False
“Each serving provides 1000mg of TUDCA.”
The 1000mg is a proprietary blend of eight ingredients (TUDCA, milk thistle, dandelion, beet root, probiotics and more), so the actual TUDCA content is undisclosed and well below 1000mg.

8-in-1 TUDCA 1000mg with Milk Thistle, 120 Capsules Review
5.5/10SAC Product Score™
On paper the 8-in-1 blend looks generous: TUDCA plus milk thistle, dandelion, beet root, probiotics and more, at a '1000mg' headline. In practice that 1000mg is a proprietary blend, which means the label does not disclose how much is actually TUDCA versus filler botanicals — and in a category where purity and verified dose are the entire axis, that's disqualifying. The milk-thistle pairing mirrors a popular stack, and the price and count are fine, but you cannot confirm you're getting a research-range TUDCA dose. When the one number that matters is hidden, the rest doesn't save it.

Form, Bioavailability & Purity25%5.5/10
Eight ingredients under a 1000mg proprietary blend. You cannot verify the TUDCA quantity or purity — the blend structure defeats the one thing that matters for a bile-acid supplement.
Third-Party Testing30%5.2/10
Non-GMO and GMP, but a multi-ingredient proprietary blend is inherently hard to verify per-component, and no HPLC-vs-USP TUDCA assay is published.
Dose vs Clinical Range20%4.5/10
Headline 1000mg is the total blend, not TUDCA. The undisclosed TUDCA fraction is very likely below the 250-500mg range — the weakest, least-confirmable dose delivery here.
Tolerability & Safety10%6/10
The added botanicals and probiotics are generally benign, but more ingredients means more interaction and tolerability variables, and no way to know which is doing what.
Value15%7/10
120-count at a modest price looks cheap per cap, but if the TUDCA dose is sub-therapeutic the value is illusory — you may be paying mostly for filler botanicals.

Marketing claims vs. reality
Partial
“The milk-thistle stack enhances liver support.”
TUDCA + milk thistle is a common pairing with plausible complementary rationale, but the proprietary blend hides both doses, so no meaningful efficacy can be inferred.
Not verified
“This is a cost-effective way to get TUDCA plus a stack.”
Low per-cap price cannot be judged cost-effective when the TUDCA dose is undisclosed and likely sub-therapeutic — you can't price what you can't see.
What our test actually found
01The blend hides the one number that matters
This category's whole axis is verified TUDCA dose and purity. A proprietary blend that lumps TUDCA with seven other ingredients under a single 1000mg figure makes that verification impossible — the format is fundamentally mismatched to the product's purpose.
02Build your own stack instead
If you want the TUDCA + milk thistle combo, buy a single-ingredient TUDCA at a known 250-500mg dose (e.g., Double Wood or Nutricost) and add a standardized milk-thistle product. You get the same stack with dosing you can actually confirm.
Pros & cons, no sugar-coating
Pros
- Convenient all-in-one liver-support blend concept
- Includes the popular milk-thistle pairing plus supporting botanicals
- Large 120-count, 2-month supply
Cons
- Proprietary blend hides the actual TUDCA dose — disqualifying for this category
- Headline '1000mg' is total blend, not TUDCA
- No published TUDCA-specific purity/potency assay
- Likely sub-therapeutic TUDCA behind filler botanicals
Skip — the format defeats the purpose
The 8-in-1 blend fails on the exact axis TUDCA buyers care about: you cannot tell how much actual TUDCA you're getting. The '1000mg' is a proprietary blend, the botanical extras pad the number, and no TUDCA-specific assay is published. Convenient concept, wrong execution. Buy a single-ingredient TUDCA at a verified dose and stack milk thistle yourself if you want it.
