What probiotics are

Probiotics are dietary supplements that provide beneficial live microorganisms, mainly strains of bacteria and yeasts, designed to support the balance of the gut microbiota. Within nutricosmetics they have become common due to the relationship between the state of the digestive system and the appearance of the skin, although their main function remains to support the overall wellbeing of the body. They come in capsules, sachets or tablets, and are understood as a complement within a varied and balanced diet, never as a substitute for a regular diet.

How to choose probiotics based on your goal

There are many different probiotic strains, each with a different role, so it is worth paying attention to the specific composition of the product before choosing.

  • General digestive balance: broad-spectrum multi-strain formulas.
  • Support for the appearance of the skin: specific strains sometimes combined with prebiotics.
  • Occasional use: formulas with fewer strains for specific periods.
  • Ongoing use: formulas designed to be taken over longer cycles.

The number of strains is not the only relevant factor: the number of colony-forming units per dose also influences the formula chosen.

Probiotics and prebiotics: what's the difference

Probiotics are the live microorganisms themselves, while prebiotics are fibers that serve as food for those microorganisms and promote their growth. Many formulas combine both in a single product, known as a symbiotic, seeking a complementary effect. When choosing a product, it is worth checking whether it is a simple probiotic, a prebiotic, or a combination of the two, since each type serves a different function within the formula.

What to look for on a probiotic label

It is important to check the number and name of the strains included, as well as the number of colony-forming units guaranteed up to the expiry date, not just at the time of manufacture. It is also worth checking the storage conditions, since some formulas need to be kept cold or protected from moisture to keep the microorganisms alive until they are taken. Finally, checking whether the packaging indicates resistance to gastric acidity helps determine whether the strains are designed to reach the intestine active.

How to take probiotics

The dosage guidelines vary depending on the formula and manufacturer, although it's usually recommended to take them once a day, often with a meal to help them pass through the digestive system. It's a good idea to keep taking them for the period indicated on the packaging, as the effects on digestive balance aren't immediate. Pregnant or breastfeeding individuals, or those with a weakened immune system, should consult a healthcare professional before taking probiotics.

Common mistakes when taking probiotics

A common mistake is stopping after just a few days because no immediate changes are noticed, when the effect on digestive balance is usually seen gradually after several weeks of continuous use. Another mistake is not checking the storage conditions indicated by the manufacturer, which can reduce the viability of the microorganisms before they're taken. It's also worth remembering that probiotics complement a varied, fibre-rich diet, but don't replace it.

Probiotics as part of a wellness routine

The balance of the microbiota depends on many factors besides probiotics, such as a varied diet with fibre, fruits and vegetables, adequate rest and controlled stress levels. That's why probiotics are usually best understood as one piece of a broader wellness routine, rather than an isolated element capable of making up on its own for disorganised habits or a poorly varied diet maintained over time.

Introducing changes gradually, both in your diet and when adding a new probiotic, usually makes it easier for the body to adapt and reduces the mild digestive discomfort that sometimes appears at first. Staying consistent day by day, rather than seeking high doses occasionally, tends to give the best results in the medium term within this category of supplements, both for digestive balance and for the skin's overall appearance over time.
