How Quickly Does Probiotics Work?

Probiotics are so popular that global market sales for probiotics have reached over $40 billion and are only expected to grow. The research on probiotics has grown exponentially over the past decade. The more we learn about them, the more we realize that we have a lot more to learnAccording to a published study, at least 3.9 million people in the US alone take probiotic supplements regularly.  


Probiotics are live cultures of microbes similar to the ones found in the body. Just like those found in the body, these microbes have many health benefits. They may help build and restore healthy bacteria in the gut and promote digestive health. They can boost the immune system, keep the skin healthy, and a lot more. Have you ever wondered how long does it take for probiotics to work? Have you ever wondered how long you need to take them? 


Factors that affect how quickly probiotics work 


There is no one-size-fits-all answer for how long does it take for probiotics to work or how long you need to take them. Several factors come into play, such as the following: 

  • the state of your health 
  • your age 
  • your unique gene makeup 
  • why you are taking the probiotics 
  • the strains you are taking 
  • the bacteria you already have in your body 
  • the number of colony-forming units 
  • the product formulation 
  • the product quality 

Results also vary from person to person. Even if you don’t see any changes right away, probiotics may actually do their jobs without you knowing. Below are some factors that can delay the result: 

  • Poor diet 
  • A very unhealthy gut 
  • Frequent use of antibiotics 
  • Chronic stress 
  • Incorrect dosage (too few CFU)Doses vary by brand. Doses higher than 5 billion are more effective than lower doses.  
  • Poor quality. Probiotics are fragile in nature. They must survive the manufacture and storage process. Most of all, they must survive the acidic environment of the stomach.  
  • Improper storageHeat, humidity, and light can affect the quality of probiotics.  
  • You’re not taking it correctly. Read and follow the instruction on the label.  
  • Taking the wrong probiotic strains. Not all strains work for every symptom. Take probiotic supplements that are right for your needs.  


Full timeline 


Taking all the research together, the consensus is that probiotics begins to works from a few days to several weeks. The following list does not include all conditions that probiotics can help, but you can get an idea of what to expect in terms of how long does it take for probiotics to work: 


  • Chronic conditions, general immune health, and gut dysbiosis: It can take weeks of continuous used to see the effects; you need to take it for a while to see results 
  • Irritable bowel syndrome: Noticeable benefits takes around 8 weeks of continuous use or more 
  • Upper respiratory infections and flu-like symptoms: Significantly reduced symptoms when you use multi-strain probiotics. 
  • Occasional diarrhea: 2 to 14 days 
  • Weight maintenance: 8 to 12 weeks 
  • Skin problems: 4 weeks to 3 months 
  • Constipation: 7 days to 14 weeks 
  • Bloating: 3 to 4 weeks
