Iodine

Iodine is a mineral for thyroid function found mostly in iodized table salt, fish, and highest in seaweed. Despite most first world diets being sufficient in iodine, it may benefit those who do not consume seafood and are also in a high risk population (pregnancy and intentional salt restriction).

Quick Answer

What it is

Iodine is a mineral for thyroid function found mostly in iodized table salt, fish, and highest in seaweed. Despite most first world diets being sufficient in iodine, it may benefit those who do not consume seafood and are also in a high risk population (pregnancy and intentional salt restriction).

Key findings

  • Grade C: C-Reactive Protein (CRP) (Metabolic Health)
  • Grade C: Interleukin 6 (Metabolic Health)
  • Grade C: Serum T4 (Hashimoto's disease)

Safety

  • Despite most first world diets being sufficient in iodine, it may benefit those who do not consume seafood and are also in a high risk population (pregnancy and intentional salt restriction).
