Although lactic acid bacteria are not problematic for us humans because we have had them in our food chain for centuries, caution is advised with newer probiotic bacteria strains.

They could put your bacteria in the gut in an unfavourable position, transfer antibiotic resistance or even cause infections.


Why are probiotic capsules important?

Because of their positive effects, probiotic capsules Probiotic capsules are important for certain health aspects. For example, the capsules can alleviate problems with the gastrointestinal tract or can also strengthen the immune system.

Did you know that the ratio of bacteria to body cells in humans is 10 to 1?

This sounds more dangerous than it really is, because most of these bacteria are quite harmless and "live" in your intestines. In fact, your health depends in many ways on the right bacteria colonisation in your gut.

Other probiotic capsules, for example, give anti-ageing effects or are used to regulate vaginal flora as well as promoting weight loss. Probiotic capsules are also said to be effective for certain other diseases such as mental illnesses, obesity or the prevention of allergies.

By taking probiotic capsules, the intestinal walls are colonised with good bacteria, while bad bacteria and certain toxins become impermeable. Good bacteria in the gut are important so that your body can better absorb nutrients, vitamins and minerals that are absorbed through food intake.

How much do probiotic capsules cost?

If you take probiotic capsules regularly, the whole thing will be expensive. Before buying, be aware that you are investing your money well. It is best to consult your family doctor.

What are the alternatives to probiotic capsules?

There are four alternatives: Probiotics in powder form, in liquid form, in tablet form and through natural food intake.

Probiotics in food

If you have problems with your intestinal flora, you don't necessarily have to take supplements. In some cases, increasing your intake of probiotic foods can help get your gastrointestinal tract back on track.

Probiotics in powder form

Powdered capsules are very easy to dose individually. They contain significantly fewer fillers and are super suitable for babies and children.

Some people also have a problem swallowing their tablet or capsule. For this reason, it is recommended that you take probiotics in powder form, as it can also be mixed with food, for example, and then taken without any problems. The big disadvantage here is that you do not have a guaranteed stomach acid resistance.

Probiotics in liquid form

Probiotics in liquid form can often contain fermented fruit, herb or medicinal plant extracts in addition to microorganisms. These substances can help to positively influence the intestine so that "bad" bacteria and e.g. fungi are killed.

According to studies, the best results are achieved when probiotics in liquid form are mixed with capsules.

Probiotics in tablet form

Probiotics in tablet form often result in a reduced effect of the probiotics because it is difficult to ensure the survival of the bacteria.

It often happens that probiotic bacteria in the tablet are not well absorbed and thus many bacteria are lost. The tablets are nevertheless easy to swallow due to their small size, are cheaper and have a long shelf life.

Decision: What types of probiotic capsules are there and which one is right for you?

Basically, probiotic capsules can be divided into three different types:

  • Capsule shells made of hard gelatine
  • Capsule shells with soft gelatine
  • Capsule shells for vegetarians and vegans

What distinguishes hard gelatine probiotic capsules and what are their advantages and disadvantages?

Probiotic capsules made of hard gelatine (also called hard capsules) consist of a gelatine mass. The capsules feel as if they are surrounded by plastic. As soon as they come into contact with a little water, for example, you may notice that they become slightly greasy or that they dissolve.

Gelatine basically consists of tasteless protein that is taken from "collagen" of the connective tissue of, for example, cattle, poultry, pigs or fish.

Hard gelatine capsules come in different sizes and varieties. There are transparent, opaque, opened and closed capsules. To ensure that they contain mechanical stability, they are closed by the groove-cam mechanism.

For diabetics: Hard capsules made of gelatine are almost calorie-free and have no carbohydrates.

  • Tasteless
  • Low in calories
  • Not suitable for vegetarians and vegans

What are the advantages and disadvantages of soft gelatine probiotic capsules?

Probiotic capsules made from soft gelatine (or soft capsules) come in different forms. In contrast to hard gelatine capsules, soft capsules have a thicker or more elastic and soft shell. They are preferably taken for the absorption of liquid contents, such as oils.

The coating consists of an enteric substance, whereby the contents are then gradually released in the intestine.

  • Harmless despite plasticiser substances
  • Achieves the same effect
  • Easier to take
  • Not suitable for vegetarians and vegans

What are the advantages and disadvantages of probiotic capsules for vegetarians and vegans?

Of course, there are also probiotic capsules for those who do not want animal additives. The vegetarian capsules are also called methylcellulose capsules and consist of a vegetable thickener (vegicaps).

Vegetarian and vegan capsules come in different forms. Almost all of them are lactose-free, gluten-free and wheat-free.

  • Without animal additives
  • gelatine-free
  • Lower tolerance

Buying criteria: You can use these factors to compare and evaluate probiotic capsules

In the following we would like to show you which factors you can use to compare and evaluate probiotic capsules. This will make it easier for you to decide whether a particular preparation is suitable for you.

The following factors should be taken into consideration:

  • Probiotic microorganisms
  • The number of culture forming units (CFU)
  • The ingredients and tolerability
  • The shelf life

In the following paragraphs you can read in detail what the individual purchase criteria are and how they should be classified.

Probiotic microorganisms

In the human intestine there are trillions of microorganisms (or bacteria), the so-called intestinal flora. The microorganisms protect our intestinal mucosa. Probiotic microorganisms in capsules are therefore specially produced bacteria that can eliminate negative germs in the intestine.

Suitable probiotics are characterised by a high bacterial count (e.g. 1 billion/g) and a mixture of different strains.

The vast majority of probiotic preparations on the food supplement market contain various mixtures of the genera lactobacteria and bifidobacteria, sometimes supplemented by Streptococcus and Enterococcus bacteria.

The number of culture-forming units (CFUs)

The number of culture forming units (CFU) tells you how many billions of bacteria are in each capsule. If you take a probiotic capsule with a high number of CFU, they can multiply correspondingly faster.

However, it should be noted that too many CFEs can have a negative effect on the intestinal flora. It is best to consult your family doctor to be sure.

Ingredients and tolerability

Probiotic capsules usually contain the following ingredients:

  • ISOs (isomaltooligosaccharides)
  • MOS (Mannanoligosaccharides)
  • FOS (fructooligosaccharides)
  • Potato starch

ISOs are wheat-based, so probiotics with this filler are not suitable for people with wheat and gluten allergies.

Even if you are not allergic to any of these additives, you may still have an overreaction due to the high intrinsic sugar content. This is because the prebiotics mentioned above are only tolerated by your intestines for a short period of time in low doses.

The fact is that both the "good" and the "bad" bacteria feed on prebiotics. If you take synthetic prebiotics over a longer period of time, this can lead to a new imbalance in your intestinal flora. Especially the growth of the Candida fungus is enormously favoured by sugar.

Shelf life

Probiotic microorganisms are living bacteria that depend on certain conditions to survive or remain viable. If they are exposed to excessive heat or moisture, they die very quickly.

Especially if you buy large quantities of probiotic capsules at once, shelf life is a crucial factor. (Image source: / Benedikt Geyer)

For this reason, probiotic capsules should always be stored in a cool, dry place. This does not necessarily mean that storage in the refrigerator is always necessary.

If the manufacturer does not state otherwise, storage in a place without direct sunlight, heat or moisture is completely sufficient.

Facts worth knowing about probiotic capsules

Taking probiotic capsules in conjunction with antibiotics

Antibiotics have a bactericidal property and kill all disease-causing germs, but unfortunately also the "good" intestinal bacteria. For this reason, antibiotics seriously disturb the balance of your gut.

It takes a long time for your intestinal flora to settle down again. During this regeneration phase, side effects such as diarrhoea or abdominal pain can occur.

It is even advisable to take probiotic capsules at the same time as antibiotics, because this prevents the unpleasant side effects and also that your intestinal flora becomes unbalanced.

Can infants and children take probiotic capsules without hesitation?

In principle, infants and children can also take probiotic capsules without any problems, as long as the child is healthy.

However, please always consult your paediatrician if you are not sure, as probiotic capsules can also be potentially dangerous.

Do probiotic capsules help with weight loss?

Yes, probiotic capsules can theoretically help you lose weight. Most overweight people and diabetics have a disturbed intestinal flora. Therefore, it is also very useful for weight loss to take probiotic capsules.

However, probiotic capsules should not be a panacea for weight loss, but should ensure a healthy gastrointestinal flora. In addition to taking probiotic supplements, a healthy, varied diet and exercise are also helpful for a healthy life.

Can I take probiotics during pregnancy and breastfeeding?

Yes, according to studies, women can take probiotic capsules during pregnancy and breastfeeding without any problems. However, you should always consult your family doctor before taking them.

However, it is considered safe to take probiotic preparations during pregnancy and breastfeeding.

Can I also give my animals probiotic capsules?

Yes, probiotic capsules are also used in the treatment of diseases in dogs, for example. It is advisable to consult a veterinarian.

For a dog, for example, we recommend combining powder and capsule form. For example, you can administer the probiotic in capsule form in the morning and the liquid version in the evening. This helps to ensure the correct dosage.

Probiotic preparations should always be taken in small doses, otherwise they overload the intestines. Here, too, there are often "initial aggravations" such as soft faeces, mucus formation or flatulence. This is completely normal and should subside in 2-3 days.

How can I support my intestinal flora while taking antibiotics?

We recommend that you take probiotic capsules while taking antibiotics, as probiotic capsules help you to keep your gastrointestinal flora in balance.

However, here are some other alternatives you can use:

  • Apple cider vinegar (only natural, unpasteurised)
  • Artichokes
  • Chicory
  • boiled potatoes, eaten cold (e.g. as potato salad)
  • Yoghurt
  • Leek
  • Miso paste (stir into a soup or sauce for seasoning, do not bring to the boil)
  • Parsnips
  • Rice, eaten cold
  • raw sauerkraut
  • Black salsify
  • Soy sauce (only the organic variety, i.e. shoyu or tamari)
  • Umeboshi plum

Can I also take expired probiotic capsules?

In principle, you can also take expired probiotic capsules. Strictly speaking, there is no "expiry date" for medicines and probiotics. The only thing that cannot be guaranteed after the expiry date is whether the preparations have the same effect.

Probiotic capsules contain many living microorganisms and must therefore be stored in the refrigerator. They lose their complete effect three months after the expiry date at the latest.
