What ppm means
PPM means parts per million — the way colloidal silver concentration is described. It simply tells you how much silver is suspended in the water. We offer 10, 100 and 200 ppm, all made the same way, and sold for external use only.
This guide covers what ppm means in colloidal silver, whether a higher number is better, the difference between 10, 100 and 200 ppm, and how to pick.
PPM is the number you will see next to every colloidal silver, and it is the one that confuses people most.
Here is what it means in plain terms — and why we leave the choice of strength entirely to you. For the wider picture, see our complete colloidal silver guide.
UK-made colloidal silver, in dark glass
Double-purified water — reverse osmosis, then distilled — with real silver. Made in the UK.
What does “ppm” mean in colloidal silver?
PPM stands for parts per million — it tells you how much silver is suspended in the water, nothing more.
A higher ppm simply means more silver per unit of water. It does not imply anything beyond that.
Is higher ppm colloidal silver better?
Not necessarily — ppm on its own doesn’t tell you a product’s quality.
The number describes concentration, not how the silver is made or how finely it is dispersed. That is why we don’t push a higher number as “better”.
What’s the difference between 10, 100 and 200 ppm?
Only the concentration — everything else is identical.
- 10 ppm — the lowest concentration we offer.
- 100 ppm — a middle concentration.
- 200 ppm — the highest concentration we offer.
The number is the only thing that changes between them. The water, the silver and the dark glass are exactly the same.
Which ppm strength should I choose?
Whichever suits you — we don’t decide that for you.
Some people prefer a lower concentration, others a higher one. Both are equally valid, and whichever you choose is sold for external use only.
Is ppm the same as format and bottle size?
No. Strength (ppm) is a separate choice from format and from bottle size.
You pick a strength, then a format — dropper, spray or refill — and a size. Our dropper, spray or refill guide covers the formats.
You can compare every strength and size in the shop, or build a mixed pack and save with our bundles.

Why buy from Health is a Choice
We make our colloidal silver in the UK, the way we would want it for our own family. We don’t purify our water once — we do it twice.
It is first cleaned by reverse osmosis, then distilled on top of that, before we suspend real silver in it and bottle it in dark glass — never plastic.
