BulkSupplements.com TUDCA 250mg, 60 Capsules Review
6.9/10SAC Product Score™
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.

Form, Bioavailability & Purity25%6.8/10
Standard synthesized 250mg TUDCA, per-batch tested for purity and identity. Purity is adequately controlled; the optional bulk powder adds dose-control flexibility not offered by capsule-only rivals.
Third-Party Testing30%7/10
Manufacturer 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.
Dose vs Clinical Range20%7/10
250mg/cap at the low end of the range; the powder option lets precise users weigh out anything up to 500mg, a genuine flexibility edge.
Tolerability & Safety10%7.5/10
Single-ingredient and well tolerated; only the usual mild bile-related GI effects. No stacked components to complicate things.
Value15%6.5/10
~$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
Verified
“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.
Partial
“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
01The 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.
02Testing 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.
Pros & cons, no sugar-coating
Pros
- Per-batch purity and identity testing in a cGMP facility
- Bulk powder option enables precise dose control
- Clean single-ingredient formula, no filler stack
- Reliable, widely available brand
Cons
- Testing less independently documented than top picks
- Priced near better-verified Double Wood without matching it
- Only 250mg/cap; two caps needed for 500mg/day
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.
