Is it true that quercetin can impair iron absorption?

Quercetin is a polyphenol found in abundant quantities in apples, citrus, onions, green leafy vegetables, coffee and tea. Studies show coffee and tea can inhibit iron absorption, particularly the non-heme form of iron found in plants and grains. Plant forms of iron are as easily absorbed by the body as animal forms of iron. The recommendation for coffee and tea drinkers taking supplemental iron is to avoid these beverages for an hour before and after taking iron supplements. For this reason, we suggest Iron supplements (including multivitamins with iron) and Quercetin Complex be taken separately.
