NCCN recommendations are as follows:

  • Supplement use is not recommended for most survivors except in instances of documented deficiencies, inadequate diet, or comorbid indications (eg, osteoporosis, ophthalmologic disorders, cirrhosis)

  • Providers should assess supplement use at regular intervals and ask about reasons for supplement use and supplement ingredients

  • Survivors of certain cancers (eg, gastric cancer) are at risk for vitamin deficiencies based on their cancer treatment; in these patients, deficiencies should be assessed and addressed as needed
