Be careful - copper can be inflammatory so only take this if you know you're low in copper. I found it very stimulating as well - couldn't fall asleep. But this is a very good brand. Copper is mildly estrogenic (as is manganese). It needs to be kept in balance with zinc in the body - too much of one can cause a relative deificiency of the other. Hair testing and blood tests help determine your levels.

Much better than copper gluconate for me

Posted by Reviewer2905899 on Mar 29, 2014

A blood test showed that I needed more copper. (Every other nutrient seemed fine on the nutrient blood test.) I tried copper gluconate and felt worse. Then I tried NutriCology's copper sebacate and definitely felt better. It is my understanding that this form is more readily absorbed by the cells. If the copper just sits outside the cells, that isn't good for you. I've not tried other brands of copper sebacate.

I supplement with copper to balance out my increased supplementation of iron and zinc. This chelated form of copper seems to be well absorbed by my body.

Stomach-gentle copper

Posted by Reviewer1908266 on Nov 03, 2010

Sometimes copper gluconate can upset my stomach. When I thought I needed more than 2 mg, I tried this copper sebacate. Easy to take, no digestive problem. After awhile I didn't need 4 mg any longer, but I'd take this again gladly if I needed to.

Not quite so easy to digest, but still an asset.

My intestines didn't like it

Posted by Reviewer3307313 on Dec 19, 2013

I've tried this several times, and it always caused me intestinal upset. My guts are on the sensitive side though. The odd thing is, I finished a bottle of another brand of copper sebacate and didn't have the same problem. I currently take copper bisglycinate without this issue.
