"After my doctor said my copper levels were low, I started taking these capsules daily. Even though I'm usually sensitive to supplements, this one was gentle and didn’t upset my stomach. Bloodwork confirmed my copper improved, so I’m definitely a fan."

"I use Pure Encapsulations Copper Glycinate mainly for energy support and to help with grey hair. I appreciate that it’s non-GMO, vegan, and easy to take. Although it's a bit pricey, I make it last by taking it every other day. Overall, it’s a high-quality addition to my daily routine."

"I've noticed a clearer mind and improved focus since I started taking this supplement. The price is also very reasonable, making it a great deal for anyone looking to support their mental clarity."

"I appreciate that this copper glycinate is gentle on my stomach and hasn't caused any digestive issues. Plus, I've felt a subtle boost in my energy and even noticed a healthier glow to my skin. The value is excellent, and I trust the NOW brand; just keep in mind the pills are a bit on the larger side."

"I started using this to see if it would help slow down the appearance of grey hairs, and after consistently taking it, I did notice fewer new greys. When I stopped for a couple of months, a lot more greys popped up! While it's not a miracle cure, it seems to make a difference for me."

"I've tried several copper supplements, but Nutricost's copper glycinate capsules stand out for their high bioavailability and gentle effect on my stomach. After taking them consistently, I've noticed better energy levels and overall well-being. I appreciate that the capsules are easy to swallow and have no aftertaste. It’s also great that the bottle provides a four-month supply at a reasonable price. The only thing I’d love to see is more detailed sourcing information for the ingredients."

"After using these capsules for over a year, I can say they've boosted my immune system and even helped me heal minor cuts faster. I trust Nutricost's consistent quality more than other brands I've tried. Just remember to balance your copper intake with vitamin K for best results. For me, this is the best supplement company out there."

"I researched supplement brands for days and settled on Nutricost because they provide test results for every batch—just contact them with the lot number. It reassures me that heavy metals are well below safe levels. Few supplement companies are as transparent or trustworthy in my experience. Highly recommend!"

"I chose this supplement because it's a low dosage that works well with my multivitamin. The brand reputation gives me confidence that the ingredients are clean and high quality. The tablets are small and easy to take, and I'm already seeing less gray hair and improved alertness. With 300 tablets, it's a great value and will last a long time."

"We've relied on this brand for years and always get good results. I appreciate that the tablets are easy to swallow, and I trust Swanson for supplements. Taking copper with zinc is effective, so we'll definitely keep buying this product."

"The product itself is good and I've felt some positive effects, but the packaging arrived bent. Otherwise, it's working well for me."

"I've added Bronson Copper Glycinate 3mg to my daily supplements, and I really appreciate the chelated glycinate form for better absorption. The small tablets are easy to take, and they’re gentle on my stomach. Plus, knowing it’s vegetarian and non-GMO gives me peace of mind about its quality."

"I've been using this supplement for a long time and find it easy to swallow. Plus, my blood pressure has returned to normal since adding it to my routine."

"I appreciate that these capsules are easy to swallow and gentle on my stomach. I started taking them to help balance my zinc and copper levels, but after a week I noticed some trouble sleeping, which I later learned could be a symptom of copper toxicity. I decided to stop for a bit and see if things improved."

"I'm thrilled with this purchase because it’s hard to find copper supplements at a reasonable price. Compared to my local vitamin store, I saved nearly $100 and got more pills. The capsules are the same size and coating as I’m used to, and they were delivered to my door in just two days. I’ll be sticking with Amazon for supplements from now on!"

"The only downside for me was the strong, unpleasant smell of this copper supplement. Luckily, it was an inexpensive purchase, but unfortunately, I ended up throwing the bottle away."

"I've noticed a remarkable improvement in my hair and energy after taking these daily with zinc. My cold hands and feet have disappeared, and I wish I had learned about copper sooner."

"The capsules are simple to take, affordable, and work as intended. The quality meets my expectations, and I'd definitely consider purchasing again."

"I appreciate that this brand uses glass jars and provides consistently high-quality pills. I've been a loyal user for years, with no side effects at all—definitely recommend!"

"I've struggled with painful muscle spasms and frequent night awakenings due to nerve damage from back surgeries. Since I started using this product, I've noticed a significant decrease in muscle cramps and now experience much better sleep, waking up far less throughout the night. This supplement truly made a difference in my daily life."

"For years, I dealt with anemia and poor sleep that iron supplements never resolved. After learning about copper's role in oxygen transport, I switched to this product. Now, my energy is higher, breathing easier, and my sleep has improved. As a bonus, I’ve noticed slower greying of my hair. Highly recommended!"

"Minerals are essential for overall health, especially as I get older. Since using this product, I've experienced better sleep, increased energy, and even improved hair color. I make sure to keep it stocked, and it’s become a key part of my wellness routine."

"I've been using this copper supplement for a few months and I’m honestly impressed with the quality and results. The liquid ionic form absorbs quickly, and I've noticed better energy and improved skin since making it part of my routine. The dropper makes dosing simple, and I love that there are no artificial ingredients. This has become a core part of my wellness regimen!"

"After trying expensive copper water and bulky bottles, I found this supplement and it’s so much more convenient. I can add it to anything—coffee, smoothies, soup—and control my intake easily. No more hassle, no high cost, and I’ve stayed cold and flu free. For anyone wanting a simple, effective copper supplement, this is it."

"I do find the taste tough to handle, so I mix it with my liquid multivitamin to help. Still, it's worth it for the health benefits—sometimes good things just don’t taste great."
