Grape Seed Extract - 95%

Enovita® Standardized grape seed extract with 95% proanthocyanidins for support of cardiovascular health

Chronic health issues that lead to less than optimal function of the cardiovascular system are increasingly common among many American adults. It is little wonder that they are seeking interventions to help maintain and enhance their heart health. In addition to diet and exercise, supplementation can be an effective way to provide the cardiovascular system with additional support.

Princeton Vitamins is pleased to announced a new formula with clinically validated grape seed extract designed to help maintain and enhance the function of these vital systems.*

Princeton Vitamin’s Grape Seed Extract 95% (Vitis vinefera) is made with Enovita®**, a proprietary proanthocyanidin-rich extract of grape seeds from white wine production. Grape seeds are rich in numerous important antioxidant compounds, including phenolic acids, anthocyanins, flavonoids and is an exceptionally good source of oligomeric proanthocyanins (OPCs). Scientific studies on grape seed extract have shown that the antioxidant power of proanthocyanidins is 20 times higher than Vitamin D and as much as 50 times greater than Vitamin C.[1]

Princeton Vitamin’s formula

The food grade Enovita ingredient is extracted with water and is standardized to provide ˃ 95% of proanthocyanidins, ˃ 5%-˃ 15% catechin and epicatechin. The formula itself is based on well-substantiated evidence for grape seed extract’s support of cardiovascular function. [2] [3]

Scientific studies

Grape seed extract has seen particularly strong evidence for its support of healthy blood pressure. For example, a 2016 meta-analysis demonstrated that grape seed extract enhances healthy blood pressure.[4] Enovita grape seed extract specifically has been shown to support maintenance of normal blood flow when associated with diet and lifestyle modification in healthy people with borderline pressure.[5] In this 2013 study, two doses were evaluated, 150 and 300 mg/day, using blood pressure and heart rate as primary endpoints, over four months of treatment. The researchers concluded that both dosage groups saw improvement, but 93% of those with the higher 300 mg dose saw a normalization of blood pressure. The data suggests that grape seed extract, in the profile associated with Enovita®, are worth considering to complements dietary and lifestyle changes associated with attainment of healthy blood pressure status. The researchers also note that the effect on blood pressure adds to the beneficial effects of grape seed extract on cardiovascular health.*
