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.
FAQ
Is the product really vegan?
Yes, our Vitamin D3 is derived from lichen, a plant-based source, and both Vitamin K2 and all other ingredients are purely plant-based. The product is completely free from animal ingredients and was specially developed for a vegan diet.
What exactly does "depot formula" mean?
The depot formula means that you only need to take one tablet every 10 days, as the nutrients are dosed in such a way that they can be utilized by the body over a longer period. This makes application particularly convenient.
Are there any side effects if I take this product?
Side effects are very unlikely at the recommended dosage. If you are taking blood-thinning medication or have other health concerns, we recommend consulting your doctor before taking it.
How long does the product last?
The product contains 180 tablets and, when taken every 10 days, lasts for a full 1800 days – that's almost 5 years! A particularly sustainable solution.
Is the product also suitable for older people?
Absolutely. The combination of Vitamin D3 and K2 supports the maintenance of normal bones and is therefore particularly important for older people, whose vitamin D levels are often lower. In addition, the depot formula makes taking it especially convenient.
