Description

L-Theanine EGCG Tea Polyphenols Green Tea Extract

Brief introduction

Green tea extract is an active ingredient extracted from green tea leaves, mainly including tea polyphenols (catechins), caffeine, aromatic oils, water, minerals, pigments, carbohydrates, proteins, amino acids, vitamins, etc.

Tea polyphenols have antioxidant and free radical scavenging effects, significantly reducing serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels in hyperlipidemia.

At the same time, they have the function of restoring and protecting vascular endothelial function. The lipid-lowering effect of tea polyphenols is also one of the main reasons why tea can help obese people lose weight without rebounding.

Function
  • Hypolipidemic effect :

Green Tea Extract can significantly reduce the levels of serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol in hyperlipidemia, while also having the effect of restoring and protecting vascular endothelial function. The lipid-lowering effect of tea polyphenols is also one of the main reasons why tea can help obese people lose weight without rebounding.

  • Antioxidant effect :

Tea Polyphenols can block the process of lipid peroxidation, improve the activity of enzymes in the human body, and thus have anti mutation and anti cancer effects.

  • Anti tumor effect :

Green Tea Extract can inhibit the synthesis of DNA in tumor cells, induce mutated DNA breakage, and thus inhibit the synthesis rate of tumor cells, further inhibiting the growth and proliferation of tumors.

  • Bactericidal and Detoxifying Effect :

       Green Tea Extract can kill botulinum toxin and spores, and inhibit the activity of bacterial exotoxins. It has antibacterial effects on various pathogenic bacteria that cause diarrhea, respiratory and skin infections. Tea polyphenols have a significant inhibitory effect on Staphylococcus aureus and Streptococcus mutans, which can cause purulent infections, burns, and injuries.

  • Anti alcoholic and liver protective effects :

Alcoholic liver injury is mainly caused by free radical damage caused by ethanol. Tea polyphenols, as free radical scavengers, have the effect of inhibiting alcoholic liver injury.

  • Detoxification effect :

Severe environmental pollution has a significant toxic effect on human health. Tea polyphenols have a strong adsorption effect on heavy metals and can form complexes with heavy metals to produce precipitation, which is conducive to reducing the toxic effect of heavy metals on human health.In addition, tea polyphenols also have the effects of improving liver function and diuresis, thus having a good antidote effect on alkaloid poisoning.

  • Improving the body’s immunity :

Tea polyphenols increase the total amount of immunoglobulin in the human body and maintain it at a high level, stimulate changes in antibody activity, thereby improving the overall immune capacity of the human body and promoting the body’s self-regulation function.
