Higher doses of prebiotics or probiotics may be useful under conditions of dysbiosis.

“So these are not high dose probiotics except under conditions of dysbiosis where, for instance, if somebody has done a round of antibiotics and they need to replenish their gut microbiome, there are foods and there are pill form and powder form prebiotics and probiotics that can be very useful. Or in cases where people have been very stressed or are undergoing excessive travel or have shifted their diet radically, maybe that's due to travel, maybe that's due to illness, maybe that's due to stress.”
