Green tea extract is the quiet second ingredient in most fat-burners, and the pairing with caffeine is not accidental.
What catechins are
Catechins are polyphenol antioxidants, and the most studied is epigallocatechin gallate, or EGCG. In an extract they are concentrated far beyond what a cup of brewed tea delivers, which is why the supplement form is used rather than simply drinking more tea.
The metabolic mechanism
EGCG inhibits catechol-O-methyltransferase, the enzyme that breaks down noradrenaline. Slowing that breakdown means the fat-mobilising signal persists longer. This is the specific reason catechins and caffeine are paired: caffeine raises the signal, EGCG keeps it circulating. Each is modest alone and the combination is consistently better studied than either in isolation.

Get SodaSlim — From $49The antioxidant side
Raised metabolic activity increases oxidative load, so an antioxidant running alongside a thermogenic is a sensible design choice rather than label decoration. Catechins also carry general cardiovascular and cellular support in the wider literature, though those are separate from any weight claim.
Practical notes
Green tea extract contributes its own caffeine on top of any anhydrous dose, so count it when totalling intake. Very high-dose isolated extracts have been associated with liver stress in rare cases, which is an argument for standard supplement doses like those in SodaSlim rather than megadosing an isolated EGCG product.
