Short answer: Cayenne Pepper Fruit Extract is included for its association with mild thermogenesis — the body's natural calorie-burning process through heat production.
Why "mild" is a deliberately modest, honest qualifier
This direct word choice avoids overstating cayenne's contribution — a genuine, but modest, addition rather than the formula's primary mechanism.
Why cayenne is used in small doses specifically
Commonly used in small doses in metabolism-support formulas — a specific, honest framing distinguishing this ingredient's supporting role from the two primary ingredient groups (ACV and BHB).
💡 Worth knowing: this ingredient rounds out the formula's metabolic support alongside its two more central ingredients.
