What's working inside
- Intensive microbiome support — 20 billion CFU of 8 well-studied probiotic strains for deep microbiome reinforcement.
- Acid-resistant delivery — Capsule technology ensures the probiotics survive stomach acid and reach the gut alive.
- Travel & antibiotic ready — Ideal for post-antibiotic recovery, frequent travel, or stubborn digestive concerns.
The Science of Gut Microbiome Balance
Modern life can disrupt your gut microbiome. Stress, processed foods, and travel can all deplete the friendly bacteria your body relies on. 20 Billion CFU delivers a high-strength alternative to standard probiotics to help restore that balance.
We designed this formula for those who need maximum support, focusing heavily on bacterial survival and successful colonisation. Unlike standard probiotics found in supermarket yoghurt drinks, our multi-strain formula is dairy-free, sugar-free, and purposely designed to populate both the upper and lower bowel for complete digestive support.
Whether you are recovering from a course of antibiotics, preparing for travel, or simply looking to optimise your daily digestion, this complex provides robust, reliable microbiome support.
The Microbiome Matrix
We have selected 8 specific strains to colonise the entire intestinal tract:
- Small Intestine Support: Lactobacillus acidophilus, L. casei, L. rhamnosus, and L. bulgaricus are primarily found in the small intestine, where they support digestion and immunity.
- Large Intestine Support: Bifidobacterium breve, B. infantis, and B. longum are key residents of the colon (large intestine), helping to break down complex carbohydrates and maintain regularity.
- Synergistic Action: Streptococcus thermophilus is included to work synergistically with the other bacteria, creating a favourable environment for growth.

How to Use
Take 1 capsule, 1 to 3 times per day with water.
Best practice: Can be taken with food or on an empty stomach. If you have trouble swallowing capsules, you can pull them apart and mix the contents into a cool drink or food (just avoid hot liquids, as heat can damage the live cultures).
Backed by Science & Quality
The effectiveness of a probiotic depends on two things: strain diversity and survival. Explore the clinical data:
- Acid Resistance: Our strains are micro-encapsulated to withstand stomach acidity. Tests show they survive conditions of pH 2.0 for 2 hours, ensuring they reach the colon viable and active.
- Multi-Strain Synergy: Research suggests that multi-strain probiotics are more effective than single-strain products because they can colonise multiple locations in the gut and provide broader protection against harmful micro-organisms.
- Potency Guarantee: Independent laboratory testing confirms the concentration of live bacteria, ensuring you receive the full 20 billion CFU stated on the label.
The Health Improvers Difference:
- Quality assured: UK manufactured to GMP standards.
- Purpose-led: No unnecessary additives; designed for real life, not trends.
- Risk-free: Covered by our 60-day money-back guarantee.

Before you Buy
The questions we hear most — answered straight.
Does this product need to be refrigerated?
No. The bacteria are specially coated during manufacturing to ensure they remain stable at room temperature. This makes them perfect for travel and prevents damage caused by the moisture changes in a fridge.
Will the bacteria survive stomach acid?
Yes. All 8 strains are micro-encapsulated to withstand stomach acidity. Laboratory tests show they survive pH 2.0 conditions for 2 hours, ensuring they reach your intestines in a viable state.
Why take 20 billion instead of a lower dose?
A higher strength formula is often recommended for those who have recently taken antibiotics, have a specific digestive concern, or simply want a more robust daily support to ensure rapid colonisation.
Can I open the capsule if I can't swallow it?
Yes. You can pull the capsule apart and mix the contents into a cold drink or food. As long as it is consumed within 12 hours, the probiotics will remain effective.
Is this product Vegan?
Yes. The product contains no dairy or animal derivatives and uses a vegetable cellulose capsule, making it 100% suitable for vegans and vegetarians.
