Can Roy's Bacillus lactis DSM 17648 work in seclusion? Door? Screw? Bacteria? Have you ever used Yuan Yi Sheng? Quiet?

I was recommended to buy a friend of Yuansheng Yiyou to teach me this Lactobacillus Roy before, but I don't remember much, only I remember doing a lot of clinical work. Many countries have many patents. I bought two or three boxes in the back, mainly to eat with my tetralogy medicine. In short, the result is good. I don't know whether quadruple drugs are better or probiotics. It doesn't matter.
