Boron-Copper Connection re: Reversing the Gray Away Naturally

Regarding copper deficiency mentioned in the above article on gray hair

I found this (below) discussing the effect that boron has on raising copper levels (and many other good things it does) from a link from your recent post on the wayback machine:

…The following study is a gold mine. The study shows that boron supplementation increases estradiol and testosterone and for reasons given above I believe that these  results suggest that boron might be deficient in hyperthyroidism. Additionally boron was shown to decrease plasma concentrations of calcium. High calcium levels may be associated with increased heart rate. Since calcium and magnesium act as antagonists, this reduction of calcium by boron may allow magnesium levels to rise and thereby lower the heart rate and muscle cramps.

Additionally boron was shown to increase plasma copper, copper-zinc superoxide dismutase (SOD is one of the body's most important free radical scavengers), and ceruloplasmin (a protein which transports copper). Here is direct evidence that boron is essential for copper metabolism and therefore quite probably for the correction of hyperthyroidism and possibly hypothyroidism.

Furthermore, the study offers a possible explanation for why estrogen may slow thyroid function: it increases plasma copper, SOD, and ceruloplasmin. Boron also increased these variables whether estrogen was administered or not. 

This is excellent documentation to support my observations that boron was important in my recovery from hyperT.
