What is Grape Seed Extract:
Grapes have been used in Europe for thousands of years. They're used to treat everything from arthritis to cancer, and their leaves and sap have been used for centuries as folk medicines.

Red wine grapes are the most commonly used source of grape seed extract, but there are other types of grapes that can be ground up and used in an extract. These include white and yellow varieties, as well as hybrids between them.

Grape seed oil (GPSO) is a by-product from winemaking that has awakened great interest and relevance, both in the industry and research areas. It's basically a fat extracted from the seeds of red wine grapes.

In addition to its use in cosmetics, GPSO can help eliminate waste generated by industry by using it as an adjuvant in different treatment lines. Because it contains different bioactive compounds—antioxidants, antiinflammatories and anticancer agents—it has potential health benefits beyond its cosmetic applications.

Grape Seeds Extract could be a big help for people who have high blood pressure. Several studies have researched the effects of GSE on high blood pressure. A review of 16 studies in 810 people with high blood pressure or an elevated risk of it found that taking 100–2,000 mg of Grape Seed Extract daily significantly reduced systolic and diastolic blood pressure (the top and bottom number) by an average of 6.08 mmHg and 2.8 mmHg, respectively. Those under the age of 50 with obesity or a metabolic disorder showed the greatest improvements.

The most promising results came from lower doses of 100–800 mg daily for 8–16 weeks, rather than a single dose (8Trusted Source).

Could reduce oxidative damage

An elevated blood level of LDL (bad) cholesterol is a known risk factor for heart disease. The oxidation of LDL cholesterol significantly increases this risk and plays a central role in atherosclerosis, or the buildup of fatty plaque in your arteries (8Trusted Source). GSE supplements have been found to reduce LDL oxidation triggered by high fat diets in several animal studies
