can be used in dietary supplements as a source of iodine

Sodium iodide (NaI) can be used in dietary supplements as a source of iodine, though it is less common than potassium iodide. Here are some key points about sodium iodide in dietary supplements:

1. Function: Sodium iodide provides the essential mineral iodine, which is crucial for the synthesis of thyroid hormones. These hormones regulate metabolism, growth, and development.

2. Bioavailability: Sodium iodide is readily absorbed by the body, making it an effective means of delivering iodine.

3. Usage: It can be found in some multivitamin and mineral supplements, as well as in specific iodine supplements designed to prevent or treat iodine deficiency.

4. Safety and Dosage: The recommended daily allowance (RDA) for iodine varies by age, sex, and life stage. For adults, it is generally around 150 micrograms per day. Excessive iodine intake can lead to thyroid dysfunction, so it is important to adhere to recommended dosages.

5. Forms and Combinations: Sodium iodide may be included in dietary supplements either on its own or in combination with other vitamins and minerals. It can also be found in iodized salt, which is a common source of dietary iodine in many countries.

6. Regulation: As with all dietary supplements, products containing sodium iodide are regulated to ensure they are safe for consumption and that they contain the amount of iodine stated on the label.
