Score breakdown
Grades are based on five things: how clearly the label declares its ingredients, how the doses compare with Australian daily targets and upper limits, TGA register status, ingredient quality and manufacturing. No brand pays to be rated or listed. Anything the label doesn’t declare is shown as No data.
