Each Ferrocalm capsule contains 1 billion CFU (colony forming units) of our patented friendly bacteria, Streptococcus thermophilus FX856.
FX856 was identified over 10 years’ research and development by experts in gut health at the University of Bristol.
Unlike most probiotics, FX856 can survive and thrive in an environment where iron levels are high, as they are during stress or an active flare-up of a gut condition.
This means that FX856 can help to calm a stressed or troubled gut, right when help is needed the most.

Meet FX856
Our hero strain. Tougher than the rest.
FX856 isn’t your average gut bug. It’s a rare, iron-loving strain with natural anti-inflammatory properties.
Unlike most probiotics that fold under pressure (aka inflammation), FX856 adapts and grows right when you need it most.
- 🧬 Survives the upper digestive tract
- 🔥 Stays active during gut inflammation
- 💊 Supports balance when the microbiome’s out of sync
- 🧪 Clinically tested, university-developed
Why Other Probiotics Fail
If they don’t survive inflammation, what’s the point?
Most probiotics are tested in perfect lab conditions. But your gut isn’t a lab, it’s unpredictable, acidic, and inflamed during IBS flare-ups.
FX856 was selected specifically for its resilience. It can handle stress, stomach acid, and most importantly, inflammation.
It works where most others don’t.
Iron-Compatible
Taking iron supplements? No problem.
Ferrocalm’s strain doesn’t just tolerate iron, it uses it as a growth factor. That’s important if you have anaemia or IBD and need iron therapy (which often makes gut symptoms worse). FX856 works along with iron, not against it.
