Product Description
Our Catechin powder is a high-purity natural polyphenol extract, available in 98% and 99% grades. Catechin (CAS 7295-85-4) is the core active ingredient of green tea, famous for its powerful antioxidant, anti-inflammatory and metabolic regulation effects, widely used in anti-aging supplements, weight management products, functional foods, and skincare formulations. As a leading bulk Catechin supplier, we offer premium-grade Catechin for global markets.
Catechin is a natural flavan-3-ol polyphenol compound abundant in green tea and various fruits. It includes multiple active monomers such as epicatechin, epigallocatechin, and epigallocatechin gallate, forming a high-efficiency antioxidant system. Compared with ordinary antioxidants, Catechin features stronger free radical scavenging ability, higher safety, and better human absorption, making it one of the most popular natural functional ingredients in the global health industry.
Manufactured by Shaanxi BAISFU Bio-Engineering Co., Ltd., our premium Catechin powder is produced through two advanced, fully traceable production routes to meet the diverse needs of global customers. For natural product-focused clients, we offer 100% plant-derived Catechin, extracted and purified from high-quality green tea leaves using low-temperature water extraction and membrane separation technology, completely retaining natural active ingredients without residual solvents. For high-purity pharmaceutical and cosmetic clients, we provide semi-synthetic Catechin with higher purity, more stable properties, and excellent cost performance without compromising safety and efficacy.
Every batch of our Catechin powder undergoes strict, multi-stage quality control, including HPLC and UV-Vis spectroscopy testing, to ensure all indicators meet international standards. Our Catechin complies with global food safety regulations including FDA GRAS, EU food additive certification and China GB standards, safe and reliable for long-term addition in food, health products and cosmetics.
As a professional bulk supplier, we maintain sufficient stock and complete regulatory documents for all Catechin products. Whether you need raw materials for antioxidant supplements, body management formulas, skin care products or functional beverages, our Catechin powder is your ideal choice for safe, effective, and cost-efficient production.
Functions & Benefits
Superior Antioxidant Activity (Core Benefit)
Catechin boasts extremely strong free radical scavenging capacity, far exceeding vitamin C and vitamin E. It can effectively neutralize excess free radicals in the human body, inhibit lipid peroxidation, reduce oxidative damage to cells and DNA, delay body aging, and enhance the body’s antioxidant defense system. Long-term supplementation helps resist external environmental damage and maintain youthful physical state.
Anti-Inflammatory & Immune Regulation
Catechin effectively inhibits the release of pro-inflammatory factors and blocks inflammatory response pathways, relieving chronic low-grade inflammation in the body. It can regulate immune cell activity, enhance body immune defense capability, reduce the risk of inflammatory lesions, and help maintain stable immune function.
Metabolism & Weight Management Support
As a classic metabolic regulating ingredient, Catechin can promote fat metabolism, inhibit fat accumulation, accelerate calorie consumption, and reduce body fat rate. It also helps regulate blood lipid levels, improve lipid metabolism disorders, and assist in healthy body shaping and weight management, which is widely used in fitness and body care supplements.
Cardiovascular Protection
Catechin helps protect vascular endothelial cells, improve blood vessel elasticity, inhibit cholesterol oxidation, and reduce the deposition of vascular lipids. It can assist in maintaining healthy blood lipids and blood pressure levels, effectively preventing cardiovascular aging and protecting long-term cardiovascular health.
Antibacterial & Deodorizing Properties
Catechin has broad-spectrum antibacterial activity, which can inhibit the growth and reproduction of harmful bacteria, reduce bacterial-induced odor and skin problems. It is mild and non-irritating, widely used in daily chemical and oral care products to achieve antibacterial, fresh and skin-protective effects.
Skin Protection & Anti-Aging Effects
In skincare formulations, Catechin resists UV radiation and environmental oxidative damage to the skin, reduces free radical-induced skin aging, fades fine lines and dullness, and improves skin radiance. Its anti-inflammatory and soothing effects can relieve skin redness and sensitivity, repair skin barrier, and create a delicate and youthful skin state.
