About this product

The formula supplies 1,500 mcg from potassium iodide in a 90-capsule supply. A reliable form in a longer-use package, but the amount exceeds the adult upper intake level despite convenient packaging.

Iodine supports normal thyroid-hormone production when intake is inadequate. A high dose does not provide broader energy, metabolism, or hair support and may instead destabilize thyroid control.

Routine self-directed use is therefore hard to justify. The format may be convenient, yet the exposure calls for a defined clinical reason and thyroid monitoring.

Who is it for
  • people with a documented need and ongoing clinical monitoring
  • people whose diet provides too little iodine
Best for
  • targeted iodine support
  • supporting normal thyroid-hormone production when iodine intake is low

Pros

  • Clearly states an iodine amount of 1,500 mcg
  • A reliable form in a longer-use package
  • 90-capsule supply keeps use straightforward

Cons

  • The amount exceeds the adult upper intake level despite convenient packaging
  • Poor fit for ordinary daily maintenance
  • Does not provide broader support for the listed goals

Warnings

  • The 1,500 mcg serving calls for direct medical oversight because it exceeds routine nutritional intake.
  • Do not combine this dose with kelp, multivitamins, or other iodine supplements.
  • People with autoimmune thyroid disease, thyroid nodules, or thyroid-medicine use are especially vulnerable to thyroid disruption from high iodine.

Product analysis

64 out of 100
The formula is clearly positioned for high-potency iodine, but the amount exceeds the adult upper intake level despite convenient packaging. It is not well suited to routine self-directed use.

AI assessment of the formula, label and price. How scoring works

Nutrient quality48

Potassium iodide offers strong form quality and complete active-dose disclosure. The above-limit amount creates a meaningful risk of thyroid disruption.

.
Ingredient transparency89

The iodine form and active amount are clearly stated. Complete capsule ingredients and the intended supervision context are not supplied.

.
Customer satisfaction73

The supplied average rating is very strong and backed by a substantial review pool. No review text is available to assess recurring complaints or firsthand tolerance and ease of use.

.
Value for money39

The high-risk dose poorly justifies the formula cost. Reasonable serving cost does not compensate for a dose that is poorly suited to routine use.

Report overview
A+ Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyA+ Value
The clearly stated 1,500 mcg iodine dose exceeds the 1,100 mcg upper intake limit, making the amount the main concern. Excess iodine can disrupt thyroid function. Potassium iodide identifies the chemical form, and the cost per serving is low.
How this ingredient is rated

Active Ingredient Quality & Bioavailability100

Potassium iodide clearly identifies the iodine form. Seaweed-specific sourcing concerns don't apply because no marine source is recorded.
Iodine Form & Bioavailability
The iodine comes from potassium iodide, an identified iodide salt.
Marine Source Purity & Sourcing
No marine source is recorded, so seaweed-specific sourcing concerns don't apply; this doesn't confirm freedom from contaminants.

Dose, Safety & Label Transparency28

The 1,500 mcg dose exceeds the daily-support range and the 1,100 mcg upper intake limit, despite being clearly stated.
Dosage Efficacy for Daily Support
The 1,500 mcg iodine serving is well above the 150–300 mcg daily-support range.
Dosage Safety & Upper Limits
The 1,500 mcg serving exceeds the 1,100 mcg upper intake limit; excess iodine can disrupt thyroid function.
Elemental Iodine Transparency
The active iodine amount is clearly stated as 1,500 mcg per serving.

Value100

Each serving has a low cost.
Price Per Effective Serving
The cost per serving is low.
