The real cost of TUDCA, per dose
For the exact same amount of TUDCA — the same mg of active ingredient — the priciest products cost a 13× premium over the cheapest. We measured it across 23 tracked products, normalized to cost per mg.
Is the premium brand worth it?
On price, usually not. Two bottles of TUDCA can carry the identical active dose at wildly different prices — the spread between the cheap and the premium end is 13× per mg, from a low around $0.0003 to a high near $0.0034. A higher sticker price is not a reliable signal of a better product; most of that gap is branding and margin, not more TUDCA. 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 Totaria TUDCA Supplement 1200mg (Tauroursodeoxycholic Acid) at $0.18 per serving — against a catalog median of $0.466/serving.
How we calculated it
Cost per active unit = price ÷ (servings per container × dose per serving), measured in TUDCA’s dominant dose unit (mg) so we only ever compare like with like — mg of TUDCA against mg of TUDCA.
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 23 active TUDCA products from our live Amazon US catalog, recomputed hourly. This is a value comparison, not medical or dosing advice.
