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 limited RCT evidence (n=50) and systematic review findings. DGL form preferred to avoid aldosterone effects. Effectiveness estimates conservative given small study sizes.
AI-estimated from published studies. Interpret as directional guidance.
B-Complex has a higher evidence score (9/10 vs 6/10) and wins in 2 of 3 categories.
