About Nature’s Sunshine Silver Shield w/Aqua Sol
Your immune system works around the clock to protect your body from environmental challenges. Nature’s Sunshine Silver Shield w/Aqua Sol provides broad-spectrum immune support using advanced silver technology that has been trusted for generations. This liquid dietary supplement combines the time-honored benefits of silver with cutting-edge Aqua Sol Technology to deliver superior bioavailability and effectiveness.
What makes Silver Shield truly exceptional is its patented manufacturing process that creates unique nano-sized silver particles. Unlike conventional ionic or colloidal silver products that may contain larger particles with limited bioavailability, Silver Shield features precisely engineered nano-particles that are 99% bioavailable. Each teaspoon provides 100 mcg of pure silver at 20 parts per million (ppm), suspended in deionized water for optimal absorption.
Advanced Aqua Sol Technology
The secret behind Silver Shield’s effectiveness lies in its patented Aqua Sol Technology. This innovative process creates silver nano-particles with a unique dual structure featuring an interior of elemental silver and an exterior coating of ionic silver in the form of silver oxide. This sophisticated design allows the silver particles to work more efficiently than traditional silver products, delivering maximum benefit with lower concentrations.
Research shows that silver nano-particles can anchor to bacterial cell walls and infiltrate them, causing physical changes that are harmful to unwanted microorganisms. The dual-action design of Silver Shield’s particles makes this process even more effective, which is why our 20 ppm formula often outperforms products with much higher concentrations.
Safety and Purity You Can Trust
Safety is paramount when choosing a silver supplement. Silver Shield is completely non-toxic and poses no risk of heavy metal contamination or the blue skin discoloration (argyria) sometimes associated with inferior silver products. The nano-particles are processed through the kidneys and do not accumulate in the body or affect beneficial bacterial populations in the digestive system.
Nature’s Sunshine follows strict quality control standards to verify the potency and purity of every batch. The result is a safe, effective product that you can use with confidence. The clear, tasteless, and odorless liquid makes it easy to incorporate into your daily wellness routine.
A Legacy of Silver in Health
The use of silver for health purposes has ancient roots. Historical records show that people in Asia and the Mediterranean region, including the Roman Empire, used silver drinking vessels and storage containers to keep liquids fresh. American pioneers placed silver dollars in milk jugs to prevent spoilage during long journeys across the plains.
Hippocrates, known as the Father of Medicine, documented the use of silver for wound care over 2,000 years ago. Today, silver continues to be valued in modern medicine, appearing in wound dressings, bandages, and medical device coatings to help reduce infection risk.
Convenient Size Options
Silver Shield w/Aqua Sol is available in four convenient sizes to meet different needs and preferences. The 4 oz size is perfect for travel or trying the product for the first time. The 6 oz and 16 oz bottles are ideal for regular daily use, while the 32 oz size provides excellent value for families or those who use the product consistently.
Recommended Usage
Take one teaspoon, swish and swallow, three times daily. Do not mix with salt or salty liquids. For oral use only. Not recommended for long-term use. Keep out of the reach of children.
Frequently Asked Questions
Silver Shield uses patented Aqua Sol Technology to create nano-sized particles with dual structure – elemental silver interior and ionic silver oxide exterior. This design provides 99% bioavailability and superior effectiveness at just 20 ppm, often outperforming products with much higher concentrations.
Silver Shield is non-toxic and safe when used as directed. However, the label states it’s not recommended for long-term use. The nano-particles are processed by the kidneys and don’t accumulate in the body or cause skin discoloration like some silver products can.
While Silver Shield is generally well-tolerated, it’s important to consult with your healthcare provider before combining it with medications or other supplements, especially if you have health conditions or take prescription drugs.
Salt can interfere with the stability and effectiveness of the silver nano-particles. The ionic content in salty substances may cause the silver particles to clump together, reducing their bioavailability and effectiveness.
The 4 oz size is great for travel or first-time use, 6 oz and 16 oz are perfect for regular daily use, and the 32 oz size offers the best value for families or consistent users. Each teaspoon provides the same 100 mcg of silver regardless of bottle size.
