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 sets this vitamin B3 product apart from others?
Our vitamin B3 contains a high-strength 500 mg of niacin in pure nicotinamide form. It is lab-tested in Germany, free from additives and suitable for vegans.
Is the product really vegan and free from additives?
Yes, our capsules are 100% vegan. The shell is made of plant-based cellulose, and we deliberately do without sugar, colourings, flavourings or sweeteners. Purity and natural ingredients come first for us.
How long does a pack last and how do I take it?
One pack contains 90 capsules, which is enough for 90 days. Taking it is simple: 1 capsule daily with sufficient liquid.
Are there side effects, and is the high dose safe?
If you keep to the recommended use, no side effects are expected. Our 500 mg corresponds to 3,125% of the NRV (daily requirement), which makes sense in particular for people with an increased requirement. If you are unsure, we recommend speaking to a doctor.
How do I know the product is safe?
We produce to strict quality standards (GMP). Every batch is tested extensively for purity to make sure it is free from heavy metals or contaminants.
