Harald Pfeffer, MD
Inspired by his rescue as a child, Harald Pfeffer dedicated himself to medicine. In 1976, he opened his own practice, which he handed over in 2003 to remain true to his vision "Health belongs in the world, not within four walls". With Vitabay, this vision became reality. All our products meet the standards of a medical device and are the result of over half a century of medical knowledge, research, and development. With his own patents, products, and formulas, he shapes not only Vitabay but the entire supplement industry.
