Oxidative stress, a major contributor to aging and various chronic diseases, is mitigated by OPCs' ability to scavenge free radicals, preventing cellular damage and promoting overall well-being. The mechanism of action involves OPCs' ability to donate electrons to free radicals, stabilizing them and preventing them from causing further damage to cellular components like lipids, proteins, and DNA.
Beyond OPCs, GSE contains other beneficial compounds, including procyanidins, catechins, and other polyphenols. These compounds contribute to the extract's synergistic effects, meaning their combined action is greater than the sum of their individual effects. The precise composition of GSE can vary depending on the grape variety, growing conditions, and extraction methods. However, the consistent presence of OPCs is the key factor contributing to its recognized health benefits. Research continues to explore the full spectrum of bioactive compounds in GSE and their individual contributions to its overall efficacy.
