Green Tea & Guarana: What The Research Actually Shows

By the SodaFit Wellness Desk · · 6 min read

In Short

Green tea leaf extract and guarana seed extract, SodaFit's two thermogenic ingredients, both carry naturally occurring caffeine.

Here is what the research actually shows about these energy-focused ingredients.

What green tea and guarana actually do

Green tea provides catechins (notably EGCG) alongside natural caffeine, a combination studied for modest effects on thermogenesis and fat oxidation. Guarana seed contains a naturally higher caffeine concentration by weight than coffee beans, traditionally used for alertness and stamina.

Why the combination is common

A fair summary: pairing a caffeine source with catechins is a well-established combination in the thermogenic-supplement category, since some research suggests catechins and caffeine may work synergistically for modest fat-oxidation support during activity. This is a coherent formulation choice, not a scattershot one.

What the evidence supports

Modest, temporary increases in energy expenditure and alertness, generally at meaningful caffeine doses used in controlled studies.

What the evidence does not support

Neither ingredient is a guaranteed or dramatic fat-loss solution on its own, and results depend heavily on the actual caffeine dose delivered, which isn't disclosed in SodaFit's case.

Applying this to SodaFit

SodaFit doesn't publish the caffeine content per dropper from either source, so total caffeine intake (relevant for sensitivity, medication interactions, and pregnancy) can't be calculated from the label alone. See our full ingredient breakdown for the complete picture.
