Help with cognition
A new study has found that iodine may help improve cognition. The study looked at the effect of iodine on cognitive function in rats. The study found that rats who were given iodine showed improved performance on tests of learning and memory. The researchers believe that iodine may help to improve cognition by increasing levels of a brain chemical called noradrenaline. (5)
Noradrenaline is known to be important for learning and memory, and previous studies have shown that iodine deficiency can lead to lower levels of noradrenaline in the brain.
