About This Product.

Thorne Copper Bisglycinate is a chelated copper supplement in which the mineral is bound to the amino acid glycine. This chelated form is generally considered more bioavailable than basic copper salts, meaning a greater proportion of each dose reaches the bloodstream. Copper is an essential trace mineral that plays a direct role in iron metabolism — it is required for the conversion of ferrous iron to the ferric form that transferrin can transport. Without adequate copper, iron can accumulate in tissue yet remain functionally unavailable, which is one reason copper deficiency and iron-deficiency anaemia can look similar on presentation.

Beyond iron metabolism, copper contributes to the synthesis of collagen and elastin, making it relevant for connective tissue integrity, skin structure, and wound healing. It also supports the antioxidant enzyme superoxide dismutase and plays a role in neurological function and melanin production.

This supplement suits people with confirmed or suspected copper insufficiency — particularly those supplementing with high-dose zinc long term, since zinc and copper compete for absorption and sustained zinc use can deplete copper over time. It may also be appropriate where diet is consistently low in copper-rich foods such as shellfish, nuts, and organ meats.

Thorne is a brand with a longstanding reputation in the practitioner supplement space, known for rigorous manufacturing standards and clean formulations. The bisglycinate form reflects a considered choice of mineral carrier for tolerability and absorption.

Frequently Asked.

Why would I need a copper supplement?

Most 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.

Is it safe to take copper alongside my zinc supplement?

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.

How long before I notice a difference?

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.

Who should avoid this supplement?

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.

Why choose bisglycinate over other forms of copper?

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.

Finally sorted my copper levels

4 months ago

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.

Exactly what I needed alongside my zinc stack

4 months ago

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.

Good product, pricey for what you get

5 months ago

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.

Solid trace mineral supplement

5 months ago

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

Recommended by my integrative doctor

5 months ago

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.

5 months ago

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.
