Abstract: Grape seed extract (GSE), derived as a by-product from Vitis vinifera processing, is rich in polyphenolic compounds, particularly proanthocyanidins, which exhibit potent antioxidant, anti-inflammatory, and anti-diabetic properties. GSE contains a complex mix of monomers, oligomers, and polymers of catechin and epicatechin derivatives. This study investigated the clinical efficacy of GSE supplementation in a double-blind, randomized controlled trial involving 48 type 2 diabetic patients with chronic periodontitis. Over eight weeks, participants received either GSE or placebo capsules. Outcomes included oxidative, inflammatory, and glycaemic biomarkers, showing improvements in the GSE group. Advanced extraction and formulation methods, such as phytosome encapsulation and nanoparticle synthesis, were explored to enhance GSE’s bioavailability. Analytical techniques including UV-vis spectrophotometry, FTIR, TEM, and dynamic light scattering were used to characterize GSE formulations. GSE demonstrated significant antioxidant capacity in vitro and in vivo and has promising therapeutic potential in managing metabolic and inflammatory conditions.
