“Nutricost TUDCA is third-party tested at an ISO-accredited laboratory.”
Product certifications state third-party testing at an ISO-accredited lab and manufacture in a GMP/FDA-registered facility.
Nutricost is the value-leader that doesn't cut the corners that matter. At around $0.42 a capsule it's the cheapest genuinely mainstream TUDCA here, yet it's still third-party tested at an ISO-accredited lab and made in a GMP/FDA-registered facility. It's single-ingredient, synthesized (not bear-bile) TUDCA at the standard 250mg. The honest limitation is the same one that dogs every product on this list — there's no clinical outcome data behind the OTC supplement itself — but if you want to run a low-cost, low-risk trial without overpaying, this is the smart starting point.

Read the complete TUDCA guide →Standard synthesized 250mg TUDCA, non-GMO and gluten-free. Purity is backed by ISO-accredited third-party testing, though the brand publishes less assay detail than the premium picks.
Third-party tested at an ISO-accredited lab in a GMP/FDA-registered facility — solid and credible, just not the layered or HPLC-vs-USP-documented programs of the top two.
250mg/cap is the low end of the 250-500mg range. Fine for a standard daily dose; reaching 500mg needs two caps but stays cheap at this price.
Well tolerated single-ingredient formula; usual mild GI/bile-shift effects only. No stacked ingredients to complicate tolerability.
~$0.42/cap is the best price among credible, tested mainstream options — the clearest value case in the roundup for a first trial.

“250mg TUDCA supports liver health.”
250mg is a valid dose within the 250-500mg cholestasis range and TUDCA has a strong mechanistic rationale (PMID 24891990), but no OTC human outcome trial validates liver-health benefit for the supplement.
“This TUDCA is not derived from bear bile.”
Sourcing notes confirm the TUDCA is synthesized rather than animal-bile-derived, consistent with standard modern manufacture.
Nutricost is cheaper than most peers yet keeps ISO-accredited third-party testing and GMP manufacture — it doesn't drop the verification that separates real TUDCA from the bargain-basement risk (see Best Naturals). That combination is why it's the value winner rather than the cheapest per cap.
Because OTC TUDCA benefit is unproven, spending the least to test your own response is rational. At ~$0.84 for a 500mg/day serving, Nutricost lets you run a fair trial before committing to a premium brand.
Nutricost is what most people should buy first: credible third-party testing, standard 250mg dose, and the best mainstream price. It cedes the top two spots on verification depth, not on quality. Given that OTC TUDCA's benefits are unproven, testing your own response at the lowest sensible cost is the smart move — and this is the product to do it with.

Meta-analysis found UDCA improves liver biochemistry but did not significantly reduce mortality or transplant — a caution that biochemical change need not equal hard outcomes.
