Why It Scores 7.0 — And The Label Line Behind Each Number
Third-Party Testing & Purity
30% of scoreManufacturer per-batch testing for purity and identity in a cGMP-registered facility. Credible, but less independently documented than the published HPLC-vs-USP or dual-lab programs above it.
- Testing
- Manufacturer per-batch purity/identity; cGMP facility
Form & Bioavailability
20% of scoreStandard synthesized 250mg TUDCA; the optional bulk powder adds dose-control flexibility not offered by capsule-only rivals.
- Form
- Capsule (also sold as bulk powder)
Dose vs Functional Range
20% of score250mg/cap at the low end of the range; the powder option lets precise users weigh out anything up to 500mg, a genuine flexibility edge.
- Dose
- 250mg per capsule
Tolerability & Safety
15% of scoreSingle-ingredient and well tolerated; only the usual mild bile-related GI effects. No stacked components to complicate things.
Value
15% of score~$0.47/cap is mid-pack — priced near Double Wood without matching its published verification, and above Nutricost. The powder can improve cost-per-gram for heavy users.

Marketing Claims Vs. Reality
Each batch is tested for purity and identity.
Listing confirms manufacturer per-batch testing for purity and identity in a cGMP-registered facility.
The bulk powder format gives better dose control than capsules.
BulkSupplements sells TUDCA as loose powder, which by definition allows weighed dosing between 250-500mg rather than fixed capsule increments.
250mg daily meaningfully supports liver function.
250mg is a legitimate dose in the 250-500mg range with mechanistic support (PMID 16741551), but no OTC outcome trial confirms liver-function benefit for the supplement.
What Our Test Actually Found
The powder option is the real differentiator
Most TUDCA rivals lock you to fixed capsule doses. BulkSupplements also offering loose powder means dose-precise users can weigh exact amounts and often lower cost-per-gram — a practical edge for people running the top of the range.
Testing is fine, not leading
Per-batch purity/identity testing is credible, but it's manufacturer-run and less publicly documented than Double Wood's HPLC-vs-USP or BodyBio's dual program. At a similar price, that gap is why it ranks mid-pack.

BulkSupplements delivers a clean, per-batch-tested 250mg TUDCA with a powder option for people who want to dial dose. It's reliable but doesn't distinguish itself: the testing isn't as deeply documented as the top picks, and the price sits close to better-verified options. Consider it if you like the brand's bulk ecosystem; otherwise Nutricost is cheaper and Double Wood is better verified.
BulkSupplements is the utilitarian pick: a single 250mg TUDCA capsule per serving, manufacturer-tested for purity and identity per batch, made in a cGMP-registered facility. No stack, no gimmicks. Its quiet advantage is that the brand also sells TUDCA as bulk powder, so if you want precise dose control you can migrate to that. The knock is that the testing is manufacturer/per-batch rather than the published HPLC-vs-USP or dual-lab programs of the top picks, and at ~$0.47/cap it's priced near Double Wood without matching that verification. Solid, not standout.
A dependable middle-of-the-pack workhorse
BulkSupplements does the job: pure, per-batch-tested 250mg TUDCA with a handy powder option for dose tinkerers. It just doesn't lead on any single axis — the verification isn't as documented as the top two, and the price doesn't undercut Nutricost. Buy it if you value the bulk ecosystem or want powder dose control; otherwise the picks above offer more for the money.
If This Doesn’t Fit — Try These
03Nutricost 250 mg
Nutricost is the safe, sane default for a first TUDCA bottle — trusted brand, real third-party testing, honest single-ingredient label, and a price that does not sting.
01Double Wood
Double Wood wins because it removes the one thing you cannot verify yourself: whether the powder is real, potent TUDCA.
Quick Answers
Should I buy capsules or the powder?
Capsules are simpler for a fixed 250mg dose. Choose the powder only if you want to weigh precise amounts (e.g., an exact 500mg) or lower cost-per-gram — and use a milligram scale, since bile acids are potent and bitter.
Is manufacturer testing as good as third-party?
It's credible for purity and identity, but independent third-party programs (like Double Wood's HPLC-vs-USP or BodyBio's external cGMP testing) carry more weight. For most users the per-batch testing here is sufficient.
