Green Coffee Bean Extract — Clean, Sustained Caffeine

Found in: Focus by Of The Gods

Green coffee bean extract is derived from unroasted Coffea arabica or Coffea canephora beans, preserving the full spectrum of bioactive compounds that are substantially degraded during conventional roasting. While it serves as Focus's natural caffeine source, green coffee bean extract delivers more than stimulation — it is uniquely rich in chlorogenic acids (CGAs), a family of phenolic compounds with antioxidant, metabolic, and neuroprotective properties.†

Biochemical Profile & Mechanism of Action

• Caffeine (natural): The world's most widely consumed psychoactive compound. Caffeine blocks adenosine A₁ and A₂ₐ receptors in the brain, preventing the accumulation of sleep-signaling adenosine and maintaining wakefulness, alertness, and reaction speed. Focus contains approximately 35 mg of caffeine per serving — roughly the amount in a cup of green tea
• Chlorogenic acids (CGAs): Comprise up to 10% of unroasted green coffee by weight (compared to 1–2% in roasted coffee). CGAs inhibit glucose-6-phosphatase in the liver, modulating blood sugar response and providing a steadier energy curve. They also exhibit potent antioxidant activity, neutralizing reactive oxygen species (ROS)
• Ferulic acid & caffeic acid: CGA metabolites that cross the blood-brain barrier and exert independent neuroprotective and anti-inflammatory effects

Research-Supported Benefits

• Cognitive performance: Caffeine (in doses as low as 32 mg) reliably improves sustained attention, reaction time, and vigilance across dozens of meta-analyzed trials (McLellan et al., 2016).†
• Metabolic support: A meta-analysis of 13 randomized controlled trials concluded that green coffee extract supplementation significantly reduced body weight, BMI, and waist circumference compared to placebo, attributed primarily to CGA-mediated effects on glucose and fat metabolism (Onakpoya et al., 2011).†
• Antioxidant activity: Chlorogenic acids from green coffee significantly increased plasma antioxidant capacity and reduced markers of oxidative DNA damage in a human crossover trial (Hoelzl et al., 2010).†
• Blood pressure: A systematic review found that chlorogenic acids from green coffee extract significantly reduced systolic and diastolic blood pressure in mildly hypertensive subjects (Watanabe et al., 2006).†

Why It's in Focus

Green coffee bean extract provides a clean, low-dose caffeine source (~35 mg per serving) designed to be enhanced — not replaced — by the other compounds in the stack. L-Theanine smooths out the caffeine curve, L-Tyrosine replenishes the neurotransmitters caffeine mobilizes, and Magnesium Glycinate prevents the tension that higher caffeine doses can create. The result: sustained focus without jitters, crashes, or anxiety.†
