What is the recommended daily Iodine RDA compared to a single concentrated kelp supplement tablet?
Answer
The RDA hovers around $150 ext{ extmu}g$ daily, while some tablets contain $225 ext{ extmu}g$ or more.
The recommended dietary allowance (RDA) for iodine for a general healthy adult is established at approximately $150 ext{ extmu}g$ per day. This benchmark serves as the necessary amount to maintain proper thyroid function and metabolism. However, kelp supplements deliver iodine in a highly concentrated form, frequently containing $225 ext{ extmu}g$ in a single tablet, which immediately exceeds the established daily RDA. When consumers take more than one tablet or combine the supplement with other iodine sources, they rapidly move into consuming potentially harmful levels significantly higher than the safe upper limit.
