Nearly half of American adults use supplements regularly, generating over $30 billion a year in sales, according to the National Institute of Health (NIH). A new study tried to find out why so many people put their trust in supplements despite of much uncertainty over their health effects. What’s even more puzzling is that many supplement users don’t think of supplements as related to nutrition but rather to overall health. It’s almost like a lifestyle issue, according to the study. Typical users are older, eat well, are physically active, manage their weight, don’t smoke, and usually have a higher educational and social status than non-users.
