What Is Grape Seed Extract?

Grape seed extract is a dietary supplement made by removing, drying, and pulverizing the bitter-tasting seeds of grapes.

Grape seeds are rich in antioxidants, including phenolic acids, anthocyanins, flavonoids, and oligomeric proanthocyanidin complexes (OPCs).

In fact, Grape seed extract is one of the best-known sources of proanthocyanidins.

Due to its high antioxidant content, Grape seed extract can help prevent disease and protect against oxidative stress, tissue damage, and inflammation.

Grape seed extract is available as a dietary supplement in a liquid form, tablets, or capsules. Supplements commonly contain between 50 and 100 milligrams (mg) of the extract.

What is Grape Seed Extract Good for?

  • Enhanced wound healing

Grape seed extract has been proven to help wounds heal more rapidly and with less scarring. The extract increases levels of tenascin, a protein that helps build the connective tissue that appears as pink skin when a wound is healing.[5] The powerful antioxidant also enhances the formation of epidermal tissue so it is stronger and healthier after healing, and improves function of connective tissue.

  • Reduced inflammation

Swelling caused by surgery or an injury can be reduced more quickly by taking grape seed extract. Its OPCs help to minimize symptoms of chronic venous insufficiency, blood pools in the legs that cause pain, swelling and visible veins.

  • Improved cardiovascular health

The antioxidants found in grape seed extract can help protect blood vessels from becoming damaged, which can lead to higher blood pressure and improve overall cardiac function.

  • Improved cognition

Grape seed extract has been associated with improvements in reaction time and psychomotor skills among older adults, helping to slow and reduce the cognitive effects of aging.

Dosage: How Much Grape Seed Extract Should I Take?

Due to the lack of supporting research, it’s too soon to recommend a specific dose of GSE for any health purpose. Different doses of the extract have been used in research.

For example, doses ranging from 100 milligrams to 400 milligrams daily for six to 12 weeks have been researched. However, your recommended dose may vary based on gender, age, weight, and medical history.
