What are the risks of saccharin?

There are no proven health risks for saccharin or other artificial sweeteners, states Mayo Clinic. Although studies conducted in the 1970s seemed to indicate a link between saccharin consumption and bladder cancer, subsequent research has not shown any risk, and the FDA does not require warnings for products containing saccharin.

Artificial sweeteners are regulated as food additives by the FDA, according to Mayo Clinic, and they must be reviewed by the FDA before they go on sale. The FDA establishes an acceptable daily intake for each artificial sweetener it reviews, and this number is typically placed at 100 times lower than the smallest amount that might cause health problems.
