Antioxidant: Tea polyphenols possess strong antioxidant capabilities, which can neutralize free radicals, reduce oxidative stress, and protect cells from damage.
Anti-inflammatory: Tea polyphenols have anti-inflammatory properties that can help reduce inflammation and alleviate symptoms of inflammation-related diseases.
Antibacterial and Antiviral: Tea polyphenols can inhibit the growth of various bacteria and viruses, aiding in the prevention of infections.
Cardiovascular Health: Tea polyphenols help lower blood pressure, reduce low-density lipoprotein (LDL) cholesterol, improve cardiovascular health, and reduce the risk of heart disease.
Anti-cancer: Research suggests that tea polyphenols may have anti-cancer properties, capable of inhibiting the growth and spread of cancer cells.
Weight Loss and Metabolic Regulation: Tea polyphenols can aid in weight loss by increasing metabolism and promoting fat oxidation.
Neuroprotection: Tea polyphenols may have neuroprotective effects, helping to prevent neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease.
Tea polyphenols are collectively referred to as polyphenolic compounds and mainly include the following categories:
Catechins: These primarily include epigallocatechin gallate (EGCG), epicatechin (EC), epigallocatechin (EGC), and epicatechin gallate (ECG).
Flavonoids: This category includes compounds such as quercetin and kaempferol.
Anthocyanins: These are mainly found in certain types of tea, such as black tea.
Phenolic Acids: Examples include caffeic acid and gallic acid.
