About this product

The label presents molecular iodine, potassium iodide, and sodium iodide in a veggie capsule. Three readily absorbed iodine forms are named, but the repeated amount makes total exposure unclear and even the lowest reading is excessive.

Iodine can support thyroid-hormone production when intake is inadequate. Unclear total exposure makes it difficult to judge whether the serving is appropriate, especially for regular use.

Verification of the intended serving amount is the practical priority before purchase or use. Convenience and value do not compensate for uncertainty around a thyroid-active nutrient.

Who is it for
  • people using a specialist-supervised iodine regimen
  • people whose diet provides too little iodine
Best for
  • targeted iodine support
  • supporting normal thyroid-hormone production when iodine intake is low

Pros

  • Names the iodine sources used
  • Three readily absorbed iodine forms are named
  • Veggie capsule keeps use straightforward

Cons

  • The repeated amount makes total exposure unclear and even the lowest reading is excessive
  • Safe serving suitability cannot be judged confidently
  • Targets only the thyroid-related iodine pathway

Warnings

  • Confirm whether 12,500 mcg is the combined serving or applies to each iodine form.
  • Even the lowest interpretation exceeds normal nutritional use and calls for medical supervision.
  • Potassium and sodium iodide may alter thyroid control in people with thyroid disease or those using thyroid medication.

Product analysis

58 out of 100
A potentially useful iodine formula is undermined because the repeated amount makes total exposure unclear and even the lowest reading is excessive. Confirm the actual total dose before considering it.

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

Nutrient quality42

Iodide forms support high absorption quality. The extreme intended amount creates a major thyroid-safety concern regardless of form.

.
Ingredient transparency76

The iodine forms are named, but repeated amount entries do not clearly state their contributions to the total. Dose ambiguity, absent inactive ingredients, and limited use context reduce safe interpretability.

.
Customer satisfaction72

The supplied average rating is strong and backed by a large 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
C Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyB+ Value
The very high iodine dose is the main drawback, despite clear disclosure and a moderate cost per serving. Each serving supplies 12,500 mcg, well above the adult upper intake limit. The blend proportions and marine sourcing details are also unclear.
How this ingredient is rated

Active Ingredient Quality & Bioavailability64

It combines molecular iodine with potassium and sodium iodide, but their proportions are unknown. Its marine source lacks organic or geographic sourcing details.
Iodine Form & Bioavailability
The blend includes molecular iodine and two iodide salts; the iodide forms are preferred here, but their actual shares are unknown.
Marine Source Purity & Sourcing
The marine source has no stated organic status or geographic origin in the available information, leaving its sourcing less clear.

Dose, Safety & Label Transparency28

The iodine amount is clearly disclosed, but the serving provides far more than the daily maintenance range and exceeds the adult upper intake limit.
Dosage Efficacy for Daily Support
The 12,500 mcg serving is far above the 150–300 mcg range used for daily maintenance.
Dosage Safety & Upper Limits
The 12,500 mcg serving exceeds the 1,100 mcg adult upper intake limit; excessive iodine can disrupt thyroid function.
Elemental Iodine Transparency
The iodine amount and its sources are explicitly disclosed.

Value80

The cost per labeled serving is moderate.
Price Per Effective Serving
The cost per serving is moderate.
