What Are Iodine Supplements and How Do They Work?
Iodine is a trace mineral required by the thyroid gland to produce hormones that regulate energy, temperature control and metabolic function. Since the body cannot create iodine, it must come from dietary sources or supplementation.
Iodine supplements work by providing a reliable daily intake, helping maintain balanced thyroid activity. Some formulas also include minerals like selenium or zinc to support hormone conversion, immune resilience and overall wellbeing.

Why Iodine Is Important
Iodine supports thyroid activity, metabolism, hormone balance and energy regulation. Low intake is more likely in those who avoid seafood, dairy or eggs, or follow plant-based diets. Supporting iodine status can help reduce the risk of thyroid issues such as hypothyroidism and goitre.
Iodine is an essential mineral crucial for thyroid health, metabolism regulation and immune function. It also plays an important role in cognitive development, particularly during pregnancy and early childhood. For complete thyroid and metabolic support, iodine works alongside key nutrients such as selenium, zinc and vitamin D. These essential vitamins and minerals support hormone production, energy balance, immune strength and overall wellbeing. Individuals also commonly pair iodine with Immunity Supplements for broader immune system support.
