Probiotics help to improve your gut microbiome. This is the good bacteria that live in your gut and help your digestive system function normally. The healthy gut microbiome has been linked to a number of potential health benefits. At the same time, increasing your intake of certain probiotic strains does come with some potential adverse effects.
While it is possible to get probiotics from food sources, many people prefer to opt for supplements that can give their body an adequate amount of these beneficial bacterium species. There are many supplements to choose from when you prefer to get your probiotics from a pill. The significant variety of these products can make it hard to know which one to choose.
We take a closer look at the variety of probiotic strains that may be included in these supplements. We also consider what the benefits and potential side-effects of these strains are. This will help you determine which strains are the most important for you, and ensure you know what to expect when taking these supplements.
What Are The Best Probiotic Strains?
There are more than 500 species of bacteria found in your gastrointestinal tract. Even though the diversity may seem limited, consider the fact that there may be billions of each bacterium species living in your digestive system. Each of the good bacterium species provides specific benefits for your gut or the rest of your body.
We will take a closer look at the primary strains that you should look for when buying a probiotic supplement. We will also look at the benefits that these offer you and the potential side-effects that you could experience.
Bifidobacterium Probiotic Strains
When you look at these products, Bifidobacterium is often one of the bacterium strains that you are going to find mentioned on the ingredient list. This is because this particular strain of bacteria tends to have several potential health benefits.
There are actually quite a few different bacterium species that fall within the Bifidobacterium family. The most popular of this family would be Bifidobacterium bifidum. This probiotic strain is often referred to as B. bifidum as well. There are several health benefits that have been associated with the consumption of this particular strain, in fact.
The use of a supplement that contains the B. bifidum bacteria strain may provide the following benefits:

B. bifidum may also be helpful in a condition known as necrotizing enterocolitis. This is an infection that affects the lining of your gastrointestinal tract. It is caused by bacteria that are considered harmful. The good bacteria may help to improve the control over the bad bacteria in your gut.
Individuals with an infection caused by the Helicobacter pylori bacteria, also called H. pylori, might also benefit from using a probiotic supplement that contains B. bifidum in particular.
Scientific Studies About The Benefits Of Bifidobacterium
It is always useful to consider scientific studies and research conducted on a probiotic strain before making a decision regarding the specific supplement to buy. There are several studies that have been conducted in order to show the potential benefits that Bifidobacterium species could potentially offer the human body.
Researchers at the Akdeniz University School of Medicine conducted a study to determine the efficacy of Bifidobacterium species in people with irritable bowel syndrome. The study utilized a specific strain of this bacteria, known as Bifidobacterium lactis B94.
The participants in the study were divided into three groups. Each group received a specific supplement or combination of supplements. The following supplements were provided:
- Group 1: Daily supplement with inulin and Bifidobacterium lactis B94
- Group 2: Daily probiotic supplement with Bifidobacterium lactis B94
- Group 3: Daily supplement with the prebiotic inulin
All participants in the study had previously been diagnosed with irritable bowel syndrome. Symptoms of IBS was active in all participants at the time of the study. A total of 71 patients participated in this study.
The use of the probiotic supplement yielded the following results:
- Participants experienced an improvement in belching-abdominal fullness
- There was a reduction in bloating following the consumption of a meal
When probiotics and prebiotics were combined, additional improvements were identified. Participants also experienced a reduction in mucus present in their feces. There was also an improvement in constipation symptoms among these participants.
In one review paper, researchers also found several Bifidobacterium strains that could potentially be useful in improving brain function. The review looked at 38 studies that were previously conducted. This included studies performed on both human and animal subjects.
Subjects of these studies reported signs of these conditions:
- Poor memory function
- Obsessive-compulsive disorder
It was found that several species within the Bifidobacterium family may help to improve symptoms associated with these particular conditions. The specific Bifidobacterium strains mentioned in the study included the following:
The use of supplements that contain Bifidobacterium may also lead to certain side-effects. It is important to realize what to expect and the specific side-effects that could develop when you turn to these supplements.
Potential side-effects that you could experience if you take Bifidobacterium supplements include:

This is a gram-positive type of bacteria that is part of the lactic acid group of bacteria.
There are several reasons why people might want to turn to Lactobacillus supplements in order to benefit their health. Some of the conditions and benefits that may be experienced when you take a supplement with this family of bacterium species include:

A study in the World Journal of Gastroenterology found that Saccharomyces supplements may be highly effective at treating diarrhea caused by antibiotics. The same study found that these supplements are useful for treating and preventing traveler’s diarrhea.
Another study found that Saccharomyces can also be useful in reducing the effects of ulcerative colitis in the body. Additionally, the anti-inflammatory effects also seem to help reduce the side-effects of inflammatory bowel disease.
Saccharomyces supplements are generally considered safe. There are a few side-effects to take note of.
