Frequently asked questions

Colloidal silver is a liquid made of tiny particles and ions of silver suspended in purified water. Ours is made by low-voltage electrolysis: two 99.99% fine silver electrodes are placed in deionised water and a small, controlled current passes silver into the water. Nothing else is added.

ppm stands for parts per million. 10ppm means there are about 10 milligrams of silver in every litre of solution (10 mg/L). We measure the concentration of every batch before it's bottled.

No. Our colloidal silver is not a licensed medicine and we don't make any medical or health claims about it. It is not intended to diagnose, treat, cure or prevent any disease. If you have a health condition, are pregnant or breastfeeding, or take medication, speak to a doctor or pharmacist first.

Only deionised water and silver. There are no salts, proteins, stabilisers, preservatives, colourings or fragrances.

Silver solutions are best kept away from light. Dark violet glass blocks most visible light, and glass doesn't leach anything into the solution the way some plastics can.

Keep the bottle closed, upright and at room temperature, away from direct sunlight and strong magnetic or electrical fields such as the top of a microwave. Don't refrigerate or freeze it. Always keep it out of reach of children.

Stored as above, an unopened bottle is best used within two years of the production date printed on the label. Once opened, use clean droppers or decant carefully to avoid contaminating it.
