How do you choose a probiotic for your patient?
Faced with a plethora of products on the market, it's not always easy for health professionals to suggest a product containing one or more high-quality probiotic strains adapted to the needs of their patients 1,2 . Recommendations from experts can make this easier.
About this article
Advising a patient to "take probiotics" is not necessarily sufficient for a patient looking for a probiotic for a specific disorder 3. However, an American study found that 40% of primary care professionals who recommend probiotics to their patients let them choose their own product 4. Although it is now generally accepted that probiotics contribute to healthy gut microbiota, experts agree that the vast majority of probiotic effects are strain-dependent 5,6.
It is therefore important to ensure that the strain is effective in terms of the targeted health need or disease 7. To do this, it is necessary to check that the product characteristics and information (strain, dosage, formulation) match in every respect those used in the clinical trials that proved the benefit ascribed to the product 3. As such, particular attention should be paid to the following:
- clear reference to the genus, species and probiotic strain contained in the product and the associated indication 8,9 ;
- product dosage 3,8 ;
- clinical proof of the efficacy of the probiotic strain in the therapeutic area with which it is associated. at a dosage similar to and not lower than the one used in the clinical trial 8.
Other factors should also be taken into account when choosing a probiotic, such as :
- formulation type 3,8 ;
- remaining viability up to the expiration date, not from the date of manufacture 8;
- product quality resulting from manufacturer requirements, i.e., quality controls and, preferably, certification by an independent body 8,9 .

Contraindications and potential side effects :
Patients should be informed that taking a probiotic-based product orally may be accompanied by transient side effects such as gas and bloating 10.
It is important to bear in mind and inform the patient that the efficacy of a probiotic strain may vary from one patient to another 3.
Although the risks associated with probiotic strains are acknowledged to be low, it is prudent to avoid prescribing probiotics to premature newborns, people who are intolerant to any of the excipients used in the formulation of probiotic-based products, immunosuppressed patients, people with short bowel syndrome or those in critical condition 3,11,12.
