What Functional Nurses Should Know about the Legal Aspects of Functional Medicine

1. The Term Functional Medicine Does Not Inherently Mean Practicing Medicine

 Pam describes functional medicine as an approach or framework for looking at health that considers the whole person, including nutrition, sleep, stress, and environmental and lifestyle factors. In our discussion, she explains that functional medicine is not itself a separately licensed profession. It is an approach that different professionals can incorporate into their work within the authority they already hold.

 A physician may use a functional approach to practice medicine. A non–advanced practice nurse may use a functional approach to provide nursing services. A health coach may incorporate functional medicine concepts into education and coaching. The approach informs the work; the professional’s license and applicable law determine the services they may provide.

 For that reason, Pam does not begin her analysis with the words functional medicine. She begins with what the individual is actually doing. Are they independently diagnosing a medical condition, prescribing, or selecting medical treatment? Or are they providing education, promoting health, and performing activities within their nursing scope?

Functional medicine education does not expand a nursing license. As Pam explains, however, using a functional framework does not automatically narrow the scope a nurse already has either.

2. The Role of RN and LPNs Share a Similar Focus in Functional Medicine

In the episode, I explain why FNA includes both license types in its educational opportunities: practical and vocational nurses are nurses too, and their training and experience can bring value to the specialty of functional nursing and health promotion. 

We discuss how nursing responsibilities can differ in a hospital setting, where LPNs typically work within a more directed scope, with different assessment and supervision requirements. In functional medicine, however, RN and LPN services may overlap considerably when centered on education, nutrition and lifestyle support, and health promotion.

Pam and I emphasize that each nurse’s services must align with their individual scope of practice, applicable supervision requirements, and state regulations. This differs from NP practice, which may include diagnosing medical conditions and developing medical treatment plans when authorized. The non–advanced practice nursing services discussed here focus on education, wellness support, collaboration, and appropriate referral.

3. Functional Medicine Certification and Nursing Licensure Serve Different Purposes

We also address the claim that it is unlawful for a non–advanced practice nurse to obtain a certification as a functional medicine practitioner.

Pam explains that obtaining an educational certification with that title is not inherently unlawful simply because the individual is a non–advanced practice nurse. A functional medicine certification represents additional education and credentialing; it does not grant a new professional license or authorize medical practice.

How that credential is presented matters. Nurses should clearly identify their nursing license, explain the source of their functional medicine certification, and accurately describe the services they offer. A privately issued certification should be identified as such, including its issuing organization, rather than presented in a way that suggests a state-issued license or advanced practice authority.

For example, a client should not be led to believe that a non–advanced practice nurse holding a functional medicine practitioner certification is a nurse practitioner. Websites, professional introductions, and client agreements should make those distinctions clear. 

4. Supplement Education and Medical Treatment Require Different Considerations

Supplement recommendations are a frequent source of questions among non–advanced practice nurses entering the functional medicine space.

Pam distinguishes education and recommendations for general health and wellness from selecting a supplement specifically to treat or manage a diagnosed medical condition. The purpose and context of the recommendation matter.

The berberine example: educating a client versus selecting treatment

We discuss how a non–advanced practice nurse can educate a client diagnosed with type 2 diabetes about berberine, the research on blood sugar, and potential risks and interactions. Pam contrasts that discussion with telling a client with diabetes to take a particular dose of berberine as treatment for their diabetes, which moves into selecting medical treatment.

The educational approach is to help the client understand the information and identify questions or options to discuss with their treating physician. An illustrative, paraphrased example could sound like this:

“There is research on berberine and blood sugar. We can review that information and potential safety concerns so you can ask your treating physician whether it is appropriate for you.”

When a supplement is being considered as part of treatment for a diagnosed condition, Pam describes involving the treating provider. Non–advanced practice nurses can support informed conversations and collaboration while keeping their own recommendations within the authority of their license.

To simplify: Non–advanced practice nurses can generally recommend supplements for health and wellness within their scope of practice, but they cannot independently recommend supplements as treatment for a medical condition. They may provide education and resources about evidence-based supplement options for clients to discuss with their treating medical provider, who can determine whether those options are appropriate for their treatment plan.

5. Nutrition Coaching Should Be Evaluated by Its Purpose

Pam discusses general nutrition education and individualized wellness guidance separately from prescribing a therapeutic diet to treat a medical condition.

The ketogenic diet example: making a direct treatment recommendation versus providing education

In this episode, I explain the difference between prescribing a ketogenic diet to treat a client’s seizure disorder and educating that client about relevant research and resources to discuss with their medical provider.

An illustrative, paraphrased educational conversation could sound like this:

“There is research on ketogenic diets for certain seizure disorders. I can share information and resources for you to discuss with your treating provider, including whether this approach is appropriate and what supervision would be needed.”

The distinction is between independently selecting disease-specific treatment and helping a client understand potential approaches they can explore with the professional responsible for their medical care.

Helping clients understand nutrition information, explore daily habits, and prepare questions for their healthcare team can be part of a supportive wellness relationship.  

To simplify: non–advanced practice nurses can generally provide nutrition coaching for health and wellness within their scope of practice, but they cannot independently prescribe a therapeutic diet to treat a medical condition. They can provide education about therapeutic dietary approaches for clients to discuss with their medical team.

6. Laboratory Testing Involves Two Separate Questions

Pam breaks the laboratory discussion into two parts: who is authorized to order the test, and how the non–advanced practice nurse uses the results.

Facilitating a physician’s order is different from independently ordering under a nursing license.

We discuss arrangements in which a non–advanced practice nurse facilitates access to testing through a partnering laboratory, while a physician places the actual order. This is different from the nurse independently ordering tests under their own license. The arrangement must meet the applicable state requirements and the laboratory’s procedures.

For blood testing performed through laboratories such as Labcorp or Quest, we discuss how non-advanced practice nurses may use a partnering laboratory’s physician-ordering arrangement. 
 

What about functional tests and direct provider or reseller accounts?

We also discuss functional testing, including Precision Analytical’s DUTCH test, which uses noninvasive urine collection to assess hormone patterns. In our conversation, we explore its use for functional information rather than independently diagnosing a medical condition.

Similar laboratories that offer non-invasive functional medicine tests not used to diagnose medical conditions may offer provider or reseller accounts to professionals other than physicians or advanced practice clinicians, potentially including RNs, dietitians, and licensed acupuncturists. Eligibility depends on the laboratory’s policies, the specific test, the professional’s scope of practice, and applicable state requirements. 

We emphasize reviewing the relevant Nurse Practice Act, board of nursing requirements, and laboratory policies before establishing a direct ordering arrangement. When those requirements are unclear, qualified healthcare counsel can help interpret them and determine an appropriate path forward.

How the results are used matters just as much.

Reviewing results for education and appropriate referral is different from independently using those results to diagnose a medical condition or select medical treatment.

We also discuss communication with the client’s established medical provider. In my own practice, I obtain a release of information to support coordination when concerning results arise.  Pam identifies that document as one she commonly helps clients prepare.

Clear procedures for communicating results, escalating concerns, and coordinating follow-up are important parts of planning these services.

7. Can Nurses Offer Health Coaching Services in States Where They Are Not Licensed? (applicable to NP, RN, LPN/LVN)

Many nurses licensed in a noncompact state want to build a virtual business that reaches clients beyond their home state. We discuss whether a separate coaching or consulting service can make that possible.

For nursing services, the client’s location is central to determining licensure requirements. A nurse must have the required authorization to practice where the client is located, whether through an individual license or an applicable practice privilege. A private coaching credential does not replace that authorization for services that constitute nursing practice.

Pam cautions against offering the same service in multiple states while simply calling it nursing in the home state and coaching everywhere else. For nurses seeking to offer the same nonclinical services across jurisdictions, she describes helping them structure and present those services consistently as coaching, with careful attention to the activities, marketing, agreements, and documentation.

A separate clinical practice and coaching business require distinct services.

We also discuss the example of an NP with a medical practice in California (non compact state) and a separate coaching business serving clients nationwide. I describe a graduate who worked with an attorney to establish separate websites and service offerings. Pam explains that clinical care and coaching must be meaningfully distinct, with clear communication about the capacity in which the professional is acting.

Nurses considering a nursing business in their licensed state and separate coaching or consulting services elsewhere should work with qualified healthcare counsel to assess whether that structure is appropriate. Legal review should address each intended jurisdiction and the actual services provided, rather than assuming a private credential allows nationwide practice.

The opportunity discussed in the episode is to build an appropriately structured coaching service where permitted. It requires more than changing a title or adding a disclaimer. Working with counsel can help clarify professional boundaries, support compliance, and reduce avoidable risks to a nursing license.

8. Inaccurate Legal Advice and Fear-Based Marketing Can Hold Nurses Back

One of the most candid parts of this episode addresses a difficult reality: receiving advice from an attorney does not automatically mean that advice reflects expertise in the particular issue being discussed.

I open the conversation by sharing a personal experience involving a competitor’s demand letter about the use of functional nursing terminology. Two attorneys initially advised me to comply with demands that would have meant shutting down FNA’s website and other platforms. When I sought opinions from attorneys specializing in trademark law, their assessment was very different. As I recount in the episode, they explained that a company could not simply monopolize a nursing specialty by claiming exclusive use of the terminology describing it. I share this experience to emphasize the importance of working with qualified legal counsel who has expertise in the specific area of law relevant to your situation. Some attorneys may offer advice without the necessary experience or sufficient research, leading to inaccurate guidance that can have significant consequences for your business.

Pam explains that she also encounters clients who have received advice from attorneys unfamiliar with healthcare law. In the functional nursing space, she identifies a recurring misunderstanding: an attorney hears functional medicine, recognizes that a non–advanced practice nurse cannot independently practice medicine, and concludes that the nurse cannot work in that space at all.

That skips the central question: what services is the nurse actually providing? Education, health promotion, and wellness support require a different analysis from independently diagnosing a medical condition or selecting medical treatment. As Pam explains, a functional framework does not expand a nurse’s scope, but it does not automatically narrow the scope the nurse already has either.

We also directly address fear-mongering in legal marketing.

I describe hearing about webinars or videos that warn nurses they could be sued or lose their license for offering functional medicine services, then position an expensive program as the way to avoid those consequences.

Pam shares that she has personally encountered lawyers who exaggerated risks in their conversations with her—risks she says she recognized as inaccurate because of her own legal background. She expresses concern about using fear to sell legal services.

The takeaway is not to disregard legal guidance. It is to seek guidance that identifies the actual legal issue, explains how it applies to the proposed services, and offers practical steps to address it. A useful review should account for the nurse’s license, relevant jurisdictions, supervision requirements, marketing, agreements, and laboratory arrangements. An alarming blanket statement about functional medicine does not replace that analysis.

For non–advanced practice nurses exploring starting a functional medicine business, this distinction matters. Nurses deserve clear, informed guidance that helps them understand both their professional boundaries and the opportunities available within them.

The Role of Functional Nurses

Our conversation highlights the value nurses can bring through coaching, education, wellness support, and collaboration with the healthcare team.

Nurses can help clients discover obstacles impacting their health, better understand health information, and work toward sustainable lifestyle changes within the boundaries of their practice.

During the interview, I share an example of identifying that a client could not afford his diabetes medication. Communicating that barrier to his physician helped connect him with support while I focused on nutrition and lifestyle education. It illustrates how nursing support can complement medical care.

FNA welcomes advanced practice and non–advanced practice nurses interested in learning a functional approach. For non–advanced practice nurses, the overlap in wellness education and lifestyle support creates meaningful opportunities to use that education. Each nurse’s services must still reflect their own license, including any supervision requirements. NPs may incorporate the same functional framework into advanced practice services when authorized to do so.
