  8. Sourdough or natural yeast: it is a live culture composed of yeast and bacteria that are produced through the fermentation of cereals such as wheat and microorganisms that are naturally found in the environment, being used to make various products such as bread, cakes and cookies.

In addition to this, some cheeses may also contain live cultures of microorganisms with probiotics' health benefits, and it is important to read the nutritional labeling to confirm whether or not this type of cheese contains these bacteria.

Experts say that to maintain healthy intestinal flora, it is advisable to consume at least 1 probiotic source food per day, especially after the use of antibiotics that end up affecting the healthy intestinal flora. An apple a day keeps the doctor away, and a kefir a day guarantees probiotics' health benefits. That's not a rhyme, it's a fact!

Probiotic Supplements

In addition to food, probiotics can also be consumed as supplements and there are several presentations: capsules, liquids or sachets, which must be diluted in water or natural juices to be consumed.

You will find many commercial names, all of them containing the right amount of probiotics' health benefits.


There are several types of supplements, which include between 1 to 10 different types of probiotics. The most important are usually:

  • Bifidobacteria animalis: helps strengthen the immune system, as well as facilitating digestion and fighting bacteria transmitted by ingesting contaminated food;
  • Bifidobacteria bifidum: are present in the small and large intestine, helping in the digestion of dairy products;
  • Bifidobacteria breve: are present in the intestine and vaginal tract helping to fight bacterial and fungal infections;
  • Bifidobacteria longum: is one of the most common types of probiotics in the intestine and helps eliminate toxins from the body;
  • Lactobacillus acidophilus: is perhaps the most important type of probiotics, as it aids in the absorption of various nutrients, as well as fighting infections and facilitating digestion. L. acidophilus are also present in the vagina, helping to fight infections;
  • Lactobacillus reuteri: are present especially in the mouth, stomach and small intestine, being important against Helicobacter pylori infection;
  • Lactobacillus rhamnosus: they are present in the intestine and can help to quickly combat cases of diarrhea, especially when traveling to other countries. It can also help treat acne, eczema and candida;
  • Lactobacillus fermentum: help neutralize products and toxins released during digestion, improving the environment for the growth of intestinal flora;
  • Saccharomyces boulardii: helps treat antibiotics for traveler's diarrhea.

The greater the diversity of probiotics, as well as the number of bacteria within each tablet, the better the supplement will be and the better the probiotics' health benefits, as it will facilitate the balance and faster development of a healthy intestinal flora.

How they should be ingested?

It is recommended that the supplement has between 2 to 10 billion active bacteria, being important to read the label of the product that should indicate the amount of organisms per dose, what type of bacteria it has because it is important to choose the one that is best according to the problem to be treated and in what dose it should be taken.

It is important to try the supplement for about 4 weeks, if there is no improvement during this period, the ideal would be to try a different supplement. Probiotics should be ingested before or after a meal, so that the food helps the bacteria to survive the gastric acid and reach the intestine, where they can multiply more easily.

It is important to remember that in addition to the consumption of probiotics in the form of supplements or foods rich in these bacteria, it is also important to maintain a healthy diet rich in fiber, since fiber is the main food for probiotics, favoring their survival in the intestine.

Difference Between Prebiotics and Probiotics?

While probiotics are healthy bacteria that inhabit the gut, prebiotics are fibers that serve as food for probiotics and promote their survival and proliferation in the gut.

Some examples of natural prebiotics are oats, onion, garlic, green plantain and green plantain biomass.

So, there is no doubt about how good probiotics are. They are in our body but consuming supplements or foods rich in them helps our body maintain balance and give us the best it has every day. Have you already chosen how to consume them?
