Grape Seed Extract

Grape seed extract is a dietary supplement made from the seeds, skin, and stems of grapes. It is typically produced by drying the seeds and then extracting the beneficial compounds using a solvent, followed by purification and concentration.

Grape seed extract is often added to dietary supplements and some beverages. It is valued for its antioxidant properties, primarily due to its high concentration of proanthocyanidins.

In the US, grape seed extract is generally recognized as safe (GRAS) when used as intended in dietary supplements. Research suggests it may have antioxidant and anti-inflammatory effects, but more high-quality human studies are needed to confirm these benefits. The European Food Safety Authority (EFSA) has not established a specific opinion on grape seed extract as a food additive. Some studies have explored its potential role in cardiovascular health and blood sugar management, but results are mixed and not conclusive.
