Reference dose
1.2 g trial dose

The dose audit marks a product MET when the amount on its label, as two readers transcribed it, is at or above this figure, and UNDER otherwise. An ingredient inside a proprietary blend has no disclosed dose, so it is counted as undosed, never assumed adequate. A reference dose is the amount a cited study or guideline used; it is not a recommendation for anyone. Every reference dose and its source: how we rate.
