Ingredient Information
Summary
Copper sulphate anhydrous is a concentrated mineral compound used in very small, controlled amounts as a source of copper in some multivitamin and mineral formulations. Copper itself is an essential trace mineral, required by the body for a range of normal physiological processes.
In supplements, copper sulphate anhydrous is included only at low, regulated levels, where it contributes copper without significantly affecting taste, stability, or formulation balance.
Key Facts
- Type: Inorganic mineral salt (copper compound)
- Natural source: Occcurs anturally in foods such as shellfish, nuts, seeds, whole grains, and legumes
- Typical supplemental dose: Trace amounts ~0.3–1 mg copper per day
- Used for: Normal energy-yielding metabolism, iron transport, immune system function, nervous system support, antioxidant defence
- First discovered: Formally characterised in the 18th century, but known and used since ancient civilisations
What Is Copper Sulphate Anhydrous?
Copper sulphate anhydrous is the water-free form of copper sulphate (CuSO₄). Removing the water content creates a more stable and precisely measurable compound, which is why it is sometimes used in complex multivitamin and mineral blends.
Although copper sulphate is also used in non-nutritional settings, food-grade copper sulphate anhydrous is permitted as a copper source when used correctly and within strict dosage limits.
How It Works In The Body
Copper is an essential trace mineral that contributes to several normal bodily functions, including:
- Normal energy-yielding metabolism
- Normal functioning of the nervous system
- Normal iron transport in the body
- Normal immune system function
- Protection of cells from oxidative stress
Because the body only requires very small amounts, copper is typically included in multivitamins rather than taken as a standalone supplement.
Safety & Interactions
- Copper sulphate anhydrous is considered safe when used at trace mineral levels within regulated multivitamin and mineral formulations.
- Excess copper intake may cause side effects such as nausea, stomach discomfort, or digestive upset, particularly if taken at levels above recommended daily intake.
- Copper may interact with high-dose zinc supplementation, as excessive zinc intake can reduce copper absorption over time. Individuals taking high-dose zinc supplements should ensure their intake is appropriately balanced.
- People with conditions affecting copper metabolism, such as Wilson’s disease, should not take copper-containing supplements unless advised by a healthcare professional.
- Pregnant and breastfeeding women should consult a healthcare professional before taking supplements containing copper, to ensure intake remains within safe and appropriate limits.
Always consult your health practitioner before taking nutritional supplements, especially if you are taking medication or are under medical supervision. You should not take supplements as a substitute for a varied balanced diet or healthy lifestyle.
FAQs
Why is copper included in multivitamin supplements?
Copper is an essential trace mineral that contributes to normal energy-yielding metabolism, iron transport, and immune system function. Because the body only requires small amounts, it is typically included in multivitamins rather than taken as a standalone supplement.
Is copper sulphate anhydrous safe to consume?
Yes, when used in food-grade form and at trace mineral levels within regulated multivitamin formulations. Copper sulphate anhydrous provides copper in very small, controlled amounts that remain well within established safety limits.
Can I take copper alongside other mineral supplements?
Copper is often balanced with minerals such as zinc and iron in multivitamins. However, taking high-dose zinc supplements long term may reduce copper absorption, so it is important to maintain an appropriate balance or seek professional advice if combining supplements.
