About 3 minutes. We ask 10 short questions about your goals, lifestyle, body, and budget. You can save progress and come back later, answers are stored in your browser.
No. Your answers stay on your device. We don't collect emails unless you opt in to save your results.
Pick the closest match. The recommendation engine works on a profile across all answers, no single question dominates the output.
Each supplement in our database is tagged with the goals and conditions it addresses. We build a profile from your quiz, score every supplement by how well it matches, apply safety filters (pregnancy, blood thinners, allergies), then pick the highest-scoring options within your budget.
No. suppdoc.io offers educational guidance based on your inputs and the published evidence. For diagnosis or treatment, please consult a qualified clinician.
Yes, we curate well-established brands (NOW Foods, Doctor's Best, Sports Research, Thorne, Jarrow, Garden of Life, etc.). All are widely trusted, third-party tested, and have decades of track record.
We link to trusted global retailers like iHerb and Amazon, where you can compare brands, prices, and shipping. You buy direct from the retailer, we don't sell or ship anything ourselves.
Not at all. You're free to buy your stack anywhere. The product information (brand, dose, form) is the same regardless of where you shop.
If you click through to a retailer from our site and buy something, the retailer pays us a small commission, at no extra cost to you. It's how we fund building suppdoc.io without selling our own products.
Our engine automatically removes supplements that aren't recommended during pregnancy (e.g. ashwagandha). However, you should ALWAYS consult your obstetrician before starting any new supplement during pregnancy or lactation.
Talk to your doctor or pharmacist before starting any new supplement. Several common supplements interact with medications, particularly blood thinners, thyroid medication, and antidepressants.
We ask about common allergies in the quiz and filter the stack accordingly. Always double-check product labels for trace ingredients before purchasing.
