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
Looks like this question is based on incorrect premises – it is certainly not necessary to take probiotics indefinitely (at least in pill form – see below). Anyone telling you so is either misinformed or has agenda to push. Probiotics are beneficiary in moderation but excessive intake leads to bloating, gas, increased thirst and other side effects (not to mention possible bacterial infection in case your immune system is compromised). Probiotics are most commonly prescribed with anti-biotics to help restore some of the gut bacteria the anti-biotics inadvertently kill.
That being said, it’s good idea to incorporate some natural probiotic sources into your diet – Greek yogurt, sauerkraut, pickles, kimchi and soy sauce are good sources of probiotics. That in and of itself should be enough to help you regulate gut micro-flora. Still, if you think you could benefit from increased intake, I’d strongly suggest consulting a physician first and finding a good product.
