The health benefits of grape seed extract are commonly discussed on blogs and forums around the web and this is quickly becoming yet another superstar-superfood story.
But what precisely are these vaunted benefits and does it really deliver on them?
Antioxidant Properties
Grape seed extract comes from the seeds of red wine grapes which are ground up and used for a variety of health purposes.
The main benefits of grape seed extract revolve around its antioxidant properties. Those who know their superfoods may well be aware of the impressive benefits of red grapes – which contain the highly potent antioxidant resveratrol. Resveratrol is in fact highly popular among the life-extension crowd who believe it has the potential to protect the cells against ageing more effectively than other antioxidants. What’s more, it also improves mitochondrial function, resulting in enhanced energy levels, better sleep and possible cognitive benefits.
Grape seed extract likewise appears to be very effective in combating free radicals thanks to its flavonoid phytonutrients including not only resveratrol itself but also oligomeric proanthocyanidin complexes (OPCs). Grape seed extract in fact contains 95% OPCs, which is more than any other antioxidant extract. OPCs aid the body in the production of glutathione, which you may also have heard of as being the ‘master antioxidant’ that helps to regulate the body’s production of all other antioxidants. This also increases intracellular vitamin C and strengthens the capillaries.
Overall, grape seed oil appears to be a very effective source of antioxidants (1), making it a good candidate for general health supplementation.
Additional Benefits, Uses and Risks
In particular, the raised levels of antioxidants in the blood make grape seed extract very popular for cardiovascular conditions and it is often recommended for poor circulation and high cholesterol.
It also has anti-inflammatory properties which makes it a good choice for reducing swelling after injury. These benefits are partly the result of grape seed extract’s action on the TH2 immune system which can help to balance the thyroid hormones and control cytokine levels. That said, it may have negative effects on those with existing thyroid conditions, so it is recommended that you consult with your doctor if you have TH2 dominance.
On top of this, grape seed oil is also high in vitamin E, making it popular for improving the skin and complexion. It is often recommended for protecting the skin against UV damage and for treating rashes and blemishes – though there isn’t a lot of evidence to support this use.
Overall, grape seed extract is an excellent health supplement for boosting the immune system and protecting the cells. There is really just one main thing that it has going against it: the cost!
