What is a Dietary Supplement?
  • Definition (Sec 3.)
  • A product (other than tobacco) intended to
    supplement the diet that bears or contains one or
    more of the following dietary ingredients
  • Vitamins
  • Minerals
  • Herbs or other botanicals
  • Amino acids
  • Concentrate, metabolite, constituent, extract or
    combination of above listed ingredients

Dietary Supplements
  • Traditionally defined as products made of one or
    more essential nutrients such as vitamins,
    minerals, and proteins, but
  • DSHEA broadened definition to include almost any
    product intended for ingestion as a supplement to
    the diet
  • Must be identified on label as a D/S

Dietary Supplements
  • Distinguished from Drugs
  • Drug article intended to diagnose, cure,
    mitigate, treat, or prevent disease
  • Both intended to affect structure and function of
  • Drug must undergo FDA approval after clinical
    studies to determine effectiveness and safety
  • D/S no pre-market testing

Dietary Supplements
  • Distinguished from Foods
  • Foods not intended to affect structure and
  • D/S intended only to supplement diet
  • Not represented for use as conventional food
  • Not intended as sole item of a meal or the diet

Dietary Supplements
  • No premarket approval
  • Manufacturer responsible for safety evaluation
  • If D/S contains a new ingredient
  • Manufacturer must submit information that
    ingredient can reasonably be expected to be
    safe within 75 days of marketing
  • Safe no significant risk of illness

Adulteration under DSHEA
  • D/S is adulterated if it or an ingredient
    presents significant or unreasonable risk of
    illness or injury when used as directed
  • If contains a new ingredient standard is
    insufficient information to provide assurance
    that ingredient does not present.
  • FDA has burden of proving D/S is unsafe once
    product is marketed

  • (significant or unreasonable risk of injury)

FDA Enforcement Authority
  • FDA bears Burden of Proof
  • Must prove that product is unsafe
  • DSHEA requires de novo (fresh look)
    determination for each case
  • No longer presumes FDA is correct on science
  • FDA must provide 10 days notice before initiating
    civil proceeding
  • Only required in criminal case before DSHEA
  • Whose idea was this!!!!!!!!!!!

Good Manufacturing Practices
