I started zinc because I was having some symptoms after starting up Vitamin D so having been slowly adding in the vit. D cofactors to try to get rid of these side effects hopefully. I read that too much zinc can cause hair loss but I also read a comment online where someone shared that when they started off with low doses (5 mg) and increased over time, the hair loss stopped. I've only been taking about 5 mg a day but have had very noticeable hair loss since. Any ideas? Should I take it less often? I feel I need the zinc as I do feel better (mostly mood issues) since beginning it. I am taking zinc picolinate.
