Straight answers, no hype
This is our plain-English answer hub for the questions we are asked most. We sell colloidal silver for external use only and we make no medical claims. Where a question deserves a fuller treatment, we link to a dedicated guide.
Honest answers to common colloidal silver questions: what it is, argyria and the blue man, safety, the MHRA, storage and how to choose a strength.
If you are new to colloidal silver, the best place to start is our complete colloidal silver guide. This page answers the specific questions people ask before and after they buy.
UK-made colloidal silver, in dark glass
Double-purified water — reverse osmosis, then distilled — with real silver. Made in the UK.
What is colloidal silver?
Colloidal silver is a suspension of tiny particles of pure silver in purified water. That is the whole of it — silver and water, nothing else.
Ours is made in the UK and sold for external use only.
For the full background, see our complete guide and what is colloidal silver?.
How is it made, and what water do you use?
The water is where we put the work. Most colloidal silver is made with water that has been through one purification step, if any.
We use two. First, reverse osmosis forces the water through an ultra-fine membrane that strains out dissolved minerals and impurities.
Then we distil what is left — boiling it to vapour and re-condensing it, so only the cleanest water carries through. Two stages, every batch, before a single particle of silver goes in.
After that, it is bottled in dark glass rather than plastic to keep light off the contents.
Will colloidal silver turn me blue?
This is the question behind almost every other worry, so it is worth answering carefully. The blue colouring people picture is a rare, permanent condition called argyria.
It is genuinely real — but it comes from prolonged, heavy intake of silver over a long period, not from sensible use.
The best-known case is Paul Karason, the “blue man”.
By the accounts he gave, he drank around ten ounces of homemade colloidal silver a day — sometimes twice a day — for more than a decade, and also applied it to his skin daily.
That is an extreme quantity, self-made at unknown concentration, sustained over many years. The reassurance here is the sheer scale and duration involved, not the method.
We would not want to pretend any use is entirely without risk: localised skin discolouration has, very rarely, been reported with heavy topical use too.
But used sensibly and externally as intended — nothing like the amounts above — it is a very different picture.
We cover the science and the story in full in will colloidal silver turn me blue?.
Is colloidal silver safe?
We sell colloidal silver for external use only and we do not make medical claims, so we will not tell you it does anything in particular.
What we can say is that it should be used sensibly and as intended, kept away from children, and not swallowed. If you have a specific health concern, speak to a qualified professional.
Our fuller piece, is colloidal silver safe?, sets out what is and is not known.
Colloidal silver and the MHRA
In the UK, colloidal silver is not a licensed medicine, and it is not sold or marketed as one. We are not a pharmacy or a medical provider.
We offer colloidal silver as a product for external use only, and we are careful never to make medical or treatment claims about it.
Our guide colloidal silver and the MHRA: where we stand explains our position plainly.
How should I store and handle it?
Keep it in its dark glass bottle, somewhere cool and out of direct sunlight, with the lid closed. The dark glass already does a lot of the work by keeping light off the contents; a cupboard finishes the job.
There is no need to refrigerate it.
For the detail, see how should I store and handle colloidal silver? and how to store colloidal silver.
Which strength, format and size?
We keep this neutral on purpose and let you decide. We offer 10, 100 and 200 ppm; a 100ml dropper, a 100ml spray and a 500ml refill.
As a rough rule of thumb, the 100ml bottles are the everyday application bottles, and the 500ml is the refill you top up from.
Our ppm explained and dropper, spray or refill guides walk through the choices, and you can compare everything in the shop.
Do you make any health claims?
No. We do not claim colloidal silver treats, prevents or cures anything, and you will not find such claims anywhere on our site.
We sell a simple, well-made product for external use only, are open about how it is made, and leave the decision to you.
