Green Tea: How It Boosts Metabolism and Promotes Healthy Aging

RRI.CO.ID, Jakarta - Green tea (Camellia sinensis) is one of the most researched beverages worldwide due to its high concentration of catechins, particularly epigallocatechin gallate (EGCG). Beyond being a popular drink, green tea has been investigated for its potential role in metabolism, cardiovascular health, and healthy aging.

A review published in the journal Molecular Nutrition & Food Research reported that green tea catechins possess biological activities related to oxidative stress regulation and metabolic processes. EGCG is considered one of the most important compounds contributing to green tea’s health-related properties.

One of the most evaluated benefits of green tea is its relationship with metabolism. Research has investigated whether catechins combined with caffeine may influence energy expenditure and fat oxidation, although effects vary among individuals.

Green tea has also attracted attention in healthy aging research. Polyphenols in green tea are recognized for their ability to protect cells from oxidative stress and support cellular defense mechanisms.

The cosmetic industry widely incorporates green tea extract into skincare products. Catechins and polyphenols are explored for applications related to skin protection, soothing formulations, and products targeting environmental stressors.

Although green tea is generally safe as a beverage, excessive intake of concentrated extracts may cause side effects due to caffeine and high catechin levels. Balanced consumption remains important.
