Functional vs integrative vs holistic psychiatry

These three terms get used interchangeably, but they describe different things. Here is a plain-language guide, and where Sphosh Health fits.

Reviewed by Dr. Koichi Tanji, ND, LMHC · 6 min read

If you have researched mental health care beyond the standard model, you have probably seen the words holistic, integrative, and functional psychiatry. They overlap a lot, and clinics use them loosely, so it is easy to get lost. Here is the short version, then a little more on each.

The short version

All three widen the lens beyond brain chemistry alone. The differences are mostly about emphasis: holistic looks at the whole person, integrative combines conventional and complementary tools, and functional digs into the biological root causes with testing. In practice, good clinicians blend all three.

Holistic psychiatry

Holistic psychiatry treats the whole person, mind, body, and lifestyle, rather than a diagnosis in isolation. It considers sleep, nutrition, stress physiology, relationships, and meaning alongside symptoms. Read our overview of how holistic psychiatry works.

Integrative psychiatry

Integrative psychiatry starts from the conventional model, diagnosing a condition such as depression or anxiety, and expands the toolbox. An integrative provider may use standard treatments alongside nutrition, lifestyle change, and evidence-informed natural therapies, chosen for the individual.

Functional psychiatry

Functional psychiatry changes the questions it asks. Instead of stopping at the diagnosis, it asks what is driving the symptom biologically, and uses lab testing to look for contributors such as nutrient status, inflammation, gut health, and hormones. Our article on naturopathic psychiatry covers this root-cause lens in more depth.

So which one is Sphosh Health?

All of the above, delivered by one provider. Dr. Koichi Tanji is dual-trained as a Naturopathic Doctor and a Licensed Mental Health Counselor, so psychotherapy, integrative medicine, and functional, root-cause assessment sit together in a single coordinated plan rather than being scattered across separate providers. If therapy or medication alone has not fully worked, that combined view is often where the missing piece shows up, whether that is anxiety, low mood, brain fog, or burnout.
