Grape seed

Grape seeds are the small seeds found inside grapes. After grapes are pressed to make juice or wine, the seeds are typically a byproduct. They can be processed to extract oil or used in powdered form.

Grape seed extract is often used in dietary supplements for its antioxidant properties. Grape seed oil is used as a cooking oil for its high smoke point and neutral flavour. In some foods, it may be used as a source of beneficial compounds.

Grape seed extract is not typically considered a food additive in the UK, but rather a supplement ingredient. Regulatory bodies like the European Food Safety Authority (EFSA) have evaluated compounds found in grape seed extract. While some studies suggest potential health benefits, such as antioxidant effects, the evidence for significant health impacts at typical dietary intakes is still under investigation and mixed. Further research is ongoing to fully understand its effects.
