Research Progress of Nattokinase in Reducing Blood Lipid
Nutrients (2025) · Systematic review
Large-scale clinical trials have confirmed that nattokinase significantly improves the lipid profile and reduces the atherosclerotic plaque area and intima-media thickness with a favorable safety profile.
Navigating the Effects of Anti-Atherosclerotic Supplements and Acknowledging Associated Bleeding Risks
International journal of molecular sciences (2025) · Systematic review
Omega-3 fatty acids, berberine, garlic, and nattokinase exert favorable metabolic and vascular effects, yet their clinical efficacy depends on formulation, dosage, and patient characteristics and may be limited by bleeding risk or drug interactions.
Fermented Fruits, Vegetables, and Legumes in Metabolic Syndrome: From Traditional Use to Functional Foods and Medical Applications
Nutrients (2025) · Systematic review
Fermented fruits and vegetables, including table olives, caper fruits, and kimchi, contain polyphenols and probiotic bacteria, which are beneficial in terms of obesity and impaired glucose and lipid metabolism.
Effects of Nutritional Supplements on Endurance Performance and Subjective Perception in Athletes Exercising in the Heat: A Systematic Review and Network Meta-Analysis
Nutrients (2025) · Meta analysis · n=552
Standardized mean differences (SMDs) and posterior probabilities (P-scores based on Bayesian ranking) were calculated using random-effects and Bayesian models.
Effect of a 12-mo intervention with whey protein powder on cognitive function in older adults with mild cognitive impairment: a randomized controlled trial
The American journal of clinical nutrition (2025) · Rct · n=107
The results also found a significant beneficial effect of the active intervention for several secondary cognitive outcomes such as Digit Symbol Substitution Test score, and the mean difference between groups in the ITT analysis was 2.72 (95% CI: 0.20, 5.23).
Caffeine and taurine: a systematic review and network meta-analysis of their individual and combined effects on physical capacity, cognitive function, and physiological markers
Journal of the International Society of Sports Nutrition (2025) · Meta analysis
Posterior estimates indicated that CAF+TAU was associated with a credible positive effect on anaerobic capacity (g = 0.46, 95% CrI [0.19, 0.71]) and reaction time (g = 0.75, 95% CrI [0.29, 1.18]) compared to CAF or TAU alone.
Based on fibrinolytic activity demonstrated in multiple studies. Conservative estimate given limited direct circulation measurements. One RCT (n=153) showed clinical symptom improvement. Bleeding risk may increase with dose due to fibrinolytic mechanism.
Based on meta-analysis showing small-to-moderate effects (g=0.25). Conservative estimates due to high heterogeneity (I²=61%) and mixed study quality. Effects primarily seen in anaerobic capacity and reaction time when combined with caffeine.
AI-estimated from published studies. Interpret as directional guidance.
Taurine has a higher evidence score (7.5/10 vs 6/10) and wins in 3 of 3 categories.
For support heart health, Nattokinase has a higher relevance score (88 vs 60).
No known interactions between Nattokinase and Taurine have been documented in our database. However, always consult a healthcare provider before combining supplements.
