#Probiotics

Strain-specific probiotic evidence — L. rhamnosus GG, S. boulardii and more. AAD use, immune-claims caution, paediatric and immunocompromised safety.

Probiotics are live microorganisms that, when given in adequate amounts, confer a health benefit (ISAPP 2014 consensus). Clinical effects are strain-specific — there is no "probiotic effect" that generalises across all products on the shelf.

Best-evidence strains. Lactobacillus rhamnosus GG and Saccharomyces boulardii have the strongest evidence for antibiotic-associated diarrhoea (Cochrane reviews report relative risk reductions around 0.46, with a number-needed-to-treat near 9). For functional GI conditions, Bifidobacterium infantis 35624 and certain multi-strain formulas show modest IBS-symptom benefit.

Doses. Expressed in colony-forming units (CFU). Most clinical trials use 1-50 billion CFU/day. Higher does not necessarily equal better — strain identity and viability through the GI tract matter more than headline numbers.

Immune claims — caution. Routine "boosts immunity" framing is structure-function language that exceeds the evidence base. Refrigerated, shelf-stable and freeze-dried products differ in viability.

Safety — immunocompromised contraindication. Probiotics should not be used outside clinical supervision by immunocompromised patients, premature infants in NICU settings, or people with central venous catheters. Case reports of fungaemia (S. boulardii) and bacteraemia exist for these populations.

On HealthyHerbology we cover probiotics across paediatric strain-selection and safety, women's gut-skin and antibiotic-recovery contexts, and digestive-health supplementation.

Frequently asked about Probiotics

Are all probiotic strains the same?
No. Clinical effects are strain-specific. For example, Lactobacillus rhamnosus GG and Saccharomyces boulardii have the strongest evidence for antibiotic-associated diarrhoea — other strains have not been shown to do the same.
When should I take probiotics?
Most products are best taken with or just before a meal. If taking alongside antibiotics, separate the doses by at least 2 hours to maximise survival of the probiotic strain.
Who should not take probiotics?
Immunocompromised patients, premature infants in NICU settings and people with central venous catheters should not take probiotics outside of clinical supervision — case reports of sepsis and fungaemia exist for some strains.
