## A good fit for

- People seeking a capsule-form iodine supplement rather than getting iodine through table salt.

## Less suited to

## Customer feedback

Customer feedback highlights perceived effectiveness, product quality, ease of swallowing, and a small capsule size, with some customers reporting feeling better quickly. These are customer perceptions, not evidence of a clinical effect.

Aggregate ratings lean positive overall, but do not explain individual experiences.
