Some say being tired is caused by zinc excess but I believe if one is deficient they will have more circulating zinc in blood so when you supplement you will feel the side effects of zinc excess until it all reabsorbs into organs or wherever they go. This is why i also belive blood tests are inaccurate because your body will always make sure it has more vitamins in blood to be used where needed, where you need to check for where they are stored to get an accurate result.
