The science
Your Formula is engineered, not guessed.
An algorithm turns your data into a recipe, drawing on a 70+ ingredient library weighed for evidence and screened against your medications before anything is made. The method is granted two US patents. Read as deep as you want to.
The trust problem
Everyone says clinical.
Almost no one shows you why.
The supplement aisle runs on confident words: clinical, advanced, proven. The hard part was never saying them. It’s showing the work behind them. So rather than ask you to trust us, this page shows you the engine, stage by stage.
“Every brand says clinical. I can’t tell who’s actually telling the truth.”
Fair. A word on a label isn’t evidence. What follows is a method you can check, not another adjective.
“A quiz matched me once and called it personalized.”
Matching you to something already on a shelf isn’t the same as building a Formula from your data, then rebuilding it monthly. Here’s that difference, shown.
The engine
How your data
becomes your Formula.
Your Formula is built, not picked. It starts with real inputs from you. Then the algorithm does four things with them, in the same order, every time.
What you tell us
Your medications, how you feel, your goals. The quiz captures the full picture, in your words.
Your wearable
Connect it once. Your sleep, recovery and activity sync in as real inputs.
Your blood markers
Upload your latest results. Your Formula reflects your actual biology, not a guess.
One evidence-led path, every month. Every choice the algorithm makes traces back to the strength of the evidence behind each ingredient. That is what the library holds, and how it is graded.
We use your inputs to personalize nutrition, not to diagnose. See the four-step monthly loop
The evidence library
A working library,
not a number on a banner.
70+ ingredients, each in a named active form with a disclosed dose. Personally draws on PubMed, the U.S. National Library of Medicine’s database of peer-reviewed medical research, as a working library. Explore what it covers, and the named forms behind each area.
There's no average body.
Your body leans on different nutritional foundations at different times: sleep, energy, focus, mood, stress, immunity and recovery. Across all of them, your Formula is drawn from a library of 70+ evidence-assessed ingredients, matched to you and re-tuned as you change. There’s no average body, so we don’t make an average jar.
These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. Your personalized Formula draws a subset of the 70+ ingredient library matched to you.
How an ingredient earns its place
Strong evidence counts.
Weak evidence isn’t dressed up.
Every ingredient the library might use is read against the published research, not an in-house opinion. Here is how a study earns its weight, and how we keep the library current.
Read against the research
Every candidate ingredient is assessed against the published research, not an in-house opinion or a marketing claim.
Weighed for quality
Each study is graded against a defined standard, so strong evidence counts and weak or preliminary evidence is discounted, not dressed up.
Kept current
The library is reassessed every month and updated as new research lands, so your Formula reflects the current weight of evidence.
How the weight is assigned, honestly:
This is the question Dr Jatin Joshi, a Researcher at the University of Oxford’s Centre for Evidence-Based Medicine, studies: what to do when the evidence points in more than one direction. The same method sits under every Formula.
Safety by design
Most supplement brands don’t ask.
We do.
When you tell us your medications and conditions, the algorithm screens against them before your Formula is built, not after. Anything with a known interaction for your profile is left out at the point of formulation. Sometimes the safest Formula is a smaller one. If something you tell us looks unsafe to formulate around, we won’t proceed, and we’ll say why. Personally is a nutrition layer, not medical care, and not a substitute for talking to your doctor.
- The medications you declare
- The conditions you tell us
- Known interactions for your profile
The artifact
The method is patented.
Here’s what that protects.
Two granted US patents cover the system end to end: how your data becomes a recipe, and how that recipe becomes a product made for one person. We don’t lead with them. A patent is simply proof the method on this page is real engineering, not a word on a label.
The personalization method, end to end: data in, recipe out.
Its manufacture: every Formula weighed out for one person at a time.
- Each ingredient set to its own dose
- Your Formula reassessed every month
- Every Formula made for one person, not a batch
Why you can trust this
Built by a surgeon.
Backed by evidence.
Made under cGMP.
No famous face is telling you to trust us. The proof is who built Personally, how it’s made, and a method that shows its work, so you don’t have to take our word for it. Each of these goes a level deeper.
A surgeon's standard
Founded by Dr Jatin Joshi, surgeon and Hon Professor of Surgery (Translational Research), UCL, who built the system he wished existed.
Evidence-graded method
We use evidence-analysis tools developed by the Centre for Evidence-Based Medicine at the University of Oxford, among others. The same method sits under every Formula.
Boulder cGMP manufacturing
Made in the United States under FDA cGMP conditions. No proprietary blends.
An evidence-assessed library
Formulas draw on 70+ evidence-assessed ingredients, in named active forms with disclosed doses.
“RDAs began as 1940s population nutrition standards. Useful for public health. Not designed for your medications, symptoms, goals or monthly changes.”

FAQ
What if my formula isn't right for me?
You review every formula in the 7 days before it ships, and it's rebuilt every month around what's changed. So nothing is set in stone, and nothing ships that you haven't seen.
Is more always better?
No. The aim is the right dose for you, not the highest one. More of an ingredient isn't more benefit, and some have a point past which it stops helping.
Will I actually feel anything?
Some people notice changes in areas such as energy, sleep or wellbeing within the first month, especially where the formula addresses a clear nutritional gap or transition. Others may not feel an obvious change. What we promise is an evidence-informed formulation method that adjusts as your dynamic biomarkers do.
How the screening works →Who built Personally?
Dr Jatin Joshi, a surgeon and Hon Professor of Surgery (Translational Research), UCL, after seeing the same gap his patients kept falling into. The method is protected by two US patents.
The founder's story →What actually arrives, and when?
Your Welcome Kit: a morning powder you mix into a drink, an evening shot, a shaker and a scoop. You just drink it, morning and evening. It arrives in about 5 to 7 days, then a rebuilt formula follows each month.
How long until I see my formula?
A preview in about two minutes. Your full formula in about fifteen.
