Eli5: If we are to assume that probiotics survive and thrive in our bodies, why is it necessary to take them indefinitely? Shouldn’t we be able to establish a self-sustaining colony?
In: Biology
As other people already said you don’t “need” to take them indefinitely but eating probiotic food is good for your general health ( and tastes good).
When you start eating probiotics or if you eat too much, you might experience bloating, mild diarrhea and other symptoms because you’re altering your gut flora.
If you want those changes to persist ( probiotics establishing colonies in your gut) you need to keep eating probiotics for a long time ( I’ve heard from a month up to a year). Don’t need much but need regularity until you give the colony a chance to establish.
That said, unles prescripted by a professional, probioticscan be harmful if you have internal wounds ( such as an ulcer)
