It was interesting that chelated zinc/copper gets into the blood by a different route.

What I was thinking of was all these "cold" products out now with zinc. It really has become the supplement du jour. And if you think about it, when you've got a cold you really need the white blood cells around, if you're copper deficient because you take zinc, you could be in for a longer cold.

Also, I found the hints about copper deficiency interesting. I'm nuts for nuts and probably get at least 1 oz (more most likely) every day. I just read an article about how the EFA profile in nuts is so ideal, and now this about copper. I guess I shouldn't beat myself up over eating nuts.
