Shelf Life of Colloidal Silver

What is the shelf life of colloidal silver?

How long will colloidal silver last if stored properly? What is the best way to store it? The shelf life of colloidal silver has been proven to last over 10 years when stored correctly! This is dependent on meeting the proper storage conditions. Mountain Well-Being Colloidal Silver comes with a guaranteed shelf life of three years.

What are the proper conditions to maximize shelf life of colloidal silver?

It’s simple, to correctly store colloidal silver to last as long as you need, there are three key factors to keep in mind.

  1. Store colloidal silver at room temperature. Extreme temperatures can shorten the shelf life.
  2. Keep colloidal silver out of direct light and store it in amber or cobalt colored glass containers. Plastic containers will definitely shorten the shelf life.
  3. Keep colloidal silver away from strong electromagnetic frequencies, such as appliances or computers. Each silver ion and particle have an electric charge that keeps them colloidal (or suspended) in the liquid. They can lose their charge more quickly when exposed to strong electromagnetic fields.

A kitchen cupboard or a bathroom medicine cabinet is an ideal spot to keep your bottle of colloidal silver. But honestly, I keep a bottle in my bathroom, kitchen, truck, next to my bed, and in my Camelbak for when I’m on the trail. As long as the conditions above are met, it really doesn’t matter where you keep it.

Where and how do you store your colloidal silver?

    So… if I kept mine in the refrigerator the shelf life might be diminished? It was recommended to me to extend the shelf life…

      Hello Tascha,
      For the longest possible shelf life (10 years+), it’s best to store colloids at room temperature. If you’ve put yours in the refrigerator for a short time, there should be no problem.
      Be well,

    How about opened bottles? I use colloidal silver for sinus/cold issues. If the seal is broken and you don’t use all off the bottle. What is the shelf life then if it’s stored properly?

      Hello Frank,
      As long as you pour out of the bottle and replace the cap immediately, the shelf life should be the same. Make sure you don’t touch your lips to the bottle, and no foreign contaminants get into the bottle. Are you using colloidal silver both internally and in the sinuses? That’s what I’d recommend for sinus issues. Our newest product, Sulfur Silver Sinus Spray, works great if you haven’t tried it yet. You can find it here:
      Be well,

        I just use it internal but I will look into the spray. Thanks for your quick response. Take care

    How effective is colloidal silver as a mouth wash for mouth ulcers? How long should it take for the ulcer to go?

      Hello Peter,
      We are not allowed to make any medical claims, but if it were me, I’d swish with colloidal silver at least several times per day. The longer you can swish with it in your mouth, the better.
      Be well,
