FAQ
What differentiates your colloidal silver from other products?
Our ionic colloidal silver is produced using state-of-the-art electrolysis to ensure a particularly fine silver structure with high purity. Each batch is rigorously tested to guarantee consistent quality. Additionally, we avoid artificial additives or stabilizers and use light-protected packaging to preserve its purity and stability.
Is the product truly free of additives?
Yes, our ionic colloidal silver contains only pure, demineralized water and silver particles – no preservatives, stabilizers, or other additives. We prioritize the highest purity and have every batch laboratory-tested.
How long does the bottle last and how do I dose it correctly?
The longevity depends on individual use. As it is a highly concentrated product, a small dosage is sufficient. Precise dosage recommendations should be determined individually.
How should I store the product to maintain its quality?
The silver should be stored in a cool, dry, and dark place, preferably in a cabinet or closed drawer. Direct sunlight and extreme temperatures can affect its stability.
Why is the packaging light-protected?
Silver particles are sensitive to light, which is why we deliberately chose opaque packaging. This protects the product's quality and ensures a longer shelf life without the need for artificial stabilizers.
Where is the product manufactured and what quality standards apply?
Our colloidal silver is manufactured in Germany under strict quality and purity standards. Each batch undergoes laboratory controls to ensure consistently high quality.
