I Was Advised To Take A Vitamin Supplement Of Copper

I was advised to take a vitamin supplement of Copper around a month ago. About 2-3 weeks after taking the daily vitamin 2x daily I noticed I have bruising that appears on my arms and legs. The bruises disappear after a couple of days but are tender to the touch. Diabetes has been ruled out so I wonder what could cause bruising to appear and IF this could be related to the copper pills?
