How it works
Grape Seed Extract is derived from grape seeds which have a strong concentration of vitamin E, flavanoids, linoleic acid, and phenolic compounds known as Oligomeric proanthocyanidins (OPCs). The supplement has a number of different mechanisms of action to work. The flavanoids and polyphenols are considered to be such compounds which are the most active and cause effects. They both primarily work as antioxidants. They are able to eat up free radicals and remove many different types of chemicals and compounds from the body.
The most important component of Grape seed extract is Resveratrol, also known as 3,5,4′-trihydroxy-trans-stilbene. Resveratrol has great effects as an anti-cancer, anti-inflammatory, and antioxidant, as well as on stabilizing blood sugar levels and improving cardiovascular function.
Procyanidins from Grape Seed, in studies, have been shown to exert anti-oxidative effects in vitro in PC12 neurons, and can fully protect H2O2 induced cytotoxicity at a certain concentration without negatively affecting cell viability. Grape seed extract is also shown to protect cells from cytotoxicity induced by beta-amyloid pigmentation. In reference to a different study, feeding a strain of animals, especially mice with Alzheimer’s-like cognitive deficits, Grape Seed Extract (GSE) daily at a certain concentration for 5 months found notable cognitive improvement.
Though Grape Seed Extract is generally considered safe, it has relatively a few side effects. The most common ones may include headache, itchy scalp, dizziness, sore throat, stomach ache and nausea. However, anyone with an allergy to grapes should avoid using this extract in any form.
You are recommended to take 100 mg to 300 mg of Grape Seed Extract daily as a standard dosage. As with many supplements, it is usually recommended to start with a lower dosage and then increase when tolerable. It is not recommended to take more than 300 mg unless your doctor advises you to do so.
