The real cost of Ashwagandha KSM-66, per dose
For the exact same amount of Ashwagandha KSM-66 — the same mg of active ingredient — the priciest products cost a 24× premium over the cheapest. We measured it across 31 tracked products, normalized to cost per mg.
Is the premium brand worth it?
On price, usually not. Two bottles of Ashwagandha KSM-66 can carry the identical active dose at wildly different prices — the spread between the cheap and the premium end is 24× per mg, from a low around $0.0001 to a high near $0.0031. A higher sticker price is not a reliable signal of a better product; most of that gap is branding and margin, not more Ashwagandha KSM-66. 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 Saffron Gummies Supplements with 88.5 mg Saffron Extract at $0.05 per serving — against a catalog median of $0.185/serving.
How we calculated it
Cost per active unit = price ÷ (servings per container × dose per serving), measured in Ashwagandha KSM-66’s dominant dose unit (mg) so we only ever compare like with like — mg of Ashwagandha KSM-66 against mg of Ashwagandha KSM-66.
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 31 active Ashwagandha KSM-66 products from our live Amazon US catalog, recomputed hourly. This is a value comparison, not medical or dosing advice.
