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've been taking this product from time to time in order to prevent premature graying of my hair and I guess it works. I like the small sized capsules which are easy to swallow.

I like these. The caps are small (which implies less fillers). Good quality and value.

I love that these copper pills are quite tiny capsules as it makes them easy to swallow! I used to have other brand (not from iherb) big, bulky and thick tablets that were so difficult to get down. They even had rough edges. I don't struggle with huge capsules as long as they are soft, but I love how these capsules are actually tiny compared to most others!
