What Is Meant by Probiotics?

Probiotics are called good and helpful bacteria. The meaning of probiotics is "for life" (pro-biota). Probiotics have been in our system since the moment of the formation of the fetus in the birth canal. Probiotics are bacteria and yeasts that are good for health, especially the digestive system, to keep our gut healthy.

What Are the Functions of Probiotics?

Probiotics refer to food and health products containing live beneficial microbes intended to enhance the populations within the gut and other areas of the body, aiming to bolster those communities. Their purpose is to prevent and address dysbiosis, characterized by an imbalance or shortage of beneficial microbes in the microbiome. Effective probiotics facilitate the incorporation of microbes into the body, supplementing the existing populations.

Varieties of probiotics exhibit distinct functionalities within the body. Consequently, certain types may be more or less beneficial for particular conditions. Additionally, probiotics lack FDA regulation, meaning manufacturers are not obliged to demonstrate the quality or composition of their products. Seeking advice from a healthcare professional well-versed in probiotics is advisable to determine which ones may be most effective for the requirements.

Under What Circumstances Are Probiotics Advised?

If a person experiences symptoms indicating dysbiosis in the digestive system or other areas, their healthcare provider may suggest probiotics to restore balance to their microbiome. Similarly, if the person has undergone an illness or treatment that has compromised the microbiome, their provider might recommend probiotics to aid in its restoration. For instance, they may advise incorporating probiotics following the completion of an antibiotic regimen.

Certain individuals opt for a daily probiotic supplement as part of their routine to support overall well-being. This choice may be particularly suitable for those susceptible to gut health issues who find it beneficial. A balanced gut microbiome can enhance overall immunity, mitigate inflammation, and promote regular bowel movements. Factors such as stress and dietary choices can adversely affect the gut microbiome, and probiotics serve as one method to aid in its restoration.

What Types of Probiotics Demonstrate Effectiveness?

For a probiotic to offer any health advantages, it should meet the following criteria:

  • It belongs to a type with established benefits for the body.

  • It exists in a form that is safe for consumption or application to the body.

  • Consists of viable microbes that have endured commercial processing.

  • Demonstrate the ability to withstand the passage through the digestive tract if it is taken orally.

Among the extensively researched and recommended probiotics are:

  • Various species within the Lactobacillus genus, such as L. acidophilus, L. casei, L. rhamnosus, and L. plantarum.

  • Various species within the Bifidobacterium genus, including Bifidobacterium breve and Bifidobacterium longum.

Lactobacillus acidophilus, commonly known as acidophilus, is one of the most recognized probiotics on the market today, possibly due to its versatile applications. Acidophilus naturally occurs in several body regions, including the gut, mouth, stomach, urinary tract, lungs, and vagina, aiding in the restoration of balance across these microbiomes.

These items are readily accessible without a prescription and are found in grocery stores, pharmacies, and health and wellness outlets. They are offered as dietary supplements in various forms such as capsules, liquids, or powders, as well as topical lotions or creams, catering to diverse needs. Consulting healthcare providers can assist in identifying a suitable option tailored to the requirements.

Probiotics are also available in milder concentrations through fermented foods and beverages like:

  • Cottage cheese.

  • Kombucha.

  • Pickles and pickle juice.

  • Yogurt and kefir.

  • Miso soup.

  • Sauerkraut or kimchi.

Consuming fermented foods and beverages is a method to increase probiotic intake in the gastrointestinal tract. However, it is important to note that food processing may occasionally eliminate these natural probiotics. Therefore, it is advisable to inspect labels for "live and active’’.

What Are the Uses of Probiotics?

The uses of probiotics are discussed below:

  • It will help move food through the gut in IBS, IBD (inflammatory bowel disease - inflammation in some parts of the intestine), diarrhea, fight food-borne infections, and Helicobacter pylori (H.pylori) infection.

  • It also helps in conditions like eczema.

  • Probiotics help maintain urogenital health and restore the balance of microflora of the vagina (yogurt is used as a folk remedy with limited support) and are also helpful in urinary tract infections.

  • It can reduce the risk of certain recurrent common infectious diseases.

  • It will reduce crying time in colicky babies.

  • It is beneficial for brain function, and it improves immunity function.

  • Lactobacillus probiotics are very useful in reducing bad cholesterol levels like LDL and blood pressure.

  • It also prevents allergies and colds and maintains good oral health.

What Are the Side Effects of Probiotics?

Probiotics are not all alike. The effect of probiotics varies from person to person. Although some probiotic formulations have shown scientific evidence to support the uses of probiotics, for most conditions, it is lacking. Information on long-term safety is limited. The common side effect of probiotics is diarrhea. The risk of serious side effects may be higher in people who have underlying health conditions. Though considered safe, there is a theoretical risk for people with impaired immune function.

Is It Good to Take Probiotic Supplements?

Probiotic supplements are nowadays gaining popularity, and everyone wants to take them. These supplements are available in the form of tablets, powders, or liquids. Recently chewable gummies have been introduced into the market. These chew gummies are a good option for those kids who do not like to take tablets, powder, or liquid. According to a survey, the third most popular dietary supplement among adults, after vitamins and minerals, was probiotics.

However, while taking these supplements, one should be aware of the fact that not all the probiotics supplements available on the market contain the same concentration of bacteria. All the prebiotic supplements do not work the same way. If individuals feel uncomfortable after taking this supplement, they should discontinue it. On the other hand, the probiotic supplement should only be taken with the advice of a healthcare professional. It should not be taken on their own just by getting fascinated with a probiotic advertisement that claims to improve health. This is because not everyone requires a prebiotic supplement, and not every supplement contains the same strain of bacteria.


To conclude, probiotics are considered to be a good health supplement for improving health conditions; however, more research still needs to be carried out to prove their efficacy. Some studies have shown that these supplements have improved some medical conditions, but it has not been proven that all probiotic supplements are good. Therefore, a healthcare provider should be approached before starting these supplements.
