When everyday support isn't enough, go Extra Strength. Silver Biotics® Extra Strength Immune Support delivers 30 PPM of our patented SilverSol® nano silver — three times the concentration of our standard formula — for those moments when your immune system needs maximum, targeted reinforcement.
The science behind 30 PPM SilverSol®
Concentration matters when it comes to silver supplementation. Our Extra Strength formula uses the same patented SilverSol® nano silver technology trusted by millions, amplified to 30 PPM for a more potent daily dose. Each nano silver particle is engineered to a precise size and frequency that maximizes bioavailability while remaining safe for regular use — no argyria risk, no heavy metal buildup.
When to choose Extra Strength
Extra Strength is the go-to choice during seasonal challenges, high-stress periods, travel, or anytime your body is working harder than usual. Many customers use it alongside our standard 10 PPM formula — daily maintenance with the standard, and Extra Strength as a targeted boost when needed.
