Iodine is an essential nutrient that plays a crucial role in human health. It is a mineral that is needed for the production of thyroid hormones, which are responsible for regulating metabolism, growth, and development in the body. Iodine is also important for brain development, particularly during fetal development and early childhood. A deficiency in iodine during pregnancy can lead to cognitive impairments and developmental delays in the child. Iodine plays a pivotal role in maintaining a healthy immune system due to its antiviral, antibacterial, and anti-inflammatory properties. Iodine is also important for breast health. It has been shown to help regulate breast tissue growth and prevent the development of breast cancer.
