Could it be okay to give grape seed extract to children?

Not recommended: There have not been enough studies to look at how grape seed extract can effect children. As pediatricians, we tend to be careful! Given the lack of evidence about its safety, grape seed extract is generally not recommended for children or for women who are pregnant or breastfeeding.

Grape seed extract: is generally reported to be a safe and well tolerated herb and no adverse events have been reported from it's use in my reference. However, safety and efficacy in children and its use during pregnancy and lactation is not well established. It may interfere with iron absorption, but definite evidence of this is lacking.
