Chueotang,
does it really help with Reduced fatigue and improved vitality or recovery?
research showsThe grade is undetermined. Within the sources checked on August 3, 2026, no eligible human study fed chueotang and compared fatigue scales, vitality, or exercise recovery. The direct antifatigue result involved papain-produced loach peptides in mice.
ads claimContaining calcium and protein is not the same claim as restoring vitality. Verdict 1680 is F with 3 points for omega-3 capsules and atrial fibrillation and cannot be transferred to loach soup and fatigue.
Useful facts when choosing a product
- The Korean MFDS K-FIND source URL failed, so the per-100-g protein, sodium, and calcium values could not be confirmed.
- Because the source nutrient values were not confirmed, no 350-g bowl conversion is presented.
- Chueotang combines bone-ground loach with doenjang, perilla seed, and vegetables and is not the same intervention as isolated loach peptide.
- A reliable direct methylmercury value for edible loach or chueotang was not found, so values from other freshwater fish were not substituted.
- Search record: August 3, 2026; PubMed, ClinicalTrials.gov, WHO ICTRP, CRIS, and Korean, Japanese, and Chinese scholarly web searches; exact non-English queries are preserved in the Korean record; zero eligible human chueotang-fatigue studies; animal, peptide, other-species, and other-broth studies excluded.
What the research actually shows
The directly related paper administered papain-produced peptides from loach meat to mice for four weeks and measured forced swimming and blood markers. A 48-person Japanese bonito-broth trial and a Chinese crucian-carp medicinal-soup study used different species, recipes, and populations. KISS blocked access, so its search results could not be checked directly. No eligible chueotang study was found within the checked sources.
Why this is classified as ?
A multilingual repeated search found zero eligible studies feeding chueotang and directly comparing human fatigue, vitality, or recovery, so no score is assigned.
Counterpoint. Animal peptide results can generate a hypothesis but cannot establish efficacy of a bowl of soup in humans.
Rejudgment record. Cross-check applied — English clinical databases and Korean, Japanese, and Chinese searches separated chueotang food, loach peptide, and other fish broths while documenting K-FIND URL failure and blocked KISS access

The scoring table and the verdict agree (?).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Protein, calcium, and sodium content of chueotang | ? | The values could not be confirmed because the K-FIND source URL failed. |
| Chueotang improves human fatigue or vitality | ? | No human study of the claimed endpoint was found. |
