Shouldn't these formulations be proven safe before they are allowed? When there are questions around critical issues such as if it's deposited in chelated or free toxic form, it just looks like experimentation on humans. There needs to be a broad reaching study to determine if gadolinium loses chelation under a variety of circumstances that can occur in different regions of the human body over a long period of time. It can take years for a single administration of gadolinium to stop appearing in urine. Why is there no long lasting study that tests if all the gadolinium in urine is in chelated form, after 1 year, 2 years, and so on? Same for gadolinium deposited in skin and other regions.
