Have been using this brand of copper for several years, but hadn't taken in a long while. It stopped the dizziness and nosebleeds. I was deficient because of zinc use without copper. Great product.

PERFECT - Tiny capsules that work - SEE NOTE RE GREY HAIR

GREY HAIR - if you're taking copper for grey hair, it pays to be aware that copper - in the presence of low methionine and/or glutathione - could either not work, or cause MORE grey hair. LOW METHIONINE can lead to a build up of hydrogen peroxide in hair follicles, reduced tyrosinase effectiveness, and a gradual loss of hair color - refer PUB MED 1-9-2-3-7-5-0-3. COPPER is a component of Cu-Zn SOD, which catalyses superoxide radicals into oxygen - OR - hydrogen peroxide. The outcome can be affected by low levels of methionine (as above), enzyme inhibition OR glutathione and/or its co-factors. GLUTATHIONE PEROXIDASE is needed to reduce free hydrogen peroxide to water. It's a SELENIUM-containing enzyme, NAD is a co-factor. INSOMNIA - Are you a night owl? Low copper can cause insomnia. HISTAMINE ISSUES? Copper is a natural anti-histamine, required for Amine oxidase (aka histaminase/diamine oxidase). I don't understand why anyone would chelate copper into oblivion unless proven copper dysfunction (e.g. Wilson's Disease). Many physiological processes rely on copper (e.g. Tyrosinase, Nitrite reductase, Catechol oxidase, etc). If you find yourself with CFS/ME, MCS, food intolerances - (histamine aside) consider things such as foods that are known to contain enzymes like Polyphenol oxidase, which could exacerbate low copper issues. Also be aware of copper antagonists/synergists, enzyme inhibitors/hidden chelators such as EDTA, citrate/citric acid. If this review was helpful to you, please click YES below - thank you.

Helps restore mineral balance when removing toxic metals with seaweed

It's best to keep copper in the "Goldilocks Zone", as either too much or too little is bad. I take WITH FOOD once every 1-2 weeks when feeling run down. If I get brief nausea then I know I'm topped off. I'm not sure the average person needs this, especially if your water lines are copper.

You need this if you take Zinc

3 people found the following review helpful

You need to take 2 mg of Copper daily when you use Zinc daily. So, for I know 2 mg is recommended and this supplement has this 2 mg. So I think this is the best one for me. The capsules are small and very easy to swallow. And they have a nice minty blue color...but that's not important ofcourse..
