20 Billion CFU | High Strength 8-Strain Live Culture Capsules | Vegan, UK-Made

The same eight strains as our standard pot, at five times the count.

What's actually in the capsule

  • 20 billion viable organisms per capsule — the figure on the label, not an "up to".
  • 8 named strainsLactobacillus rhamnosus, L. casei, L. acidophilus, L. bulgaricus, Bifidobacterium infantis, B. breve, B. longum and Streptococcus thermophilus. Every one named on the pack.
  • Bile and acid tolerant strains — selected for their tolerance of stomach acid and bile salts.
  • No refrigeration — keep it in a cupboard, take it away with you.
  • Vegan HPMC capsule — no gelatine, no dairy, no bulking agent. This one is the strains and the capsule, nothing else.

Which pot should you buy?

Our 4 Billion CFU pot has exactly the same eight strains at a lower count and a lower price. This one has five times the organisms per capsule. We are not going to tell you that five times the count does five times anything — live cultures carry no authorised health claims in Great Britain, so nobody can honestly tell you that. What we can tell you is the count, the strains, and the price, and let you choose.

We make it here in the UK in a GMP-certified facility, and it's covered by our 60-day money-back guarantee, even if the bottle is half empty.

Ingredients

Each capsule provides 20 billion viable organisms from a bio-live bacteria blend of eight strains:

  • Lactobacillus rhamnosus
  • Lactobacillus casei
  • Lactobacillus acidophilus
  • Lactobacillus bulgaricus
  • Bifidobacterium infantis
  • Bifidobacterium breve
  • Bifidobacterium longum
  • Streptococcus thermophilus

Full ingredients: Stabiliser: Hydroxypropyl Methylcellulose; Capsule Shell: Hydroxypropyl Methylcellulose (HPMC); Bio-Live Bacteria Blend (the eight strains listed above).

That's the complete list. Unlike our 4 Billion pot, there is no brown rice flour carrier in this one — it is the strains and the capsule shell, nothing else.

Food supplement suitable for vegans. No dairy, no gelatine. 30 capsules per pot. Made in the United Kingdom in a GMP-certified facility.

Storage: No refrigeration required. Store in a cool, dry place, out of reach of children. Best before end date is printed on the base.

How to take it

Take 1 capsule, 1 to 3 times per day, before meals — or as advised. Do not exceed the recommended daily intake.

If you have trouble swallowing capsules, you can pull the capsule apart and stir the contents into a cold drink or cold food. Avoid hot liquids.

Food supplements should not be used as a substitute for a varied diet and healthy lifestyle. Consult your doctor before taking any food supplement or changing your diet.

Your Wellness Journey

From where you are now, to where you want to be — with consistent support.

Where you are now

You already know you want a live culture capsule, and you'd rather buy the higher-count pot than wonder whether the smaller one was enough.

Take it before meals

1 capsule, 1 to 3 times a day, before meals. Water is fine. No refrigeration, no routine to rearrange.

Make it a habit

Live cultures are not a one-off. Most people settle into one capsule a day and simply keep it going.

Stay stocked

30 capsules per pot. Reorder before you run out so there's no gap in the routine.

Before you Buy

The questions we hear most — answered straight.

High Strength Probiotic 20 Billion CFU bottle by The Health Improvers
Does this need to be refrigerated?
No. The strains in this formula are stable at room temperature, so there's no need for fridge space — just keep the pot in a cool, dry cupboard. It also means you can take it away with you without worrying about it.
Why does the label mention bile and acid tolerance?
The eight strains in this formula were selected because they tolerate stomach acid and bile salts. That's a property of the strains themselves rather than a coating on the capsule. We list all eight by name on the pack so you can look up any of them independently.
What's the difference between this and the 4 Billion CFU pot?
The strain list is identical — the same eight organisms in both. The difference is the count: 20 billion viable organisms per capsule here versus 4 billion in the standard pot. This one also has no brown rice flour carrier. We're not going to claim that five times the count does five times anything, because live cultures carry no authorised health claims in Great Britain and nobody can honestly tell you that. Plenty of customers simply prefer to buy the higher count; others are happy with the standard pot at a lower price. Both are made in the same UK facility.
Can I open the capsule if I can't swallow it?
Yes. You can pull the capsule apart and stir the contents into a cold drink or cold food. Avoid hot liquids, and take it fairly soon after opening rather than leaving it standing.
Is this suitable for vegans?
Yes. There are no dairy or animal derivatives in the formula and the capsule shell is hydroxypropyl methylcellulose (HPMC), a plant-based cellulose — not gelatine. It's suitable for vegans and vegetarians.
