We also know that microbiomes vary widely in healthy people, Probiotics for gut health. In the Human Probiotics for gut health Project, stool samples from thousands of healthy people those without abdominal pain, diarrhea, constipation, or other known gut problems were examined.
There was a wide range of gut bacteria, meaning that two people could have totally different gut bacteria yet both people are perfectly healthy. There is scientific evidence that probiotics help for certain health issues. But not all probiotics are right for all illnesses and diseases. Some probiotic manufacturers make big claims that are not backed up by any evidence.
The degree to which a probiotic can correct any issue is probably limited. The American Gastroenterological Association recommends use of probiotics in three specific situations: 1 to prevent gut infections while taking antibiotics, 2 in preterm infants, and 3 in people with inflammatory bowel disease who have a condition called pouchitis.
Most people who take probiotics do not fall into any of these three categories. I try to steer my patients away from probiotics for the purpose of improving overall health and toward a fiber-based diet.
The organisms recommended by the American Gastroenterological Association are S. boulardii a yeastLactobacillus species, and Bifidobacterium species.
Again, these are recommended only in a few specific situations and not for overall health. Further, probiotics have different effects in different people. Remember that probiotics are regulated like food, not drugs. Probiotic manufacturers are not obligated to prove any health benefits of their products.
Probably not. No studies have ever shown that probiotics reduce abdominal pain. In the office, I encourage people to think about a healthy fiber-rich diet instead of probiotics. Dietary fiber is a prebiotic—it changes which bacteria are present in the gut.
Fiber is inexpensive and natural, and by changing your dietary fiber intake you are changing your gut bacteria.

Probiotics for gut health -
When the gut becomes unbalanced with unhealthy levels of certain bacteria, probiotics can help restore the balance. They've been shown to secrete protective substances, which may turn on the immune system and prevent pathogens from taking hold and creating major disease. But we are still learning to understand how probiotics may promote health.
Some studies that suggest if you take a probiotic while taking antibiotics, you're less likely to get diarrhea caused by the antibiotic.
Probiotics may also reduce the number of colds you'll have in a year. Probiotics are commonly used to reduce gastrointestinal symptoms that are not due to acute illness, such as gas, bloating, and constipation. But we need more studies to determine who will get symptom improvement, particularly in older people.
Many types of probiotics are on the market. Some have been well studied, and some haven't. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. VIEW ALL HISTORY.

A comparison of the best probiotic supplements. What are probiotics? Having the right gut bacteria has been linked to numerous health benefits, including the following 4 , 5 :.
Probiotics are living microorganisms that, when ingested, provide a health benefit 6. However, the scientific community often disagrees on what the benefits are, as well as which strains of bacteria are responsible 7. Probiotics are usually bacteria, but certain types of yeasts can also function as probiotics.
There are also other microorganisms in the gut that are being studied, including viruses, fungi, archaea, and helminths 8.
You can get probiotics from supplements, as well as from foods prepared by bacterial fermentation. Probiotic foods include yogurt, kefir, sauerkraut, tempeh, and kimchi. Probiotics should not be confused with prebiotics, which are carbs — often dietary fibers — that help feed the friendly bacteria already in your gut 9.
Products that contain both prebiotics and probiotics are referred to as synbiotics. Synbiotic products usually combine friendly bacteria along with some food for the bacteria to eat the prebiotics , all in one supplement The most common probiotic bacteria are Lactobacillus and Bifidobacteria. Other common kinds are Saccharomyces, Streptococcus, Enterococcus, Escherichia, and Bacillus.
Each genus comprises different species, and each species has many strains. Different probiotics have been found to address different health conditions.
Therefore, choosing the right type — or types — of probiotics is essential. Some supplements, known as broad-spectrum probiotics or multi-probiotics, combine different species in the same product.
Although the evidence is promising, more research is needed on the health benefits of probiotics. Probiotics are living microorganisms that boost health when consumed in adequate amounts.
There are many different types, and you can obtain them from foods or supplements. The complex community of microorganisms in your gut is called the gut flora, gut microbiota, or gut microbiome 14 , The gut microbiota includes bacteria, viruses, fungi, archaea, and helminths — with bacteria comprising the vast majority.
Your gut is home to a complex eco-system of — bacterial species Most of the gut flora is found in your colon, or large intestine, which is the last part of your digestive tract. Surprisingly, the metabolic activities of your gut flora resemble those of an organ.
Your gut flora performs many important health functions. It manufactures vitamins, including vitamin K and some of the B vitamins It also turns fibers into short-chain fats like butyrate, propionate, and acetate, which feed your gut wall and perform many metabolic functions 19 , These fats also stimulate your immune system and strengthen your gut wall.
This can help prevent unwanted substances from entering your body and provoking an immune response 21 , Your gut flora is highly sensitive to your diet, and studies show that an unbalanced gut flora is linked to numerous diseases 23 , Your gut flora consists of hundreds of types of microorganisms.
These microorganisms perform numerous important bodily functions. Probiotics are widely researched for their effects on digestive health Evidence suggests that probiotic supplements can help cure antibiotic-associated diarrhea When people take antibiotics , especially for long periods of time, they often experience diarrhea — even long after the infection has been eradicated.
This is because the antibiotics kill many of the natural bacteria in your gut, which shifts the gut balance and allows harmful bacteria to thrive. Probiotics may also help combat irritable bowel syndrome IBS , a common digestive disorder, reducing gas, bloating , constipation, diarrhea, and other symptoms.
Research regarding the effectiveness of probiotics supplementation for the treatment of IBS is mixed. A recent review reported that seven of the studies indicated IBS improvement with probiotic supplementation, but four did not Research indicates that multi-strain probiotic supplements seem to bring most IBS improvement, especially when taken for longer than 8 weeks.
However, much remains unknown about probiotic treatment for IBS. Questions like the following have yet to be answered 33 :. Researchers find early results of IBS probiotic treatment promising but say additional large trials are necessary before healthcare providers can confidently prescribe probiotic treatments consistently for IBS Again, researchers say further research is needed before the treatment is confirmed to be effective Probiotics may also help fight Helicobacter pylori infections, which are one of the main drivers of ulcers and stomach cancer 36 , 37 , However, be sure to consult your healthcare provider first.
Probiotics may be effective against various digestive problems, including antibiotic-associated diarrhea and IBS.
Some research indicates that people with obesity have different gut bacteria than those who are lean Research shows a connection between gut microbes and obesity in both infants and adults.
It also shows that microbial changes in the gut are a factor in developing obesity as an adult Therefore, many scientists believe that your gut bacteria are important in determining body weight 41 , While more research is needed, some probiotic strains appear to aid weight loss Nevertheless, researchers advise caution in rushing to this conclusion, noting that there are still many unknowns.
These unknowns include 44 :.

Probiotics are among the most popular dietary supplements and sales of them continue to skyrocket each year.Probiotics for gut health -
These units represent the number of viable bacteria per dose. Most supplements contain 1—10 billion CFUs per dose, but some contain much larger amounts. For beneficial effects, probiotics must be taken in quite large doses. Researchers suggest that probiotics must contain at least 10 6 1 million viable CFUs per gram to be able to survive digestion and exert positive effects in the body.
Our opinions are ours alone and have not been reviewed, approved, or otherwise endorsed by the brands. Note that the dosage recommendations vary between 1 and 2 capsules or tablets, taken 1—2 times daily. Thus, a product that you need to take fewer times per day may be comparatively cheaper despite having a higher price per count than a product you need to take multiple times per day.
Probiotics are found naturally in certain foods , such as kimchi and fermented yogurt. They are also found in your gut, where they participate in a variety of important bodily processes , such as vitamin production, mood regulation, digestion, and immune function. Probiotics are also available in supplement form.
These supplements contain high doses of either a single probiotic strain or multiple probiotic strains. Probiotic supplements have been linked to some health benefits. But while research on probiotics has increased significantly over the past 20 years, researchers are still learning about them and their health effects.
Also keep in mind that because probiotics are quite vulnerable to factors such as temperature change and storage time, many may no longer be viable by the time you purchase them.
This indicates that a product contains a therapeutic number of CFUs after the product is purchased. Contrary to popular belief, probiotic supplements are not necessary or appropriate for most people. Plus, probiotic supplements could lead to excessive immune stimulation and infection among people with weakened immune systems.
While some people, including those with IBS and certain types of inflammatory bowel disease IBD , may benefit from specific strains of probiotics, in general, most healthy people who follow a nutritious diet and healthy lifestyle do not need to take probiotic supplements.
They can help you decide whether a probiotic supplement is appropriate and give brand and dosage recommendations. Research suggests that probiotics must contain at least 10 6 1 million viable CFUs per gram to have a clinically significant effect.
Additionally, the most-studied and most-used strains of probiotics are Lactobacillus and Bifidobacterium. However, probiotic supplements are strain- and disease-specific, so the most effective strain will depend on the condition or issue that the supplement is meant to improve.
Because probiotics are strain-, disease-, and symptom-specific, no single probiotic is more effective overall than others. Still, some brands are considered to offer higher quality probiotic supplements, including Culturelle, Seed, and Jarrow Formulas.
acidophilus, L. rhamnosus, L. reuteri and Bifidobacterium species. To maximize probiotic benefits, Haque recommends considering high CFUs around 40 billion or more , multiple strains greater than two , and products from reputable manufacturers.
Lastly, Haque highlights the importance of also consuming prebiotic fiber and fermented foods to complement probiotic supplements, though consult your healthcare professional for personalized advice. Probiotic supplements may be helpful for people with certain conditions, such as IBS, constipation, and UTIs.

Eating fermented foods with live probiotics can have powerful benefits for your body and brain. Here is a list of 11 super healthy probiotic foods.
The choice can be difficult. In the United States, probiotics are generally sold as food ingredients, drugs, or dietary supplements. While the Food and Drug Administration FDA regulates each of these in different ways, most foods and supplements do not require approval before marketing Regulations on probiotics vary greatly around the world, so ordering online from other countries is risky.
Unregulated food items, cosmetics, and supplements are easy to find abroad, but their safety is unconfirmed. Looking for companies that follow best practices, such as third-party testing, can help you find high quality supplements.
The best choice is to run your choice by your healthcare provider or ask for suggestions. They may be able to recommend products they know to be safe and effective. In the first few days of taking a probiotic supplement, you may experience side effects related to digestion, such as gas and mild abdominal discomfort In people with compromised immune systems, including those with HIV, AIDS, and several other conditions, probiotics can lead to dangerous infections If you have a medical condition, consult your healthcare provider before taking a probiotic supplement.
Probiotic supplements may cause digestive symptoms, which should subside within a few days. They may also be dangerous for people with certain medical conditions.
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. However, probiotic supplements may offer a wide range of benefits with few side effects. If so, you might want to consult the World Gastroenterology Organization Global Guidelines.
It lists probiotics, conditions, and recommended dosages. Caution is always advised when starting with probiotics. Be sure to use a reputable product, start slowly, and get good advice from a trusted healthcare practitioner.

What are probiotics? If any of the pouches become inflamed, the condition is called diverticulitis. Patients with diverticulitis can have severe abdominal pain and may develop serious complications. A review of 11 studies participants of probiotics for diverticular disease was unable to reach conclusions on whether the probiotics were helpful because of the poor quality of the studies.
Inflammatory Bowel Disease. Symptoms may include abdominal pain, diarrhea which may be bloody , loss of appetite, weight loss, and fever. The symptoms can range from mild to severe, and they may come and go.
Treatment includes medicines and in some cases, surgery. A review of 21 studies in patients with ulcerative colitis 1, participants indicated that adding probiotics, prebiotics, or synbiotics to conventional treatment could be helpful in inducing or maintaining remission of the disease.
Irritable Bowel Syndrome. A review of 53 studies 5, total participants of probiotics for irritable bowel syndrome IBS concluded that probiotics may have beneficial effects on global IBS symptoms and abdominal pain, but it was not possible to draw definite conclusions about their effectiveness or to identify which species, strains, or combinations of probiotics are most likely to be helpful.
Also, some studies had weaknesses in their design. Conditions in Infants. Infant Colic. Colic is excessive, unexplained crying in young infants. Babies with colic may cry for 3 hours a day or more, but they eat well and grow normally. A review of 7 studies participants of probiotics for colic, 5 of which involved the probiotic Lactobacillus reuteri DSM , found that this probiotic was associated with successful treatment defined as a reduction of more than half in daily crying time.
However, the effect was mainly seen in exclusively breastfed infants. No harmful effects were seen in a review of 4 studies participants of L. Necrotizing Enterocolitis.
Necrotizing enterocolitis is a serious, sometimes fatal disease that occurs in premature infants. It involves injury or damage to the intestinal tract, causing death of intestinal tissue. A review of 23 studies 7, infants showed that probiotics helped to prevent necrotizing enterocolitis in very-low-birth-weight infants.
However, the results of individual studies varied; not all showed a benefit. Probiotics that included both Lactobacillus and Bifidobacterium seemed to produce the best results, but it was not possible to identify the most beneficial strains within these large groups of bacteria.
None of the infants in the studies described above developed harmful short-term side effects from the probiotics. However, the long-term effects of receiving probiotics at such a young age are uncertain.
Outside of these studies, there have been instances when probiotics did have harmful effects in newborns. In , the FDA warned health care providers that premature infants who are given probiotics are at risk of severe, potentially fatal infections caused by the microorganisms in the products.
Sepsis in Infants. Sepsis is a serious illness in which the body has a harmful, overwhelming response to an infection.
It can cause major organs and body systems to stop working properly and can be life threatening. The risk of sepsis is highest in infants, children, the elderly, and people with serious medical problems. One group particularly at risk for sepsis is premature infants. A review of 37 studies 9, participants found that probiotics were helpful in reducing the risk of sepsis in premature infants.
Dental Disorders. Dental Caries Tooth Decay. A small amount of research, all in infants and young children, has examined the possibility that probiotics might be helpful in preventing dental caries also called cavities or tooth decay.
A review of 7 studies 1, total participants found that the use of probiotics was associated with fewer cavities in 4 of the 7 studies, but the quality of the evidence was low, and no definite conclusions about the effectiveness of probiotics could be reached.
Periodontal Diseases Gum Disease. Periodontal diseases result from infections and inflammation of the gums and bone that surround and support the teeth. If the disease is severe, the gums can pull away from the teeth, bone can be lost, and teeth may loosen or fall out.
A review of 12 studies participants that evaluated probiotics for periodontal disease found evidence that they could be a helpful addition to treatment by reducing disease-causing bacteria and improving clinical signs of the disease.
However, effects may differ for different probiotics. Conditions Related to Allergy. Allergic Rhinitis Hay Fever. A review of 23 studies 1, participants in which probiotics were tested for treating allergic rhinitis found some evidence that they may be helpful for improving symptoms and quality of life.
However, because the studies tested different probiotics and measured different effects, no recommendations about the use of probiotics could be made. Few side effects of probiotics were reported in these studies. A review of 11 studies participants of probiotics for asthma in children had inconclusive results.
Atopic Dermatitis. Many people outgrow it by early adulthood. Atopic dermatitis is one of several types of eczema. A review of 13 studies 1, participants of probiotics for the treatment of atopic dermatitis in infants and children did not find consistent evidence of a beneficial effect.
A review of 9 studies participants in adults provided preliminary evidence that some strains of probiotics might be beneficial for symptoms of atopic dermatitis.
Prevention of Allergies. A review of 17 studies 4, participants that evaluated the use of probiotics during pregnancy or early infancy found that infants exposed to probiotics had a lower risk of developing atopic dermatitis, especially if they were exposed to a mixture of probiotics.
However, probiotics did not have an effect on the risks of asthma, wheezing, or hay fever allergic rhinitis. Other Conditions. Research has identified mechanisms by which probiotics, either taken orally or used topically applied to the skin , might influence acne. Hepatic Encephalopathy.
When the liver is damaged and unable to remove toxic substances from the blood, the toxins can build up in the bloodstream and affect the nervous system. This may lead to impairments of brain function called hepatic encephalopathy.
A review looked at 21 studies 1, participants of probiotics for hepatic encephalopathy and concluded that they were generally of low quality. There was evidence that compared with a placebo an inactive substance or no treatment, probiotics probably had beneficial effects on hepatic encephalopathy, but it was uncertain whether probiotics were better than lactulose, a conventional treatment for liver disease.
Upper Respiratory Infections. Probiotics have been tested for their effects against upper respiratory infections a group that includes the common cold, middle ear infections, sinusitis, and various throat infections.
A evaluation of 12 studies with 3, total participants indicated that people taking probiotics may have fewer and shorter upper respiratory infections. However, the quality of the evidence was low because some of the studies were poorly conducted.
Urinary Tract Infections. A review of 9 studies participants of probiotics for the prevention of urinary tract infection did not find evidence of a beneficial effect.
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. NCCIH-Funded Research NCCIH sponsors a variety of research projects related to probiotics or the microbiome. 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.
