Among various health products, grape seed extract is one of the most appealing. The functions advertised range from lowering blood lipids, reducing cholesterol, and fighting cancer to beauty enhancement and anti-aging, almost covering all trendy functions. However, no matter how lively the advertisements are, they cannot replace scientific facts. How reliable are those "functions" of grape seed extract?
The composition of grape seed extract is relatively complex, and it has not been subjected to systematic and sufficient safety research. We can only say that it is "likely" safe for the majority of people - an 8-week clinical trial did not find any harm, which can be considered as supporting this conclusion. However, considering that such research is still insufficient, from a cautious and prudent perspective, pregnant women, new mothers, and children should avoid taking it.
