Currently retailers, such as those working in health food and supplement establishments, are not licensed in the United States. Retailers interested in using nutrition tools are subject to the statutes of the relevant nutrition laws for their state. 

When can you use nutrition tools in your profession:
States where nutrition care is governed by a licensure with exclusive scope of practice frequently have an exemption for retailers that limit employees to dispensing “general, non-medical, nutrition information” about food and dietary supplements. Generally, non-medical information means information about the use, preparation, and/or scientific information about the food or products and does NOT allow for advice or recommendations specific to an individual’s medical condition even if given in response to a customer’s question.

If the nutrition law in your state is a licensure without exclusive scope of practice then you can practice nutrition care without being certified/licensed as a nutrition care provider. However, if specific title protections exists in the law, you may not use any protected title in advertising or practice.

Check your nutrition state law to see if it is: a licensure with exclusive scope of practice; a licensure without exclusive scope of practice; you fall within the listed exemptions of the law; or there is no law for your state.
