Green tea extract is the active ingredient extracted from green tea leaf tablets, mainly including tea polyphenols (catechins), caffeine, aromatic oils, water, minerals, pigments, carbohydrates, proteins, amino acids, vitamins and others. Tea polyphenols have the effects of antioxidant and free radical scavenging, significantly reduce the serum total cholesterol, triglyceride and low-density lipoprotein cholesterol content of hyperlipidemia, and at the same time have the effect of restoring and protecting vascular endothelial function. The hypolipidemic effect of tea polyphenols is also one of the main reasons why tea can make obese people lose weight without rebounding.
Product source and raw material guarantee
Core raw material：The tea leaves are organically grown in high-quality green tea producing areas in China (such as Mount Emei, Mount Wuyi, etc.). The tender leaves of spring tea are selected, and the content of tea polyphenols is 30%-50% higher than dinary tea leaves.
Harvesting standards: Follow the "three no-harvesting" principle (no harvesting on rainy days, no harvesting on frost days, and no harvesting when the buds and leaves are not mature) to ensure the peak value of the active ingredients in the raw materials
Definition and core ingredients
Tea polyphenols are an active mixture extracted from green tea leaves through the process of [low temperature countercurrent extraction/membrane separation purification], contains:
Epigallocatechin gallate (EGCG): The core antioxidant component (accounting for 15%-98%)
Catechin：Key ingredients for regulating lipid metabolism (30%-90% content optional)
L-Theanine：Synergistically enhance neuroprotective effects (20%-30% specification)
Chemical properties：CAS 34271-54-0 | Molecular formula C₇H₁₄N₂O₃ | Appearance：Brown to off-white powder
Scientifically verified efficacies
Antioxidant and anti-aging
ORAC value reaches 30,000 μmol TE/g, and its free radical scavenging ability is 18 times that of vitamin E, delaying skin photoaging (clinical results show that wrinkles are reduced by 22%)
Inhibit lipid peroxidation, protect cardiovascular endothelial function, and reduce the risk of atherosclerosis
Metabolic regulation and weight management
Inhibit lipase activity, reduce dietary fat absorption by 30%, and assist obese people in stable weight loss (rebound rate reduced by 45%)
Activate the AMPK pathway and accelerate fat decomposition (animal experiments show that body fat percentage is reduced by 18%)
Radiation Protection and Detoxification
Adsorb heavy metals (lead, cadmium, etc.) to form complexes and reduce toxicity (in vitro detoxification rate reaches 68%)
Reduces UV damage and acts as a natural sunscreen (40% increase in SPF)
Antibacterial and health support
Inhibit Helicobacter pylori (MIC≤0.5mg/mL) and oral pathogens (92% effective in preventing dental caries)
Improve the side effects of radiotherapy and chemotherapy, and maintain stable white blood cell levels (65% effective in clinical adjuvant therapy)
Application scenarios and usage methods
Dietary supplements development
Soft capsules/Tablets: Encapsulate standardized extracts (a single capsule contains 50-200 mg of tea polyphenols), combined with vitamin C to enhance antioxidant effects.
Sports nutritions: Compounded with caffeine (3:1 ratio), increases fat metabolism rate by 18%.
Functional foods innovation
Beverage additives: Add 0.5-1g of extract per liter, pH tolerance range 3-9 (does not affect flavor).
Natural preservatives: Replace sodium benzoate and extend the shelf life of baked goods by 3 days.
Medicine and cosmetics
Anti-aging essence: 1%-5% concentration inhibits collagen degradation (clinical results show that skin elasticity increases by 18%)
Targeted drug delivery: Nanoliposome encapsulation technology (particle size <100nm) to enhance the permeability of anticancer drugs
Applicable people and contraindications
Target people：
Metabolic syndrome and obese people
People in occupations with high risk of ultraviolet exposure (such as outdoor workers)
Patients undergoing radiotherapy and chemotherapy (need for adjuvant therapy)
Quality assurance system
Test report: HPLC spectrum, heavy metal (Pb≤0.5ppm) and microbial testing are provided for each batch.
Customized service: Support water solubility optimization (β-cyclodextrin encapsulation), flavor modification (removal of bitterness)
Stability test: 40℃ accelerated test for 6 months, active ingredient retention rate ＞95%
FAQ Section
Q: What is the difference between green tea extract and green tea powder?
A: The extract is concentrated through a standardized process, and the concentration of tea polyphenols is 20-50 times that of the original powder, and the microbial index is strictly controlled at <1000CFU/g
Q: How to solve the bioavailability problem of EGCG?
A: Using phospholipid complex embedding technology, the absorption rate is increased by 3 times (verified by clinical trials).
Q: What is the minimum order quantity and sample policy?
A: Support 1kg sample trial, with COA and formula development guide
