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.

The first adrenal support that made a quick difference.

4 days ago

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

MRVerified Buyer

Steadier mornings within a fortnight.

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

ALVerified Buyer

Subtle, but real.

2 weeks ago

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

SKVerified Buyer

My clinician recommended it.

3 weeks ago

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

TPVerified Buyer

Recovery feels faster.

1 month ago

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

DVVerified Buyer

Does what it says.

1 month ago

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
