Probiotics: how do you choose a supplement to suit your needs?

Probiotics appeal to many consumers in France, whether they’re looking to support digestive comfort, adjust to a change in diet or find a supplement suitable for a child or a pet. But choosing the right product involves more than comparing the number on the bottle.

A suitable formula should be assessed against several factors: the strain, the quantity actually stated, the format, storage requirements and the needs of the person — or animal — it’s intended for. Here’s what to check before buying a probiotic supplement, along with a selection of products available at Joybuy.

Common pitfalls when buying probiotics

1. Focusing only on the billions

A high CFU count — CFU stands for colony-forming units — isn’t enough to determine whether a product is right for you. A formula containing 60 billion CFU won’t necessarily serve the same purpose as a supplement containing a single targeted strain.

Always check:

  • the full name of the strain, not just the species;
  • the amount per daily serving, rather than per capsule;
  • whether it contains prebiotics, vitamins or other complementary ingredients;
  • the best-before date and storage instructions.

2. Confusing lactic acid bacteria with live probiotics

Some products contain heat-treated or inactivated lactic acid bacteria. These aren’t the same as a formula made with live micro-organisms. For example, the ORIHIRO supplement states that each serving contains 1.5 billion heat-treated lactic acid bacteria of plant origin, along with calcium, vitamin D and magnesium.

That isn’t necessarily a drawback. This information simply helps you understand what you’re buying and avoid comparing two products based only on the number shown on the packaging.

3. Overlooking storage requirements

Heat, moisture and light can affect the stability of some cultures. A formula that needs to be refrigerated after opening may not be practical if you travel often or simply want to keep the bottle in a cupboard.

Read the instructions before placing your order and follow the manufacturer’s recommendations. Probiotic gummies, in particular, can be sensitive to heat and moisture.

Technical factors to compare

The strain and what you’re looking for

Formulas combining Lactobacillus and Bifidobacterium are common for digestive comfort. However, probiotics for the gut microbiome shouldn’t be chosen solely on the basis of their bacterial family. The specific strain, dosage and recommended duration are all important when comparing products.

If you have a particular need, look for a formula with a clearly stated purpose:

  • gut microbiome and digestion: multiple strains or a strain documented on the label;
  • probiotics for children: minimum age, choking risk and adult supervision;
  • anti-stress probiotics: whether magnesium is included and any age restrictions;
  • probiotics for intimate flora: a formula intended for adults or teenagers, as stated on the label;
  • probiotics for clear skin: whether zinc or other ingredients are included;
  • probiotics for dogs and cats: a dose suited to the animal, how to give it and which species it’s intended for.

Health claims aren’t a guarantee that a product will have the same effect for everyone. If you’re taking medication, are pregnant or breastfeeding, have a medical condition or have a weakened immune system, ask a healthcare professional for advice.

Format and daily dose

Probiotic capsules make it easy to take a precise dose. Gummies are easier for some children to chew, but they may contain sugar or glucose syrup. Powders and sachets can be mixed straight into food, which may be convenient for pets.

Check how many doses you need to take each day and how many days the bottle will last. A bottle of 60 capsules won’t necessarily last 60 days: some formulas recommend taking two capsules a day.

Tolerance and complementary ingredients

Prebiotics such as inulin, FOS or acacia fibre provide a food source for certain bacteria. However, some people may temporarily experience bloating or tummy rumbling. Follow the label instructions and stop taking the product if discomfort persists.

Also check the list of allergens, sweeteners and any milk, soya or gluten, as well as whether the product is suitable for a vegetarian or vegan diet.

Frequently asked questions about probiotics

How long should you take probiotics for?

It depends on the formula and the recommendations on the label. Some products are intended to be taken for one to three months, while others are designed for daily use. Don’t extend a course without a specific reason, and ask for advice if your symptoms persist.

Can you take probiotics with antibiotics?

Several manufacturers recommend leaving two to three hours between doses. This guidance may vary by product, so check the instructions and ask your pharmacist or doctor for advice.

Do probiotics need to be kept in the fridge?

Not necessarily. Some capsules can be stored at room temperature, while others — including some multi-strain formulas — need to be refrigerated after opening. Always follow the instructions and product label.
