Benefits of probiotics in 2022

Probiotics are live bacteria and yeasts that may benefit human health. They are found in the human digestive system and in some foods and nutritional supplements. Below we will review the benefits of probiotics.

Probiotics are beneficial bacteria. They are found throughout the body, although people largely associate them with the stomach and intestines. As evidence of a link between the gut microbiome and overall health, interest in probiotics is growing.

People often consume probiotics in hopes of balancing the gut flora, also known as the gut microbiome.

There are many strains of probiotic bacteria, but the main strains are from the Lactobacillus or Bifidobacterium groups.

Food sources of probiotics include some foods such as some yogurt and kimchi. Probiotic supplements are also available.

**Probiotics may benefit the body in several ways, such as:

***Health benefits of probiotics

Promote a healthy gut microbiome

Rebalancing the microbiome after illness or treatment

Immune system support

Probiotics may benefit people with various health conditions. However, determining exactly who will benefit from which type of bacteria will require further research.

Here are some of the ways probiotics may help keep you healthy.

***Probiotics and Diarrhea

Certain strains of probiotics have shown positive results in treating diarrhea and gastroenteritis inflammation of the intestinal lining, which can cause diarrhea.

A 2011 research concluded that probiotics may help combat various forms of diarrhea, including intermittent infectious diarrhea, acute watery diarrhea, and diarrhea due to rotavirus.

However, the effects will likely depend on the type and dose of the probiotic.

***Probiotics and mental health

Studies have indicated a link between the gut microbiome and the central nervous system, including the brain. This connection is known as the gut axis.

Some scientists believe that bacteria in the gut can affect the nervous system and the way people think and feel.

The findings suggest that probiotics could one day support the treatment of mental health problems, such as anxiety and depression, and possibly some neurological conditions as well.

***Probiotics and high cholesterol

A 2017 review concluded that eating foods containing the probiotic Lactobacillus bacteria can reduce levels of low-density lipoprotein, or "bad" cholesterol, as well as total cholesterol.

In 2018, the authors of a "meta-analysis" also looked at the effect of probiotics on total cholesterol.

After studying data from nearly 2,000 people, researchers concluded that probiotic supplementation can significantly reduce total cholesterol levels in the blood.

However, effectiveness may depend on the type and dose of the supplement. More studies are needed to confirm the results and clarify which probiotics would be beneficial.

***Probiotics and high blood pressure

One review found that milk fermented with Lactobacillus strains may help lower blood pressure.

The review also showed that taking probiotics can lead to increased levels of vitamin D - which helps prevent high blood pressure.

If additional research confirms that probiotics can help manage blood pressure, these bacteria may one day play a role in treating and preventing heart disease.

***Probiotics and Irritable Bowel Syndrome or Inflammatory Bowel Syndrome

There is evidence that probiotics may help treat irritable bowel syndrome (IBS). 2019 research concluded that a multi-strain probiotic may improve IBS symptoms.

The researchers called for further investigations into whether Akkermansia, Bacteroides and Faecalibacterium strains could play a role in future treatments.

A different 2019 review found that probiotics do not consistently support treatment of inflammatory bowel disease, or IBD, with the exception of one type of disease: ulcerative colitis.

***Probiotics and infection

In lab tests, scientists have found that a specific form of the probiotic bacteria Lactobacillus paracasei may protect the intestines from infection with Listeria, one of the most harmful bacteria.

A 2017 review found additional evidence that probiotics can help treat and prevent Listeria infection. If probiotics prove beneficial, they are less likely to upset the microbiome balance as antibiotics do as a treatment for this infection.

***Probiotics, Psoriasis, and Chronic Fatigue Syndrome

In 2013, researchers found evidence that Bifidobacterium infantis 35624 could benefit people with conditions such as psoriasis and chronic fatigue syndrome.

This specific type of bacteria is often included in nutritional supplements to strengthen the digestive system.

*** Sources of probiotics in food

Foods that contain natural probiotics include some types of:


Milk kefir (Indian mushrooms)


soft cheese

Soy-based products, such as miso, tempeh, and some soy drinks


Unpasteurized sauerkraut

the juice


Many products are marketed as containing probiotics, but only some of the elements are likely to benefit the body. Eating soft cheese, for example, may be a good way to ensure that probiotic bacteria are beneficially reaching the intestines.

***Probiotic Supplements

Probiotics are available as supplements, although there isn't enough evidence yet to prove that a particular brand or type will help with a particular condition.

The Food and Drug Administration (FDA) regulates probiotics for medicinal purposes. However, they do not consider probiotic supplements to be a drug and therefore do not monitor claims about probiotic contents. No one can be completely sure of the content of the product.

Also, it is not always clear how long probiotics remain active in the body.

As a result, no one can be sure how effective any product is likely to be or the condition in which it might help.

***Risks and Precautions

Probiotics are likely safe for most people, but there are some points to consider before using or increasing your intake.

The National Center for Complementary and Integrative Health notes that although probiotics are likely safe for those who are otherwise healthy, these bacteria may pose a risk to people with weakened immune systems or other health problems.

These people may be at risk of:


Harmful substances released in the body

antibiotic resistance

It is always best to check with a doctor before taking supplements or making major dietary changes, especially for people with existing health problems.
