Capsaicin for Fat Oxidation Enhancement

B Good Evidence At least one randomized trial supports this, with mostly consistent results.

Meta-analysis of 12 RCTs (n=563) found capsaicinoids significantly increase energy expenditure by approximately 50 kcal/day and reduce appetite. Six mg/day may support modest fat oxidation increases. Non-pungent capsinoids show similar but milder effects.
