Hi all. I've been taking zinc supplements on and off for a few years, currently the dose is 15mg most days. My skin hair and nails are great and i often get compliments. Anyway, i've been feeling dizzy for a while and today had pressure in the top of my head (its still there.). Somehow my brain has linked this to zinc? I researched and realised women only need about 8mg a day, I take 15mg! Also I will get extra zinc from foods. Apparently 40/45mg is the limit an adult should take of zinc a day. I dont think ive been hitting the limit... but still im hugely freaking out that i have caused myself long term damage from taking zinc everyday! Ive convinced myself I might either go blind, destroy my brain or get really ill somehow. I have also associated this with my weird head pressure and dizzieness... whats going on? Im super scared:( i took supplements to avoid bad health originally,  never thought about it being too much of a good thing! I feel so stupid :(
