Product Description

Each capsule delivers 225 mcg iodine (as potassium iodide + iodine), 3 mg L-tyrosine, and 56 mcg selenomethionine. Capsules are gluten-, soy-, and dairy-free.

What We Like

  • Combines the key thyroid building blocks in one capsule
  • Low tyrosine amount reduces headache risk
  • NSF-certified manufacturing

What We’re Missing

  • No vitamin A or zinc despite their relevance to thyroid function
  • 225 mcg may be too much for high seaweed consumers

Usage Recommendation

1 capsule in the morning with a small amount of fat-containing food. Use with Hashimoto’s only after consulting a doctor.
