Vitamins & Supplements for Thyroid Health

Learn about vitamins and supplements that research suggests may support thyroid function. Always consult your healthcare provider before starting any supplement.

Important: Consult Your Doctor First

Supplements can interact with thyroid medications and other treatments. Always talk to your healthcare provider before starting any new supplement, especially if you're taking thyroid medication like levothyroxine. Some supplements should be taken hours apart from thyroid medication.

Commonly Recommended Supplements

The following supplements are often discussed in relation to thyroid health. Research varies, and individual needs differ.

Selenium

An essential mineral that plays a role in thyroid hormone metabolism. The thyroid gland contains high concentrations of selenium.

Zinc

Required for thyroid hormone synthesis and metabolism. Zinc deficiency may impair thyroid function.

Potential Benefits:

Vitamin B12

Commonly deficient in hypothyroidism. B12 is crucial for energy production and neurological function.

Potential Benefits:

  • May help reduce fatigue
  • Supports nervous system health
  • Important for red blood cell formation

Iron

Essential for thyroid hormone production. Iron deficiency can worsen hypothyroidism symptoms.

Potential Benefits:

  • Required for thyroid hormone synthesis

Note: Take iron supplements several hours apart from thyroid medication.

Iodine

Essential for thyroid hormone production, but supplementation is controversial. Most people get enough from diet.

Important Considerations

Timing with Thyroid Medication

If you take thyroid medication (like levothyroxine), certain supplements should be taken at least 4 hours apart to avoid absorption issues:

  • Iron supplements
  • Calcium supplements
  • Antacids containing aluminum or magnesium

Always take your thyroid medication on an empty stomach, typically first thing in the morning, and wait at least 30-60 minutes before eating or taking other supplements.
