Latest Research: 7 Health Benefits of Probiotics (October 2023)

Are you looking for the latest research on the health benefits of probiotics?

If so, you are in the right place.

Today, I discuss the latest research on the benefits of health probiotics as of October 2023.

In This Article:

Let’s begin by discussing the latest research on the benefits of probiotics in reducing oxidative stress.

Oxidative Stress

Oxidative Stress occurs (OA) due to an imbalance between the production and accumulation of reactive oxygen species (ROS) and the ability of the body to detoxify these products in cells and tissues.

Reactive oxygen species (ROS) can damage cells’ DNA, proteins, and lipids.

A recent research paper looked at the results of 9 Randomized Control Trials (RCTs) on the effects of probiotics on Oxidative Stress(OS) in healthy people.

The researchers concluded that probiotics led to a substantial reduction in OS compared to a placebo.

The administration of probiotics to healthy individuals suggests the potential for chronic illness prevention.

Let’s discuss how probiotics can benefit those with Asthma.


Asthma is a respiratory condition that affects both children and adults and is characterized by symptoms such as wheezing, difficulty breathing, chest tightness, and coughing, particularly at night or in the early morning.

A recent research paper discussed the results of a randomized control trial on the effects of probiotics on Asthma.

Compared to placebo, probiotics improved asthma symptoms and reduced inflammation.

Interestingly, the authors concluded that OS is responsible for asthmatic inflammation.

Let’s discuss how probiotics can benefit those with Seasonal Allergies.

Seasonal Allergies

Seasonal allergies or Allergic rhinitis is inflammation of the inside of the nose caused by an allergen such as pollen, dust, mould, or skin flakes from certain animals.

A recent randomized controlled trial (RCT) found no difference in allergy symptoms with probiotics for seasonal allergies.

However, when we look at the findings of an earlier systemic review and meta-analysis of 56 RCTs, the authors concluded there is considerable evidence that probiotics help treat allergic rhinitis.

While single trials provide significant results, comparing and considering the weight of research findings is essential.

Let’s discuss how probiotics can benefit children with diarrhea.

Children with Diarrhea

Diarrhea is a common symptom of illness in young children, characterized by loose, frequent bowel movements.

A recent systematic review and meta-analysis of nine RCTs found that when compared to a placebo, probiotics reduced the frequency and severity of diarrhea.

However, the use of probiotics did not show any significant effect on the prevention of diarrhea.

This study used a single species; however, in general, probiotics are not specific to symptoms, and the vast body of research has shown that a mixed-blend is most beneficial.

When administering probiotics to infants, giving them between one-fifth and one-quarter of the adult dosage is recommended.

Let’s discuss how probiotics can benefit IBS.


Suppose you are experiencing recurring abdominal pain and changes in bowel movements, which may be diarrhea, Constipation, or a combination of both. In that case, you may be dealing with irritable bowel syndrome (IBS).

IBS is a collection of symptoms that typically occur together and can be challenging.

It’s important to note that you experience these symptoms with IBS without any observable evidence of damage or disease in your digestive tract.

A recent systemic review and meta-analysis of 6 RCTs found that probiotics reduced abdominal pain and bloating compared to placebo.

Let’s discuss how probiotics can benefit Constipation.


Constipation is when you may experience fewer than three bowel movements per week.

The stools may be hard, dry, or lumpy, making passing difficult and painful.

You may also feel that not all the stool has passed.

A recent RCT using a single-strain probiotic, P9, found that after one month, compared to a placebo, the probiotics increased bowel movement frequency, less straining and less concern related to Constipation.

Another RCT comparing the effect of P9 with another strain showed that both strains reduced constipation.

This finding again emphasizes that it does not matter what strain you use.

Another RCT showed that probiotic benefits for constipation are usually seen after two months, which is longer than the duration of this study.

Let’s discuss how probiotics can benefit H.Phylori infection.

H.Phylori infection

H. pylori is a bacterium that can infect the stomach or small intestine and is the leading cause of peptic ulcer disease.

A recent systemic review and meta-analysis of 17 RCTs found that probiotics alongside standard antibiotics therapy led to a 3.7 greater eradication rate, less abdominal pain and fewer medication side effects.

These findings further confirm the benefits of taking probiotics alongside antibiotic therapy, such as Refaximin, for SIBO.
