2026 search trend

Total kelp milligrams are not the same as micrograms of iodine. Thyroid blends may also list iodine across more than one source.

What to compare on product labels

• Confirm whether the unit is mcg or mg.
• Separate potassium iodide or kelp source weight from the actual iodine supplied.
• Add iodine from multivitamin, prenatal, and thyroid-support products.
