Is it harmful to take 30mg of zinc in the 2 week wait, if the recommended dose is 15mg? I have 15mg in my multi vitamins, but I usually take an extra 15mg in the 2 weeks or so when I know I'm not pregnant, to try and keep my skin clear. But I've been breaking out alot more lately, so I want to take the extra one everyday. Do you think it will be ok?
