Already had blood, stool or microbiome tests? Upload them — our peer-reviewed evidence engine tells you what they mean, what may help, and what to test next, then re-test to see what moved. Not tested yet? Explore your condition first — free, no sign-up.
Different symptoms, same inflammatory machinery. Psoriasis, eczema, rheumatoid arthritis, IBD, depression, heart disease — the markers that flag one keep showing up in the others. Move the markers, and you may move more than one thing at once.
Pick your condition — not a biomarker you've never heard of. We show the markers that sit behind it and why they matter, in plain language.
Scored by how robustly the research backs it for your condition. How strongly studies show it moves the markers that matter most — not by what's trending.
Re-run the same test after 12 weeks and see exactly what changed. Most labs hand you numbers and walk away. Measure, act, measure again.
All free. Bring a test you've already had done — or explore first.
Any blood, stool or microbiome test you've had done. Snap a photo, upload the PDF, or paste the numbers.
any lab · you keep itPlain-English meaning for every marker, and the evidence for what may help. What it points to, with the studies. Information, not advice.
free · peer-reviewedPick something to add or ease off. Log what you actually do over 8 weeks — honestly. That's what makes your before/after mean something.

before → afterSee the markers behind it, what the evidence says may help, and which tests are worth getting — then upload your own results to make it yours.
No. Everything here — the explorer and your uploaded-results report — is educational: it shows what published, peer-reviewed research says, matched to the markers you enter. It is information, not medical advice, and not a diagnosis. We don't sell supplements. Always talk to a qualified healthcare professional before changing anything, and keep your GP in the loop for anything serious.
Yes, free — and there's no catch. We don't sell supplements and make nothing from what you choose to take. The deal is simple: in return, your anonymised before/after helps build the evidence base, so everyone learns what actually works. That's the whole model — think of it as a giant, distributed study you can opt into.
No — you bring a test you've already had done, from any lab (blood, stool, or a microbiome test). We just read it against the evidence. Haven't tested? The explorer shows which markers are worth measuring for your condition, so you can get them done anywhere.
Markers move over roughly 8–12 weeks, so that's when you re-test. Your evidence report is instant; the "proof" comes when you upload your follow-up and see the before/after.
Causal was designed by someone who reduced their own psoriasis to almost zero through careful iteration across diet, lifestyle and natural supplementation — without a hardcore elimination diet. That story is the foundation, not a promise. Read why Causal exists →
