Iodine is a crucial nutrient, primarily known for its role in promoting healthy thyroid function. While it is essential for overall health, there is limited research on the specific effects of Iodine in preventing or treating Alzheimer's disease. Current scientific literature does not provide substantial evidence to suggest that Iodine supplementation can directly prevent or alleviate the symptoms of Alzheimer's disease.
However, some studies have explored the potential relationship between Iodine status and cognitive function. Adequate Iodine intake may indirectly support cognitive health by maintaining thyroid hormone levels, which are crucial for brain development and function. Additionally, Iodine deficiency can cause cognitive impairment, particularly during fetal development and early childhood. Ensuring optimal Iodine levels is important for overall brain health, but its role in preventing or treating Alzheimer's disease remains unclear.
