(03-05-07) Grape Seed Extract May Protect Against Skin Cancer

Extracts from grape seeds, rich in a substance called proanthocyanidin, could help prevent skin cancer by boosting the immune system.

In a new study, hairless mice supplemented with proanthocyanidins extracted from grape seed developed fewer skin tumors after exposure to UVB radiation.
A small but expanding number of other studies have shown similar results. A German study reported that subjects taking oligomeric proanthocyanidins had reduced reddening of the skin when exposed to UV radiation.

In the new study on mice, tumor incidence was reduced by 35 percent, tumor multiplicity by 65 percent, and tumor size by 78 percent at the highest dose of proanthocyanidin given to the mice.
Supplementation with grape seed extract appears to reduce the UVB-induced increase in the cytokine interleukin-10 (IL-10), which suppresses immune function. At the same time, it increased production of IL-12, which stimulates the immune system.
