About this ingredient
Ingredients
Grape Seed Extract is a botanical extract made from the seeds of grapes, particularly Vitis vinifera. It naturally contains proanthocyanidins, along with other polyphenolic compounds. The concentration and composition can vary depending on the grape variety, extraction method, and standardization of the product.
Supplement formulations may provide grape seed extract as a standardized powder, capsule, tablet, or blended botanical ingredient. The exact extract strength, proanthocyanidin content, serving size, and additional ingredients depend on the manufacturer.
Grape Seed Extract is derived from the seeds of grapes and is a concentrated source of plant compounds known as proanthocyanidins. These compounds belong to the broader family of polyphenols and are an important reason grape seed extract is used in botanical nutritional products.
Grape seed extract is commonly included in supplements formulated for antioxidant and general wellness support. Research has also examined its potential effects on cardiovascular-related markers such as blood pressure and blood lipids, although findings vary between studies and products.
The composition of grape seed extracts can differ considerably. Factors such as grape variety, extraction process, and standardization can influence the amount of proanthocyanidins and other compounds present. Consumers should therefore check the product label for the extract amount and standardization when provided.
Grape seed extract is generally well tolerated when taken orally, but people taking medicines should consult a healthcare professional before use because botanical supplements can interact with medications. There is also limited information about its safety during pregnancy and breastfeeding.
