Third-Party Testing & Purity
30% of scoreThird-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. Purity is backed by that testing, though the brand publishes less assay detail than the premium picks.

Marketing Claims Vs. Reality
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.
250mg TUDCA supports liver health.
250mg is a valid dose within the 250-500mg cholestasis range and TUDCA has a strong mechanistic rationale (PMID 24891994), 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.
What Our Test Actually Found
Best value without a quality compromise
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.
Ideal for a first, honest trial
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.
Full analysis: all pros & cons (6), buy if / skip if
- Best price among credible, third-party-tested mainstream options
- ISO-accredited lab testing and GMP/FDA-registered manufacture
- Single-ingredient, synthesized (non-bear-bile) TUDCA
- Cheap enough to run a 500mg/day serving without pain
- Publishes less assay detail (no HPLC-vs-USP statement) than the top two
- Only 250mg/cap, so 500mg/day is a two-cap serving
- Best price among credible, third-party-tested mainstream options
- ISO-accredited lab testing and GMP/FDA-registered manufacture

Nutricost gives you third-party-tested 250mg TUDCA at the best mainstream price (~$0.42/cap). It lacks the published HPLC-vs-USP detail of Double Wood or the dual testing of BodyBio, but for a first 250mg/day trial the value-to-quality ratio is the best here. Buy it if you want to test TUDCA without a premium; step up only if you specifically want deeper verification.
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.
The sensible default
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.
If This Doesn’t Fit — Try These
01Double Wood
Double Wood wins because it removes the one thing you cannot verify yourself: whether the powder is real, potent TUDCA.
07BulkSupplements 250 mg
BulkSupplements is the reliable workhorse: correct basics, real batch testing, and a powder route for the dose-tinkerers.
Quick Answers
Is the cheap price a red flag?
No. Nutricost keeps ISO-accredited third-party testing and GMP manufacture despite the low price. The genuinely risky cheap options are the ones with minimal published testing — not this one.
Should I start at 250mg or 500mg?
Many people start at 250mg/day (one capsule) and can move to 500mg (two capsules) if tolerated. There's no established OTC target; the 250-500mg range is extrapolated from cholestasis studies.
