Probiotics: How to Choose the Right Ones for Digestion and Immunity

Faced with digestive problems (bloating, irregular transit, weakened immunity), probiotics have become a common health reflex. But not all strains are equal: effectiveness, CFU dosage, resistance to gastric acidity... here's how to choose a probiotic according to scientific literature, and the options actually available on Pharmaplusfrance.store.

What is a probiotic?

Probiotics are living microorganisms (bacteria or yeasts) which, when administered in sufficient quantities, can have a beneficial effect on the host's health, particularly on digestion [1].

Criteria for a good probiotic

• CFU count (Colony Forming Units): dosages studied generally vary between 1 and 25 billion CFU per day depending on the strain and indication [2].
• Documented strains: Lactobacillus rhamnosus, Saccharomyces boulardii, Bifidobacterium lactis are among the most studied strains [3].
• Gastric resistance: gastro-resistant capsules aim to protect bacteria from stomach acid [4].
• Storage: some strains require refrigeration, others are stable at room temperature — check manufacturer's instructions.

For what indications?

• After antibiotic treatment: to support the balance of intestinal flora [5]
• Irritable bowel syndrome: some strains are studied for their effect on bloating [3]
• Daily digestive comfort: transit, digestion, bloating

How to take them correctly?

• Preferably take on an empty stomach or before a meal depending on the strain
• Follow a course of treatment for at least 2 to 4 weeks
• Avoid combining them with very hot drinks
• Repeat the course after antibiotic treatment or a change of season
