Raspberry ketones are natural phenolic compounds found in red raspberries. They have been studied for how they interact with adiponectin, a hormone involved in regulating fatty acid metabolism, and the research points to support for the body's fat oxidation signaling pathways. In this formula they pair with green tea and caffeine anhydrous for a stacked thermogenic effect.*

Green tea extract is standardized for catechins, particularly EGCG, which research shows can inhibit the enzyme that breaks down norepinephrine. Norepinephrine signals fat cells to release stored fat, so keeping more of it active longer is meaningful for thermogenic support. It is one of the most studied botanical ingredients in the metabolism space, with a consistent mechanism and a strong safety record at standard doses.*

This is not the same as drinking coffee. Roasting destroys most of the chlorogenic acid in coffee beans, which is the compound researchers are most interested in for metabolism support. Green coffee bean extract skips the roast and preserves that chlorogenic acid, which has been studied for effects on glucose absorption and fat metabolism. It also contributes a modest amount of caffeine to the formula.*

The rind of the Garcinia cambogia fruit contains hydroxycitric acid (HCA), which has been studied for its effects on an enzyme involved in fat synthesis and for its influence on serotonin pathways tied to appetite regulation. It gives this formula an appetite-signaling dimension that the thermogenic ingredients alone do not cover.*

Caffeine anhydrous is the concentrated, powdered form of caffeine. It absorbs faster than caffeine from brewed beverages and is the most extensively studied thermogenic ingredient available. In this formula it works on its own as a thermogenic and amplifies what the green tea and raspberry ketones are doing through overlapping mechanisms. This product contains caffeine from three sources total, so if you are sensitive, check with your healthcare professional first.
