Colloidal silver is a liquid that contains microscopic silver particles. It is made by exposing pure silver to low-voltage electricity and/or certain chemical reactions while immersed in a liquid. This process drives millions of tiny silver particles to become dispersed through the liquid, turning it into a colloid.
In supplement form, colloidal silver is found in liquid dropper bottles and occasionally in premade capsules. It’s commonly used as a immunity aid, although the clinical evidence is mixed.
Best Colloidal Silver Supplements of 2021
OUR TOP PICK
OUR TOP PICK
This colloidal supplement comes from a particularly good, and well established brand.
What we love about this supplement is how it uses both pharmaceutical grade and pharmaceutical grade water rather than being electrically processed, like many of its counterparts.
This supplement’s dosage is a whopping 25 times stronger than most other colloidal silver solutions, so a little really does go a long way.
The colloidal silver particles contained are incredibly small, which means that they’re very easily absorbed into the bloodstream and made readily available for your immune system.
There are no animal by-products in this supplement whatsoever, which is always a plus, especially for vegans and vegetarians.
And no other hidden nasties either - it contains nothing but colloidal silver and water.
We also love the affordability of this supplement - great price. And battery yet, if you buy through Amazon, it’s available in their “subscribe and save” scheme, where you save money on both your initial purchase, and on all your repeat deliveries.
- Concentrated amount
- Very affordable price point
- pharmaceutical grade ingredients

Here’s another great colloidal silver supplement.
Again it comes in liquid form which really helps to allow for fast absorption into the bloodstream, and more importantly, to the thyroid gland.
There are just two ingredients in the bottle, and that’s the colloidal silver, and pure water.
There are no hidden nasties to worry about, it’s completely free of artificial ingredients or flavors, and is also gluten free and is suitable for vegetarians and vegans alike.
Due to the very small particle size at just 0.8 nanometers, you get even faster absorption than with its counterparts. And the silver ions are all positively charged which is exactly what you need for the silver to be effective.
You get 48 servings in a bottle, which is plenty. And the concentration is set at 30 ppm, so you get the perfect balance between high effectiveness and truly safe doses.

If you know you’re going to need a lot of a supplement like colloidal silver, it is possible to make one large purchase, rather than repeatedly having to take frequent smaller purchases.
Like you can with this particular supplement which comes in a huge 1 gallon bottle.
It contains just two ingredients, colloidal silver particles and pure vapor distilled water. This way you can rest assured that there are no hidden nasties, like additives, preservatives, or allergens. It’s even suitable for vegans.
As a liquid rather than a tablet or pill, it gets 98 percent absorbed straight into the bloodstream in less than 5 minutes. To put that into perspective, the pill counterpart only absorbs 18% into the bloodstream, and has to go through a longer digestive process which can take up to half an hour.
It comes complete with a 30 day money back guarantee, so if you don’t like the taste too much, then you can simply report the issue and get your money back.
To be fair, this supplement pretty much ticks all the boxes. You get great quality, with it being made under strict GMP standards. And it’s a very potent little supplement, but at the same time is also completely safe to consume.
- Very large container, will last
- Suitable for vegetarians and vegans
- 98 percent absorbed into the bloodstream
- 30 day money back guarantee
- Amazon only seems to have the 1 gallon version in stock, which makes it expensive

It’s suitable for vegetarians, and is also free of artificial ingredients, sugar and salt.
What we like the most about this brand of colloidal silver is that the manufacturers are keenly aware of the potential dangers of taking too much colloidal silver, as you can see by their instruction not to ever take it for more than 10 days in a row, and for no more than 20 times per month.

Here’s another great colloidal silver supplement, this time in a 16 fluid ounce bottle
It contains very few ingredients, just the colloidal silver along with the ozonated distilled water.
As such, there are no hidden nasties to worry about. This also means there are no animal by products to worry about either, so it’s perfectly suitable for vegetarians and vegans to use, which has also been verified by the American Vegetarian Association.
And it’s set at the perfect dosage. The 30 ppm concentration should be plenty for one teaspoon a day at the start of an illness, which you should then taper off as instructed to avoid having dangerous levels in your bloodstream.
This concentration also helps with effective absorption into the body too.
The title on the Amazon page is a little deceptive. This is not a spray bottle.
- Perfect concentration
- Comes in a large bottle
- Suitable for vegetarians
- Be careful not to exceed the recommended dosage

How great is it to get colloidal silver supplements in the form of a spray! You’ll never have to worry whether you’ve taken too large a dose.
At the same time though, you can rest assured that you’ve taken enough of it to be effective.
You get a 10 ppm dosage in each spray, which is safe to take every day for a week, and by the end of that week you should be feeling a lot better.
The amber colored glass defends the supplement from direct sunlight, and ensures that the silver compound remains stable.
What we love about it is the unprecedented particle size. Each particle is 0.8 nanometers small. This makes it particularly fast and easy to be absorbed into the bloodstream. So the silver can get to work on your immune system straight away.
There’s only two ingredients in the bottle, namely 99.999% pure silver and pharmaceutical grade purified water. So, there are no hidden nasties to worry about. No gluten or other allergens, and it’s vegan too.
It’s available in two different size bottles, one fluid ounce or two fluid ounces, both of which are small enough to easily slide into your purse and take out with you.
