How we rank
We rank by cost-per-dose — price ÷ servings, normalized to the daily dose (500 mg/day) — 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.
When cheapest ≠ best value
The cheapest bottle isn’t automatically the best value: a low per-bottle price usually just means fewer servings or a smaller dose per serving. That is exactly what cost per dose normalises, which is why the ranking above is ordered by it rather than by sticker price. 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 Quercetin forms.
Our data on this: how much the big bottle saves per serving · the gummy tax · the form premium · the price spread.

Quercetin brands we compare — which are third-party tested?
2 of the 34 brands ranked above appear in an independent certifier's own public registry. A certification confirms the label matches the contents — it says nothing about how well the supplement works, and an uncertified brand is not automatically worse.

Retailers and review sites list a price and a serving size but rarely divide it out — this is what a day actually costs, as of October 2026.
What is the typical cost per dose for Quercetin?+
About $0.22 per serving across the 48 quercetin products we can price per dose (combination products are left out — their single label dose belongs to whichever ingredient the product is built around) — the cheapest we track is $0.07 per serving, with most falling between $0.16 and $0.34.

To reach the commonly-studied 500 mg/day dose, DEAL SUPPLEMENT Quercetin 1,000mg Per Serving is the best value at $0.04 per day — cheaper than bottles that look low-priced per serving but are underdosed.
What is the highest-quality Quercetin supplement?+
Of the 34 quercetin brands ranked here, 2 hold a third-party certification we could verify in a public registry: BulkSupplements.com (NSF Certified for Sport), Natural Factors (USP Verified). Certification means an independent lab confirmed the label matches the contents and screened for contaminants — it does not rate how well the supplement works. The cheapest certified option is BulkSupplements.com Quercetin Dihydrate Powder - Quercetin… at $0.23 per serving.
Which Quercetin brands are third-party tested?+
BulkSupplements.com — NSF Certified for Sport; Natural Factors — USP Verified. We only count a brand as tested when it appears in the certifier's own public registry (USP Verified, NSF Certified for Sport, Informed Choice), never on a claim printed on the label. The remaining 32 brands on this page have no certification we could verify.
Which Quercetin is the top rated?+
We don't republish marketplace star ratings — they belong to the retailer, they move constantly, and a 4.6 average tells you nothing about what is in the capsule. The two things you can verify are what a dose costs and whether an independent lab checked the label. On both counts, BulkSupplements.com Quercetin Dihydrate Powder - Quercetin… stands out: NSF Certified for Sport certified at $0.23 per serving.
Independent testing
2 of 34 tracked Quercetin brands here are flagged as carrying independent third-party testing — 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.
