Copper is not just used in wiring and electronics; it's also a vital mineral found in seafood, nuts, vegetables, fruits, and other foods. It's essential for growth and overall health. Copper helps in many bodily functions, including maintaining healthy bones, blood vessels, nerves, and immune function. It also helps with iron absorption and the formation of red blood cells. A lack of copper can lead to health issues, and you may need more as you age. Foods rich in copper include shellfish, seeds, nuts, and whole grains. If you're not getting enough from your diet, your doctor might suggest supplements. However, you should always consult your doctor before starting any new supplement. Too much copper can be harmful and lead to toxicity, which is rare but serious. Conditions like Wilson's disease can cause dangerous copper buildup, so people with such conditions should avoid supplements.
