Build a supplement shortlist that fits your budget.
The evidence quiz ranks the whole database. This one narrows to the
146 over-the-counter supplements in it that a reader can actually
price and buy, then fits them to a monthly budget, a diet, and the number of
things you are willing to take in a day. The result is a reading list with costs
attached — not a diagnosis, a prescription, or a shopping instruction.
Every item carries an approximate monthly US retail band and the dose that band is priced at.
Medication, pregnancy, and condition answers add visible interaction context; they never remove rows.
What your budget could not fit is shown too, with its price, so the trade-off is visible.
Educational only. Nothing here is medical advice, and a place on this list is
not a judgment that an item is appropriate, effective, or safe for you. Scores describe
published evidence in studied populations. Cost bands are planning estimates for mainstream
retail products, last reviewed 2026-07-26 — they are not quotes, and this site sells
nothing and earns no commission. Read the full disclaimer →
A first look at what fits. These are ranked research topics with costs attached, not recommendations.
Educational only — not medical advice. A match means database categories or
tags overlap the answers you selected; it does not establish personal benefit, safety, or
appropriateness. Full disclaimer →

Fits your monthly budget
Ordered by how strongly each item matched the goals and context you selected, within the ceiling you set. A high match does not establish a deficiency, diagnosis, or likely personal benefit.
Already in your routine
You told us you already buy these and they also matched your answers, so they are counted against your budget rather than proposed again.
Matched, but did not fit this budget
These matched your answers and were priced out by the monthly ceiling or the daily-item ceiling you selected, cheapest first. Nothing here is ranked lower on evidence for being in this section.
Removed by your ingredient exclusions
Your diet answers removed these. Where a plant-derived or fermentation-derived version is commonly sold, it is noted — the exclusion filters the usual retail form, not the underlying evidence.
