Nutritional neuroscience (2023) · Systematic review · n=2256
Systematic review examining Thiamine efficacy
Based on meta-analysis of 1002 stroke patients, but showed non-significant increase in death at one month. Evidence is limited and mixed. Conservative effectiveness estimates due to safety concerns.
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.
