What is Grape Seed Extract?
Grape seed extract is a substance derived from the seeds of grapes. Scientifically belonging to the Vitis genus, most grape seed extract is made from Vitis vinifera, as are many types of wine, but there are a handful of other species from which this extract can be made. Grape seed extract is produced by grinding up the seeds found at the center of grapes and then using a steam distillation or cold-pressing method to extract the pure compounds of the seeds. Some of the most important compounds found in grape seed extract are tannins, oligomeric procyanidins, catechins and epicatechins, as well as vitamin E, and linoleic acid.

Grape Seed Extract OPCs
In grape seed extract one type of polyphenol called oligomeric proanthocyanidin (OPC) is present at higher concentrations than all the others. OPC is a powerful antioxidant responsible for most of the beneficial therapeutic effects of grape seed extract. Proanthocyanidins are also found in other common foods and spices like fruits and especially berries, nuts, cinnamon, cocoa, and tea (EGCG is also a proanthocyanidin). Like these other foods, proanthocyanidins are found in grape skins and juice, but grape seed extract contains a much higher concentration. In fact, 70-90% of grape seed extract may be proanythocyanidins. The rest of grape seed extract contains procyanidin, different forms of catechins, and other bioactives in smaller amounts.
Then what can we benefit from the powerful OPCs? See the picture and know more about the health benefits we could get from the wonderful grape seed fruit.
Side effects of Grape Seed Extract
Common side effects include: Headache, sore throat, dizziness, itchy scalp, stomach ache, nausea.
It is important to talk to your doctor before taking grape seed extract as it can affect the way that certain medications are broken down in the liver.
Grape seed extract might also act as an anticoagulant, or blood-thinner. It could increase the risk of bleeding if taken with other blood-thinners such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin.
The NCCIH describes grape seed extract as "generally well tolerated when taken in moderate amounts."
