> I tend towards hypOthyroidism and if I'm getting about/at least 8 mg of copper per day by drinking tap water and from food (the tap water estimate is based on something Larry said) then an 8:1 ratio of zinc puts me at between 50 and 100 mg. so I should be ok then.I went back and looked at the copper information again, and I missed a critical factor the first time around.....the graph of copper concentration in drinking water was *selected* to show the range of values for water supplies which exceeded federal guidelines.
That means I totally misinterpreted the information.
Please accept my apologies.
Total intake analyses show that most Americans take in no more than about 3 mg/day copper, including that from tap water.
That said, it would not be unreasonable to try and manipulate the zinc/copper ratio in order to accomodate individual health concerns, e.g. distortions of the ratio seen in thyroid dsyfunction.
