Let's have a look at what grape seed extract contains and its potential benefits of grape seed extract.

Grape seed extract is one of the richest sources of proanthocyanidins, as is pine bark extract.

Proanthocyanidin is one of the classes of flavanoids, an antioxidant found from plant sources which protects them from free radicals and stress.

Proanthocyanidin are made up of 2 types of monomers called catechins and epicatechins, and two or more of these together are called oligomeric proanthocyanidins or OPCs.

In humans, they are a potent antioxidant, more so than the previously known vitamins such as vitamin A, C and E (1)

Grape seeds also contain resveratrol, which is found in grape skin as well, but especially in seeded red grapes than with seedless ones (2).

In a study or grapes in 2006, it was found that certain species of red grapes contained "high extractable amounts of resveratrol in berry skins [>100 μg g-1 of skin fresh weight (FW)] and seeds (>20 μg g-1 of seed FW)" (2)

So what are the potential health benefits of red wine or grape seed extract supplement?

Here's a quote from a BBC report:

"Grape seeds contain a number of antioxidants, including resveratrol, which is known to have anti-cancer properties, as well as positive effect on the heart.

Previous research has shown grapeseed extract has an effect on skin, breast, bowel, lung, stomach and prostate cancer cells in the laboratory." (3)

Grape seed extract has been studied in both in vitro and human studies and has shown:

1. Protection from oxidative stress from free radicals.

2. Destruction of cancer cells

3. Enhancement of growth and viability of normal cells (4)

4. Heart health

In a review article on the effect of grape seed proanthocyanidin or grape seed antioxidant on heart health, it was found that that grape extract in heart patients reduced the size of heart attacks, improved the functioning of the heart afterwards as well. (5)

Resveratrol studies in vitro, animal and in vivo studies have revealed potential benefits for:

1. Longevity

2. Reduced gene and biochemical changes associated with obesity, including changes seen in heart disease and diabetes

3. Anti cancer and anti tumour properties

4. Improved physique

So as you can see, there are a host of potential health benefits of potent grape seed antioxidants and red wine extract for healthy aging and anti aging.

Antioxidants from grape seed and grape skin, including resveratrol has become one of the most researched breakthroughs discovered in recent years.

They have potent antioxidant activities to reduce free radicals and oxidative stress.
