Optibac Probiotics Bifido & Fibre

Your gut takes a beating during heavy training. High-carb fueling, training stress, travel, and back-to-back sessions all disrupt the balance of bacteria in your digestive tract — and when your gut is off, everything else follows: bloating, irregular digestion, compromised nutrient absorption. Optibac Bifido & Fibre gives your gut the targeted support it needs to stay consistent, so the nutrition you're putting in actually works for you.

Each sachet delivers 25 billion live cultures of Bifidobacterium lactis BB-12® — the world's most researched strain of the entire Bifidobacteria family — combined with 4g of prebiotic FOS fiber that feeds and grows your natural gut bacteria from the inside out. This isn't a generic probiotic. It's a precision-formulated synbiotic that works on two levels simultaneously.

Clinically Researched Strain – BB-12® is one of the most studied probiotic strains in existence, with thousands of participants across gold-standard clinical trials. It's been shown to survive stomach acid and reach the gut alive, where it complements and supports your existing gut bacteria.

Prebiotic Fiber That Feeds the Good Stuff – The 4g of FOS (fructooligosaccharides) in each sachet acts as food for beneficial gut bacteria, particularly Bifidobacteria. This prebiotic component actively increases the levels of good bacteria already present in your gut — not just adding new ones, but growing what you already have.

Supports Regularity and Immune Function – Consistent gut bacteria balance supports healthy, regular digestion. BB-12® has also been shown in research to stimulate immune responses including immunoglobulins — important for athletes whose immune systems are regularly challenged by training load.

The synbiotic combination of probiotic and prebiotic in one sachet meets the International Scientific Association of Probiotics & Prebiotics' recommended daily intake of 3–5g of fermentable fibers. One sachet covers it. No refrigeration needed, no artificial flavors or colors, no dependency. Just clean, effective gut support in a format you can take anywhere — mix it into water, a smoothie, or any cool non-acidic food.

Consistent gut health is one of the most underrated performance variables in endurance sport. When your digestive system runs smoothly, you absorb more from your nutrition, recover faster, and spend less energy managing GI distress. Optibac Bifido & Fibre is the daily foundation that keeps everything else working.

How to Use Optibac Probiotics Bifido & Fibre

Daily Use: Take 1 sachet per day mixed into cool, non-acidic food or drink — water, a smoothie, or yogurt all work well. Avoid hot liquids, which can damage live cultures.

Initial Phase: Up to 4 sachets daily may be taken during the initial adjustment period if targeting specific digestive concerns. Scale back to 1 per day once regularity is established.

Pro Tip: Take with food rather than on an empty stomach to help the cultures survive transit and reach the gut alive. Consistency matters more than timing — pick a daily routine and stick with it.

Note: Some users experience temporary flatulence during the first few days as the gut adjusts to the FOS fiber. This is normal and typically resolves within 3–4 days.
