Dietary Supplements

Artificial supplementation ensures a population has sufficient access to essential nutrients

  • Supplements may be added to natural dietary sources or taken independently with meals (e.g. vitamin tablets)
  • The cost to supplement dietary products is minimal compared to the cost of treating deficiency diseases

Examples of dietary supplementation include:

  • Production of iodised salt to prevent iodine deficiencies like goitre (iodine is important for thyroxine production)
  • Fluoridation of water supplies to protect teeth against decay (fluorine is important in tooth development)
