Green Coffee Beans

They are not usually consumed as whole beans but processed into extracts, capsules, or powders for supplements — and sometimes brewed as a mild green coffee drink.

What They Are

• Botanical name: Coffea spp.
• Form: Raw, unroasted coffee beans.
• Taste: Earthy, grassy, and less bitter than roasted coffee.
• Key Difference: Roasting destroys much of the chlorogenic acid (antioxidant), so green beans are often considered more “therapeutic.”

Key Active Compounds

• Chlorogenic acids (CGA) → antioxidant, supports metabolism, and blood sugar regulation.
• Caffeine → mild stimulant (lower than roasted coffee).
• Polyphenols → anti-inflammatory, heart-protective.

Health Benefits of Green Coffee Beans

1. Weight Management

• Chlorogenic acid may reduce carbohydrate absorption in the gut.
• May boost fat metabolism (though studies are mixed).

2. Blood Sugar Regulation

• Helps lower post-meal blood sugar spikes.
• May improve insulin sensitivity.

3. Heart & Circulation Health

• Antioxidants protect against oxidative stress.
• May help lower blood pressure.

4. Energy & Mental Alertness

• Contains caffeine but less than roasted coffee, so provides a gentle energy lift.

5. Liver Health

• Some studies suggest green coffee may help reduce fat accumulation in the liver.

Traditional & Modern Uses

• Dietary supplement: Widely marketed for weight loss support.
• Functional drinks: Brewed like herbal tea (green coffee infusion).
• Ayurveda & herbal medicine: Not traditional, but sometimes incorporated as a modern metabolic aid.

Side Effects & Precautions

• Caffeine-related issues: May cause jitteriness, insomnia, and rapid heartbeat in sensitive individuals.
• Digestive upset: High doses may cause stomach discomfort.
• Drug interactions: Can interact with medications for blood pressure, diabetes, or stimulants.
• Pregnancy/breastfeeding: Not recommended in supplement form without medical advice.

How to Use Green Coffee Beans

1. As a drink:

• Soak 20–25 g of green beans overnight, boil in 300 ml water, simmer 10–15 min, strain & drink.
• Flavor is mild, earthy, and slightly sour.

2. As a supplement:

• Commonly sold as capsules or powders standardized to chlorogenic acid content.

3. As an extract:

• Often used in weight management formulas.

Tip: For general health, green coffee is usually consumed in the morning or early afternoon to avoid sleep disruption.
