Nutritional neuroscience (2023) · Systematic review · n=2256
Systematic review examining Thiamine efficacy
Based on meta-analysis showing OR 1.92 for clinical pregnancy rate in poor ovarian response patients. Effect specific to fertility treatment context with medical supervision. Limited long-term safety data.
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.
