Abstract
Since its inception in 2004, Canadian regulation of natural health products (NHPs) has been evolving. Implementation of the novel Natural Health Products law by Health Canada, the national regulatory agency, has been responsive to both consumer desires for novel products for health care, but also potential concerns over product safety. The agency has developed numerous webpages explaining its approach to this new regulatory category, which has included regulations and guidance documents and refinement of both. Due to its many layers, the information is not very transparent. In addition, the information has been changing and is constantly under revision. For this reason, a review of the legislation, regulation and policies was embarked upon which led to the preparation of an overview of up to date information that we hope will be useful to those who plan to pursue the Canadian NHP system.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
