Questions to Consider Before Buying probiotic supplements

What is a probiotic?

Probiotics increase overall health. This is due to the intestinal flora, which has a great influence on our psyche. Thus, they not only have a positive influence on our immune system but also on our emotions.

They consist of living microorganisms, such as lactic acid bacteria, which are added to various foods and have a positive influence on our intestines. But not only that, they also activate immune reactions throughout the body, including the activation of defense cells, the so-called T cells.

There are around 400 to 500 types of bacteria in our gastrointestinal tract. These would weigh around 1.5 kilograms.

Our gastrointestinal tract, spread out flat, would be the size of a tennis court.

An intact intestinal flora is colonized by good probiotic bacteria and is therefore impermeable to certain toxins. This also ensures that vitamins, minerals and nutrients from food can be better absorbed by our body. In our intestines, 85% of the intestinal flora should consist of beneficial bacteria, as 80% of our immune system is located there.

Several criteria must be met for bacteria to have a probiotic effect:

  • They need to be taken orally.
  • They have to reach the intestines alive by being resistant to stomach and bile acids and being able to grow without oxygen.
  • They have to be healthy and non-disease-causing bacteria.

Who should use probiotics?

Probiotics are basically suitable for anyone who wants to support their intestines, but taking them also helps with many diseases. Therefore, even infants and children can consume probiotics.

In healthy children, there should be no problems with taking probiotic food supplements, but this should always be discussed with the treating pediatrician.

If the intestinal flora is out of balance, they are also used for intestinal cleansing. This occurs, for example, after antibiotic therapy, as antibiotics not only fight bad but also useful bacteria and thus damage the intestinal flora.

What are the alternatives?

Fermented foods, such as sauerkraut and yogurt, are known as probiotics. You can integrate such foods into your daily diet, but you can never say exactly how many bacteria are actually there and what effect they have on us.

What types of Probiotic supplements are there and which one is right for you?

If you’re looking to buy a probiotic, there are several alternatives you can choose from. Sometimes are:

  • Probiotics in capsule form
  • Probiotics in tablet form
  • Probiotics Powder
  • Probiotics in liquid form

Depending on what you prefer and under what circumstances you want to get the probiotic, it depends entirely on you what you choose. With the following section we want to make your decision easier.

Probiotics in capsule form: Advantages & Disadvantages

Probiotics in capsule form are the most common and therefore the easiest to find. You have to pay attention to whether these need to be cooled or not. If you know that you will not be able to cool these capsules for a long time, then you should perhaps opt for a different brand and even a different dosage form.

This is because the probiotic bacteria in the capsules are sensitive to moisture but also to heat. But nowadays, thanks to the so-called freeze-drying of probiotic bacteria, it is possible for many manufacturers to forego such instructions. In addition, modern packaging techniques, for example with a special seal or a blister pack, contribute to this. So you can easily store them in a dry, cool and dark place.

The typical shell of the capsule consists of animal gelatin, which is gastric acid resistant. But capsules with a vegan shell, which are also often found in stores, are becoming increasingly popular.

Probiotics in tablet form: Advantages & Disadvantages

With probiotics in tablet form, it is often more difficult to keep the bacterial cultures alive. This cannot always be guaranteed due to the manufacturing process of the tablets and therefore usually have a lower effect than the other dosage forms mentioned.

During production, the ingredients are compressed and then the tablets are coated with a lubricant such as talc, which makes them easier to swallow. This compression is not suitable for living microorganisms, as is the case with probiotic bacteria. further fillers are also added to bind the ingredients. These are not easily metabolized by the human body, which is why the probiotic bacteria are also tough.

Probiotics Powder: Advantages & Disadvantages

Robiotics in powder form make it easier to dose yourself, making it easier to creep into everyday life. It is particularly good if the body reacts to something again when it is not known exactly.

Many probiotics contain sugar and prebiotics, which are the basic nutritional basis for the probiotic microbiome. These are particularly important if the preparation is not gastric acid-resistant, as they ensure that the bacteria arrive in the stomach undamaged.

In addition, digestive problems can be exacerbated by these additives. If you now mix the probiotic with water, this already starts with the metabolism of the sugar and the prebiotics. The longer this has been mixed and not drunk, the less likely it is that these additives will get into the intestines.

Probiotics Powder: Advantages & Disadvantages

Liquid probiotics are a good alternative for people who cannot swallow tablets or capsules. They often contain sugar, which is often converted into lactic acid during fermentation.

It should be stored well in the refrigerator, although it still has a shorter shelf life than the other dosage forms.

Purchase criteria: Use these factors to compare Probiotic supplements

In the following we will show you which aspects you can use to decide between the multitude of possible probiotics.


The criteria that you can use to compare probiotics include:

  • Quantity
  • Quality
  • Dosage
  • Ingredients

In the following paragraphs we will explain to you what is important for the individual criteria.


With the amount you should make sure that you get enough for the price paid. You have to differentiate between the different dosage forms and how much you get for the product you are looking for for a reasonable price.


The quality of probiotic preparations must be checked very carefully, as you cannot give your body anything. It is therefore recommended that the country of manufacturer is within the European Union. Here, strict regulations have been drawn up for those whom we can trust.


As mentioned above, there are many different dosage forms. You can choose between probiotics in capsule form, in tablet form, in powder form and in liquid form. So everyone has a free choice and does not have to limit themselves to anything.

It all depends on the person themselves what they get down and what is rather unpleasant. Capsules and tablets are therefore not particularly suitable for people with a particularly strong gag reflex, so they should rather use the powder and the liquid probiotic.

The same goes for people who prefer to get the whole thing over with faster


When it comes to the quality of probiotics, you should not only look at the country of manufacture, but also take a closer look at the ingredients. This includes the number of bacterial strains, that active bacteria are included and that there are no unnecessary additives.

The probiotic should have a relatively high number of bacterial strains, as this allows a greater effect to be achieved. At best, this should be over 10 strains of bacteria. It should also contain live and non-inactive probiotic bacteria. Furthermore, it should be free of flavors and other release agents.

Facts about Probiotics

When and how much probiotics should you take every day?

It is recommended to take probiotics without gastric acid-resistant capsules on an empty stomach, as the probiotic bacteria get into the intestines faster and the stomach acid does not have a major influence on it. After about half an hour, the majority of the probiotic bacteria should have arrived in the intestines.

If you now take the probiotics during the meal, then the food should not be too fatty or too protein-rich, as this would otherwise lead to an increased release of gastric acid and digestive enzymes. These in turn attack the probiotic bacteria.

How Long Should You Take Probiotics?

There is not much that can be said about taking probiotics, as it depends on the individual and their symptoms. It is usually best to take it for 4 to 12 weeks. If you take this during antibiotic therapy, you should take it for at least 3 weeks.

In the case of irritable bowel syndrome, 8 weeks of intake is recommended. In the case of gastrointestinal complaints, however, short-term use of probiotics is not very useful. Here you should take it for at least 9 to 240 weeks.

How long can probiotics be kept and how should they be stored?

The most important information, such as the storage and shelf life of food supplements, is either printed on the packaging or on the instructions. While it is now possible to store some probiotic strains without refrigeration, it is recommended that the probiotics be kept in the refrigerator.
