What's Inside BIOME8

Every strain chosen deliberately. Every ingredient there for a reason. Here is exactly what is in BIOME8 and why it works.

Why this formula is built the way it is

BIOME8 is not trying to make one heroic claim from one miracle strain. It is built more like a team: multiple strains working together to support microbial balance, gut barrier function, digestive comfort, and regularity, with a prebiotic to help the bacteria do their job properly.

The specific 8-strain blend is a broad-spectrum adult gut-health formula with evidence pointing to activity across microbe-microbe interaction, gut barrier support, and wider digestive health.

Strain 01
Bifidobacterium lactis
W51
Why it's in here

Core friendly flora foundation strain

Bifidobacteria are among the most recognised beneficial bacteria in probiotic formulas for digestive balance. W51 helps build a more stable gut environment, support bowel regularity, and contribute to day-to-day digestive steadiness.

Strain 02
Bifidobacterium lactis
W52
Why it's in here

Broader Bifido coverage

W52 works alongside W51 to give broader Bifido support across the formula. Using more than one B. lactis strain widens functional coverage rather than relying on a single strain to do all the heavy lifting.

Strain 03
Enterococcus faecium
W54
Why it's in here

Gut ecology and competitive balance

One of the more functional balance strains in the blend, included for its role in helping maintain gut ecology and competing with less desirable microbes. Think of it as one of the balance and competitive pressure strains, helping beneficial flora hold their ground.

Strain 04
Lactobacillus plantarum
W21
Why it's in here

One of the strongest species choices for gut barrier support

L. plantarum is widely linked to gut barrier support, digestive comfort, and microbiota modulation. Research points to its role in supporting tight junctions in the intestinal wall and helping with mucosal defence.

Strain 05
Lactobacillus paracasei
W20
Why it's in here

Broader digestive coverage and barrier support

A broad-spectrum support strain valued for its role in microbial balance, barrier support, and digestive steadiness. It helps make the formula feel more complete rather than narrow in its focus.

Strain 06
Lactobacillus salivarius
W24
Why it's in here

Gut comfort and immune-gut communication

Included for its role in microbial interaction, gut comfort, and the communication between the gut and immune system. Particularly useful in a formula aimed at people whose digestion gets worse when stress levels are high or routines go off track.

Strain 07
Lactococcus lactis
W19
Why it's in here

Formula diversity and ecological balance

Often overlooked in supplement marketing, but L. lactis contributes meaningfully to microbial balance and the production of beneficial compounds in the gut environment. It helps make the formula more complete.

Strain 08
Lactobacillus acidophilus
Classic workhorse strain
Why it's in here

The classic daily probiotic workhorse

L. acidophilus is one of the best-established probiotic species, widely associated with survival through stomach acid and bile, supporting microbiome balance, and bowel comfort. It helps make BIOME8 feel like a proper daily probiotic.

Prebiotic

FOS (Fructooligosaccharides)

The prebiotic part of the formula. FOS acts as a food source for beneficial bacteria, resists digestion in the upper gut, and reaches the colon where it is fermented by beneficial bacteria.

It helps support the bacteria you are taking in the capsule, encourages a more favourable gut environment, and makes the formula synbiotic-style rather than probiotic-only.

How It All Works Together

BIOME8 is built more like a team than a solo act. One strain for balance, one for barrier support, one for colonisation pressure, one for comfort, and a prebiotic to nourish them all.

The result is a well-rounded formula designed for people who want a premium daily gut support product they can actually stick with.

8 strains. Added prebiotics. 20 billion CFU. One capsule.
