Dr. med. Harald Pfeffer
Inspired by his rescue as a child, Harald Pfeffer committed himself to medicine. In 1976 he opened his own practice, which he handed over in 2003 to stay true to his vision "health belongs in the world, not within four walls". With Vitabay, that vision became reality. All our products are the result of more than half a century of medical knowledge, research and development. With his own patents, products and formulas he shapes not only Vitabay but the whole supplement sector.
FAQ
What makes your colloidal silver different from other products?
Our ionic colloidal silver is produced by modern electrolysis to give a particularly fine silver structure with high purity. Every batch is checked closely for consistent quality. We also do without artificial additions and stabilisers and use light-protected packaging to preserve purity and stability.
Is the product really free from additives?
Yes, our ionic colloidal silver contains only pure, demineralised water and silver particles, with no preservatives, stabilisers or other additions. We aim for high purity and have every batch tested in the laboratory.
How long does the bottle last and how do I dose it correctly?
How long it lasts depends on your individual use. As this is a concentrated product, a small amount is enough. A precise recommendation for use should be determined individually.
How should I store the product so the quality is preserved?
The silver should be stored in a cool, dry and light-protected place, ideally in a cupboard or a closed drawer. Direct sunlight and extreme temperatures can affect its stability.
Why is the packaging light-protected?
Silver particles react sensitively to light, which is why we deliberately chose opaque packaging. This protects the quality of the product and gives it a longer shelf life without the need for artificial stabilisers.
Where is the product made and which quality standards apply?
Our colloidal silver is lab-tested in Germany. Every batch goes through laboratory checks for consistent quality.
