Supplement quiz, FAQ

Is the supplement quiz free?
Yes. Both the 2-minute Express and the 5-minute Complete quiz are free with no signup. You answer a few questions about your goals, sleep, energy, and stress, and get a personalised 4 to 7 supplement stack instantly, each pick with its dose, timing, and the evidence behind it.
How does the quiz decide what supplements I need?
It matches your goals and answers against an evidence-graded database of 200+ ingredients, then ranks the best fits and checks them for interactions and redundancies, so the stack you get is coherent rather than a random list.
Which quiz should I take, Express or Complete?
Take Express. It gives about 90% of the accuracy in 30% of the time. Choose Complete if you want to factor in current supplements, medications, health conditions, or upload bloodwork for a deeper match.
Do you sell the supplements?
No. suppdoc does not sell its own supplements. We recommend evidence-led options and link to trusted retailers, so the advice is not biased toward a house brand.
