Dosage exploration of combined B-vitamin supplementation in stroke prevention: a meta-analysis and systematic review
The American journal of clinical nutrition (2024) · Meta analysis · n=76664
In areas without and with partial folic acid fortification, combined B-vitamin supplementation significantly reduced the risk of stroke by 34% [RR: 0.66; 95% confidence interval (CI): 0.50, 0.86] and 11% (RR: 0.89; 95% CI: 0.79, 1.00), respectively.

Nutrients (2019) · Meta analysis · n=2015
Regarding individual facets of mood, B vitamin supplementation benefited stress (n = 958, SMD = 0.23, 95% CI = 0.02, 0.45, p = 0.03).
Effects of a food supplement containing phosphatidylserine on cognitive function in Chinese older adults with mild cognitive impairment: A randomized double-blind, placebo-controlled trial
Journal of affective disorders (2025) · Rct · n=190
A total of 190 participants (mean [SD] age, 67.95 [5.62] years; 70 (36.8 %) male and 120 (63.2 %) female) were randomized to the placebo group (n = 95) and intervention group (n = 95).
Dynamic release of extracellular particles after opening of the blood-brain barrier predicts glioblastoma susceptibility to paclitaxel
Nature communications (2025) · Rct
Thus, our study introduces an efficient microfluidic platform for the capture of circulating GBM EVPs and demonstrates that release upon BBB opening is predictive of outcomes following paclitaxel treatment.
Prognostic potential of lipid profiling in cancer patients: a systematic review of mass spectrometry-based studies
Lipids in health and disease (2024) · Systematic review · n=38
In conclusion, the potential for developing lipidomics in cancer prognostic prediction was demonstrated.
Multiple meta-analyses show small but statistically significant benefits for cognitive function in older adults and stroke prevention populations. Effect sizes are modest (SMD ~0.15-0.18). Benefits may be more pronounced in B-vitamin deficient populations.
Based on RCT in 190 Chinese older adults with mild cognitive impairment and systematic review of neuronutrients. Limited by small number of direct studies and population-specific findings.
