The science behind your hormones, mood, skin, and energy — explained without empty promises or generic protocols.
One protocol says cut gluten. Another says fast. None of them explain why your symptoms — mood, skin, energy — all seem connected. Most protocols treat isolated symptoms because they ignore the mechanism linking them.
Gut Decoded is not a 7-day plan. It's a peer-reviewed-research-based explanation of how your gut communicates with your brain, skin, immune system and metabolism — so you understand the why before you attempt the what.
Serotonin, the vagus nerve and the biology of brain fog. Around 90% of the body's serotonin is made in the gut, not the brain.
Why your digestion shows up on your face: the inflammation that links the gut to acne, rosacea and eczema, which topical routines never reach.
Why diversity matters more than any single strain, and why it outlasts whatever probiotic is trending this year.
70–80% of your immune cells sit in the gut wall. What that means for inflammation, and for how your defences behave everywhere else.
The same meal can give two people two different blood-sugar curves. The bacteria behind energy and metabolism, and the estrobolome's role in hormonal balance.
Each point in the guide is tied to a named, peer-reviewed study, with a full bibliography of more than 100 studies at the end. You're reading what the research shows, not someone's opinion, and you can check any of it yourself.
You won't find a 7-day plan or a list of miracle supplements. You'll find the framework to understand your own body and evaluate any protocol on your own terms.
I'm an independent researcher and writer, and I built Gut Decoded out of frustration with a wellness space that answers every question with a protocol and never explains the mechanism underneath it.
My approach is simple: read the peer-reviewed literature, report what it actually shows — clearly, and without the hype — and let you decide what it means for you. I'm not a doctor, and this isn't medical advice; it exists to make accurate, commercially unbiased gut-health science readable for anyone.
Bloating, Decoded: why your stomach can swell without extra gas, what the guidelines say about probiotics, and when to see a GP. No email needed.
