How we rank
We rank by cost-per-dose — price ÷ servings, normalized to the daily dose— so bottle sizes and strengths compare fairly. Prices are scraped at publication and re-checked when the catalog refreshes (see the “Prices checked” stamp above). There is no paid placement and no kickback for ordering. Full methodology · Editorial standards.
That cost-per-dose number is the one most retailers and review sites leave out — they’ll show a sticker price and a serving size, but not what a day actually costs. We compute it for every product so you can compare like for like.
When cheapest ≠ best value
The cheapest bottle isn’t automatically the best value: a low-absorption form (magnesium oxide is the classic example) can look cheap per milligram yet deliver less of what you actually absorb. Where forms differ, compare cost per absorbed or elemental unit, not the compound weight on the label. A bigger bottle isn’t automatically cheaper per dose either — this list already ranks by cost per dose, so a larger count only wins if it truly costs less per serving. Compare D-Mannose forms.
Our data on this: the big bottle saves a median ~86% per serving · the gummy tax (~2× more) · the form premium · the price spread.
Full ranking by cost per dose
Cost-per-serving normalizes price across bottle sizes — a 60-count and a 365-count compare fairly.

Independent testing
Independent third-party testing is a voluntary check of a product's identity, potency and contaminants by an outside lab. It's a quality signal, not a value or efficacy claim. Confirm any brand's current status on the official registries:
Testing status is self-reported by the brand or drawn from public certification and may change — always verify on the official registry before purchase.
