Grape seed extracts and estrogen modulation.
One of the many benefits of grape seed extract is its ability to modulate estrogen biosynthesis. It achieves this capability via inhibiting a specific enzyme referred to as aromatase. Aromatase is an enzyme responsible for converting androgen substrates to estrogen.
The high levels of procyanidin dimers, especially the B dimers, found in grape seed extracts have been shown to be potent inhibitors of aromatase. Since aromatase is highly expressed in breast cancer tissue compared with normal breast tissue, data from both in vitro and in vivo studies suggest that grape seed extracts can act as chemopreventive agents against breast cancer by suppressing in situ estrogen biosynthesis.
