Scientific findings suggest that EGCG, contained in green tea, may play a pivotal role in safeguarding cardiovascular well-being by reducing blood pressure, cholesterol levels, and the accumulation of arterial plaque—key factors linked to heart disease. Moreover, EGCG is believed to enhance both metabolic and vascular functions associated with insulin.
The acclaim surrounding EGCG is primarily rooted in its potent antioxidant properties and its potential to mitigate stress and inflammation. Research has highlighted that epigallocatechin exhibits antioxidative, anti-inflammatory, and antiatherogenic effects, employing pathways mediated by growth factors, the mitogen-activated protein kinase-dependent pathway, and the ubiquitin/proteasome degradation pathway.
The generation of free radicals, highly reactive particles capable of harming human cells, leads to oxidative stress when produced excessively. EGCG has demonstrated the capacity to scavenge these free radicals, showcasing additional positive effects in protecting cells and tissues throughout the body.
While EGCG stands out as the most extensively researched and potent catechin, other varieties such as epicatechin, epigallocatechin, and epicatechin 3-gallate may offer similar benefits. Notably, many of these catechins are readily available in various food sources.
