Regulation

Limited claim language makes supplement and food companies harder to invest in. Existing food and drug rules are portrayed as lagging behind current methylation, genetics, epigenetics, and individualized nutrition science. Food and supplement companies generally cannot claim that their products treat, reverse, or prevent medical conditions. Food labeling rules can prevent simple substitution of methylfolate for folic acid in fortified foods despite biological arguments for it. U.S. pharmaceutical companies can make disease-treatment claims after successful FDA trials.
