Green Tea Extract Powder

Green tea extract is a concentrated form of the beneficial compounds found in green tea leaves (Camellia sinensis). Instead of drinking multiple cups of tea, the extract provides a higher, standardized dose of key antioxidants — especially catechins like EGCG (epigallocatechin gallate) — which are linked to benefits for metabolism, heart health, brain function, and skin health.

What It Is

• Botanical name: Camellia sinensis (leaves).
• Form: Capsules, tablets, powders, liquid extracts.
• Standardization: Typically 40–50% catechins, with a focus on EGCG.
• Difference from brewed tea: Much higher concentration of antioxidants and more consistent dosage.

Key Active Compounds

• Catechins (EGCG, ECG, EGC, EC) → powerful antioxidants, support fat burning & protect cells.
• Caffeine → mild stimulant, enhances metabolism and focus.
• L-theanine → calming amino acid, balances caffeine effects.
• Polyphenols → anti-inflammatory, anti-aging, protective for heart & brain.

Health Benefits of Green Tea Extract

1. Weight Management & Metabolism

• EGCG + caffeine increases fat oxidation.
• Often included in fat-burning supplements.

2. Heart & Circulatory Health

• May reduce LDL (“bad”) cholesterol.
• Improves blood vessel function and circulation.

3. Brain Health & Focus

• EGCG crosses the blood-brain barrier → protects neurons.
• Caffeine + L-theanine improves focus without jitters.

4. Blood Sugar Regulation

• Supports insulin sensitivity.
• Helps reduce blood sugar spikes after meals.

5. Skin & Anti-aging

• Antioxidants protect skin from UV and oxidative damage.
• Often used in cosmetic creams and serums.

6. Liver Support & Detox

• Helps reduce fat accumulation in the liver.
• Widely marketed as a detox supplement.

Traditional & Modern Uses

• Traditional: In China and Japan, green tea has been consumed for thousands of years as a health tonic.
• Modern: Extract is used in supplements for weight loss, cardiovascular support, anti-aging, and skin care.

Side Effects & Precautions

• Caffeine-related issues: jitteriness, insomnia, anxiety (though less than coffee).
• Liver toxicity (rare): Very high doses of EGCG can strain the liver — best taken with food.
• Drug interactions: May interfere with blood thinners (warfarin), stimulant drugs, or diabetes medications.
• Pregnancy/breastfeeding: Should be used with caution due to caffeine.

How to Use Green Tea Extract

• Capsules/tablets: Standard dose = 250–500 mg extract daily (often 45–60% EGCG).
• Powder: ½–1 tsp in smoothies, juices, or warm water (avoid boiling water, which may degrade antioxidants).
• Skincare: Found in creams, serums, and sunscreens for anti-aging effects.

Tip: Take the extract with meals to reduce the risk of stomach irritation and improve absorption.
