Optivida Nano Silver Liquid 10 PPM | 16 oz
Every fall, it starts again
According to the CDC, the average American adult catches two to three colds a year, and kids often catch more. Colds are one of the most common reasons people miss school and work.
So every fall, the shelves fill up with immune products. Turn them around and you'll find long labels: sugar, syrups, flavors, dyes, sometimes alcohol.
Optivida Nano Silver has two ingredients: silver and deionized water, measured at 10 PPM. One clear, tasteless teaspoon a day to support your immune system.*
So what if your daily immune support* came with nothing else?
Children often have more.

What's in the bottle
Ultra-small, uniform silver particles suspended in deionized water at a measured 10 PPM. Clear, tasteless and easy to take straight from the spoon, for daily immune support.*
A teaspoon a day to support your body's natural defenses through school, travel and seasonal change.*
No alcohol, dyes, fragrance, sugar or preservatives. Clear and tasteless.
10 PPM and 50 mcg per teaspoon, printed right on the label.
Adults and kids each have their own serving on the label.
Let's talk about the label
Two questions come up more than any others. We'd rather answer them up front.
A colloid is simply tiny particles spread evenly through a liquid. Milk is a colloid. So is fog. Nano Silver is ultra-small silver particles suspended in deionized water, so "colloidal" is technically accurate.
It's also the word most people search for, which is why Optivida put it on the front of the bottle. The formula didn't change.
Not when it's used as directed. The blue-skin stories online come from people making silver at home at unknown, extreme strengths and drinking it in large amounts every day for years. That has nothing in common with a measured product taken by the teaspoon.
The EPA set its lifetime daily limit for silver specifically to protect against skin discoloration. Even at the label's maximum of 3 teaspoons a day (150 mcg), a 150-lb adult stays under half of that limit (about 340 mcg), every day, for a lifetime.

Thousands of years of silver
Greeks, Romans and Persian kings stored water and wine in silver to keep it fresh on long journeys.
Settlers dropped silver coins into milk and water barrels, a habit passed down for generations.
Doctors began using silver drops in newborns' eyes, a practice that lasted for decades.
Silver preparations were common in medicine cabinets until penicillin arrived in the 1940s.
Silver is built into modern wound dressings, and the Russian side of the International Space Station uses silver to treat drinking water.
Optivida's Nano Silver uses ultra-small, uniform particles at a measured, low concentration. Old tradition, modern precision.
Is it safe? We checked.
Researchers at the University of Utah had 60 healthy men and women, ages 18 to 80, take nano silver by mouth every day for up to two weeks. Before and after, doctors ran the same tests you'd get at a checkup, and then some.
The honest fine print: it was a short study in healthy adults. It shows no signs of harm over that time, and we won't claim more than that.

The EPA publishes how much silver an adult can take in every day for a lifetime. Even at the most the label allows (3 teaspoons a day), a 150-lb adult uses less than half of that limit.

No. Only the wording on the front of the bottle changed. The ingredients, concentration and manufacturer are the same.
Adults: 1 teaspoon up to 3 times a day. Children: 1/4 to 1/2 teaspoon once a day. That's straight from the label.
Like water. It's clear and tasteless, with nothing added for flavor.
