Colloidal silver has been used in the medical field and in alternative medicine for centuries. In recent years, it has been gaining traction as a supplement that people may use for a variety of different purposes, from boosting the immune system to combatting specific ailments.

Colloidal silver is available from a variety of different sources.[4] However, people have also explored the idea of making this product themselves. In fact, if you look around on the internet, you will be able to find directions that allow you to make your own colloidal silver water at home. Nonetheless, it is important to note that the product you would create by following these directions is much more appropriate for cleaning your floors than it is for consumption. If you want to take colloidal silver by mouth, it is best to purchase a product from a reputable manufacturer instead.


How to Make Your Own Colloidal Silver at Home

Directions for making colloidal silver at home

In order to make your own colloidal silver at home, you will need:

  • 9-volt batteries with snap connectors or an AC/DC power supply of up to 30 volts
  • Black electrical tape
  • Crocodile clips
  • A fine silver coin or wire
  • Distilled water
  • Pots with a heat source or a 4-cup drip coffee maker that has a heating element beneath the pot.

Making colloidal silver at home is not recommended since the process of making it can be dangerous.

However, the procedure used typically involves using the power supply and the water to create a reaction that isolates the silver particles from the silver coin or wire which then dissolve into the water. The resulting product is typically yellow in color. If the elements are heated for too long, the product will take on a brownish or black hue instead, indicating that it has processed longer than it should have.

Problems with making colloidal silver at home

Problems with making colloidal silver at home

Being able to do something on your own, such as making colloidal silver, does not mean that you necessarily should do it. This is especially true if you plan to use the resulting product as a supplement. Some of the problems you encounter when attempting to make colloidal silver on your own include:

1. Lack of good quality supplies.

When making colloidal silver at home, you need distilled water, heating elements, and a host of other supplies. Unlike a reputable colloidal silver manufacturer, you will not have access to a laboratory or advanced equipment. When you are relying on supplies you can find or buy locally, you won’t be getting the best quality of colloidal silver from your efforts.

2. Danger.

Any chemical reaction comes with risks. When you are using batteries or other sources of power with water, you are exposing yourself to the possibility of an accident. Reactions will begin immediately as soon as you combine the elements together. This science is best left to the professionals.


3. Poor quality silver.

Making silver at home requires you to use a silver coin or wire. Because this is your active ingredient, its quality is of the utmost importance. However, it is impossible to know the exact purity level of these sources of silver. Because you can’t be sure of the silver’s purity, you cannot be sure of the purity of any colloidal silver you make using this process.

4. No control measures.

When a colloidal silver manufacturer creates their products in a laboratory, they used advanced equipment and careful procedures designed to ensure the efficacy of the final product. They measure each ingredient carefully, monitor every phase of the reaction, and perform an analysis on the final product to verify its quality. When making colloidal silver at home, you will not be able to implement any of these important control measures.

5. No knowledge of concentration, particle size, or other important characteristics.

Using this at-home method to make colloidal silver, you will not have any ability to measure the concentration of your final product.[1] Likewise, you will not know how much charge is present in the solution, if any, nor will you know the size of the silver particles. When you cannot measure these important characteristics, you cannot be sure the solution you have made will be safe or appropriate for consumption. In fact, it may even produce uncontrolled reactions in your body that could cause unwanted side effects, such as argyria.[3]

If you make your own colloidal silver at home and consume it in large amounts, you risk of side effects will increase even more. For this reason, we do not recommend attempting to make this product on your own.

The Bottom Line

The form of colloidal silver you get when you attempt to make your own supplement at home is never going to be of the same quality as the colloidal silver you can purchase from a reputable manufacturer. You may be able to use your homemade silver as a cleaning product, but you should never drink it.

Reputable manufacturers take steps to make sure the quality of their product is consistent and always up to the standard consumers expect. If you want colloidal silver that will be both safe and effective for your needs, you must purchase it from a reliable manufacturer with a good reputation for creating a quality supplement.
