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.

I started on copper for my hyperthyroidism. I started to feel better a few months after taking it.

Bought this to see if my greying hair could be arrested. Hair is still grey but eye colour is much better (glossy shine instead of dull) and what I didn't expect was my varicose veins started clearing up after a couple of months. I'm sure there are other benefits but for these 2 reasons alone I'm re-ordering. Apparently copper depletion in our foods is really bad and that may be the cause, oh and PVC replacing copper pipes in our water supply doesn't help.

Since my diet may not include all the copper I need, added this supplement to keep grey hairs away. It works.

The copper pills were recommended by my eye doctor. In looking around I found that iHerb had the mg that I was told to get and the price was very reasonable. I have not been back to the doctor to see the effects they are having on me but but I am totally happy with what I received.. look for update after next appointment.

This is part of my dogs' supplements with the home-made natural food I prepare them. It is ground with other supplements and the dogs like it just fine.

If taking high doses of zinc for a long period of time copper supplementation may be needed.
