  • Product Information

  • Acidophilus Extra 4 Billion is one of our top-selling formulas, with each easy-to-swallow capsule delivering 4 billion colony forming units (CFU) of live bacteria. We often recommend our acidophilus capsules to people who want to take a live bacteria product long-term. Acidophilus Extra 4 Billion is also safe for children and can be taken during pregnancy and while breastfeeding.

    Based on science
    Our acidophilus capsules contain strains of live bacteria originally isolated from humans and widely used in clinical studies: Lactobacillus acidophilus and Bifidobacterium. These bacteria are far more at home in our digestive system, adhering to the gut wall where they can colonise, than the live bacteria found in yoghurt. Click here to learn more about the strains we use.

    A survival story
    The low pH level of stomach acid creates a harsh environment for good reason, it helps breakdown food and destroy harmful bacteria, but it can also make the journey for live bacteria a challenge. Research suggests that up to 80% of live bacteria don’t survive gastrointestinal transit. Armed with this knowledge, we've encapsulated Acidophilus Extra 4 Billion in unique delay-release capsules to protect the acid-sensitive bacteria. The sophisticated properties of our acidophilus capsules slow the rate at which they open, ensuring the complete release doesn't occur until 50 minutes after consumption. The capsules' low moisture content further enhances the live bacteria's stability, which means it only releases in the small intestine, where conditions are ideal for growing and replicating.

    A winning format
    We prefer acidophilus capsules because this form preserves the delicate 'live' bacteria. On the other hand, acidophilus tablets are compressed into moulds, which create heat and compromise viability.

    Soluble fibre is often used in combination with live bacteria supplements, as they work harmoniously to support the environment in the gut. Take a look at our natural soluble fibre product, Flourishe®, by clicking here.

    Sophisticated packaging
    Supplementing with acidophilus only works if the bacteria are kept active in a state of 'suspended animation' in other words, they're still viable after swallowing. So we've designed an advanced, high-density, moisture-resistant pot to protect our capsules from moisture and light, which keeps the live bacteria viable in their packaging. That's why we can confidently guarantee a 24-month shelf life at time of packing*.

    To ensure our strict quality standards are always met, we manufacture and package our formula in UK factories working to Good Manufacturing Practice (GMP).

Frequently Asked Questions (3)
Q - "How Should I Store Acidophilus Extra 4 Billion?"
A - Our high performance packaging has been designed with a high-density moisture resistant pot to keep light and moisture away from the capsules. The special desiccant layer locks away moisture which keeps the bacteria viable for 24-months. Acidophilus Extra 4 Billion doesn’t need to be refrigerated. Ensure pot is securely closed after opening.
Q - "What Is The Difference Between Live Cultures Found In Yoghurt And Supplements?"
Live cultures found in yoghurt and supplements differ enormously. Live cultures found in yoghurt have a short shelf life and they’re also tremendously fragile. And so, by the time the yoghurt reaches your bowel, it’s highly likely the live cultures won’t survive the journey to where they’re needed, your gut. Live culture supplements, on the other hand, tend to be encapsulated in sophisticated, moisture-resistant packaging that ensures the bacteria remains active as they traverse down to your digestive tract.
Q - "How Many Acidophilus Capsules Should I Take?"
A - 1-2 capsules daily. Take with a glass of water, ideally first thing in the morning when the pH of the stomach is at its highest (i.e., not so acidic). Do not exceed the recommended daily dose. Do not swallow capsules with hot drinks, as heat kills bacteria. Food supplements should not replace a balanced diet and a healthy lifestyle.
