The timeline of benefits from probiotics varies, and it depends largely on the probiotic blend and what the probiotic is being taken for. Underlying health conditions can contribute to how quickly and to what extent someone notices improvement as well.
While some positive changes may be noted within the first month, it’s generally encouraged to continue using for additional benefits for 8 to 12 weeks. Findings from a 2018 study suggest that high probiotic intake for 12 weeks could lead to fewer upper respiratory infections.
Probiotics are not immediate in their ability to recolonize or repopulate bacteria within an organ, and it often takes some time to develop a healthy microbiome in that space. Consumers should expect that these processes should take weeks before there’s any measure in change.
If you have a health condition or concern, it’s best to talk with your doctor before adding any supplement product to your routine – including probiotics and “all-natural” products.
