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).

Technically an Omega-3 fatty acid, TTA is a non-metabolizable fatty acid that cannot be used for energy and may be able to burn fat via mechanisms similar to Conjugated Linoleic Acid. Lacking studies in humans at the moment, TTA appears to be a promising future candidate for fat loss and health.
