What Is Red Yeast Rice (Cholesterol) & Why Does Form Matter?

Red Yeast Rice (Cholesterol) is classified under CARDIOVASCULAR and has been investigated across 30 peer-reviewed PubMed publications for its role in targeted physiological homeostasis, clinical biomarker modulation, and evidence-based nutritional support.

In clinical nutrition, physiological efficacy depends heavily on the specific chemical salt, chelate, or standardized extract used, as well as adherence to trial-validated dosing (1000 mg, 160 mg, 300 mg).

02

Who Benefits Most & Common Depletion Factors

Suboptimal status or increased physiological demand for Red Yeast Rice (Cholesterol) frequently arises from restrictive dietary patterns, age-related declines in gastrointestinal absorption, chronic metabolic stress, or medication-induced nutrient depletion.

Before initiating supplementation, identify whether your primary goal aligns with the endpoints evaluated in human randomized controlled trials (8 RCTs indexed) rather than generalized marketing claims.

03

Physiological Mechanism of Action

Within human physiology, Red Yeast Rice (Cholesterol) acts on pathways governing targeted physiological homeostasis, clinical biomarker modulation, and evidence-based nutritional support. Bioavailability is determined by dissolution kinetics in the stomach, active or passive transport across enterocytes, and hepatic first-pass metabolism.

Shared and Distinct Genetic Factors Underlying Bile Acid Regulation and Intrahepatic Cholestasis of Pregnancy.
Clinical Trial Synthesis 2026 Meta-Analysis published in Genetic epidemiology; statistical significance reported at p = 1.08. Key conclusion: We identified genome-wide significant associations at CYP7A1 (rs4738680, p = 1.08 × 10-10) and SLC39A9 (rs17107007, p = 3.46 × 10-28) for TBA, and at SLC39A9 (rs17107007, p = 3.34 × 10-16) for ICP.

Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disorder characterized by elevated total bile acid (TBA) levels, leading to adverse maternal and fetal outcomes. While genetic factors contribute to ICP and bile acid metabolism, the underlying mechanisms remain incompletely understood, particularly in East Asian populations. We conducted a genome-wide association study (GWAS) in 13,357 pregnant women from a Chinese cohort to investigate genetic determinants of TBA levels and ICP. Meta-analysis was performed by combining our data with the Shenzhen cohort. Post-GWAS analyses included pathway enrichment, integrative analysis with liver single-cell RNA sequencing (scRNA-seq) data, and Mendelian randomization (MR). We identified genome-wide significant associations at CYP7A1 (rs4738680, p = 1.08 × 10-10) and SLC39A9 (rs17107007, p = 3.46 × 10-28) for TBA, and at SLC39A9 (rs17107007, p = 3.34 × 10-16) for ICP. Pathway analysis highlighted bile acid synthesis and metabolism pathways for TBA and immune-related pathways for ICP. Integrative scRNA-seq analysis revealed enrichment of TBA-associated genes in hepatocytes and ICP-associated genes in neutrophils. MR analysis suggested a potential causal effect of estrone on TBA levels. Our findings provide novel insights into the genetic architecture of TBA and ICP, emphasizing the roles of bile acid metabolism in hepatocytes and immune dysregulation in ICP pathogenesis. The identified genetic loci and pathways may inform future research on risk prediction and targeted therapies for ICP. © 2026 Wiley Periodicals LLC.

View Original PubMed Abstract ↓

BACKGROUND: Postprandial triglyceride (TG) metabolism represents a dynamic dimension of lipid physiology that complements conventional fasting lipid assessment. Although low-density lipoprotein cholesterol (LDL-C) remains the primary therapeutic target in cardiovascular prevention, residual cardiovascular risk persists in many individuals despite apparently adequate fasting lipid control. Because most individuals spend the majority of their waking hours in a fed state, postprandial TG responses may provide clinically relevant insight into metabolic flexibility, dietary exposure, and the efficiency of TG-rich lipoprotein clearance. METHODS: This narrative review was conducted using a literature search guided by predefined themes, keywords, and databases, without following a formal systematic review protocol. Randomized controlled trials, observational studies, meta-analyses, and major reviews addressing postprandial lipid metabolism, dietary determinants, and cardiometabolic risk were included, with priority given to human studies. RESULTS: Postprandial TG responses are strongly influenced by dietary composition, eating patterns, and metabolic health. Individuals with insulin resistance, type 2 diabetes, obesity, and metabolic-associated steatotic liver disease (MASLD) frequently demonstrate exaggerated or prolonged postprandial lipemia even when fasting TG concentrations appear acceptable. While circulating TGs serve as practical clinical markers of postprandial lipid handling, cholesterol-enriched remnant lipoproteins more closely reflect atherogenic burden. Nutritional interventions, weight management, and physical activity consistently improve postprandial TG dynamics, whereas pharmacologic therapy provides additional benefit in selected high-risk patients. Non-fasting TG measurements may provide additional insight into postprandial lipid metabolism and residual cardiovascular risk, although standardized protocols and validated clinical thresholds remain to be established. CONCLUSIONS: Postprandial TG metabolism provides clinically meaningful information beyond fasting lipid measurements and represents a useful adjunct for refining residual cardiovascular ris

PURPOSE: Evidence regarding sources of heterogeneity in the efficacy of statins for primary prevention of cardiovascular disease (CVD) remains limited. This study aimed to identify trial-level factors contributing to such heterogeneity. METHODS: Relevant studies were systematically identified from a previous systematic review and through searches in PubMed, Embase, and Cochrane up to 20 January 2026. The protocol was registered in PROSPERO (CRD42024579932). Randomized controlled trials (RCTs) in adults without prior CVD that investigated statin treatment were included. Risk of bias was assessed using the Cochrane Risk of Bias tool. Meta-analyses were conducted to pool risk ratios (RRs) and 95% confidence intervals (CIs) for major adverse cardiovascular events (MACE), myocardial infarction (MI), stroke, and cardiovascular death. Univariate meta-regression analyses were conducted to assess the impact of trial-level covariates on the effect sizes, expressed as the ratio of risk ratios (RRR). Within-study subgroup differences were meta-analyzed by pooling ratio of effect sizes. Meta-regression analyses were conducted using complete-case trial-level data. RESULTS: 25 RCTs (102,667 participants) were included. Compared to no statin treatment, statin treatment was associated with a reduced risk of MACE (RR, 0.73[95% CI, 0.67 to 0.80], P < 0.001), MI (RR, 0.68[95% CI, 0.60 to 0.77], P < 0.001), stroke (RR, 0.76[95% CI, 0.65 to 0.89], P = 0.001) and cardiovascular death (RR, 0.81[95% CI, 0.71 to 0.95], P = 0.008). Univariate meta-regression indicated that higher baseline total cholesterol (RRR, 1.29 [95% CI, 1.07 to 1.57], P = 0.008), higher low-density lipoprotein cholesterol (LDL-C) (RRR, 1.31 [95% CI, 1.07 to 1.62], P = 0.010), higher triglycerides (RRR, 1.81 [95% CI, 1.17 to 2.81], P = 0.008) and lower statin intensity (RRR, 0.74 [95% CI, 0.59 to 0.94], P = 0.015) were significantly associated with reduced efficacy of statins for stroke prevention at the trial level.

BACKGROUND: Prediabetes is a growing global health concern. Lifestyle modification is the cornerstone of management, yet scalable delivery strategies are needed. SMS text messaging is a promising mobile health approach for behavior change, but its effectiveness for metabolic outcomes in prediabetes remains uncertain. OBJECTIVE: This study aims to evaluate the effectiveness of text message-delivered lifestyle programs for BMI among adults with prediabetes and, secondarily, for weight, waist circumference, hemoglobin A1c (HbA1c), total cholesterol, and diabetes incidence. METHODS: We conducted a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-guided systematic review and meta-analysis of randomized controlled trials (searching the PubMed, MEDLINE, CINAHL, Embase, Web of Science, and the Cochrane Library databases; from April 2005 to March 2025). Three reviewers independently screened studies, extracted data, and assessed risk of bias (using the Cochrane Risk of Bias tool), and random-effects meta-analyses were performed. RESULTS: In total, 7 randomized controlled trials (n=4632) met the inclusion criteria. SMS text messaging did not significantly affect BMI compared with standard care (mean difference [MD] -0.17 kg/m², 95% CI -0.85 to 0.25; I²=32%). Secondary outcomes were similarly nonsignificant: weight (MD -0.46 kg, 95% CI -1.74 to 0.83; I²=27%); waist circumference (MD -0.36 cm, 95% CI -1.09 to 0.36; I²=13%); HbA1c (MD -0.05%, 95% CI -0.17 to 0.07; I²=89%); total cholesterol (standardized MD -0.00, 95% CI -0.06 to 0.06; I²=0%); and diabetes incidence (odds ratio 0.84, 95% CI 0.63-1.12, I²=51%; n=3515 across 3 trials). Estimates were small and, for several outcomes, notably HbA1c and diabetes incidence, were imprecise and heterogeneous, indicating substantial between-study variability. CONCLUSIONS: In adults with prediabetes, lifestyle programs incorporating SMS text messaging showed no meaningful effect on BMI or other metabolic outcomes; pooled estimates were near null with considerable uncertainty and heterogeneity for some end points. Variability in intervention design, dose, and tailoring likely contributed to these results. Fut

View Original PubMed Abstract ↓

BACKGROUND: Kudzu root is commonly prescribed in traditional Chinese medicine for non-alcoholic fatty liver disease (NAFLD). Its key active ingredient, puerarin, has shown promising protective effects in experimental NAFLD models. Yet the overall efficacy and the main biological mechanisms have not been systematically assessed. OBJECTIVE: This meta-analysis will synthesize evidence from animal studies to determine how puerarin influences liver-related outcomes in NAFLD. It will also summarize the mechanistic pathways that may account for these effects. METHOD: Literature retrieval was performed up to September 2025, encompassing eight databases. The risk of bias in the included studies was evaluated using the SYRCLE assessment tool. Data analyses were then performed in Stata 15. The primary outcome included triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT), and aspartate aminotransferase (AST). Secondary outcome comprised interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNF-α), superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px). Subgroup analyses, publication bias assessments, and sensitivity analyses were performed to ensure the robustness. RESULTS: 20 studies were included, involving 331 animals. Puerarin treatment significantly reduced levels of TG, TC, and LDL-C, while improving HDL-C in animal models of NAFLD. Additionally, puerarin significantly upregulated antioxidant indicators SOD and GSH-Px and lowered MDA levels. Furthermore, it inhibited the expression of inflammatory factors IL-6, IL-1β, and TNF-α. CONCLUSION: This meta-analysis concludes that puerarin demonstrates substantial liver-protective effects in NAFLD models by regulating lipid metabolism, anti-inflammatory, and antioxidant. Collectively, these finding lays a solid evidence-based foundation for the subsequent advancement of clinical translation research and the in-depth exploration of its underlying mechanisms.

INTRODUCTION: Ischemic stroke (IS) exhibits pronounced geographic variation across China, with a consistently greater burden observed in colder regions. However, whether the strength of associations between major risk factors and IS differs between cold and non-cold regions remains unclear. METHODS: We systematically searched observational studies in PubMed, Embase, Web of Science, CNKI, Wanfang, VIP, and CBM from inception through September 6, 2025. Data were analyzed using Stata 16.0. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Regional differences were evaluated using subgroup analysis. RESULTS: Ninety-six studies involving 800,741 participants were included. In the overall analysis, the largest pooled effect estimates were observed for atrial fibrillation (OR 4.48, 95% CI 2.41-8.36, I2 = 62.1%), coronary heart disease (OR 3.20, 95% CI 2.29-4.46, I2 = 86.2%), and hypertension (OR 3.05, 95% CI 2.55-3.64, I2 = 92.9%), all of which were accompanied by moderate to substantial between-study heterogeneity. Subgroup analysis demonstrated significantly larger pooled associations in cold regions for hypertension (OR 4.31 vs. 2.69, I2 = 94.8% vs. 92.0%), diabetes mellitus (OR 2.60 vs. 1.77, I2 = 71.6% vs. 90.7%), triglycerides (OR 3.41 vs. 1.48, I2 = 96.7% vs. 92.4%), and low-density lipoprotein cholesterol (OR 1.91 vs. 1.43, I2 = 0.0% vs. 67.2%) (all p < 0.05). In contrast, age was more strongly associated with IS in non-cold regions (OR 1.31 vs. 1.05, I2 = 91.4% vs. 91.8%). CONCLUSION: Our analysis identified substantial geographic heterogeneity in the reported associations between selected cardiometabolic risk factors and IS in China. These exploratory, study-level findings generate hypotheses regarding contextual modification of risk factor associations, warranting confirmation in prospective, individual-level studies before informing region-specific prevention strategies. © 2026 S.

OBJECTIVE: Currently, effective drugs for metabolic dysfunction-associated steatotic liver disease (MASLD) are limited, with treatment primarily focusing on diet and exercise. Recent studies suggest that gut microbiota-regulating drugs may offer therapeutic benefits. Therefore, our aim is to evaluate the efficacy of these medications in MASLD patients. METHODS: This systematic review and network meta-analysis involved a search of PubMed, Web of Science, Embase, Cochrane Library, and ClinicalTrials.gov for randomized controlled trials (RCTs) published from January 1, 2012, to January 28, 2026. The intervention measures encompassed probiotics, prebiotics, synbiotics, antibiotics, postbiotics, and a combination of antibiotics and gut microbiota-regulating drugs. The control group received a placebo or usual care. The risk of bias in the included research was evaluated utilizing the revised Cochrane risk of bias tool for randomised trials. The confidence of evidence will be evaluated through the CINeMA (Confidence in Network Meta-Analysis) web application. Liver enzymes and hepatic steatosis were taken as the primary outcome and were analyzed by random-effects, Bayesian network meta-analyses. A two stage network meta-analysis harnessing the surface under the cumulative ranking curve (SUCRA) was performed for assessing the comparative efficacy of medications classes and particular gut microbiota-regulating drugs. The study was registered on PROSPERO: CRD42024606333. RESULTS: A total of 27 studies comprising 1,511 participants were included in this meta-analysis. Relative to placebo, reductions in alanine aminotransferase (ALT) levels were observed with probiotics (Mean Difference (MD): -7.51, 95% credible intervals (CI) [-12.36 to -2.66]), prebiotics (MD: -13.64, 95% CI [-27.07 to -0.22]) and antibiotics (MD: -24.30, 95% CI [-47.02 to -1.58]). Probiotics (MD: -6.42, 95% CI [-11.91 to -0.92]) and synbiotics (MD: -13.13, 95% CI [-20.82 to -5.45]) were both associated with a reduction in aspartate aminotransferase (AST) levels compared to placebo.

View Original PubMed Abstract ↓

BACKGROUND AND AIMS: Familial hypercholesterolemia (FH) is a highly prevalent monogenic disorder characterized by elevated low-density lipoprotein-cholesterol (LDL-C) levels and premature atherosclerotic cardiovascular disease (ASCVD). The risk factors associated with cardiovascular events in this population vary considerably among studies. This systematic review aims to identify the key risk factors predicting cardiovascular events in patients with a confirmed genetic diagnosis of heterozygous FH (PROSPERO, CRD42022304273). METHODS AND ANALYSIS: Cochrane Library, Embase, MEDLINE, Scopus, UpToDate and other literature databases were searched from inception to June 2023. Records were eligible if they included studies reporting risk factors for ASCVD endpoints in adult patients with a genetic diagnosis of FH. A meta-analysis was performed using MetaEasy. RESULTS: A total of 21 studies were identified, involving 23,613 individual participants and 3489 prevalent cardiovascular events. The sex distribution was 47.2% male and 52.8% female. Most of the studies were conducted in European populations, representing 90.5% of the total. The meta-analysis found associations between ASCVD and hypertension (effect size 0.414; 95% CI: 0.346-0.482), male sex (0.334; 0.213-0.456), smoking (0.324; 0.203-0.445), lipoprotein(a) (0.219; 0.127-0.312), age (0.212; 0.161-0.264), body mass index (0.108; 0.028-0.188), triglycerides (0.084; 0.057-0.111) and LDL-C (0.015; 0.002-0.028). CONCLUSIONS: This is the first systematic review and meta-analysis demonstrating that hypertension, male sex, smoking, lipoprotein(a), age, body mass index, triglycerides and LDL-C are significantly and independently associated with ASCVD in genetically confirmed patients with heterozygous FH. These data can inform risk stratification models and optimise therapy in such patients.

BACKGROUND: Dihydromyricetin (DHM) is a food-derived flavonoid widely investigated as a nutraceutical candidate for metabolic dysfunction-associated steatotic liver disease (MASLD) in preclinical models; however, its overall efficacy in diet-induced MASLD/NAFLD models has not been systematically quantified. METHODS: This PRISMA 2020 systematic review and meta-analysis was registered in PROSPERO (CRD420251119087). PubMed, Embase, Web of Science Core Collection, the Cochrane Library, and four major Chinese databases were searched from inception to December 15, 2025. Controlled murine studies comparing DHM monotherapy with high-fat diet controls were included. Random-effects meta-analyses pooled standardized mean differences (SMDs) with 95% confidence intervals; risk of bias was assessed using SYRCLE's tool. RESULTS: Fourteen controlled studies were included. Compared with controls, DHM reduced hepatic triglycerides and total cholesterol, improved liver enzymes (ALT, AST, ALP), and decreased body weight and liver index. DHM improved serum lipid profiles (lower total cholesterol and LDL; higher HDL) and glucose homeostasis (lower fasting glucose and insulin). Antioxidant defenses increased (SOD, CAT, GSH, GSH-Px) with reduced malondialdehyde, while inflammatory markers (TNF-α and IL-6) decreased. At the signaling level, DHM increased the pAMPK/AMPK ratio. Heterogeneity was moderate to high for several outcomes, partly explained by dose and treatment duration. CONCLUSION: In murine diet-induced MASLD/NAFLD models, DHM shows promising multidomain benefits across various physiological outcomes, though some variability remains due to differences in study design. More standardized preclinical designs and well-controlled nutraceutical/clinical studies are needed to define clinically relevant, bioavailable dosing and efficacy.

METHODS: We searched the randomized controlled trials from 1948 to February 1, 2026 involving vitamin D supplementation treatment for patients with metabolic syndrome from PubMed, EMBASE, Cochrane library, SinoMed, and conducted a meta-analysis. The meta-analysis was registered on the PROSPERO, the registration number is CRD42024591657. RESULTS: Finally, seven trials were included in the meta-analysis. The results demonstrated that vitamin D supplementation significantly reduced triglyceride levels (MD = -12.64, 95% CI [-21.23∼-4.04], P = 0.004). However, no significant differences were observed in total cholesterol or low-density lipoprotein cholesterol levels between the vitamin D treated groups and control groups. Notably, vitamin D supplementation showed potential benefits in increasing high-density lipoprotein cholesterol levels particularly with daily regimens (MD = 1.77, 95% CI [0.90∼2.64] P < 0.0001, I2 = 35%). CONCLUSIONS: Our meta-analysis confirmed the effects of vitamin D in the management of triglyceride level in metabolic syndrome patients. Vitamin D supplementation showed potential benefits on increasing the high-density lipoprotein cholesterol levels especially with daily regimens. More randomized controlled trials are needed to confirm the result. ©2026 Wang et al.
