Why Nano Silver
Most wellness products come with a long ingredient list. This one has two. It's for people who want to support their immune system* without adding sugar, alcohol, dyes or fillers to their day.
A teaspoon a day to support your body's natural defenses through school, travel and seasonal change.*
Silver and deionized water. No alcohol, dyes, fragrance, sugar or preservatives. Clear and tasteless.
10 PPM, 50 mcg per teaspoon, printed on the label. Made in the USA for Optivida in Orem, Utah.
Let's talk about the label
You've probably seen the scary stories about silver. We'd rather answer them up front than hope you don't ask.
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 you've seen 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.
Nano Silver is measured at 10 PPM: 50 mcg per 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
Silver isn't a trend. It's one of the oldest wellness traditions on record, and it's still used in hospitals today.
Ancient world
Greeks, Romans and Persian kings stored water and wine in silver to keep it fresh on long journeys.
Pioneer era
Settlers dropped silver coins into milk and water barrels, a habit passed down for generations.
1880s
Doctors began using silver drops in newborns' eyes, a practice that lasted for decades.
1900s
Silver preparations were common in medicine cabinets until penicillin arrived in the 1940s.
Today
Silver is built into modern wound dressings, and the Russian side of the International Space Station uses silver to treat drinking water.
Now
Optivida's Nano Silver uses ultra-small, uniform particles at a measured, low concentration. Old tradition, modern precision.
How to use it
Clear and tasteless, so it's easy to take straight from the spoon. Directions are straight from the label.
1 teaspoon, up to 3 times a day.
1/4 to 1/2 teaspoon, once a day.
Same time every day, like with breakfast. Consistency matters more than amount.
Daily
Part of your everyday routine as the seasons change.*
When you feel run down
The label suggests starting at the first sign you're feeling off.*
Dropper or mist
Fill a dropper or fine-mist bottle from the Applicator Kit below.
On the go
Bring it along for trips, school weeks and busy schedules.
Is it safe? We checked.
You want something simple: silver and water, not another product full of lab-made chemicals from a giant corporation. Fair enough. You also want to know it's safe. So do we.
The study, in plain English
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. It doesn't prove anything beyond that, and we won't pretend it does.

Think of it like a speed limit
The EPA, the government agency that sets safety limits, 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.

Questions
No. Homemade silver is made with no way to measure strength or particle size. Nano Silver is manufactured in the USA to a measured 10 PPM, with the dose per teaspoon printed on the label.
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.
