Norwegian Kelp
Nature's Harmony
Overview
Nature's Harmony Norwegian Kelp provides a substantial dose of iodine (455 mcg), which can effectively address iodine deficiency. However, this dose is significantly higher than the typical recommended daily intake for adults (75-150 mcg) and exceeds the upper safe limit recommended by some authorities (e.g., 500-600 mcg/day for American/European guidelines). While short-term studies on kelp at similar doses have not always shown adverse thyroid effects, chronic intake at this level carries risks for individuals not truly deficient or those with underlying thyroid conditions, which are often undiagnosed.
