RevGenetics EGCG 800, formulated by Anthony Loera, delivers 800mg of 98% pure, caffeine-free Epigallocatechin gallate (EGCG) sourced from premium Green Tea Extract (Camellia sinensis). Enhanced with RGBooster1, a patent-pending P-glycoprotein efflux modulator. This formula addresses the fundamental bioavailability barrier that renders standard green tea supplements ineffective at cellular concentrations.*
If Your Green Tea Extract Isn't Working, It's Not You. It's the P-gp Problem.
Epigallocatechin gallate has been studied in over 11,000 published papers. The research is compelling. Yet most people taking green tea supplements see minimal results. The reason isn't the compound. It's delivery. P-glycoprotein (P-gp) efflux pumps in your intestinal lining actively transport EGCG back into the gut lumen after it's absorbed into intestinal cells, dramatically reducing net absorption into your bloodstream. Standard EGCG bioavailability is between 0.1-1.68%. A typical 800mg capsule delivers as little as 1-13mg to your circulation.
RGBooster1 modulates these P-gp pumps at 300x the potency of standard piperine at this specific mechanism, allowing significantly more EGCG to cross the intestinal wall and reach your cells. And because we stripped the caffeine entirely, you can take a clinical dose without a single milligram of stimulant.*
What Our Customers Are Saying
"I wanted the longevity benefits of EGCG but I'm incredibly sensitive to caffeine. This formula has been perfect. I take it every morning with breakfast and I can feel the difference in my energy and focus."
"After reading the research on autophagy and cellular aging, I added this to my fasting protocol. The quality is exceptional and I trust RevGenetics' independent third-party testing."

From the Founder
"We didn't just want to create another green tea extract. We wanted to provide the exact, concentrated polyphenol dose used in longevity research, without the jitters. For 20 years I've watched the supplement industry ignore the absorption problem. By extracting 800mg of 98% pure EGCG and pairing it with RGBooster1 to modulate P-gp efflux pumps, we ensure your body actually absorbs what it needs to support healthy cellular aging."
What Is EGCG 800? The 3-Layer Bioavailability System
EGCG 800 is not a standard green tea pill. It is a precision-engineered cellular longevity compound that solves the three barriers preventing EGCG from working at clinical concentrations.
Layer 1: The Clinical Dose
We start with 800mg of Green Tea Extract (Camellia sinensis), standardized to 98% EGCG, yielding 784mg of pure Epigallocatechin-3-gallate per serving. This delivers the raw EGCG concentration used in peer-reviewed longevity research, equivalent to the EGCG content of over 80 cups of brewed green tea.*
Layer 2: The Absorption Engine, RGBooster1
Standard EGCG bioavailability is just 0.1-1.68%. P-glycoprotein (P-gp) efflux pumps in your intestinal lining cells transport absorbed EGCG back out into the gut lumen before it reaches systemic circulation. Most absorption enhancers use piperine (black pepper extract), which acts after absorption via CYP3A4 inhibition. RGBooster1 works earlier, directly at the P-gp pumps, at 300x the potency of piperine at this specific mechanism.*
The 80-Cup Math: One cup of green tea contains approximately 50mg of EGCG. At 1% standard bioavailability, that's just 0.5mg absorbed per cup. With 800mg raw EGCG and RGBooster1 P-gp modulation enhancing cellular uptake, each serving delivers the bioavailable equivalent of 80+ cups of standard green tea, without the caffeine.*
Layer 3: Stimulant-Free Formula
Achieving therapeutic EGCG doses through green tea or standard extracts means consuming dangerous levels of caffeine. EGCG 800 is rigorously decaffeinated: 0mg caffeine, allowing you to take a clinical daily dose without jitters, anxiety, heart palpitations, or sleep disruption. Take it morning, afternoon, or evening.
Who Is EGCG 800 For?
- Biohackers and Longevity Enthusiasts: Targeting cellular senescence, autophagy activation, and AMPK pathway support at clinical concentrations.*
- Intermittent Fasting Protocol Users: Supporting metabolic pathways during fasting windows without stimulants that disrupt fasted states.*
- Caffeine-Sensitive Individuals: People who want green tea's polyphenol benefits without the CNS stimulation, sleep disruption, or anxiety.

The Science of EGCG 800: 6 Targeted Benefits
1. Autophagy Activation*
The Result: Supports the body's natural cellular recycling and renewal process.
The Science: Preclinical research suggests EGCG activates autophagy pathways in laboratory and animal models by modulating the AMPK/mTOR axis, the same metabolic switches governing cellular cleanup processes [7]. Autophagy has been identified as a primary Hallmark of Aging [6].
2. Cellular Senescence Support*
The Result: Supports the body's natural clearance of aging, dysfunctional cells that drive age-related inflammatory signaling.
The Science: Preclinical research indicates EGCG may modulate pathways associated with cellular senescence and SASP (Senescence-Associated Secretory Phenotype) reduction in laboratory models [8].
3. Nrf2 Pathway Activation & Antioxidant Defense*
The Result: Activates the body's master antioxidant switch, boosting endogenous glutathione and superoxide dismutase (SOD) production.
The Science: A 2024 study confirmed EGCG activates the Nrf2/Keap1/P62 pathway, inhibiting oxidative iron deposition and supporting cellular antioxidant defense [8].
4. Metabolic Support & Fat Oxidation*
The Result: Supports healthy fat metabolism and metabolic efficiency.
The Science: Clinical research shows green tea catechins can increase fat oxidation by up to 17% during moderate exercise [1]. Green tea extract consumption is associated with healthy metabolic parameters across multiple studies [4].
5. Cardiovascular Health*
The Result: Supports healthy endothelial function and blood flow.
The Science: Green tea catechins are associated with improved endothelial health markers and vascular support in peer-reviewed clinical literature [3, 4].
6. Cognitive Support*
The Result: Supports cognitive function and long-term brain health.
The Science: In laboratory and animal models, EGCG has been shown to cross the blood-brain barrier. Human studies support green tea consumption for cognitive function in older adults [2].

EGCG 800 works through cellular and enzymatic pathways, not stimulant mechanisms. Results compound over time with consistent daily use.
- 4-8 Weeks: Initial support for metabolic pathways, antioxidant defense activation, and Nrf2 pathway engagement.*
- 60-90 Days: Deeper cellular aging benefits including autophagy support and cellular senescence pathway modulation.*
This is a cellular health supplement, not a medication. It does not replace any prescribed treatment. Consult your healthcare provider with questions about your personal health.
EGCG in Your Longevity Stack
EGCG 800 is a powerful standalone compound. It also works synergistically with other longevity molecules:
The Longevity Stack: EGCG + NMN + Resveratrol
Combines AMPK/sirtuin activation with NAD+ production for comprehensive cellular energy support. EGCG contributes Nrf2 activation and P-gp-enhanced polyphenol delivery.*
The Cellular Renewal Stack: EGCG + Quercetin or Fisetin
Adds complementary senolytic activity for advanced cellular housekeeping support.* Preclinical research suggests flavonoid combinations may have additive effects on senescent cell pathway modulation.
