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.
