Possible Benefits

"In addition to herbs, many naturopathic doctors also believe certain nutrients can be helpful in quieting seasonal [allergy] symptoms. Among the most popular are grape seed extract and a flavonoid compound known as quercetin. Although both occur naturally in many foods -- and are especially abundant in red wine -- when used in supplement form they can be extremely helpful in reducing allergy symptoms, particularly in conjunction with vitamin C ..." - James Dillard, MD. at WebMD®

"Grape seed has been used as a source of Vitamin E (an antioxidant) and essential fatty acids. It has also been used for protecting against blood vessel disease (e.g., coronary heart disease), and for preventing certain liver problems and for preventing tooth cavities." - MedicineNet

What the Science Says

"Laboratory studies have shown that grape seed contains antioxidants-substances that prevent cell damage caused by free radicals, which are highly reactive molecules that can damage cell function. However, it is still unclear how grape seed might affect human health.

  • Grape seed extract has shown some beneficial antioxidant effects in preliminary clinical trials. However, few trials have looked at specific diseases or conditions, and little scientific evidence is available.
  • A study funded by the National Cancer Institute (NCI) found that grape seed extract did not reduce the hardening of breast tissue that can occur after radiation therapy for breast cancer.
  • NCI is also funding studies evaluating whether grape seed extract is effective in preventing breast and prostate cancers.
  • NCCAM is studying whether the action of grape seed extract and its components may benefit the heart or have protective effects in the brain.

Grape seed extract is generally well tolerated when taken by mouth. It has been used safely for up to 8 weeks in clinical trials.

  • Side effects that have been reported most often include headache; a dry, itchy scalp; dizziness; and nausea.
  • The interactions between grape seed extract and medicines or other supplements have not been carefully studied.
