Colloidal Silver is a mineral solution containing silver ions & very small charged silver particles suspended in a medium (distilled water). As the particles have the same electrostatic charge (Zeta potential), they repel each other and this keeps them in uniform suspension throughout the medium. This is why it is called a colloid. It is not a medicine, it is a mineral solution with interesting positive effects.

We make Electrically Isolated Colloidal Silver (EIS) which means it contains both ionic and particulate silver at an approximate ratio of 80% ionic & 20% particulate silver. It is important to understand that the silver particles are not dissolved but held in suspension by electrostatic charges. Without them, it would not be a colloid and not Colloidal Silver. Although silver ions are important, a 100% solution of silver ions is NOT Colloidal Silver.

Various names have been used to describe Colloidal Silver, such as Silver Sols. It is sometimes referred to as "Nano Silver" as the particles are in the range of 1 to 40 nm (Nanometres) or .001 to .04 um (Micrometres).

Many sites use marketing names and technology. The Latin word for silver is Argentum and various brand names can be found, which are generally just marketing ideas. Another word that crops up is "Oligodynamic" and the words "Bioavailable" are often used. We don't believe in marketing because this is a natural substance given to us by nature. It is not for us to rebrand it, we just manufacture it naturally & carefully then make it available as Colloidal Silver.

Oligodynamic is an antimicrobial effect of metal-ions in relatively low concentrations. See Wikipedia.

Bioavailibility describes the fraction of dose of medication that reaches the systemic circulation. See Wikipedia.

It is very important that you understand there are products containing silver salts and proteins (MSP or CSP) that are also called Colloidal Silver. This is untrue and very misleading. These have been proved to develop Argyria and could also be inherently dangerous and must be avoided. See "Toxic Soup" Below.


"Antibiotics do not work against viruses."

From research, Colloidal silver seems to have natural antibiotic properties against biological one cell germs AND viruses. It helps to boost the immune system and acts as a second defence against infections. The fact that it seems to have the ability to fight viruses made me look further because, as far as I am aware, antibiotics do not work against viruses. There does, however, seen the emergence of antiviral drugs such as Tamiflu, which are supposed to help against Influenza types A & B. See the FDA information here.

"Recent studies performed at the UCLA School of Medicine Center for Health Sciences confirmed that colloidal silver kills harmful bacterial, viral, and fungal organisms just minutes after contact."

Excerpt from the Journal of Longevity - Vol.4 / No. 10

Taken in small amounts, internally or externally, it is claimed to have a beneficial effect on many conditions. See dosage below & Uses.


"There's another virus going around!"

The simple answer is you don't actually need silver in your diet. Other minerals such as iron are essential but silver isn't necessary for the body to function. It's like an air bag in your car. You don't need it to drive but your are surely glad you have one when you need it! Silver has been known through the centuries for its healing properties. Due to our modern lifestyle, we do not ingest significant, if any, amounts of silver in our daily lives. Natural trace elements, including silver, have long since been depleted from the ground and hence from our diets. I don't know about you but I am always hearing people talking about new viruses and bugs going around and that they seem to be getting worse.

It seems logical that if silver has the properties it does, then the lack of it in our diets would have a serious & profound effect.

In the past, for the upper classes, most cutlery/serving utensils were made of solid silver and it would be ingested and entered the blood stream. This is where the term "Blue bloods" comes from which is actually the silver content in their blood. Although there are other factors why the upper classes lived longer such as the ate well, had better sanitation, kept warm and as a result, the will to live!

The disparity of longevity between the upper and lower classes was quite considerable. The "Not so fortunate" drank and ate from pewter which because of the high lead content, would often cause poisoning. More importantly, medical science is in a battle against viruses such as HIV, SARS and Global Viral threats. Thanks to Colloidal Silver, we may already have an effective preventative and I am relieved that I have a possible way of protecting my family.
"With the increasing depletion of nutrients in our soil, there is no simple way we can ensure that we get all we need from food."Ref. Dr. Atkins New Diet Revolution (2003) p 135

If you have a genetic family history of disease such as AIDS, Cancer, Chronic Fatigue Syndrome, Crohn's colitis, Type I diabetes, Multiple Sclerosis, Parkinson's disease, Wegener's disease, Rheumatoid Arthritis and Alzheimer's then you may wish to read this article. .

Many people use Colloidal Silver as a preventative, especially during winter. With closed cycle air conditioning, many offices, schools and work places are breeding grounds for various illnesses but taking just 5 ml daily can help provide a first level of defence. Having worked for years as a self employed IT Contractor, I know how much income I used to lose if I couldn't work. Since I have been taking Colloidal Silver, I haven't had any colds or flu. I do get the occasional sniffle but take 30 ml daily until it has gone. That to me, is remarkable.

Various claims for the treatment of the following conditions have been made, however these are only claims and we cannot validate them.

"Acne, allergies, appendicitis, arthritis, blood parasites, bubonic plague, burns (colloidal silver is one of the few treatments that can keep severe burn patients alive), cancer, cholera, conjunctivitis, diabetes, gonorrhoea, hay fever, herpes, leprosy, leukaemia, lupus, lymphagitis, lyme disease, malaria, meningitis, parasitic infections both viral and fungal, pneumonia, rheumatism, ringworm, scarlet fever, sinus infections, septic conditions of the eyes, ears, mouth and throat, shingles, skin cancer, staph infections, strep infections, syphilis, toxaemia, trench foot, all forms of viruses, including warts and stomach ulcers.

With the help from clients such as yourself, we are building and fine tuning the treatment guide in the "Uses" section of our site. Based on anecdotal evidence from real experiences, we can feed back this information to help you. We cannot make medical claims but we can feedback information from clients who have have experiences in its use and make this available to you and others.

Topical (External use) - Rashes, burns, skin conditions, thrush, insect bites etc. Apply Colloidal Silver on to the affected area twice daily using a compress or spray.

"Colloidal Silver is one of the few treatments that can keep severe burn patients alive"

In addition it also has veterinary uses, including canine parvo virus, kennel cough & cat flu. We have several clients who use it to prevent cross infections at "Shows" & Races and to keep them in top condition.

The medicinal/antibiotic/antiviral properties of silver have been know for centuries. It is only recently that modern research has formulated theories of how it actually works. In brief, it is to do with the particle size. From what I have read, I have gathered that the silver particles must be smaller than the virus/microbe/germ it is to fight. The electrolytic process is the only process I have seen that can produce particles of the correct size. Previously, silver salts or even powdered silver was used. This was probably the main cause of Argyria because the particle sizes are much larger in comparison.

We like to think that we make the best Colloidal Silver available on the market because we are the only manufacturer that has designed and built their own commercial generator(s), control the whole manufacturing process and make the product available for purchase. We spent over three years experimenting with different generator designs and the one we designed is far superior to any commercially available generator, for reasons that are listed in the next section.

More importantly, we have additional steps in our manufacturing process, to guarantee the final quality of the solution, which we believe is unique to us. We mature every batch produced, to ensure that it passes our quality checks. If a batch does not conform to the quality standards, we discard it.

Quality is very important to us. We want to inform the population of the benefits of Colloidal Silver & I believe you can only do this with a consistent quality product. See the Process section for a fuller explanation of the maturation cycle.

There are many Colloidal Silver sites in the UK advertising on the internet. We believe competition is a good thing but we also know that some of them are just resellers not specialists. That's not really a problem either or is it ? Over the years we have gained many customers who have changed suppliers, stating that our product quality was much better than their original supplier. Although that's good to hear, we wondered why. When we looked into it, there are many suppliers that buy their Colloidal Silver for the USA in PET plastic bottles. We have found PET is okay for short term use (Up to 2 months) but how long does it take to get an order from the USA and sell it in the UK ? We theorise that by the time the customer has received it, the shelf life has nearly expired! Whether this is true is debatable but makes sense to us.

We make our Colloidal Silver regularly and do not keep "Stock" as such. The longest we keep any stock, is over a weekend so that a batch made on Friday will be shipped on Monday.

We do, but it's our own design, not someone else's. Although there are some good commercial generators on the market, they all have at least two flaws, which is why we use our own design.

1 Most commercially available generators consist of an integrated unit containing an electrode assembly and a large plastic vessel with a tap at the bottom. After a production run, the solution is most likely bottled and shipped to the customer. As mentioned above, we have found that it takes several hours for the colloid to reach equilibrium (Mature) & its distinctive colour to develop. Only then can quality & stability be assured. We estimate 10% - 20% fails to mature and is discarded. What happens to theirs ?

2 The level of knowledge required to build a Colloidal Silver generator & understand the dynamics of the reaction is only at the Physics and Chemistry A-Level standard. Expertise in any manufacturing process is vitally important, especially to identify when things don't go according to plan. In my opinion, there is a high probability that owners of commercial generators have bought them because they lack the expertise to design and construct their own generator, which in turn suggests that they lack the expertise and understanding to ensure a safe, consistent quality product.

3 We manufacture & mature our Colloidal Silver in the dark, to help extend its shelf life. Commercially generators are generally too large and not designed to fit into light proof housings. Several of the designs I have seen are open to contamination from the open air where ours are covered throughout the process. These may be small points but we believe they are important.

There are many sites, especially in the USA where there are many examples of aggressive marketing, blatant inaccuracies & contradictory scientific statements. This only confirms to me that there are many people out there who really do not know what they are doing and are probably only interested in financial gain. This unfortunately, gives credibility to the legislation in the EU & US which is trying to regulate (Eliminate) sites such as ours, that are providing extensive information and a quality product.

Because its more environmentally friendly. Some suppliers state they are using dual and even triple pass distillation units. That means the water had been distilled two or three times, which is an incredible waste of energy. The reason we use a single pass system is because our natural Devon water is extremely soft to start with and that is all that it needs, which is why we are here in the first place. As the energy consumption for distilling the water is the highest energy use in the entire process, it makes sense to ensure that its used wisely.

We suggest that those who use a multi-pass distillation process are in hard water areas, consuming much more energy than necessary or are using it as "Marketing" to make you think their water is purer and therefore better. Unfortunately that is not really the case, as I have explained in the research section, as pure water doesn't conduct electricity, so if the water is too pure an additive will be required which is totally undesirable.

This section is in direct reply to a client, Jan , who read an article believed to be similar to this one here stating that silver should not be used because it is a heavy metal and will accumulate in the liver. After two days of research I cannot find any article that suggests this.

Why There is No Scientific of Medically Significant Basis to Classify Silver as a Heavy Metal See here

I conclude that the author of the article is using a "Silver scare" tactic, to differentiate themselves from other manufacturers to make their product seem better. NASA uses silver to recycle/purify water in the space shuttle & claim it is the purest water you can get. We know about lead, mercury, chromium (Hex) poisoning and I would be quite sure that if silver had the slightest health issue, we would know about it & we certainly wouldn't use silver for jewellery or utensils. True, some people have an allergic reaction to silver jewellery but that could be due to the use of sterling silver which has a high level of impurities (10%).

Churches use silver chalices to prevent transmission of infection when taking communion. The thought of sharing wine between dozens of people would be an ideal way of spreading an infection. I do not know of any incident where this has happened & I am quite sure the media would have picked up on any medical issues arising from it.

The US EPA (Environmental Protection Agency) state that the safe daily RFD (Reference Dose) is 5E10-3 or 50 ug daily.

See http://www.epa.gov/iris/subst/0099.htm for the full report.

There are certain sites out there that are trying to discredit EIS Colloidal Silver and are marketing Mild Silver Proteins or Colloidal Silver Proteins (MSP/CSP). I would certainly recommend you read the following page, which is my answer to the "Allegations" they have published. If you don't have time then you may be interested to know that two of the main characters involved are currently in a US jail & also, I suspect, were probably not listening in their chemistry lessons at school!

Minerals and vitamins found in the diet are excluded. Trace silver would be normally be found in the soil but modern farming techniques have depleted this natural source. This could be the reason we have so many modern viruses because each person is now a host for the virus to multiply, without the natural silver to protect us.

US EPA (IRIS) article extract (Source http://www.epa.gov/iris/subst/0099.htm )

Section I.A.4. Additional Studies/Comments (Oral RfD)

Humans are exposed to small amounts of silver from dietary sources. The oral intake of silver from a typical diet has been estimated to range from 27-88 ug/day (Hamilton and Minski, 1972/1973; Kehoe et al., 1940). Tipton et al. (1966) estimated a lesser intake of 10-20 ug/day in two subjects during a 30- day observation period.

With reference to the above article, I argue that we do not come under these regulations.

Many sites use PET plastic and some don't even use amber plastic. Although it may be okay for the short term, we believe it will degrade quickly. If they say their Colloidal Silver doesn't degrade then it is most likely they are selling you a purely ionic silver solution with no particulate silver content.

In Colloidal Silver, there are two silver components. One is ionic and the other is particulate. An ion is an atom that has gained or lost an electron. A silver atom has a single electron in its outer shell/orbit but when it loses it, becomes a silver ion with a +ve atomic (Ionic) charge. The particulate silver is a clump of metallic silver atoms that are not dissolved but are suspended in the colloid and has a small negative electrostatic charge called Zeta potential.

All electrostatic charges, by the laws of physics, tend to leak or discharge over time. This is known as dielectric leakage. There are many factors that cause this but the container, in our opinion, is vital. Glass is an excellent insulator but there again PET plastic is nearly as good. The main difference is that the walls of a PET bottle are much thinner than the equivalent glass by a factor of 5 to ten times. The rate of leakage is dependent on the dielectric constant of the material and the distance between the two charges or in this case the Zeta potential and "Earth" on the outside of the bottle. This is very similar to the theory of capacitors which is taught in GCSE Physics and probably most people can relate to this, if you were awake at the time !

Light also accelerate this process. The particulate silver in Colloidal Silver is in a fine balance between the repulsive forces of the Zeta potential and the attractive forces of the inter molecular (Van der Waals) forces. When this balance has been achieved the solution is in equilibrium. Light is made up of photons. Photons can knock electrons out of their orbits, as achieved in photo voltaic (Solar) cells but there are other consideration such as electromagnetic interaction. We've pasted an extract from Wikipedia below.

Electromagnetic interaction is a fundamental force of nature and is felt by charged leptons and quarks. Its exchange particle is the photon (symbol ·) and the many forms of electromagnetic radiation are a manifestation of this interaction.

Rutherford scattering showed that the electromagnetic field has a greater range than the weak or strong fields due to the photons having no mass, and travelling at the speed of light. The fact that photons have no mass makes them easy to produce, and charged particles usually interact electromagnetically before other fields have a chance to operate.

Electromagnetic interactions are long range attractions or repulsions between any particles or antiparticles that have charge. If the particles are attracted they stay together, because there is a continual exchange of photons.

What ever the mechanism, to preserve the delicate Zeta potential , the lack of stray photons must be desirable. In a completely ionic solution, this will not be a problem but then an ionic solution is just silver water and NOT a colloid & therefore not Colloidal Silver.

Also

There have been some recent media articles suggesting that certain chemicals can "Leach" out from the walls of a plastic container, contaminating the contents. Some research suggest that this is due to the porosity of the plastic and silver reacting with the plastic. Glass doesn't react, so it is the best medium for long term storage. Some PET manufacturers state that this problem is no longer the case, which indicates that it WAS a problem and we only have their word that it is no longer a problem.

The main reasons PET plastic is used are:-

  • Plastic is cheaper to purchase.
  • Its flexibility means less packaging is required to prevent breakages.
  • As it is significantly lighter, shipping costs are less.

We conclude that plasitc is used as it is cheap not the best. Unfortunately, it seems most are not passing on this saving in their prices !

We don't employ sales people. You are getting the final product straight from us, the manufacturer. We don't aim to be the cheapest. We aim for the best quality at the best price. We believe that most people realise that the best is never the cheapest.

We don't anymore. We have expanded our range to include smaller bottles of 200 ml, 50ml sprayers and 15 ml dropper bottles. We now supply starter kits for new clients with additional information that will not normally be given in an ordinary purchase.

There are several manufacturers that say they use 99.99% and even 99.999% silver. We have found that anything purer than 99.9% (Known as .999 fine silver) is quite difficult to obtain, very expensive and actually, unecessary.

Peter Lindemann has written an article and he shows that the quality of the water is more important than a slight increase in purity of the silver. See the section "Purity of Silver". The article is in Research section or click here.


"The bottom line is that higher concentration, for use in the body, is NOT desirable."www.silvermedicine.org


We sell 10 PPM for several reasons but the two main ones are listed below. As you may have read, Colloidal Silver is in a delicate balance of electrostatic charges and this balance is most stable at 10 PPM. The colour of a 10 PPM solution is also much more apparent and although we test and mature each batch, I can easily detect the quality just by looking at it. In fact, if the colour isn't right, I don't even test it - it goes straight down the sink.

Although extremely rare, Argyria is something to avoid. The smallest every day quantity that we tend to use is the humble teaspoon. I wanted to ensure that the dose my family and I take is based on this common measure. From my research (See below) I have concluded that 1 teaspoon of 10 ppm Colloidal Silver equates to 50 micro grams of silver which is exactly the nutritional amount suggested. Some sites sell 30 ppm or 100 ppm. How do you measure 1/3 or 10th of a teaspoon? In everyday life, we would probably take more than we need if the concentration was higher. My opinion is that it is unsafe to sell Colloidal Silver at high concentrations. See Argyria and Stan Jones below.
"However, with most available production methods, a higher concentration yields a lower quality end product. The result is an unstable solution with large particles."

The size of the silver particles is more important than the concentration (PPM). The particles must be in the range of 0.001 to 0.04 microns otherwise they will be ineffective. You wouldn't ask for a box of 20 bolts, you would specify the size. A Colloidal Silver solution of 20 PPM but has a particle size over .04 microns will be ineffective but you would be mislead into thinking it was twice as strong. Silvermedicine.org state that it is not possible to make Colloidal Silver over 25-26 PPM without using additives. In my opinion additives are totally undesirable as this could lead to Argyria.

There are two basic forces in action in a Colloidal Silver solution. Firstly there is the negative charge on the silver particles which repel each other but there is also the Van der Waals "Inter molecular" force which is attracting them. The repelling force is a function of the distance between the particles and behaves as an inverse square law where the force increases 4 time if the distance between the particles is halved. I theorise that in higher concentrations of Colloidal Silver, as there are more particles per unit volume, the forces are higher and the particles attract, agglomerating (Combining together) to produce larger particles. This will continue until the distance between the particles is sufficient for the forces to be in balance again but you have ended up with larger particles. If the particles become too large they will be ineffective. So a lower PPM is actually better ! Strange but true. As the particle size is more important, we label our product accordingly stating the particle size first and then the manufactured PPM. All Colloidal Silver solutions will agglomerate to some extent until the solution has attained equilibrium.

That is why we mature our Colloidal Silver to ensure it is stable. As it matures, the PPM will reduce slightly and the particle size will increase. As long as the final size is within .001 to .04 microns, it is effective. There are many factors that determine the final size including voltage/current field strength between the electrodes.

There are also external factors such as ambient temperatures local RF emissions and even factors such as the Earth's magnetic field. We constantly have to monitor and alter the final current and find we have to reduce it in the summer months when ambient temperatures are higher. Remember the difference between the sizes of .04 and .001 is a factor of forty but this is only the diameter of the particles NOT the volume. The volume is much greater than this.

"Two teaspoons of 5 ppm colloidal silver provides about 50 mcg of silver and could be considered a "nutritional" amount, if taken on a daily basis. Any amount above four teaspoons a day or 100 mcg should be considered a "therapeutic" amount. That said, it should not be assumed that electro-colloidal silver is equivalent to or has the same metabolic effect as receiving trace silver from dietary plant sources. But since there are very few plant sources of trace silver available today, colloidal silver is probably the best substitute. If you want to experiment with taking colloidal silver for an extended period of time, stay within the amounts considered to be nutritional. If you want to experiment with larger doses, do so with caution, and only for a day or two at a time."Excerpt from "A Closer Look At Colloidal Silver" By Peter A. Lindemann,

It would suggest that from the above one teaspoon (5ml) of 10ppm Colloidal Silver is a nutritional amount.

"The EPA has indicated that there is no known risk associated for an average adult to consume up to 7 teaspoons daily of 10 ppm for 70 years when manufactured according to the above attributes. For therapeutic purposes, doctors may use this as a general guideline to escalate dosages over a shorter time period. As a dietary supplement, the safety parameters of this product description serves a wide spectrum of patient populations. For example, this same EPA guideline would permit 14 teaspoons to be consumed daily for up to 35 years. Or, a doctor may even wish to utilize graduated dosages, and over time suggest that their patients take under supervision up to 7 Tablespoons daily. Due to the silver's purity, these recommendations should advise the patient to always take the product on an empty stomach, which may then be followed by food 25 minutes later."

Conclusion from article http://www.silvermedicine.org/colloidalsilveruniversal.html

This all depends on your diet and your general well being.

The body utilises selenium to help eliminate silver from the body-- Silver bonds with selenium. When the body is depleted of selenium, the amount of silver deposited into tissues is drastically increased. This was conclusively demonstrated by a researcher known as Petering in the 1970's. http://www.silvermedicine.org/argyria.html

In the event that greater doses are required for long term treatments, dietary measures to augment the body's elimination system are likely a good idea, including Selenium and Vitamin E supplementation and proper hydration of the body. http://www.silvermedicine.org/safety.html

Both Selenium and Vitamin E are known to be excellent antioxidants used to reduce and eliminate free radicals from the body. Selenium seems to be important in the mechanism of removing excess silver from the body. If you feel you could be lacking in Selenium and Vitamin E we would certainly recommend a supplement.

We can supply an Antioxidant pack with Selenium and a Daily nutritional supplement - See the ORDER pages.

This is covered in depth in the Research section.

From our extensive research, we have discovered there are many good & bad practices and we have included the following in our own procedures. See Process for more information.

  1. We use steam distilled water ONLY. We have our own units to do this. We never use deionised/mineral/purified/filtered water, just good steam distilled water.
  2. We never use saline solution to speed up the reaction. In fact NO additives are used before, during or after the process. We feel that additives are dangerous and could contribute to the condition of Argyria by forming unwanted silver salts.
  3. We use .999 silver electrodes. We never use anything less pure.
  4. The generators are designed and built by us & not commercially available.
  5. During the whole process, we use only laboratory grade borosilicate glass. We use glass reaction vessels, glass funnels and glass measuring beakers & glass bottles. Many commercial generators use plastic vessels. Although I am not completely against the use of plastic, I feel the use of plastic should be limited. Glass is natural, plastic is man made.
  6. We make Colloidal Silver in the dark in 3 litre batches. Each bottle is dated & tracked to the batch made.
  7. Most importantly - we mature every batch made to ensure quality. We throw away the rest.
  8. We use light secure glass Amber Medical bottles with child proof caps.

The honest answer is yes but from my research I have found that it is very easy to make bad colloidal silver and quite difficult to make good Colloidal Silver.

Quality is very important and there is a wealth of advice available, most of it conflicting. Some sites say the solution should be brown. Some say anything less than 500ppm is a waste of time and money -That's because they are selling you Mild Silver Protein which can lead to Argyria.

I also found the most difficult aspect is obtaining steam distilled water, as most water is deionised these days. As mentioned above, we have invested in our own steam distillation units because our research has shown that this is the best. We also use Electronic Stabilised Power Supply Units with current limiting, so we can adjust the voltage & current levels accurately. Our original research test generator MK1 used batteries. It worked well for the first 3-4 batches but as the voltage dropped, the final product was found to be unstable & inferior. This was due to the change in particle size.

I have found that my technical background is essential to know when something isn't quite right. It has also helped me in my research and helped identify many sites who, in my opinion, recommend quite unsafe practices.

What's the most dangerous part of a car? Its the nut behind the steering wheel! There are many reason why we don't sell generators, especially our design. There are commercial generators available for purchase but I have found it is imperative that anyone who makes Colloidal Silver is qualified to do so. With any manufacturing process, quality assurance can only be implemented by personnel who know what they are doing.

Although the process seems fairly simple, the dynamics of the reaction are quite complex and understanding when the process isn't working is very important. Without knowledge and training, its very easy to make bad colloidal silver.

In addition to having the right equipment, steam distilled water is very difficult to obtain. This is why certain generator manufacturers recommend additives. This is completely wrong advice.

I did consider putting a kit together, including the steam distillation unit but it would have to retail for around £2,500 because of the cost of the distillation & the high degree of training required.

In the end, we do not sell or intend to sell generators and I feel that although there are some good generators, they are sold to people who have little or no understanding. This may be fine for your own self-use but not for commercial sale, unless quality can be guaranteed.

This depends on the concentration of the final colloid. The Colloidal Silver should be clear with a yellow/golden tinge. The colour only appears with concentrations over 5 PPM. It is easy to see this colour in large vessels but is less obvious in small quantities. See PROCESS section for pictures. The colour is caused by light scattering :

"Nanoparticles often have unexpected visible properties because they are small enough to scatter visible light rather than absorb it. For example gold nanoparticles appear deep red to black in solution." Wikipedia

All silver products are susceptible to oxidation from light, temperature and exposure to air. The cooler and more shaded the storage, the longer it will keep. We used to keep ours in the fridge but this is unnecessary and normal ambient room temperature is fine. In theory, it could last for years but I recommend 3-9 months depending on the conditions above.

Note:- If your colloidal silver has turned grey, don't use it because it has oxidised.

I don't think we would last very long as a business if we did, although its a good question & one which we have been asked several times. Firstly, I hope the information on this site is useful to you and I'm certain nobody would go to this much trouble if they were trying to just sell you water!
