Former Visiting Professor Patrick Holford is Head of Science and Education at Biocare so he has a substantial and understandable interest in selling supplements. Creating a large-scale market for supplements depends upon several factors. The factors include convincing people that:
- they have clinical or ‘sub-clinical’ vitamin or mineral deficiencies
- the food that is commonly available and forms their regular diet is deficient in vitamins, minerals and other micro-nutrients
- there is good evidence that supplements improve health or are adequate prophylactics.
