to supplement probiotics.

Extended data

Probiotics are mainly used in two situations (short-term use under the guidance of a doctor, not long-term abuse):

1. Long-term use of antibiotics not only kills pathogenic bacteria, but also kills probiotics that coexist with them, so it is necessary to supplement probiotics and re-establish the microecological barrier in the body.

2. Diarrhea leads to the loss of a large number of probiotics, leading to intestinal flora imbalance. At this time, it is necessary to supplement probiotics and re-establish the balance of intestinal flora. Patients with diarrhea caused by intestinal diseases who really need probiotics should take enough medicinal probiotics under the guidance of a doctor to avoid delaying their illness.
