Iodine is an essential trace mineral critical for the production of thyroid hormones, which regulate metabolism, growth, and energy levels. It plays a vital role in maintaining the proper function of the thyroid gland, impacting physical performance and recovery in active individuals. Inadequate iodine levels can lead to thyroid dysfunction, affecting endurance and overall energy availability.
In the context of dietary supplements, iodine helps athletes and physically active people maintain optimal metabolic rates and support general hormonal balance, which is essential for muscle repair and energy management. It is commonly included in multivitamin formulations and targeted thyroid-support supplements.
Because iodine cannot be produced by the body, consistent dietary intake is crucial, especially for those who sweat heavily during intense exercise, as iodine can be lost through perspiration.
