The evaluators disagree. FDA (1969) does not permit it in food, while SCF (2000) keeps an ADI for it.

Questions about cyclamates
Is cyclamate harmful?
JECFA (2009) kept the ADI of 0-11 mg/kg body weight, expressed as cyclamic acid. Of the four maximum use levels considered (250, 500, 750 and 1000 mg/kg), only the lowest, 250 mg/kg, was not likely to lead to intakes above the ADI for high consumers, including children; a level of 350 mg/kg also gave intakes below the ADI.
Is E952 permitted in Vietnam?
Yes. Cyclamic acid (INS 952(i)), calcium cyclamate (952(ii)) and sodium cyclamate (952(iv)) are listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food.
Can children and pregnant women have E952?
In 2009 JECFA considered four maximum use levels for cyclamates (250, 500, 750 and 1000 mg/kg). Only the lowest, 250 mg/kg, was not likely to lead to exposures above the ADI (0–11 mg/kg body weight, as cyclamic acid) for high consumers, including children; JECFA also noted that a level of 350 mg/kg gave exposures for high consumers, including children, below the ADI. This is a JECFA evaluation, not an EFSA opinion or the current EU rule. The source says nothing specific about pregnant women. If you have a particular health condition, ask a doctor.
