Short answer: EGCG's thermogenic role and Berberine's glucose-metabolism role work through different, well-documented mechanisms, together forming the formula's metabolic support core.
Why these two roles are genuinely complementary, not overlapping
Thermogenesis addresses calorie utilization directly, while glucose metabolism addresses a separate, connected metabolic pathway — two distinct angles on the same broad goal.
Why this pairing anchors the formula's central metabolic claim
Metabolic and thermogenic support (EGCG, Berberine) is listed first among the formula's three stated roles — reflecting its central, primary positioning.
💡 Worth knowing: this pairing is specifically why Berberine and EGCG are the formula's two most safety-sensitive ingredients — genuine potency comes with genuine caution.
