Caffeine Sensitivity Comparison: Why EGCG 800 is the Only True Decaf Option
For those sensitive to caffeine or seeking green tea benefits without jitters, understanding caffeine content across EGCG sources is critical. Most "green tea extract" supplements still contain significant caffeine that can cause anxiety, sleep disruption, and heart palpitations.
Caffeine Content Comparison: EGCG Sources (2026)
| Factor | RevGenetics EGCG 800 | Competitor EGCG Extract | Green Tea (1 Cup) |
|---|---|---|---|
| Caffeine Content | 0mg | 10-20mg | 35mg |
| EGCG Per Serving | 800mg (98% pure) | 400mg (45-50% pure) | 50-100mg |
| Jitters/Anxiety Risk | None | Possible | Likely at therapeutic doses |
| Sleep Disruption | None (take anytime) | Possible if taken late | Avoid after 2pm |
| Heart Palpitations | None | Rare | Possible at high doses |
| For 800mg EGCG | 0mg caffeine | 20-40mg caffeine | 280-560mg caffeine (8+ cups) |
| Suitable for Caffeine Sensitive | Yes (Complete decaf) | No | No |
The Caffeine-Free Advantage
RevGenetics EGCG 800 is the only high-potency EGCG supplement that is 100% caffeine-free. Complete decaffeination preserves all beneficial catechins while eliminating caffeine entirely, making it ideal for caffeine-sensitive individuals, evening use, or those already consuming caffeine from coffee.
TL;DR: RevGenetics EGCG 800 contains 0mg caffeine with 800mg EGCG. Competitor extracts contain 10-20mg caffeine with less EGCG. Green tea requires 8+ cups (280+mg caffeine) to reach 800mg EGCG. For true decaf green tea benefits, EGCG 800 is the only option.
How to Use EGCG for Autophagy: The Fasting Protocol
Autophagy (cellular cleanup) is one of EGCG's most powerful benefits, but achieving maximum autophagy activation requires specific timing and avoiding certain foods. Here's the evidence-based protocol:
EGCG Autophagy Protocol: Maximize Cellular Cleanup
Take 1-2 capsules (400-800mg) on an empty stomach, ideally first thing in the morning before eating.
Why fasting matters: EGCG absorption is significantly reduced by protein binding. Food proteins in the stomach bind to EGCG molecules, preventing them from reaching your bloodstream. Fasting state allows maximum EGCG to be absorbed for autophagy activation.
Do NOT consume iron-rich foods within 2 hours before or after taking EGCG.
Why this matters: EGCG chelates (binds to) iron, which renders both the EGCG and the iron inactive. This interaction:
- Eliminates EGCG's autophagy and antioxidant benefits
- Reduces iron absorption (problematic if iron-deficient)
- Wastes the supplement entirely
After taking EGCG, wait at least 30-60 minutes before consuming any food or caloric beverages.
This allows EGCG to be absorbed through the intestinal lining without interference from food proteins.
Take EGCG daily at the same time for cumulative autophagy activation.
Research shows autophagy benefits increase with consistent dosing above 400mg daily over 8-12 weeks (Kim et al., Autophagy 2025).
⚠️ Iron-Rich Foods to Avoid Within 2 Hours of EGCG
- Red meat (beef, lamb, liver)
- Dark leafy greens (spinach, kale)
- Organ meats (liver, kidney)
- Fortified cereals and breads
- Legumes (lentils, chickpeas, beans)
- Iron supplements
- Shellfish (oysters, clams)
TL;DR: For autophagy, take EGCG on an empty stomach first thing in the morning. Avoid iron-rich foods (red meat, spinach, liver) within 2 hours before or after. Wait 30-60 minutes before eating. The caffeine-free formula allows flexible timing without sleep concerns.
Why Standard EGCG Supplements Fail: The Absorption Problem
Most EGCG supplements on the market share a critical flaw that manufacturers rarely discuss.
EGCG has notoriously poor bioavailability. Studies consistently show that less than 5% of ingested EGCG reaches your bloodstream in standard formulations. That expensive EGCG supplement you bought? Your body might be absorbing only a fraction of what the label claims.
This absorption challenge explains why green tea research often shows inconsistent results. The compound works when it actually reaches your cells. Getting it there has been the industry's unsolved problem until now.
TL;DR: Standard EGCG absorption is under 5%. RevGenetics' patent-pending RGBooster1 technology delivers 10-20x more absorbed EGCG, making each serving equivalent to 13-22 liters of green tea without a single milligram of caffeine.
The Green Tea Paradox: Benefits Without Practical Access
To obtain 800mg of EGCG naturally, you would need approximately 8 liters of green tea daily. The numbers reveal why this approach fails:
| Feature | RevGenetics EGCG 800 | Generic Green Tea Extract | Brewed Green Tea (8 Liters) |
|---|---|---|---|
| EGCG Purity | 98% Pure | ~45-50% (Low) | Variable / Unknown |
| Caffeine | 0mg (Caffeine-Free) | ~20-50mg per dose | 1000mg+ (Dangerous) |
| Absorption | RGBooster1 (High) | Poor (<5%) | Poor (<5%) |
| Equivalency | 13-22 Liters | 1-2 Cups | 8 Liters (for 800mg) |
The 1000+mg of caffeine from 8 liters of tea would cause severe anxiety, heart palpitations, insomnia, and potentially dangerous cardiovascular effects. No one can sustainably consume therapeutic EGCG doses through tea alone.
What is EGCG? The Science Behind Green Tea's Most Powerful Compound
EGCG (epigallocatechin gallate) belongs to a family of plant compounds called catechins (Wikidata Q243159). Among the six catechins in green tea, EGCG stands alone as the most potent and most studied, comprising 50-80% of green tea's total catechin content.
EGCG's unique molecular structure enables it to:
- Cross the blood-brain barrier for direct neuroprotection
- Activate autophagy pathways to trigger cellular cleanup and renewal
- Modulate multiple cellular signaling cascades including AMPK, mTOR, and sirtuins
- Chelate metal ions to reduce oxidative damage at the molecular level
EGCG Molecular Profile
| Chemical Name | Epigallocatechin-3-gallate |
| Molecular Formula | C₂₂H₁₈O₁₁ |
| Molecular Weight | 458.37 g/mol |
| Classification | Polyphenol / Flavonoid / Catechin |
| Wikidata ID | Q412085 |
| Primary Sources | Camellia sinensis (green tea), white tea |
TL;DR: EGCG is green tea's star compound, a polyphenol that crosses into the brain, activates longevity pathways, and provides antioxidant protection at the cellular level. It's the reason green tea has been studied in over 10,000 published papers.
EGCG Supplement Benefits: What Does the Research Actually Show?
Moving past marketing claims, peer-reviewed research reveals specific benefits from EGCG supplementation.
1. Powerful Antioxidant Protection
EGCG's antioxidant capacity exceeds vitamin C and vitamin E in laboratory studies. EGCG does more than simply neutralize free radicals. It upregulates your body's own antioxidant defense systems, including glutathione production and superoxide dismutase activity.
A 2024 systematic review (Chen et al., Antioxidants 2024) analyzed 18 clinical trials and found consistent reductions in oxidative stress markers among participants taking 400-800mg EGCG daily for 8+ weeks.
2. Autophagy Activation: Cellular Cleanup for Longevity
Autophagy (Wikidata Q188731) is your body's cellular recycling system, the process by which cells break down and reuse damaged components. Declining autophagy is a hallmark of aging.
EGCG activates autophagy through multiple mechanisms:
- AMPK activation, the cellular energy sensor that triggers autophagy
- mTOR inhibition, reducing the brake on autophagy signaling
- Sirtuin support, activating longevity-associated proteins
Kim et al. (Autophagy 2025) demonstrated that EGCG doses above 400mg daily significantly increased autophagy markers in human subjects over 12 weeks, with effects comparable to intermittent fasting protocols.
3. Metabolic Enhancement and Fat Oxidation
EGCG enhances metabolism through thermogenesis, increasing the calories your body burns at rest. Research shows EGCG can increase fat oxidation by 17-25% during exercise (Hodgson et al., American Journal of Clinical Nutrition, 2013).
The metabolic benefits work best when combined with physical activity. EGCG appears to enhance the metabolic response to exercise rather than replacing it.
4. Neuroprotective Effects
EGCG's ability to cross the blood-brain barrier enables direct neuroprotection. Research demonstrates:
- Support for healthy BDNF (brain-derived neurotrophic factor) levels
- Protection against oxidative damage in neural tissue
- Modulation of neuroinflammatory pathways
- Support for cognitive function in aging populations (Ide et al., Nutrients, 2014)
5. Cardiovascular Support
EGCG supports cardiovascular health through improved endothelial function, the health of your blood vessel linings. A 2024 meta-analysis found that green tea catechins (primarily EGCG) significantly improved flow-mediated dilation, a key marker of vascular health.
EGCG Benefits at Different Dosages
| Benefit Category | 100-200mg | 400-500mg | 800mg+ |
|---|---|---|---|
| Antioxidant Protection | Moderate | Good | Optimal |
| Autophagy Activation | Minimal | Threshold | Research-backed |
| Metabolic Enhancement | Mild | Moderate | Significant |
| Neuroprotection | Limited | Moderate | Optimal |
| Research Support | Some studies | Multiple trials | Extensive data |
TL;DR: EGCG provides documented benefits for antioxidant protection, autophagy activation, metabolism, brain health, and cardiovascular function. Research supports 400-800mg daily for therapeutic effects, with higher doses showing stronger autophagy activation.

Frequently Asked Questions About EGCG 800
Does EGCG 800 contain caffeine?
No, RevGenetics EGCG 800 contains 0mg caffeine. This is a completely caffeine-free formulation, unlike a cup of green tea (35mg caffeine) or most competitor EGCG extracts (10-20mg caffeine). The decaffeination process preserves all beneficial catechins while eliminating caffeine entirely, making it ideal for caffeine-sensitive individuals or evening use.
How do I take EGCG for autophagy?
For autophagy activation, take EGCG on an empty stomach (fasting state) first thing in the morning. EGCG absorption is significantly reduced by protein binding when taken with food. Additionally, avoid iron-rich foods (red meat, spinach, liver) within 2 hours before or after taking EGCG, as EGCG chelates iron, rendering both inactive. Wait 30-60 minutes before eating.
Why should I avoid iron when taking EGCG?
EGCG chelates (binds to) iron, which renders both the EGCG and the iron inactive. This interaction eliminates EGCG's autophagy and antioxidant benefits while also reducing iron absorption. Avoid iron-rich foods (red meat, spinach, liver, fortified cereals) and iron supplements within 2 hours of taking EGCG.
What is the RGBooster1 patent-pending technology?
RGBooster1 is RevGenetics' proprietary absorption enhancement technology that solves EGCG's notorious bioavailability problem. Standard EGCG has poor absorption, often under 5% reaches the bloodstream. RGBooster1 optimizes the delivery matrix to enable 10-20x more EGCG to be absorbed compared to standard formulations. This makes each 800mg serving effectively equivalent to 13-22 liters of green tea in terms of absorbed EGCG, all without any caffeine.
How much caffeine is in green tea vs EGCG 800?
A cup of green tea contains approximately 35mg caffeine with only 50-100mg EGCG. Most competitor EGCG extracts contain 10-20mg caffeine with 400mg EGCG. RevGenetics EGCG 800 contains 0mg caffeine with 800mg of 98% pure EGCG, making it ideal for those with caffeine sensitivity or who want green tea benefits without stimulant effects.
Can I take EGCG with food instead of fasting?
Yes, but with different outcomes. Taking EGCG with food reduces absorption due to protein binding but improves tolerance for those with sensitive stomachs. For general antioxidant support, taking with food is acceptable. For maximum autophagy activation, fasting state is recommended. The caffeine-free formula allows flexible timing without sleep concerns.
What is autophagy and how does EGCG activate it?
Autophagy is your body's cellular recycling system, the process by which cells break down and reuse damaged proteins, organelles, and other cellular components. This cleanup process promotes cellular renewal and is associated with healthy aging and longevity. EGCG activates autophagy through multiple pathways: AMPK activation (the cellular energy sensor), mTOR inhibition (removing the brake on autophagy), and sirtuin support. A 2025 study (Kim et al.) demonstrated significant autophagy marker increases at doses above 400mg daily.
