In my research I discovered our bodies need copper for blood pressure control, cholesterol and glucose metabolism, and enzyme function.
Most people get enough copper from their diet according to U.S. News & World Report. The best sources of copper are found in shellfish, seeds, nuts, organ meats, wheat bran cereals, whole grain products and chocolate. Smaller amounts of copper are found in dark chocolate, tofu, avocado, whole wheat pasta, millet, salmon, figs, spinach, ground turkey and asparagus.
When I see the green marks on my skin from wearing my copper jewelry, I like to think that means it is working. Placebo effect or not, I believe it helps my aches and stiffness.
I have found that using Ultra Ajax dish soap as a hand soap in my kitchen also keeps my copper ring shiny without tarnish. While on vacation, not using Ajax dish soap, my ring started to tarnish. It shined right up after a few times of washing my hands with Ajax dish soap. I haven’t tried it on my bracelets, I tend to like the natural copper look on them.
