Thanks. So many here focus on copper toxicity, but the reality is that copper deficiency is a much greater concern for many people, so unless someone here knows they have too much copper, then taking some copper supplements(don't overdo it though) is a good idea. I knew that copper is need to make hemoglobin, but didn't find out until today that copper is involved in thyroid function and in synthesizing phospholipids. I also knew that molybdenum supplements decrease copper levels, so I know that I need to take copper supplements. I am taking just 2.5 mg a day, and only on off days.

Vitamin B12 is also so important. I am using the sublingual tablets since I can't find the nasal gel, but dissolved a tablet today into a paste, and put it in my nose. It was more effective than under my tongue. I feel a surge of energy almost immediately from the B12, and using it nasally seems to work best. Many years ago I used the nasal gel, but it seems like the gel is no longer available.
