Glucose and metabolic health markers is closer to a research marker, so it should be read separately from a directly felt benefit.

Human evidence exists, but it is mostly in patient or disease contexts, so the score is handled conservatively.

Representative tier calculated from paper evidence that passed the collection audit.
