This mineral helps us regulate dopamine and serotonin levels, especially if we produce too much serotonin and not enough dopamine. Copper cooperates with vitamin C. But take vitamin c in the morning and minerals copper-zinc after dinner or later. Together, they strengthen collagen and make essential neurotransmitters, such as adrenaline, noradrenaline, and oxytocin. Copper and zinc have to be kept in balance as too much of one can deplete the other. copper:zinc ratio 1 copper :15 zinc. Copper Bisglycinate and Copper Chelate are both forms of copper supplements that are more easily absorbed by the body compared to other forms of copper. However, Copper Bisglycinate is a specific type of chelate where the copper is bound to the amino acid glycine, making it more bioavailable and less likely to cause gastrointestinal side effects. On the other hand, Copper Chelate refers to a broader category of copper supplements where the copper is bound to various amino acids or other organic molecules. Overall, both forms of copper supplements are effective in increasing copper levels in the body, but Copper Bisglycinate may be preferred for its superior absorption and tolerability. Seafood (oysters, lobster, squid, mussels, clams) Organ meats (cow liver, kidneys, or heart) Nuts (cashews, filberts, almonds, pistachios, pecans, macadamia nuts, peanuts) Beans (lentils, soybeans, navy beans) Unsweetened or semisweet chocolate or cocoa Enriched cereal Fruits and veggies Blackstrap molasses Black pepper Package was also good.

After a few weeks of regular use, I can confidently say this product delivers on its promises. The packaging was professional, and everything arrived in perfect condition. The formula is gentle but effective, with no side effects or discomfort. I’ve experienced noticeable benefits, from improved daily energy to better focus, and even small changes in overall mood. It’s reliable, consistent, and genuinely worth recommending. I don’t often feel this satisfied with wellness products, but this one has been an excellent experience.

I bought this product to support iron metabolism - I’ve learned that copper helps move iron to where it needs to be, so it actually works in the body instead of building up in the wrong places (but not in the blood), which can even be dangerous. Copper is also important for connective tissue, heart health, and maintaining healthy cholesterol levels. I found out the hard way that zinc depletes copper since it’s a copper antagonist - after taking too much zinc for a while, I ended up with copper deficiency. I liked the size and taste, it didn't cause any adverse symptoms.

This was a new brand for me to try. It seems like a quality brand. I was not disappointed. I liked the small mg dose size to being with to avoid nausea while building up. Adding this mineral could be a benefit to your health, as it is my understanding that a lot of people are deficient.

I'm taking 30mg of zinc, so I wanted to take 3mg of copper (as 1:10 ratio with zinc) but I felt very nauseous after this, I guess 3mg is a bit too much at the same time, so I'm taking half a tablet and this is better. My dad is also taking this alongside with glycine and lysine as natural collagen boosters.

Thank you to all the teams behind these products. Everything in my order arrived well-packaged, in perfect condition, and exactly as described. The quality across all brands — NOW Foods, California Gold Nutrition, and NaturesPlus — is consistently high. I appreciate the clear labeling, accurate dosages, and the frequent discounts. The products are easy to take, the packaging is user-friendly, and the effects are noticeable with regular use.

From the first impression, I could tell this was a high-quality product. The packaging was professional and secure, the product smelled fresh, and the dosage information was very clear. I’ve tried similar items from other brands, but the difference here is noticeable. Not only does it deliver what it promises, but it also feels like it’s made with genuine care. I particularly love that the serving size is practical and lasts longer than expected. After consistent use, I felt a boost in my overall health — more stable energy, better focus, and even an improvement in mood. This is easily a product I’d recommend to friends and family.

This has quickly become a staple in my daily routine. What impressed me most is the balance between effectiveness and comfort — I get real results without any negative side effects. The product feels pure, with a straightforward ingredient profile that builds trust. The capsules are easy to swallow, and there’s no lingering taste, which makes it effortless to take every day. Over time, I’ve noticed improvements not only in my physical energy but also in my overall sense of wellness. The price point is fair considering the quality and the generous amount in the bottle. Honestly, this is one of those products that I’ll keep coming back to because it just works.
