Vitamins and other dietary supplements are a $30 billion industry in the US. In addition to the bottles lining drugstore shelves, those products include a niche that promises to meet customers’ unique needs based on their specific data.
Those data come in a few different forms. Like Nourish3d, some other companies, including care/of and Persona, use an online questionnaire that covers questions such as goals and current diet. Persona and care/of then recommend personalized vitamin packs for customers to order.
Other companies use DNA testing to make their recommendations. PureGenomics, available only through healthcare providers, uses the results of 23andMe’s direct-to-consumer SNP test to sell its supplements.
