Take 2 capsules daily during and for a few days after antibiotic treatment. Can be taken at the same time as antibiotics. Swallow with a cold or lukewarm drink. Store in a cool, dry place. No refrigeration required.
Antibiotics are an essential tool in modern medicine, but they come with a well-known side effect: disruption to the gut microbiome. As antibiotics work to eliminate harmful bacteria, they inevitably affect the beneficial bacteria in the gut too - leading to digestive upset, bloating, loose stools, and an increased risk of opportunistic infections like Clostridioides difficile. Optibac Probiotics For Those on Antibiotics is specifically designed to address this problem, providing robust probiotic support during and after antibiotic treatment.
What makes this product stand out is its use of Saccharomyces boulardii - a probiotic yeast, not a bacterium - as its primary active strain. Because it is a yeast rather than a bacterium, S. boulardii is not affected by antibiotics in the same way that bacterial strains are. This means it can be taken alongside antibiotics without being destroyed by them, making it uniquely suited to this specific use case.
Saccharomyces boulardii is one of the most extensively researched probiotic organisms in the world, with hundreds of clinical studies examining its effects on antibiotic-associated diarrhoea, C. difficile infection, traveller's diarrhoea, and more. It works by maintaining the integrity of the gut lining, modulating the immune response, and producing enzymes that help neutralise certain bacterial toxins. When taken during antibiotic treatment, it has been shown in multiple trials to significantly reduce the incidence and severity of antibiotic-associated diarrhoea.
The 10-capsule pack is sized to cover a standard 5-7 day antibiotic course, with a recommended dose of 2 capsules per day. Capsules can be taken at the same time as antibiotics - no need to space them out - which simplifies the routine considerably. Continue taking the capsules for a few days after finishing the antibiotic course to help support gut recovery.
Optibac For Those on Antibiotics is free from gluten, dairy, and soya. It is suitable for vegetarians. The formula is straightforward and contains no artificial fillers or preservatives. As with all Optibac products, the strain is fully identified, the dose is stated clearly, and the research behind the formulation is publicly available.
If you've ever suffered through the digestive misery that can follow a course of antibiotics, this product offers a practical, evidence-based solution. Many GPs, pharmacists, and nutritional therapists recommend taking a probiotic alongside antibiotic treatment as standard practice. Optibac For Those on Antibiotics makes that recommendation easy to act on - with a product that's been purpose-built for exactly this situation. Keep a pack on hand whenever a prescription is issued, and protect your gut through every course of treatment.
