21 Incredible Probiotics Facts That Will Amaze You


Probiotics have gained significant popularity in recent years due to their potential health benefits. These live microorganisms, often referred to as “good bacteria,” are believed to improve gut health and enhance overall well-being. In this article, we will delve into the world of probiotics facts, exploring their definition, types, benefits, and considerations for incorporating them into your daily routine.

What Are Probiotics?

Probiotics are live microorganisms that, when consumed in adequate amounts, provide health benefits to the host. They are typically bacteria but can also include certain yeasts. These beneficial bacteria can be found in various fermented foods, such as yogurt, sauerkraut, and kefir, as well as in dietary supplements.

Types of Probiotics

There are several types of probiotics, with the most common being Lactobacillus and Bifidobacterium. These two genera encompass numerous species and strains, each with its unique characteristics and potential health benefits. Other less commonly used probiotic strains include Streptococcus, Saccharomyces, and Escherichia.

Probiotics Facts

Probiotics Facts

There Are Many Probiotics Facts , I Have mentioned Some of them below:

1) Probiotics In Our Body Outweigh Our Brain

Typically human brain weighs about 3 pounds, and a healthy human body will have over 3.5 pounds of probiotic bacteria and organisms (according to Casey Adams Ph.D. The fact that our heavyweights are only 0.7 pounds, and our liver weighs about 4 pounds, makes our probiotic bacteria one of the largest organs in our body.

2) There Are 10 Times More Probiotics Than Cells In Our Body

In a healthy person, there are more than 100-300 Trillion probiotic bacteria and yeast, compared to only 10 trillion cells in our body. According to Mary Ellen Sanders, if the bacteria in our body were laid end to end, they would encircle the globe 2.5 times.

3) The Probiotics Market Is Huge

According to MARKETS, probiotics are a 16 billion dollar market. Moreover, as of 2008, there were more than 500 probiotic food and beverage products have been introduced in the last decade. And these numbers are only expected to grow as holistic health treatments become ever more pervasive.

4) Probiotics Live Throughout Our Entire Body (Not Just Our Stomach!)

The largest number of probiotics live in the colon, but billions also live in the mouth, oral cavity, nasal cavity, esophagus, around the gums, and, in the pockets of our pleural cavity (surrounding our lungs). They dwell within our stomach, our intestines, within the vagina, and around the rectum. within joints, under the armpits, under the toenails, between the toes, urinary tract, inside our urinary tract, and many other places!

5) The Appendix Is Not Useless – It Incubates Probiotics

In the past, the appendix was largely thought to be useless. Appendicitis, a life-threatening condition, would call for the removal of the appendix. In 2007, Randal et al. at Duke University conducted research into the vermiform appendix. The researchers observed that when the body was under attack by pathogens, the appendix would release probiotic bacteria that would perfectly counter the specific type of invaders. The appendix does this by releasing them into the cecum when the body is infected.

6) Probiotics Fight Cancer, Colds, and Constipation

It may not surprise you to hear that probiotics can reduce constipation (Italy, Amenta et al. 2006). But what may surprise you, is that probiotics play a role in cancer. They have been shown to stimulate the production of anti-cancer chemicals (Hatakka et al. 2008). The probiotics, Lactobacillus casei, have also been shown in Tokyo to reduce the risk of bladder cancer, depending on frequency and dosage (Ohashi et al. 2002).

Numerous probiotics have been shown to fight viruses such as colds, the flu, rotavirus, herpes, and ulcers. In New Delhi, 100 children ages 2-5 were given L. acidophilus for 6 months. These children have fewer incidences of colds, flu, diarrhea, and fever than the placebo group (Saran et al. 2002).

7) There Are More Than 100 (known) Benefits To Taking Probiotics

According to the book, Probiotics by Casey Adam Ph.D., there are more than 100 benefits to supplementing with probiotics. Hundreds of studies have shown different species of probiotics have different health benefits (see the full list of probiotic benefits here).

However, we must take these probiotics in their proper context. For example, almost every probiotic study requires the patient to take large, therapeutic doses, for at least two monthsOftentimeses, the studies conferred the benefits after an entire year of daily large-dose supplementation.

8) Probiotics Are Responsible For 70% Of Our Immune Response

According to Casey Adams Ph.D., probiotics play a role in 70-80% of our immune response. Probiotics stimulate everything from T-cells to macrophages. Probiotics also activate cytokines and phagocytic cells to coordinate the immune response.

9) Probiotics Produce Antibiotic Chemicals

In the book Probiotics, Protection Against Infection, Casey Adamas writes:

“To protect against pathogens, [probiotics] will produce a number of natural antibiotics designed to reduce the populations of [pathogenic bacteria]…”

Moreover, these antibiotic substances are perfectly tuned to kill the invading pathogens. And if the pathogens become resistant to that chemical, then the probiotics will change strategies and produce a new, more effective antibiotic chemical.

Contrast this dynamic probiotic strategy to our static, oral antibiotics which must be phased out every few years (as pathogens evolve antibiotic resistance). While we may be able to continue to discover new antibiotic substances, nature will always win in the long term. The bacteria will always evolve resistance. This is illustrated by the fact that bacteria can even survive in nuclear waste!

10) Antibiotics Nuke Our Body’s Immune System

It is well known that antibiotics kill bacteria and can make us better. But what isn’t well known, is that antibiotics also kill our good bacteria. Since probiotics comprise 70-80% of our immune response, antibiotics will kill our immunity.

The moment our probiotics are gone, opportunistic parasites, fun, gi, and pathogenic bacteria rush in to fill the ecological void. Moreover, this use of antibiotics will creat-drug-resistant bacteria that can’t be defeated by antibiotics.

11) Probiotics Easily Kill Antibiotic-Resistant Bacteria

The use of antibiotics can create antibiotic-resistant superbugs, MRSA (multi-drug resistant Staphylococcus aureus) is immune to many different antibiotics…and in some cases, they are immune to all antibiotics known to man.

However, probiotics can defeat the superbugs with ease. Probiotic bacteria and pathogenic bacteria have been fighting for billions of years. And healthy humans have the perfect environment for probiotic bacteria to beat pathogenic bacteria. The fact that humans have been surviving before the invention of antibiotics is proof of how powerful probiotics are.

12) Probiotics Will Be The 21st Century’s Antibiotics

Valery V. Smirnov writes,

“… 21st century probiotics will successfully rival traditional drugs on the pharmaceutical market, especially those used for disease prevention purposes…”

The profound point Dr. Smirnov is making is that probiotics will be the antibiotics of the 21st century. This is because their effective medical implementation will revolutionize our perspectives on disease in the way antibiotics did before.

13) 400 Strains Of Probiotics Live In Our Bodies

According to numerous research studies, there are well over 400 probiotic strains resident in our bodies. Some of these probiotics are permanent residents, and others are transient. Interestingly, only 20 strains account for 75% of the mass of bacteria that live in our bodies.

Numerous scientists also argue that the combined DNA of our probiotic residents is more important to our survival than our DNA.

14) Probiotics Are Bacteria And Fungi That Make Us Healthy

The World Health Organization probiotics definition is “live microorganisms which when administered in adequate amounts confer a health benefit on the host.” These probiotic organisms can be yeasts (fungi), good bacteria or even organisms commonly found in soil.

The difference between normal pathogenic bacteria or candida and probiotics is that probiotic organisms have a symbiotic relationship with our bodies. Our bodies and probiotic organisms have formed a mutual defense treaty. And while we are extremely fearful of bacteria and fungi, specific probiotic strains are very beneficial to our health.

15) Probiotic Foods Have Been Healing For Millennia

Numerous traditional probiotic foods are extremely tasty and healthful. These foods have been restoring health for millennia. Foods like natto, miso, kimchi, tempeh, sauerkraut, kefir, kombucha, and lassi all have very rich cultural heritages and medicinal benefits.

16) Probiotics Can Decrease Lactose Intolerance

In a 1996 study, Jiang et al. studied milk containing B. Longumgrown in a medium rich in lactose. He found that when lactose-intolerant individuals consumed this special milk, they showed significantly fewer symptoms of lactose intolerance. They have been numerous studies that have shown probiotics to help decrease lactose intolerance.

17) Are You Getting Your Vitamins? Better Get Your Probiotics.

It has been proven that probiotics produce a huge number of vitamins, such as:

  • Vitamin A
  • Vitamin K
  • Vitamins B1-B3, B5-B7, B9, B12
  • Essential Fatty Acids

So perhaps the need for B-vitamin supplementation is a call for proper probiotic colonization. I look forward to the day when probiotic companies and organic food companies put vitamin companies out of business.

Additionally, probiotics also increase the digestibility, bioavailability, and processing of a large number of nutrients, including:

  • copper
  • calcium
  • magnesium
  • iron
  • manganese
  • potassium
  • zinc
  • proteins
  • fats
  • carbohydrates
  • sugars
  • milk
  • phytonutrients
  • cholesterol

These lists are both by Casey Adams, Ph.D. in his book, “Probiotics – Protection Against Infection”.

18) Supplemented Probiotics Don’t Remain In The Body

It is interesting to note that no study has shown that supplemented probiotic strains remain in the body for more than two weeks. At the National University of Singapore, Mah et al. infants were given probiotic supplements for the first 6 months of their life. During these 6 months of supplementation, the supplemented probiotic strains were present in the infants’ feces. However, within weeks of stopping the supplementation, the probiotic strains were no longer found in the feces.

The results of this study and the results of other research suggest that supplemented probiotics assist our native probiotic strains. The foreign probiotic strains form a beachhead for our native probiotics and allow our probiotics to proliferate. This situation is analogous to a foreign arm invading a country, fighting one “evil” faction, and allowing another “good” faction time to proliferate.

19) Vaginal Birth Is Our First Dose of Probiotics

It’s no secret that a healthy, loving mother is key to a healthy child. And a healthy mother will have a vagina lined with probiotics to fend off invaders. What isn’t well known, is that when a baby experiences a vaginal birth, the baby gets its first dose of probiotics. 60% of vaginal births will give infants their first probiotic inoculation of Bifidus Infantis. However, only 1% of cesarean section births will give infants B. Infantis inoculation, according to “Probiotics” by Casey Adams.

After getting a dose of probiotics from a vaginal birth, the consumption of breast milk gives more probiotic inoculation. Mother’s colostrum has up to 40% probiotic content.

20) Probiotics Are Good For Infants

In a 2004 study, Saavedra et al. gave infants, average age 2.9 months, B. lactis or S. thermophilus for 210 days. The infants who were given the probiotics have a lower frequency of colic and needed fewer antibiotics compared to the control group.

In an Estonian study by Vendt et al. 2006, preterm infants L. rhamnosus GG until they were six months old. The infants given probiotics had grown more than the placebo group.

21) Probiotics Are Vital For Women’s Health

Both oral probiotics and douching supplementation can prevent and cure vaginitis and vaginosis. An interesting study on probiotics and vaginosis was conducted in 2007 by the University of Milan (Dragoet al). They found that after a 6-day daily douche of Lactobacillus acidophilus and Lactobacillus paracasei F19, 92.5% of women had their vaginosis cured. The fishy order was cured in all women. The pH levels of women were normalized to 4.5 in 34 out of 40 women.

Probiotics have also been shown to reduce mastitis.

The Future of Probiotic Research

The field of probiotic research continues to evolve rapidly. Scientists are exploring new strains, delivery methods, and applications for probiotics. Future research may uncover additional health benefits and provide more personalized recommendations for probiotic use based on an individual’s unique gut microbiota composition.


Probiotics are live microorganisms that offer potential health benefits, particularly for gut health, immune function, and mental well-being. Incorporating probiotics into your diet through fermented foods or supplements can be a valuable addition to a healthy lifestyle. Remember to choose probiotic products carefully, consider individual needs, and consult with a healthcare professional when necessary.


1. Are probiotics safe for everyone?

Probiotics are generally safe for most people, but individuals with compromised immune systems or serious health conditions should consult a healthcare professional before starting probiotic supplementation.

2. Can probiotics help with weight loss?

While probiotics may have some indirect effects on weight management, they are not a magic solution for weight loss. A healthy diet, regular exercise, and lifestyle factors play a more significant role in achieving and maintaining a healthy weight.
