Grape Seed Extract (25 mg): Contains high levels of polyphenols and proanthocyanidins, which are powerful antioxidants that protect against cell damage and improve blood circulation
It acts directly on neighboring -cells to inhibit the secretion of glucagon and can also indirectly influence -cells by inhibiting the secretion of other hormones.243 In the local islet environment, a high concentration of somatostatin creates an inhibitory milieu, further reducing the activity of -cells and the secretion of glucagon.244 Additionally, somatostatin can inhibit gastrointestinal activity, reducing the secretion of pancreatic enzymes and gastric acid, thereby indirectly decreasing the demand for glucagon.245,246 Hence, GLP-1 activates -cells and promotes somatostatin secretion, forming a multi-layered inhibitory mechanism that effectively reduces glucagon secretion

Practical Considerations Favoring Oral Delivery: Beyond bioavailability questions, oral administration offers significant lifestyle advantages that make peptide therapy accessible to a broader population: No Injection Requirement: Many individuals interested in tissue support supplementation are deterred by injection protocols
