Can taking multimineral supplement cause easy bruising?

Yes: There are several vitamins and herbal supplements which can lead to increased bleeding including vitamin e, echinacea, ginko, and ginseng.

It depends: It depends on what's in the supplement you're taking. As my colleague has shared, some products do contain herbal and other components that can lead to easy bruising. Bleeding and bruising are unlikely if the "multimineral" truly has only minerals in it, though. Read your label and see.
