I've read that for those of us with copper deficiencies that a polymorphism of the gene for a protein, Ctr 1, which is responsible for uptake of cu in the intestines, may be key. To bypass this problem am wondering aloud if taking a daily dose of liquid copper and holding-sloshing it around in the soft tissues of the mouth might not help overcome this problem. An alternate method would be to chew up a caplet of cu and hold it in the mouth for extended period. Any thoughts, comments? Thanks.
