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.

Thanks for your feedback!

Much better than copper gluconate for me

Posted by iHerb Customer on Mar 29, 2014 | Verified Purchase

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.

Thanks for your feedback!

Stomach-gentle copper

Posted by iHerb Customer on Nov 03, 2010 | Verified Purchase

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.

Thanks for your feedback!

very good

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.

Thanks for your feedback!

My intestines didn't like it

Posted by iHerb Customer on Dec 19, 2013 | Verified Purchase

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.

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

Thanks for your feedback!

If you supplement with zinc, you should also take copper... or so I've read.
