Green Tea Extract EGCG (Epigallocatechin gallate) is a concentrated form of green tea, primarily extracted from the leaves of the Camellia sinensis plant. EGCG is the most potent and abundant catechin in green tea and is known for its extensive health benefits due to its strong Antioxidant and anti-inflammatory properties. Green Tea Extract EGCG offers a wide range of health benefits due to its potent antioxidant, anti-inflammatory, and fat-burning properties. The high EGCG content in the extract promotes cardiovascular health, aids in weight loss, protects the skin, and supports cognitive function. Its applications in Dietary Supplements, skincare, and functional beverages make it a versatile ingredient for enhancing overall health and wellness.
Active Substances Contained
1. Epigallocatechin Gallate (EGCG):
The main polyphenolic compound and the most biologically active catechin in green tea, responsible for many of its health benefits.
2. Catechins:
Other catechins present in green tea extract include epicatechin (EC), epicatechin gallate (ECG), and epigallocatechin (EGC), which all contribute to its antioxidant properties.
3. Polyphenols:
Green tea contains various polyphenolic compounds that offer health benefits beyond EGCG, including flavonoids and thearubigins.
4. L-Theanine:
An amino acid found in green tea that promotes relaxation and mental clarity without causing drowsiness.
5. Caffeine:
Green tea extract contains a moderate amount of caffeine, which provides a gentle energy boost and increases metabolism.
6. Vitamins & Minerals:
Small amounts of vitamin C, vitamin B2, vitamin E, and magnesium are present in green tea extract, offering additional health benefits.
Specific Effects
1. Antioxidant Properties:
EGCG is a powerful antioxidant that helps neutralize free radicals, reducing oxidative stress. This protects cells and tissues from damage and can lower the risk of chronic diseases like heart disease, diabetes, and cancer.
2. Weight Management:
EGCG has been shown to increase fat oxidation and enhance metabolic rate, making green tea extract popular in weight management supplements. It helps in promoting fat loss, especially around the abdominal area, when combined with exercise.
3. Cardiovascular Health:
EGCG and other catechins in green tea extract improve heart health by reducing LDL cholesterol levels and improving blood vessel function. Regular consumption can lower the risk of heart disease and stroke by preventing the oxidation of LDL cholesterol and reducing arterial plaque buildup.
4. Cancer Prevention:
EGCG is extensively studied for its potential anti-cancer properties. It helps inhibit cancer cell growth, promotes apoptosis (programmed cell death), and reduces the spread of cancer cells. It is most notably linked to lower risks of breast, prostate, and colon cancers.
5. Cognitive Health and Neuroprotection:
EGCG has neuroprotective effects, potentially slowing cognitive decline and lowering the risk of neurodegenerative diseases like Alzheimer’s and Parkinson’s. It helps by reducing oxidative stress in brain cells and promoting the formation of new neurons.
6. Anti-Inflammatory Effects:
EGCG reduces inflammation by inhibiting pro-inflammatory cytokines and signaling pathways. This can help manage conditions like arthritis, inflammatory bowel disease, and other chronic inflammatory conditions.
7. Skin Health:
Green tea extract is widely used in skincare for its anti-aging properties. EGCG protects skin cells from UV damage, improves skin elasticity, and reduces wrinkles and fine lines by promoting collagen synthesis. It also helps soothe irritated skin and reduce acne due to its anti-inflammatory properties.
8. Blood Sugar Regulation:
EGCG can help improve insulin sensitivity and regulate blood sugar levels, which is beneficial for individuals with type 2 diabetes. It reduces glucose absorption in the intestines and enhances glucose utilization in cells.
9. Mental Focus and Relaxation:
The combination of caffeine and L-theanine in green tea extract improves mental focus, alertness, and cognitive function while promoting relaxation. Unlike coffee, the caffeine in green tea extract does not lead to jitteriness, as L-theanine counteracts these effects.
10. Liver Protection:
Green tea extract supports liver health by reducing fat accumulation in the liver and protecting against non-alcoholic fatty liver disease (NAFLD). It also enhances detoxification processes by promoting the activity of antioxidant enzymes in the liver.
11. Antimicrobial Properties:
EGCG has antimicrobial effects that can help fight bacteria, viruses, and fungi. It is particularly effective against oral bacteria, reducing the risk of cavities and gum disease, and may inhibit the growth of harmful gut bacteria.
12. Blood Pressure Regulation:
Regular consumption of green tea extract may lower blood pressure by improving endothelial function and reducing inflammation in the blood vessels. This effect is linked to the relaxation of blood vessels, contributing to improved circulation.
Applications
1. Dietary Supplements:
Green tea extract is commonly found in capsules and tablets, often marketed for weight loss, heart health, and antioxidant support.
2. Functional Beverages:
Green tea extract is added to energy drinks, smoothies, and teas to provide a natural energy boost and antioxidant benefits.
3. Skincare:
EGCG is used in creams, lotions, and serums to fight signs of aging, improve skin tone, and protect against UV damage.
4. Sports Nutrition:
Due to its fat-burning and energy-enhancing properties, green tea extract is often included in pre-workout supplements and fat burners.
5. Cognitive and Mood Supplements:
The presence of L-theanine and caffeine in green tea extract makes it a popular choice in supplements designed to improve focus, alertness, and relaxation.
6. Blood Sugar and Insulin Regulation:
Green tea extract is used in supplements aimed at improving metabolic health and regulating blood sugar levels in individuals with diabetes or metabolic syndrome.
