Design outcomes

Primary

MeasureTime frameDescription
Changes in alanine aminotransferase (ALT) levels3 monthsALT level decline indicates improved liver function, assessed via blood tests.
Changes in aspartate aminotransferase (AST) levels3 monthsAST level decline indicates improved liver function, assessed via blood tests.

Secondary

MeasureTime frameDescription
Changes in malondialdehyde (MDA) levels3 monthsEvaluate the effects of test products on oxidative stress levels. MDA: The unit is μmol/L.
Changes in the level of superoxide dismutase (SOD)3 monthsEvaluate the effects of test products on oxidative stress levels. SOD: The unit is U/mL.
Changes in basal metabolic rate3 monthsThe Mifflin-St Jeor equation was used to evaluate the subject's basal metabolic level, reflecting the body's energy expenditure at rest.
Metabolic index3 monthsBlood pressure: Evaluate the effects of the tested product on age-related cardiovascular health and monitor changes in systolic and diastolic blood pressure.
Gamma-glutamyltransferase (GGT)3 monthsEvaluate the effects of the tested product on liver-related components. GGT: The unit is U/L.
Total bilirubin (TBil)3 monthsEvaluate the effects of the tested product on liver-related components. TBil: Unit: μmol/L.
Uric acid3 monthsEvaluate the effects of the tested product on liver-related components. Uric acid: unit: μmol/L.
Weight3 monthsEvaluate the effects of the tested product on body weight. Weight: Unit: kg.
BMI (body mass index)3 monthsThe effects of the product on body mass index were evaluated. BMI: Unit: kg/m².
Low-density lipoprotein (LDL)3 monthsThe effect of the tested product on lipid levels was evaluated. LDL: The unit is mmol/L.
Total cholesterol3 monthsThe effect of the tested product on lipid levels was evaluated. Total cholesterol: Unit: mmol/L.
Triglyceride3 monthsThe effect of the tested product on lipid levels was evaluated. Triglyceride: The unit is mmol/L.
Changes in glutathione (GSH) levels3 monthsEvaluate the effects of test products on oxidative stress levels. GSH: Unit: μmol/L
Fatigue Severity Scale (FSS)3 monthsEvaluate the fatigue severity of the tested product. FSS score: The unit is points, ranging from 1 to 7 points. 1 score: No fatigue Score 7: Extreme fatigue Higher score: indicates more severe fatigue
Pittsburgh Sleep Quality Index (PSQI)3 monthsParticipants' overall sleep quality over the past three months was assessed. PSQI score: The unit is points, ranging from 0 to 21 points. 0 score: Best sleep quality 21 points: worst sleep quality Higher score: indicates poorer sleep quality
Short-chain fatty acids (SCFAs)3 monthshort-chain fatty acids: Short-chain fatty acids such as acetic acid, propionic acid, and butyric acid are analyzed in stool samples by gas chromatography-mass spectrometry (GC-MS) or high performance liquid chromatography (HPLC). Acetic acid: unit: μmol/g fecal matter. Propionic acid: The unit is μmol/g feces. Butyric acid: The unit is μmol/g feces.
Fecal flora structure (16S rRNA sequencing)3 months16S rRNA sequencing: Bacterial 16S rRNA genes in fecal samples are analyzed by high-throughput sequencing techniques to determine the diversity and composition of the gut microbiota. Diversity index: such as Shannon index, Chao1 index, etc., used to measure the diversity of flora. Composition analysis: The relative abundance of major bacterial phyla, genera and species is determined by taxonomic analysis.
Inflammatory factor3 monthsChanges in serum levels of inflammatory cytokines (IL-6, IL-1β, TNF-α, IP-10) : To evaluate the effect of the tested product on the inflammatory response and reflect the immune status of the body.
Fatty liver morphology3 monthsAbdominal B-ultrasound: To evaluate the effect of the tested product on the morphology of fatty liver, reflecting the liver fat deposition.
Fasting blood glucose3 monthsEvaluate the effect of the tested product on blood sugar levels. Fasting blood glucose: the unit is mmol/L.
High density lipoprotein (HDL)3 monthsThe effect of the tested product on lipid levels was evaluated. HDL: The unit is mmol/L.
