"Premium pricing justified by clinical backing"
Both strains are commodity ingredients available generically for £0.15-0.30 per dose; this product costs £1.16-2.32 per capsule.

Consumer advice
- • If you have IBS symptoms, this product has legitimate clinical backing for the two strains it contains. However, before buying at this price point:.
- • Check if generic L. reuteri DSM 17938 or ATCC PTA 6475 supplements are available at 1/5 the cost — they contain the same active ingredients.
- • Confirm you actually have IBS (not just occasional bloating) — the evidence is strongest for diagnosed IBS, not general gut discomfort.
- • Give it 4-8 weeks of consistent use; probiotics don't work overnight.
