In the US, supplements are sold without any pre-market review of whether they work or whether they are safe. A manufacturer does not have to show the FDA either one before a bottle reaches a shelf; regulators act after harm is reported, not before. So most of what is here rates limited or not enough evidence. That is the finding, not a gap we intend to fill. Doses are reported as what trials administered, never as what to take.
