Has anyone had good or bad effects from prebiotics? Prebiotics are supposed to feed good bacteria, especially in this case bifido strains I'm taking bimuno powder https://www.bimuno.com/bimuno-powder To try to improve my sleep. It seems to have but on the second day on it I've woken up feeling worse with worse function. It's always difficult to know if it's a just an unexpected bad day or is being caused by the new powder. Has anyone else experienced this and does it get better or worse? I can't afford to get worse. Does anyone know why it could be making me feel worse when it's supposed to make your gut healthier? I had gut analysis and my bifido bacteria were not growing. Does prebiotic feed had bacteria too? Thanks.
