Energy balance

Acute ingestion of capsinoids (1–12 mg) does not significantly increase resting metabolic rate or fat oxidation in healthy human subjects within a 2-hour window.

Taking capsinoids (1-12 mg) will not increase your calorie burn or fat oxidation in the short term (2 hours). Do not rely on this supplement for immediate weight loss or metabolic boosting effects.
