Probiotics as a nutritional supplement

Ah, probiotics, the beneficial bacteria that have captured the attention of health enthusiasts and researchers alike. Let’s explore the world of these living microorganisms and their potential benefits for our gut health.

Probiotics are live bacteria and yeasts that are considered “good” or “friendly” for our bodies, particularly our digestive system. They are naturally present in certain foods and can also be consumed in the form of supplements. These microorganisms, mainly from the Lactobacillus and Bifidobacterium genera, are believed to promote a healthy balance of bacteria in our gut microbiome.

Our gut microbiome is home to trillions of microorganisms, including both beneficial and harmful bacteria. Maintaining a healthy balance of these bacteria is crucial for our overall well-being, as they play a vital role in digestion, nutrient absorption, immune function, and even mental health.

Probiotics have been studied extensively for their potential health benefits. They can help restore and maintain a healthy gut microbiota by colonizing the intestines and competing with harmful bacteria for resources. This can help improve digestion, alleviate symptoms of gastrointestinal disorders like irritable bowel syndrome (IBS), and promote regular bowel movements.

Furthermore, probiotics are believed to have immune-modulating effects. They can strengthen the gut barrier, enhance immune response, and reduce inflammation in the gut. This may lead to a reduced risk of certain infections, such as urinary tract infections and respiratory tract infections, as well as a potential improvement in allergic conditions.

Research has also shown promising evidence for the role of probiotics in supporting mental health. The gut-brain axis, a bidirectional communication pathway between the gut and the brain, is believed to be influenced by the gut microbiota. Probiotics may help regulate this axis and potentially alleviate symptoms of anxiety, depression, and stress-related disorders.

While the potential benefits of probiotics are intriguing, it’s important to note that the effects can vary depending on the specific strains and dosages used, as well as individual factors. It’s always recommended to consult with a healthcare professional before starting any new supplement regimen.

Probiotics can be found in various food sources, including yogurt, kefir, sauerkraut, kimchi, and other fermented foods. Additionally, there is a wide range of probiotic supplements available on the market, each with different strains and formulations.

Incorporating probiotics into our diet may offer a natural and gentle approach to supporting our gut health and overall well-being. However, it’s important to remember that they are not a cure-all solution and should be used in conjunction with a balanced diet and healthy lifestyle practices.

Thank you for joining me on this exploration of probiotics. May it deepen your understanding of these fascinating microorganisms and empower you to make informed choices for your gut health. Until next time, embrace the power of the gut microbiome and nourish your body from within!

What does probiotic mean?

The term suggests an antagonism with antibiotics and indeed, instead of destroying life, probiotics are life enhancers. Yet there is an interaction between probiotics and antibiotics. The word probiotic was coined in 1965 by DM Lilly and RH Stillwell in their article Probiotics: growth-promoting factors produced by microorganism , in the scientific journal Science .

What are probiotics?

Probiotics fall under the so-called healthy bacteria. They are therefore living substances that consist of bacteria or yeasts. Yeasts are single-celled fungi. They are normally present in our intestinal flora, but can also be added to our system in large doses. Probiotics are usually used as a nutritional supplement, although also as a medical preparation. Of the many possible bacteria, lactic acid bacteria will often be used.


In popular magazines and professional literature, probiotics are praised for their beneficial effect on:

  • the immune system
  • better digestion
  • rehabilitation of the intestine after deterioration due to excessive antibiotics
  • problems with poor digestion of dairy products
  • a balanced intestinal flora
  • some allergies
  • certain ear, nose and throat diseases
  • combating diarrhea
  • stress
  • resistance to gifts

Not all of these effects have been proven.

Where are probiotics available?

Various types of probiotics are offered as nutritional supplements in health food stores or at pharmacies.
In the regular food trade we find them as an additive in certain dairy products.
