Unregulated nutritional supplements containing desiccated thyroid can cause hyperthyroidism. Patients taking these products may consume dangerous doses, leading to adverse health effects.

Area of Science:

  • Endocrinology
  • Pharmacology
  • Public Health

Background:

  • Nutritional supplements are largely unregulated by the Food and Drug Administration (FDA).
  • These products can contain various ingredients, including animal tissues like desiccated thyroid.
  • Desiccated thyroid is sometimes marketed in nutritional supplements without proper oversight.

Observation:

  • A patient presented with symptoms including resting tachycardia, amenorrhea, and weight loss.
  • The patient reported taking a nutritional supplement containing desiccated thyroid for three months.
  • Her laboratory results confirmed the presence of hyperthyroidism.

Findings:

  • The patient's consumed dose of desiccated thyroid exceeded the normal replacement dose by two to three times.

  • The supplement contained unregulated desiccated porcine or bovine thyroid.
  • This led to iatrogenic hyperthyroidism.

    • Implications:

    • The unregulated availability of desiccated thyroid in supplements poses a significant risk to public health.
    • Healthcare providers should inquire about supplement use in patients with unexplained thyroid dysfunction.
    • Stricter regulation of the supplement industry is warranted to prevent harm.
