A 2016 meta-analysis concluded that grape seed extract, in a dose of under 800 milligrams per day over at least 8 weeks, might help to reduce systolic and diastolic blood pressure. [7] People with metabolic syndrome had a more significant outcome (average of a 8½ mmHg decrease in systolic blood pressure) than in healthy subjects. [7]
The Porter Assay is a chemical test to help determine the potency of procyanidin containing compounds, such as grape seed extract. It is an acid hydrolysis, which splits larger chain units (dimers and trimers) into single unit monomers and oxidizes them.
