The Council for Responsible Nutrition (CRN) says a recently introduced bill in the Massachusetts, US, legislature is “even more prohibitive” than the law enacted in New York state last year. The new bill prohibits the sale of over-the-counter diet pills and supplements for weight loss or muscle building to people under 18 years old. It would require supplements marketed, labeled or otherwise promoted for weight loss or muscle building to be placed behind the retail counter in a locked case.
