The science behind fat-burning ingredients — what works, how it works, and why.
EGCG (epigallocatechin gallate) is the most bioactive catechin in green tea and one of the most extensively studied natural compounds for metabolism and weight management. Discover how it inhibits COMT, synergizes with caffeine, and activates fat oxidation pathways at the cellular level.
Bitter orange extract containing p-synephrine is the most widely studied natural thermogenic currently available. Unlike ephedra, synephrine is cardiovascularly selective and clinically safe. Discover the mechanisms, dose-response data, and clinical evidence supporting its fat-burning properties.
5-HTP (5-hydroxytryptophan) is the direct precursor to serotonin — the neurotransmitter that regulates mood, appetite, and sleep. Discover how this compound improves sleep architecture, reduces carbohydrate cravings, and supports healthy weight management through the serotonin pathway.
Milk thistle contains silymarin — one of the most clinically validated hepatoprotective compounds in natural medicine. Discover how it protects liver cells, stimulates regeneration, and supports fat metabolism through multiple mechanisms.
