Name and Basic Overview

NOW Foods Grape Seed Standardized Extract is a dietary supplement designed to provide free radical protection and support vascular health. It is available in 100 mg capsules and is suitable for vegetarians and vegans.

The extract is derived from grape seeds, which are known for their high polyphenol content, particularly Oligomeric Proanthocyanidins (OPCs). People commonly use grape seed extract for its antioxidant properties, aiming to support immune function and overall health.

Historical Background / Traditional Use

Grape seeds have been used historically in various cultures for their medicinal properties, often in the form of grape seed oil or extracts. In traditional European medicine, grape seed extracts were used for their purported benefits in treating conditions related to poor circulation and inflammation.

Modern usage focuses on its antioxidant capabilities, which are believed to help combat oxidative stress and support cardiovascular health.

Composition and Active Components

The primary active components in NOW Foods Grape Seed Extract are polyphenols, with a minimum of 90% concentration, including OPCs. OPCs are known for their potent antioxidant activity, which helps neutralize free radicals and reduce oxidative stress in the body.

The supplement also includes Vitamin C, an essential nutrient that enhances the antioxidant effect and supports immune function. Calcium is present in a small amount, contributing to bone health and metabolic functions.

Research and Evidence Base

Several studies have investigated the health benefits of grape seed extract, particularly its role in cardiovascular health. Research suggests that OPCs may improve blood flow and reduce blood pressure, contributing to vascular health.

A meta-analysis of clinical trials indicates that grape seed extract can significantly reduce systolic and diastolic blood pressure, especially in individuals with metabolic syndrome. Preliminary studies also suggest potential benefits for brain health, kidney function, and bone health, although more research is needed to confirm these effects.

The evidence supporting the antioxidant and immune-boosting properties of grape seed extract is robust, but further studies are required to fully understand its mechanisms and long-term benefits.
