I just found this article from the U.K. which found lactobacillus probiotics and inulin a chicory product helped people with long Covid and helped some of them get rid of their long term gut issues.
The article caught my husbands eye as he has been adding inulin and Kefir to his diet to help with gut issues caused by PD.
Any idea where we can view the actual studies so we can confirm exactly what was given as well as the dosage involved?
I m really sorry I don’t but I ll have a search around later today to see if it’s been published. Inulin comes in a bulk powder and has recommendations on its instructions about how much to take.
I think this information is linked to that study I haven’t had time to read it all.
