The health freedom movement is a libertarian coalition that opposes regulation of health practices[1] and advocates for increased access to "non-traditional" health care.[2]
The right-wing John Birch Society has been a prominent advocate for health freedom since at least the 1970s, and the specific term "health freedom movement" has been used in the United States since the 1990s.[3][4]
Vitamins and supplements have been exempted in the US from regulations requiring evidence of safety and efficacy, largely due to the activism of health freedom advocates. The belief that supplements and vitamins can demonstrably improve health or longevity and that there are no negative consequences from their use, is not widely accepted in the medical community.[5] Very rarely, large doses of some vitamins lead to vitamin poisoning (hypervitaminosis).[6]
