Supplement Stack Builder
You rarely take just one supplement, but every bottle is priced and dosed as if you do. Build your actual stack here: see what it really costs per day at clinically effective doses, and catch the quiet overlaps, the same ingredient arriving from two different bottles, before you double a dose without meaning to.
Stack questions, answered straight
How is the cost per day calculated?
Each pick's figure is its cost per clinically effective dose, the same number shown on its scorecard: the product's price divided across the doses used in the research, not the doses on the marketing label. The stack total is simply those figures added up. It is often different from cost per pill, because underdosed products need more pills to reach an effective dose.
What do the overlap warnings mean?
They fire when two or more of your picks supply the same ingredient, for example two different magnesium forms, or a multivitamin alongside a standalone mineral it already includes by definition. The warning is label arithmetic, not a medical judgment: doses add up across products, so check each label against the daily total you actually intend.
Does this tool check interactions with medications or between supplements?
No. It checks ingredient overlap only. It does not know your health situation, your medications, or how supplements interact with each other or with prescriptions. Bring your stack to a doctor or pharmacist before starting it, especially if you take any medication or are pregnant or nursing.
How do I save or share my stack?
The stack lives in the page URL as you build it, so the address bar is the save file. Use the copy button for a shareable link. Nothing is stored on our servers and no account is needed.
Where do the product picks come from?
The same place as everything on this site: each supplement type's scorecard. Top Pick is the highest execution score currently buyable; Best Value is the lowest cost per effective dose among products scoring at least 60 that qualify for the value slot. Every row links its full scorecard so you can see the scoring trail.
