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

Nutrient Quality20

The iodine form is not clearly disclosed, leaving its quality uncertain. The sea-iodine name alone does not settle a comparison with clearly identified sources.

Ingredient Transparency63

The iodine amount is clearly stated. Its form is unspecified, making the source harder to compare.

Value For Money100

The low serving cost offers good value for iodine supplementation. A larger amount does not necessarily provide more benefit.

Customer Satisfaction93

Customer ratings are very positive. The large review history gives an established picture of satisfaction, without proving effectiveness.

Product Focus45

The formula focuses on iodine for normal thyroid function when intake is low. The serving is well above the usual adult daily reference, without establishing a stronger metabolism benefit.
