A 2019 review concluded that a multi-strain probiotic might improve IBS symptoms. The researchers called for further investigations into whether strains of Akkermansia, Bacteroides, and Faecalibacterium bacteria could play a role in future therapies. After studying data from nearly 2,000 people, the researchers concluded that probiotic supplements could significantly reduce total cholesterol levels in the blood.
Atopic dermatitis, the most common form of eczema, is also one of the most common chronic inflammatory skin disorders, affecting approximately 15% to 20% of children and 1% to 3% of adults worldwide [12]. With three easy-to-follow recipes, the guide makes it easy to create a tasty breakfast, lunch, and dinner full of health-boosting probiotics. However, the effects would likely depend on the type and dosage of probiotic. Below are some ways in which probiotics may help maintain health. Learn more about the difference between prebiotics and probiotics.
A 2017 review concluded that consuming foods containing probiotic Lactobacillus bacteria could reduce levels of low-density lipoprotein, or “bad” cholesterol, as well as total cholesterol. People often consume probiotics in the hope of balancing their intestinal flora, also known as the gut microbiome. There are many strains of probiotic bacteria, but the main ones are of the Lactobacillus or Bifidobacterium groups. A large review of 35 studies found certain strains of probiotics can reduce the duration of diarrhea by an average of 25 hours (9). These include benefits for weight loss, digestive health, immune function and more (2, 3). Probiotics are sold as supplements, which means they’re not regulated by the U.S.
Probiotics have gained significant popularity in recent years for their potential health benefits. These live bacteria and yeasts are often touted as being beneficial for digestion, immunity, and overall gut health. But are probiotics truly as helpful as they are made out to be, or is it all just wishful thinking?
For instance, a review of studies published in the November 2022 Journal of Medical Microbiology found that people who used probiotics in combination with antibiotics reported less diarrhea and other gastrointestinal symptoms. Some studies also note benefits of probiotic supplementation against inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis. Again, researchers say further research is needed before the treatment is confirmed to be effective (35). Diff is a type of bacteria that can infect the digestive system and cause severe diarrhea and other complications.
Probiotics should not be confused with prebiotics, which are carbs — often dietary fibers — that help feed the friendly bacteria already in your gut (9). If you’re ready to add probiotics to your diet, you have a lot of options. Look for them in health food stores, grocery stores, drugstores, and online. Talk to your health care provider before starting a probiotic. People with very weak immune systems, such as those undergoing chemotherapy, should not take probiotics due to risk of infection.
The science is sketchier, though, on which probiotic strains are most helpful, and experts stress that more research is needed. To be safe, stick to a healthy diet and eat a variety of foods every day. Your overall gut health also depends on eating fiber-rich and prebiotic foods, plus limiting certain foods, like red meat and processed foods. Most people can get the probiotics they need by eating fermented foods, so talk with your doctor first before you try supplements.
Species-specific mechanisms can include vitamin synthesis, gut barrier reinforcement, bile salt metabolism, enzymatic activity, and toxin neutralization. Strain-specific mechanisms, which are rare and are used by only a few strains of a given species, include cytokine production, immunomodulation, and effects on the endocrine and nervous systems. Through all of these mechanisms, probiotics might have wide-ranging impacts on human health and disease.
The Potential Benefits of Probiotics
1. Improved Digestion: Probiotics are thought to help restore the natural balance of bacteria in the gut, which can aid in better digestion and nutrient absorption.
2. Enhanced Immunity: Some studies suggest that probiotics may help strengthen the immune system by promoting the growth of good bacteria in the gut.
3. Gut Health: Probiotics have been linked to alleviating symptoms of certain digestive disorders, such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD).
The Skepticism Surrounding Probiotics
While there is evidence to support the benefits of probiotics, there is also skepticism regarding their effectiveness. Some experts argue that the probiotic market is oversaturated with products that make exaggerated claims without sufficient scientific backing.
Frequently Asked Questions
- Do I need to take probiotics every day? – It depends on your individual needs and health goals. Consult with a healthcare provider for personalized recommendations.
- Are all probiotic supplements the same? – Not all probiotic supplements are created equal. Look for products that contain strains of bacteria known to have specific health benefits.
- Can probiotics help with weight loss? – While some studies suggest a link between gut health and weight management, more research is needed to determine the effectiveness of probiotics for weight loss.
In conclusion, while probiotics show promise in supporting digestive health and immunity, more research is needed to fully understand their impact on overall well-being. It is important to consult with a healthcare professional before starting any probiotic regimen to ensure that it is appropriate for your individual needs.
