Probiotics, live microorganisms such as bacteria and yeast, may help prevent and treat some health conditions, especially gastrointestinal disorders. While research suggests probiotics offer little to no benefit for most people at risk of or affected by conditions like Crohn’s disease and ulcerative colitis, they may help children with diarrheal diseases.
Do Probiotics Strengthen the Immune System?
Probiotics are live microorganisms similar to those found in the human body. They are often consumed to benefit digestion and immune function. While not all over-the-counter probiotics have proven benefits for otherwise healthy individuals, research indicates some probiotics can help manage specific conditions.
How Do Probiotics Work?
The human microbiota consists of microorganisms that benefit humans by providing traits they would not otherwise possess. Some microorganisms in the gut assist with food breakdown or prevent colonization by harmful bacteria in exchange for nutrients from ingested food. Probiotics add to this existing gut flora.
What Types of Probiotics Are Available?
The most common probiotics include lactic-acid bacteria strains of Lactobacillus and Streptococcus, which are normal components of the human microbiome used in yogurt, cheese, and some pickled foods. Other probiotics include certain Bifidobacterium bacteria strains and the yeast Saccharomyces boulardii. These microorganisms are available as capsules, powders, liquids, or chewable tablets, and they also occur naturally in certain foods.
What Are the Benefits of Probiotics?
Studies suggest that S. boulardii may reduce the frequency of diarrheal episodes in children with acute diarrhea. Certain probiotic strains, such as L. rhamnosus GG, may modestly reduce the duration of infectious diarrhea. L. rhamnosus GG and S. boulardii may also effectively prevent antibiotic-associated diarrhea in children and adults.
Are There Risks With Taking Probiotics?
Probiotics are generally considered safe; however, they have been associated with bacteremia (bacterial infection of the blood) and fungemia (fungal infection of the blood) in patients with compromised immune systems. Probiotic-associated bacteremia has been reported in individuals with severe ulcerative colitis. While probiotics have proven beneficial for preterm infants by reducing the likelihood of necrotizing enterocolitis, cases of probiotic-associated sepsis have been documented.

Can probiotics replace antibiotics?
Probiotics cannot replace antibiotics. Antibiotics kill or inhibit the reproduction of pathogenic bacteria, and, in the process, they cause dramatic changes in normal human microbial communities. Probiotics can help restore populations of beneficial gut microbiota after antibiotic use, but they do not have the same broad-spectrum antibacterial properties as antibiotics.
What foods are natural probiotics?
Many foods naturally contain probiotics, including yogurt, cheese, and some pickled foods. These foods contain live microorganisms, such as Lactobacillus and Streptococcus strains, which contribute to the diversity and health of the gut microbiome. Consuming these foods can introduce beneficial bacteria into the digestive system.
How do I know if my probiotic is working?
It can be challenging to determine if a probiotic is working, as the effects can vary depending on the individual and the specific probiotic strain. Some people may experience improved digestion, reduced bloating, or more regular bowel movements. If you are taking probiotics for a specific condition, monitor your symptoms to see if they improve over time.
In conclusion, probiotics may offer some benefits for specific conditions, particularly those related to gastrointestinal health. However, their effectiveness can vary, and they may not be suitable for everyone.
