Supplements are a simple way to get large amounts of healthy microbes into the body. However, it is important that people follow the instructions and take the correct dosage.
Probiotics may have several benefits due to how they interact with the body. While they may affect many systems and organs, the main advantages of probiotic use focus on aiding gut flora and digestive health. A study in Medicine notes that they may play a role in several digestive issues, such as:.
However, the study researchers call for more long-term research into chronic digestive conditions, as there is limited evidence to make any claims about probiotic use. A review notes the benefits of taking probiotics :. It is important to note that these effects persist for as long as the person takes probiotics.
Also, there is limited evidence discussing the long-term benefits, so more research is necessary. Probiotics are generally safe. However, taking them in large doses may cause minor symptoms in some people, such as gas or bloating. There are some rare side effects associated with probiotics, generally where the person has underlying issues.
People who are critically ill or have conditions that compromise their immune system should not take probiotics. Additionally, the potential risks of probiotic use in pregnant or breastfeeding people are not well-understood. Click here to learn more about the potential side effects of probiotics. Probiotics are live microbes that may positively influence the body. They may help improve markers of digestive health, reduce symptoms of some digestive conditions, and improve the immune system.
For short-term symptom relief, such as reducing diarrhea, some probiotics may work in as little as a few days. For chronic conditions or general immune health, it may be most beneficial to take probiotics for weeks or months at a time. Most people can tolerate probiotics well, and they can help restore or balance the healthy gut microbiome.
However, some may wish to discuss probiotics with their doctor before they incorporate them into their diet. Probiotics are a type of bacteria that may benefit health. Here, learn which illnesses probiotics may benefit and which sources may be most effective. Taking probiotics can help restore the natural balance of bacteria in the gut and may help treat a number of health issues. Some people experience…. Can probiotics be harmful? Probiotics have an extensive history of apparently safe use, particularly in healthy people.
The risk of harmful effects from probiotics is greater in people with severe illnesses or compromised immune systems. When probiotics are being considered for high-risk individuals, such as premature infants or seriously ill hospital patients, the potential risks of probiotics should be carefully weighed against their benefits.
Possible harmful effects of probiotics include infections, production of harmful substances by the probiotic microorganisms, and transfer of antibiotic resistance genes from probiotic microorganisms to other microorganisms in the digestive tract. Some probiotic products have been reported to contain microorganisms other than those listed on the label.
In some instances, these contaminants may pose serious health risks. In addition to the previously mentioned studies on diet-microbiome interactions in the digestive tract, recent topics include: The mechanisms by which probiotics may help to reduce postmenopausal bone loss Engineering probiotics to synthesize natural substances for microbiome-brain research The mechanisms by which certain probiotics may relieve chronic pelvic pain The effects of a specific Bifidobacterium strain on changes in short-chain fatty acid production in the gut that may play a role in antibiotic-associated diarrhea.
This is especially important if you have health problems. Anyone with a serious underlying health condition should be monitored closely while taking probiotics. Take charge of your health—talk with your health care providers about any complementary health approaches you use.

Science has made tremendous strides in the past two decades toward understanding the roles that probiotics play in human health and disease. Despite widespread studies, researchers are still working on identifying all the individual microbial species that live in your gut.
Identifying them is crucial to understanding how they function in human health. For example, researchers in reported identifying nearly 2, previously unknown gut bacterial species. This was a major step toward categorizing the microbes living in the human gut After identifying the microorganisms, the next challenge facing researchers is to associate the various species, subspecies, and strains of microbes with their effects on human health — and this is where things get tricky Though thousands of studies have assessed the health benefits of probiotics for many clinical conditions, the results often contradict each other 79 , One reason for this is that methods for processing and analyzing probiotics data are not consistent around the world.
This leads to conflicting research analyses of published data The standardization of probiotics research is challenging because the human body contains a large and diverse set of microorganisms, which varies among countries — and even among individuals in the same country. Plus, the bacterial strains themselves are constantly evolving, as are the health and environments of their human hosts. Probiotics researchers face the task of classifying what might be trillions of ever-changing organisms in varied and evolving environments.
Scientists must standardize a mountain of sometimes conflicting evidence from thousands of studies, and then translate that evidence into clear recommendations for therapeutic probiotic use Researchers are challenged with identifying all the microbiota in the vast and changing microbiome of the human gut.
They also need to establish a system for standardizing research results to develop clear therapeutic recommendations for probiotic uses. Maintaining a healthy gut is about more than taking a probiotic supplement. Day-to-day diet and exercise are just as important, as many lifestyle factors affect your gut bacteria.
