What this map is, and what it is not
Emerging wellness science covers many different fields. They do not stand at the same point. Within one field you can find an approved medicine, a promising trial, an animal finding and a marketing claim, all using the same vocabulary. This page maps the kind of evidence each field depends on, so you know which question to ask first. It does not rank fields, and it does not give counts of studies. Counts change, and any figure we publish comes only from dated records in the Research Library, so none are claimed here.Four questions that apply everywhere
- Is it a field, a mechanism, a technology, a product or a test? A field is not a treatment, and a mechanism is not a result.
- Who was studied? Cells, animals and people answer different questions. Early laboratory work is not a substitute for studies in people. [1]
- What was measured? A biomarker is a stand-in, not the outcome, and it earns trust only after extensive evidence that it predicts how people feel, function or survive. [2]
- What is the status? Approved, investigational or commercially speculative, for which product and which use. Translation is the process of turning laboratory, clinic and community observations into interventions that improve health. [3]

Reading the stages
Most medical products pass through a series of studies. Clinical trials follow a typical series from early, small-scale Phase 1 studies to late-stage, large-scale Phase 3 studies. [1] A field can have products at every stage at once. The FDA keeps a list of licensed cellular and gene therapy products, [4] but a list of named products is not the same as evidence for every treatment using similar words. An approval covers a specific product and use.Some tests and devices are judged by other standards. A 510(k) device clearance rests on equivalence to an earlier device, [5] and registration of an establishment or listing of a device does not denote approval. [6] Compare any claim against the official record for the exact product.

Frequently asked questions
Does more research on a field mean it works?
No. Volume of research tells you the field is active, not that its products are effective. What matters is the design, the outcomes and the exact product.
Why do you not show how many studies exist?
Counts shift as new work is added, retracted or reclassified. We only give numbers drawn from dated records.
Can a whole field be called established or investigational?
Usually not. Approval and evidence attach to specific products, uses and populations, so one field often holds several statuses at once.
Does an approved product in a field validate the others?
No. An approval is for a specific product and use. The FDA's licensed list names individual products. [4]

A safety note
A field being active does not make an offered treatment safe or proven. Check the status of the exact product with the regulator, and talk with a clinician before acting on any emerging claim.
