Thorne Copper Bisglycinate provides copper bound to the amino acid glycine, a chelated form chosen for its good absorption and tolerability. Copper is an essential trace mineral with several established roles in the body.
Take one capsule daily, or as directed on the packaging. Copper is best taken away from high-dose zinc supplements, as the two minerals compete for absorption. If you take other trace minerals, check with a practitioner about timing. Do not exceed the recommended daily dose.
Copper contributes to the maintenance of normal connective tissues and to normal iron transport. It also contributes to normal functioning of the nervous system, normal energy-yielding metabolism, and normal hair and skin pigmentation, and it helps protect cells from oxidative stress through its role in the enzyme superoxide dismutase.
Most people get enough copper from food - shellfish, nuts, seeds and organ meats are the richest sources - but there are two common situations where intake falls short. The first is long-term use of high-dose zinc supplements: zinc and copper compete for absorption in the gut, and sustained zinc use can gradually deplete copper. The second is a diet consistently low in copper-rich foods.
Who it suits: people advised by a practitioner to supplement copper, and those taking high-dose zinc over extended periods. As with any mineral, more is not better. Do not exceed the recommended dose, and check with your doctor first if you are pregnant, breastfeeding or managing a medical condition.

Your first order creates it. Add your blood results or a wearable, and a doctor can recommend what suits you.
Sign inMost people get adequate copper through diet, but deficiency can occur with sustained high-dose zinc supplementation (zinc competes with copper for absorption), very restrictive diets, or certain malabsorption conditions. A blood panel is the most reliable way to confirm whether supplementation is warranted.
Copper and zinc compete for absorption in the gut, so it is generally advisable to take them at separate times of day rather than together. If you are supplementing both, a practitioner can advise on the appropriate ratio and schedule for your situation.
Trace mineral repletion is gradual. If you have confirmed low copper, meaningful changes in relevant markers — such as iron metabolism or energy — typically take several weeks of consistent supplementation. A follow-up blood panel is the most objective way to track progress.
People with Wilson's disease, a condition of copper overload, should not take copper supplements. It is also worth checking your diet and any other supplements for existing copper content before adding this, to avoid unintentionally exceeding recommended intake.
Bisglycinate is a chelated form, where the copper is bound to glycine. Chelated minerals are generally better absorbed and tolerated than inorganic forms such as copper oxide or sulphate, which is why this form is commonly preferred in practitioner-grade supplements.
Overall

Been taking zinc for about two years and my GP flagged that my copper was on the low side. Started this a couple of months back and my last bloods looked much better. Small capsule, easy to swallow, no stomach upset at all — which I did have with a cheaper form I tried before.

I take fairly high-dose zinc for immune support and my nutritionist flagged the copper depletion risk ages ago. This ticks all the boxes — clean ingredients, no fillers, and I trust the manufacturing behind this brand. Been on it three months, feel good.

No complaints about how it works — I've been taking it for a few months alongside my iron protocol and my ferritin has improved nicely. My only gripe is that the bottle contains 60 capsules, which at this price feels a bit stingy compared to similar chelated options. Will keep buying, but wish it stretched further.

Does exactly what it says. No smell, no aftertaste, sits fine on an empty stomach. I take it mid-morning with water.

My doctor suggested this specifically because of the chelated form — she said it's gentler on the gut and better absorbed than standard copper supplements. A few weeks in and no issues at all. Very happy with it.

Switched from a cheaper copper oxide supplement after reading about bioavailability differences. This one sits much better with me and I've noticed my energy feels more consistent — hard to say if it's purely this but I've made no other changes.
