Not a regulated product. No approval pathway exists for this intervention in any market, and none is required to practise it.

Evidence so far is from observational studies in people.

If you are tracking this yourself

measures the human studies used, by how repeatable they are

Repeatability is whether the same person measured twice gets the same number. It is not statistical significance. It informs study or protocol design only, never advice for a person.
