Efficacy of B-vitamins and vitamin D therapy in improving depressive and anxiety disorders: a systematic review of randomized controlled trials
Nutritional neuroscience (2023) · Systematic review · n=2256
Systematic review examining Thiamine efficacy
Large meta-analyses show minimal to nonexistent benefits. Effects appear modest at best, with significant study heterogeneity. Combination with glucosamine may be more effective than chondroitin alone.
Based on limited RCT evidence showing VAS pain reduction with B-vitamin combinations. Effect magnitude conservative due to mixed statistical significance. Higher bioavailability forms like benfotiamine likely more effective than standard thiamine HCl.
AI-estimated from published studies. Interpret as directional guidance.
Chondroitin has a higher evidence score (9/10 vs 9/10) and wins in 1 of 3 categories.
