The real cost of Quercetin, per dose
For the exact same amount of Quercetin — the same mg of active ingredient — the priciest products cost a 6.5× premium over the cheapest. We measured it across 45 tracked products, normalized to cost per mg.
Is the premium brand worth it?
On price, usually not. Two bottles of Quercetin can carry the identical active dose at wildly different prices — the spread between the cheap and the premium end is 6.5× per mg, from a low around $0.0002 to a high near $0.0011. A higher sticker price is not a reliable signal of a better product; most of that gap is branding and margin, not more Quercetin. Pay up only for a verifiable difference — third-party testing, or a specific better-absorbed form — never for the packaging.
Right now the best value in our catalog is DEAL SUPPLEMENT Quercetin 1,000mg Per Serving at $0.07 per serving — against a catalog median of $0.218/serving.
How we calculated it
Cost per active unit = price ÷ (servings per container × dose per serving), measured in Quercetin’s dominant dose unit (mg) so we only ever compare like with like — mg of Quercetin against mg of Quercetin.
Spread = the 90th-percentile cost per mg ÷ the 10th-percentile. Using the 10th/90th percentiles (not the absolute min/max) deliberately excludes one-off outliers and mislabeled listings. Based on 45 active Quercetin products from our live Amazon US catalog, recomputed hourly. This is a value comparison, not medical or dosing advice.
