Dragons' Den investor Tej Lalvani is chief executive of the vitamin company Vitabiotics. The business was founded by his father, Kartar Lalvani, and Tej became involved in its management before joining the BBC investment show.
Vitabiotics develops and markets nutritional supplements, including the well-known Wellman and Wellwoman ranges. Its products are sold in many countries, making the company a major part of Lalvani's business background.
Vitabiotics is a company name, whereas Wellman and Wellwoman are product ranges. That distinction explains why quiz answers sometimes incorrectly name one of the brands instead of the company led by Lalvani.
