About

A naturally occurring xanthine alkaloid and the world's most widely consumed psychoactive substance. Caffeine supports metabolic rate and fat oxidation through sympathetic nervous system activation. Extensively studied in clinical trials for its role in energy expenditure and exercise performance.

How It Works

Adenosine receptor antagonist that stimulates the sympathetic nervous system, increasing catecholamine release (epinephrine, norepinephrine). This activates hormone-sensitive lipase, mobilizing fatty acids from adipose tissue, and increases resting metabolic rate by 3-11%.
