For those people trying to lower their iron levels and not being able to take aspirin or vitamin E, this may be a safer alternative. I am not sure cranberries are very Peaty, but they are probably safer in terms of causing GI bleeding than both aspirin and vitamin E.

"...The altered expression of genes associated with iron transport was consistent with the strong iron chelating capability of proanthocyanidins, a major constituent of cranberry juice. The iron depletion effect was confirmed by adding exogenous iron to the growth media. This addition partially reversed the inhibitory effect on bacterial growth observed in the presence of cranberry juice/extracts."
