Rating (out of 5): 3

Epigallocatechin, primarily in the form of epigallocatechin gallate (EGCG), is a major catechin found in green tea. Scientific research has explored EGCG’s effects on cardiovascular health, including its potential role in supporting arterial function. Studies suggest that EGCG exhibits antioxidant and anti-inflammatory properties, which can help reduce oxidative stress and inflammation in blood vessels. Some clinical trials and meta-analyses indicate that regular consumption of green tea or EGCG supplements may modestly lower blood pressure and improve endothelial function, both of which are important for arterial health.

EGCG is thought to enhance the production of nitric oxide, a molecule that helps relax and dilate blood vessels, thereby improving blood flow and reducing arterial stiffness. Additionally, animal and in vitro studies have shown that EGCG may inhibit processes involved in the development of atherosclerosis, such as the oxidation of low-density lipoprotein (LDL) cholesterol and proliferation of vascular smooth muscle cells.

However, while the evidence is promising, most of the data come from small to moderate-sized human studies, and the observed effects are generally modest. Large-scale, long-term clinical trials are still lacking to confirm these benefits. Thus, the use of EGCG to support arterial health is scientifically plausible and supported by a moderate body of evidence, but it should not be considered a standalone treatment for arterial disease.
