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.
Based on multiple meta-analyses with >3000 participants. Effects require concurrent resistance training. Benefits plateau around 30-40g per serving. Isolate forms may reduce digestive issues.
