A growing number of studies show that grape seed extract has powerful anticancer properties that are effective against many types of cancer, including:

•Breast cancer

• Prostate cancer

• Colon cancer

• Bladder cancer

• Leukemia

• Lung cancer

• Adenocarcinoma of the GI tract

•Head and neck cancers

•Melanomas

•Pancreatic cancer

•Skin cancer

The benefits come in the form of both prevention and treatment of existing cancers.

Grape seed extract (GSE) contains a complex mixture of oligomers of procyanidins, gallic acid, catechins, and epicatechin. The most powerful anticancer compounds in grape seed extract are the procyanidins and gallic acid.

One of the procyanidins, called proanthocyanadin, has been found to inhibit cancers in a number of ways, including suppressing cell-signaling mechanisms essential for cancer cell growth and invasion, inhibiting inflammatory cell-signaling, inhibiting the release of inflammatory cytokines, activating apoptosis (cell death) mechanisms called caspases and BAK activation, inhibiting cell cycle regulating proteins, and acting at other cancer cell checkpoints.

Compounds that inhibit a number of critical cancer mechanisms all at once are much more likely to control a cancer than chemotherapy drugs that attack only one or two mechanisms — which cancer cells can easily overcome.
