What are probiotics?

The definition of aprobiotic is simple: it is a live microorganism. This beneficial bacterium , chosen according to its strain, offers a targeted benefit to your health by acting directly on the balance of your microbiota.

Definition: What is a probiotic?

To understand what a probiotic is, there's nothing better than referring to the official definition from the World Health Organization (WHO) . It describes them as:

“ Live microorganisms which, when administered in adequate amounts, confer a health benefit on the host. ”

Specifically, we're talking about "good" bacteria and certain yeasts. The key word is "alive": to be active, a probiotic must arrive alive in your digestive system. The "host" is simply you!

These microorganisms, such as the well-known Lactobacillus and Bifidobacterium families, lend a hand to your microbiota . Each strain has its own specific characteristics, which makes this world so rich and interesting for your well-being.

Probiotics vs Prebiotics: Don't make the mistake again!

They are often confused, but their role is completely different . To put it simply, imagine that your gut flora is a garden.

Probiotics are the seeds you add. They are the new beneficial bacteria or yeasts that enrich the diversity of your microbiota .

Prebiotics, on the other hand, are like fertilizer . They are specific dietary fibers that you don't digest, but which serve as the exclusive food for the good bacteria already present, stimulating their growth.

These two elements therefore work in perfect synergy . To learn more, check out our article on the link between probiotics and prebiotics .

Probiotics: who are they really useful for?

Probiotics are suitable for anyone wishing to support their digestive and immune balance on a daily basis.

They are particularly recommended if your gut is sensitive, after antibiotic treatment, or as a preventative measure during periods of stress or travel.

They are suitable for both adults and children , provided that strains and dosages are chosen that are appropriate for each situation.

While probiotics can be beneficial for everyone, certain situations and profiles benefit more directly. Everyone is different , but you might recognize yourself in one of these cases.

Here are some examples of profiles for whom probiotic support is particularly beneficial:

People with sensitive digestive systems

For you, even the slightest slip-up or stress can affect your well-being. Symptoms like bloating or irregular bowel movements can be signs of an imbalanced gut flora. Targeted supplementation can help maintain your gut's balance.

Those who are undergoing antibiotic treatment

An antibiotic is designed to fight a bacterial infection , but it doesn't distinguish between good and bad bacteria. Supporting your gut microbiota during and after treatment is an excellent approach to minimizing discomfort .

Athletes and travelers

Intense exertion or a change in environment (diet, hygiene) poses challenges for the body. Strengthening the immune and digestive systems beforehand allows you to approach these periods with greater peace of mind and better manage any unforeseen situation.

Women who are mindful of their balance

The female flora is a delicate ecosystem. Certain strains of probiotics taken orally are known for their ability to support the balance of this area , which is particularly sensitive to variations.

This is the case with our Intimate Flora Probiotics formula.

Parents for their child

A child's immune system and digestive ecosystem are still developing. To help with a temporary ailment or to support their natural defenses , there are probiotic formulas specifically adapted for young children.

Why take probiotics?

The main benefit of probiotics is to support and enrich your gut microbiota . This complex ecosystem plays a much larger role than you might imagine. Here are the concrete benefits they can provide.

1. Improve digestive comfort

This is their most well-known effect . Certain strains have demonstrated their effectiveness in helping to regulate digestion and reduce discomfort such as bloating. Good digestion is the foundation of overall well-being.

2. Participate in natural defenses

Did you know that nearly 70% of our immune cells reside in our gut? By taking care of your gut microbiota, you directly support your body's first line of defense. It's an excellent preventative measure.

3. Aid in recovery after antibiotic treatment

Antibiotics can cause temporary dysbiosis . The main drawback is the risk of diarrhea. A study ( Cochrane meta-analysis, 2017 ) suggests that the use of probiotics is a strategy with real potential to prevent this symptom .

4. Supporting the balance of the skin and vaginal flora

The gut-skin axis is now well-documented. A balanced microbiota has a positive effect on skin quality . Similarly, certain species taken orally help maintain a healthy balance of the vaginal flora.

5. Potential for mood balance

This is the most fascinating field of study. The gut-brain axis shows how our gut communicates with our head . Specific strains, called psychobiotics , have the potential to help us better manage stress and mood.

Where can I find probiotics?

You can enrich your gut microbiota in two complementary ways: through what you eat or with targeted support . One doesn't exclude the other; it all depends on your goal!

Natural probiotics in your diet

Your plate is the primary source of beneficial bacteria . Regularly consuming foods rich in lactic acid bacteria is a simple and effective habit. Consider, for example:

• Dairy products such as quality yogurts, milk kefir or fermented milk.
• With lacto-fermented vegetables such as raw sauerkraut or kimchi.
• To drinks like kombucha or fruit kefir .
• To certain soy-based products (miso, tempeh).

This supplement is perfect for maintenance . The main point to note is that the quantity and variety of active strains in each food are not guaranteed.

Choosing dietary supplements: precision and effectiveness

For targeted action or a course of treatment , turning to a supplement is a relevant approach. Their main advantage is precision. Each product contains strains of bacteria or yeasts selected for their beneficial properties , and in controlled quantities.

The form (capsule, powder, drops, etc.) is designed to protect the microorganisms from stomach acid, ensuring their safe arrival in the intestine. This guarantees that the indicated dose is precisely the one that will be available to your gut microbiota.

How to choose the right probiotic supplements?

Choosing the right probiotic may seem complex, but it's not if you know which criteria to consider . The quality and effectiveness of your treatment depend on a few key points, which comply with specific regulations for your safety.

Criteria for avoiding mistakes

To choose a probiotic , 3 criteria are key:

The strain is paramount: There are many types of probiotics. Look beyond the genus (e.g., Lactobacillus ) to find the specific strain (e.g., rhamnosus GG ). Each strain has its own unique characteristics and documented properties . The right choice depends on your initial needs.

To learn more, we refer you to our guide on the best probiotic strains .

The CFU count: The CFU (Colony Forming Unit) indicates the quantity of live microorganisms. An effective dosage is measured in billions . A high number is not always synonymous with better quality; the most important factor is the suitability of the chosen strain.

Quality of protection: Gastro-resistant capsules are an important criterion. They ensure the survival of the bacteria during their passage through the stomach, thus guaranteeing their effectiveness once they reach the intestine.

Practical questions about your treatment

When should I take my probiotics?

The ideal time is in the morning, about 20 minutes before breakfast , or in the evening at bedtime, away from meals.

How long does it take to feel an effect?

The effect on digestive comfort can be felt after a few days. For a lasting benefit, it is generally necessary to wait 2 to 3 weeks .

What is the ideal duration of a treatment?

A duration of 1 to 3 months is recommended to allow the strains time to establish themselves properly. This treatment can be repeated several times a year if needed.

Can it be taken every day?

Yes, it is perfectly possible to take probiotics continuously , respecting the dosage recommended on the product.

Are there any side effects?

At the start of treatment, mild digestive discomfort (gas) may occur , a sign that your gut microbiota is rebalancing. This effect is temporary. If you have any health problems or are immunocompromised, consult your doctor.

What is the price of a probiotic supplement?

The price of a probiotic can vary enormously depending on the quality, the number of strains, the concentration in CFU (colony forming units), and the dosage form (capsules, sachets, ampoules…).

In our opinion, the average price for a box of 60 probiotic capsules is around €20 . Note that there is no reimbursement from Social Security .

When should probiotics be used for optimal effect?

There's no single best time to take probiotics. Their use depends entirely on your goal and situation. Whether for targeted action or long-term support, here are the contexts in which their use is most relevant.

After a course of antibiotics

An antibiotic is designed to eliminate bad bacteria, but it also affects good bacteria . Numerous studies have examined this issue. To limit this impact on your gut microbiota, it is advisable to start a course of probiotics at the same time as your antibiotic treatment (separating doses by 2-3 hours) and to continue it for a few weeks after finishing. If in doubt, consult your doctor .

As a preventative measure: anticipating the challenges

Sometimes, the best approach is to anticipate. You can prepare your body in advance of an event that could disrupt your balance:

• Before a trip: To get your digestive system used to a change in diet and environment.
• During seasonal changes: To support your natural defenses when your body is under more stress.
• During a period of stress: Since the gut and the brain are linked, stress has a direct impact on your digestive comfort.

For regular or occasional treatment

You don't need a specific reason to take care of your gut microbiota. A 1- to 3-month course, once or twice a year, is an excellent way to maintain balance .

This is suitable for everyone , and there are even specific formulas if you're looking for a probiotic for an infant, for example. These treatments contain strains chosen for daily maintenance.

In summary, a probiotic is much more than just a "good bacterium": it's a precision tool for your well-being . You now know that its effectiveness is based on clear criteria: choosing the right strain for the right need, an appropriate dosage in billions of CFU, and effective protection all the way to the gut.

Armed with this knowledge, you have all the tools you need to make an informed choice and actively take care of your inner balance.
