How Long Do Probiotics Stay in Your System?

Published February 14, 2023
Probiotics are microorganisms that, when ingested, provide health benefits, but how long do probiotics stay in your system? These probiotics are beneficial microorganisms that support the body’s health and proper functioning. Although bacteria are the most common kind of probiotics, yeasts can also fulfill this function.
How Long Do Probiotics Stay in Your System?
The effects of probiotics subside within one to three weeks of discontinuing usage. This is why it is important to take probiotics on a regular basis. Your immune system allows a variety of bacteria to exist in your digestive system. The duration of the probiotic’s effects after a single dose is also dependent on the strain. Bacterias like Lactobacillus and Bifidobacterium can survive in your digestive tract for a longer period of time than most others.
If you want significant results, you should check into prebiotics because probiotics are foreign microorganisms that are introduced into the gut; they are prone to dying upon entry or being eradicated by the immune system.
However, prebiotics does not introduce new bacteria into the body. Instead, you consume a complex of fibers that can withstand your digestion process and reach your gut. After reaching your stomach, it nourishes and fortifies the healthy bacteria already present in your gut, making them more effective at maintaining your gut health.
How Long Do Probiotics Last in the Gut?
The amount of time probiotics remain in your gut depends on numerous factors, such as:
- Choices in diet and lifestyle
- How often it’s taken
- The type of strain
- Antibiotics and other drugs
- How much was taken
The majority of probiotics are temporary, meaning that they travel through the gut completing their job without attaching to the wall lining of the gut; this is why it is so important to take probiotics daily — to give your gut a consistent supply. Unfortunately, this also suggests that the effects you enjoy while taking the probiotics are likely to wane if you stop taking them.

Are there Long-Term Effects of Taking Probiotics?
Long-term probiotic consumption is safe and beneficial to the gut microbiome. However, the period of probiotic intake varies according to the strains of bacteria and product. Therefore, when choosing a probiotic to include in your daily diet, look for a supplement that contains multiple strains and species backed by scientific and clinical evidence.
Take a break from probiotics if you have persistent adverse effects, such as bloating and gas, and be sure you take the right strain and amount. Before beginning a probiotic supplement, you should consult with your healthcare provider to determine the best strain, right dose, and proper duration for your health needs and goals.
Keeping Your Body Healthy
A person’s body composition, how often they take probiotics, how much they take, and what kind of probiotic they take all have a role in determining how long do probiotics stay in your system. In general, most probiotics will be cleared from your system in one to three weeks.
However, if you want prolonged benefits from probiotics, it’s best to cycle them often so that your gut bacteria can adjust and continue to thrive.
