Salt
The amount of iodine and the specific iodine compound added to salt varies from country to country. In the United States, the Food and Drug Administration (FDA) recommends [21 CFR 101.9 (c)(8)(iv)] 150 micrograms of iodine per day for both men and women. US iodized salt contains 46–77 ppm (parts per million), whereas in the UK the iodine content of iodized salt is recommended to be 10–22 ppm.
Iobitridol
Xenetix 300 of Guerbet (Roissy, France) contains Iobitridol in 300 mg iodine/ml concentration. Recommended mean doses are 1.1 to 2.8 ml/kg body mass corresponding to 0,33 to 0,84 g iodine/kg human body mass. Injected into veins it will be filtered out by the kidneys. It is used also to fill joints or the uterus.
