Garlic-powder tablets 800 mg/day,
does it really help with Improvement of ultrasound steatosis grade in adults with NAFLD?
research showsGrade C with 54 points. In a trial with 110 randomized and 98 completing, ultrasound steatosis grade improved in 24/47 versus 8/51. The paper's value labeled a ‘relative risk’ of 5.6 corresponds to odds based on the event counts; the ITT risk ratio was 3.0 (95% CI 1.5-6.1; P=.001). Ultrasound grade is not MRI-PDFF or histology, and this is one short trial.

Useful facts when choosing a product
- This verdict applies only to the displayed formulation, route, dose, duration, population, endpoint, and comparator.
- Raw garlic, powder, garlic oil, stabilized-allicin products, aged garlic extract, black garlic, fermented garlic, and isolated S-allylcysteine are not interchangeable.
- Caution. Review gastrointestinal and bleeding risks, and do not replace liver-disease or lifestyle treatment.
Chamgap Semantic Classification Code
Permanent code issued
S.garlic-powder.oral.ultrasound-steatosis-grade.improve.placeboSupplements and nutraceuticals > Garlic powder > Oral > Ultrasound steatosis grade > Improvement claim > Placebo
Bound to ultrasound grade after 800 mg/day for 15 weeks; MRI-PDFF, histology, and liver enzymes are separate. The code identifies the intervention and claim; it never contains the evidence grade, score, or safety result.
Exact Claim Classification
These independent facets prevent evidence from different forms, routes, populations, effects, and comparators from being mixed.
| Intervention class | S · Supplement or nutraceutical |
|---|---|
| Canonical ingredient or intervention | Garlic powder |
| Source or part used | Powdered Allium sativum L. cloves |
| Formulation or processing | Two 400-mg garlic-powder tablets; alliin specification unverified |
| Route | Oral |
| Dose | 800 mg/day |
| Duration | 15 weeks |
| Population | Adults with ultrasound-diagnosed NAFLD |
| Effect or condition | Improved imaging steatosis grade |
| Primary endpoint | Proportion with at least one-grade ultrasound steatosis improvement at week 15 |
| Comparator | Matching placebo |
| Duplicate-detection key | Garlic powder|Two 400-mg garlic-powder tablets; alliin specification unverified|Oral|Adults with ultrasound-diagnosed NAFLD|Improved imaging steatosis grade|15 weeks |
What the research actually shows
The 110 randomized, 98 completers, completer events, ITT risk ratio, and the paper's mislabeled effect measure were separated; fermented and black-garlic liver-enzyme verdicts were excluded.
Why this is classified as C (54)
I2 and E+ are two strengths, but S, R1, and the under-200 B1 cap yield C/54.
Counterpoint. A separate 1,600-mg 12-week trial also reported an imaging signal, but the dose and protocol differed and were not counted as product-matched confirmation.
Rejudgment record. Independent Codex cross-check — One formulation, route, population, claim, principal endpoint, and comparator
| Endpoint | S | Surrogate marker - laboratory or imaging measures |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
| Precision | CX | No pooled confidence interval could be confirmed |
The scoring table and the verdict agree (C).

Chamgap is an information source. It reports what research has and has not confirmed; it does not tell readers what to take or buy.
