Just last month, Sweden moved to change its vitamin D and iodine limits; before that, Sweden started a process to adopt the supplement limits set by European Union (EU) regulators. The point is, once we start moving down this road, it will become more and more difficult to prevent similar restrictions in the US.

Last month, Swedish authorities released a proposal to limit vitamin D dosages to 4,000 IU (100 mcg) and iodine doses in supplements to 200 mcg. For vitamin D, a 4,000 IU limit may not seem all that bad, but the problem is that it limits the tools available to patients and integrative doctors unnecessarily.
