Which mineral is a component of the hormone thyroxine, which controls metabolism?

Calcium
Magnesium
Iodine
Zinc

The correct answer is: Iodine

The correct choice is iodine because it is an essential component of the hormone thyroxine (T4), which plays a crucial role in regulating metabolism in the body. Thyroxine is produced by the thyroid gland, and iodine is a critical ingredient in its synthesis. Without sufficient iodine, the body cannot produce enough thyroxine, which can lead to hypothyroidism and associated metabolic issues. Understanding the role of iodine is key for health coaches, as advising clients on adequate iodine intake can help maintain healthy thyroid function and overall metabolic balance.
