Problems with taking iron and Vitamin c at the same time---Link---Multi-vitamin issues?

Ran across this article that states "The damaging effects of a high intake of either iron salts or vitamin C alone warrants serious consideration. However, in tandem this cocktail is potent. Uncontrolled interaction between vitamin C and iron salts leads to oxidative stress." "Co-supplementation of ferrous salts with vitamin C exacerbates oxidative stress in the gastrointestinal tract, predisposing individuals to ulceration, inflammatory disorders, and exacerbation of existing chronic disorders and may cause cancer." Less than 50%. What do you think of this?
