Grape Seed Extract
Grapes — along with their leaves and sap — have been traditional treatments in Europe for thousands of years. Grape seed extract is derived from the ground-up seeds of red wine grapes. Although fairly new to the U.S., grape seed extract is now used to treat a number of diseases.

Why do people take grape seed extract?

There’s strong evidence that grape seed extract is beneficial for a number of cardiovascular conditions. Grape seed extract may help with a type of poor circulation (chronic venous insufficiency) and high cholesterol. Grape seed extract also reduces swelling caused by injury and helps with eye disease related to diabetes.

Many people are interested in grape seed extract because it contains antioxidants. These are substances that protect cells from damage and may help prevent many diseases. However, it’s still too early to say whether the antioxidant properties of grape seed extract really benefit people. Researchers are studying grape seed extract to see if it might lower the risks of some cancers. For now, the evidence is not clear.

Grape seed extract has been studied for use in many other conditions — ranging from PMS to skin damage to wound healing — but the results have been inconclusive.

How much grape seed extract should you take?

There is no firmly established dose of grape seed extract. Doses of between 100-300 milligrams/day have been used in studies and are prescribed in some European countries. No one knows what the highest safe dose is.

Can you get grape seed extract naturally from foods?

Grape seed extract comes from grapes. There are no other food sources.

What are the risks of taking grape seed extract?

Side effects. Grape seed extract is generally considered safe. Side effects may include headache, itchy scalp, dizziness, and nausea.
Risks. People allergic to grapes should not use grape seed extract. If you have a bleeding disorder or high blood pressure, talk to your doctor before you start using grape seed extract.
Interactions. If you take any medicines regularly, talk to your doctor before you start using grape seed extract. It could interact with drugs like blood thinners, NSAID painkillers (like aspirin, Advil, and Aleve), certain heart medicines, cancer treatments, and others.
Given the lack of evidence about its safety, grape seed extract is not recommended for children or for women who are pregnant or breastfeeding.What are the benefits of grape seed extract2012-10-20 Blauer Portugieser anagoria
Grape seeds are linked to a number of
health benefits
Studies on animal models have revealed that the extract can be effective in treating heart diseases. Some experts think that grape seed extract could even have anticancer and cancer chemopreventive potential.

Over recent years there has been a great deal of research pointing to key therapeutic properties of the grape seed extract. Listed below are some of the key findings.

Health benefits associated with grape seed extract:

Healing wounds – Grape seed extract can heal dermal wounds.

A study, published in the journal Free Radical Biology and Medicine1, “provided firm evidence to support that topical application of GSPE represents a feasible and productive approach to support dermal wound healing.”

Improving bone strength – Including grape seed extract in your diet with calcium has a “beneficial effect on bone formation and bone strength for the treatment of bone debility caused by a low level of calcium,” according to research published in the Journal of Musculoskeletal & Neuronal Interactions.2

Preventing skin cancer – Grape seeds contain proanthocyanidins which can prevent the development of cancer.

A study, published in the journal Molecular Nutrition & Food Research3, found that grape seeds have properties that can reduce the severity of skin cancer. The researchers concluded that grape seed extracts “could be useful in the attenuation of the adverse UV-induced health effects in human skin.”
took 600 mg of grape seed extract every day for 6 months had less edema compared to those on placebo.
Preventing cognitive decline – Grape seed extract is very high in proanthocyanidins (oligomers of monomeric polyphenols) which may prevent cognitive decline.One study identified “a critical role for grape seed proanthocyanidin extract (GSPE) as a neuroprotectant in the hippocampus and in preventing cognitive loss with aging.”5
