Boundary

A constituent measurement is a fact about material at a stated preparation, not a statement about what that material does in a person. An adverse-effect or genotoxicity record is an observation reported in a source, most often in an animal or laboratory model. Neither is a Metatron Health conclusion about causality, human risk or benefit, and the absence of a record is not proof that a preparation is safe. Nothing here is diagnosis, prescribing or individual medical care.
