Benefits
What is copper bisglycinate good for?
It corrects copper deficiency and supports energy production, immune function, collagen, iron metabolism, and pigmentation. It's also used to offset the copper depletion caused by high-dose zinc.
Why does copper make me feel better?
Copper is required for the final step of mitochondrial energy production, so correcting a genuine deficiency can ease fatigue. It isn't a stimulant.
Does copper bisglycinate help with hair?
Copper is needed for pigment and collagen, so deficiency can cause graying and hair changes — but there's no good evidence it helps hair in people who aren't deficient.
What are the signs of copper deficiency?
Anemia (often resistant to iron), neutropenia, fatigue, bone fragility, hair changes, and in severe cases neurological symptoms.
Dosage & Timing
How much copper bisglycinate should I take per day?
For most adults, 1–2 mg per day — above the 900 mcg RDA and well below the 10 mg upper limit. Most products supply 2 mg per capsule.
When is the best time to take copper bisglycinate?
Any time of day, with or without food. The main thing is to keep it a few hours apart from high-dose zinc or iron.
Can I take copper bisglycinate at night?
Yes — it doesn't affect sleep, and nighttime is a good way to separate it from a morning zinc dose.
Safety & Interactions
Is copper bisglycinate safe?
Yes for most adults at 1–2 mg/day. The upper limit is 10 mg/day, and Wilson's disease is the key exception.
Is it safe to take copper every day?
Yes for healthy adults at a moderate dose. The body regulates copper, so daily use maintains status without building up.
Who should avoid copper bisglycinate?
People with Wilson's disease or copper-storage disorders. Those with iron overload or on long-term medication should check with a doctor first.
What should you not take with copper bisglycinate?
Keep it a few hours apart from high-dose zinc, high-dose iron, certain antibiotics, and very high-dose vitamin C.
Can I take copper bisglycinate with zinc?
Yes, and often you should. Separate the doses by a few hours and keep roughly a 10:1 to 15:1 zinc-to-copper ratio.
Which vitamin depletes copper?
High-dose vitamin C. Zinc, a mineral, depletes copper even more strongly and is the more common cause.
Can I take vitamin D with copper?
Yes. Vitamin D and copper don't compete for absorption and can be taken together.
Can I take copper bisglycinate with vitamin C?
Yes at normal doses. Only very high-dose vitamin C (1,500 mg+ daily) is a concern; space it a few hours apart.
Forms & Buying
Is copper glycinate the same as copper bisglycinate?
Almost always yes. "Bisglycinate" just specifies the 1:2 copper-to-glycine ratio, and most products labeled copper glycinate are the same compound.
Why is copper bisglycinate better than copper sulfate?
It's gentler on the stomach and likely better absorbed, because the glycine chelate shields the copper through digestion.
Where can I get copper bisglycinate supplements?
Many brands offer it — see our Buy page and check the label for a chelated form such as copper bisglycinate or TRAACS.
Diet
What food should I take copper bisglycinate with?
A protein-rich meal is ideal. Keep it away from high-zinc or high-iron foods at the same time.
What is the #1 food highest in copper?
Beef liver and oysters are the richest common dietary sources of copper.
