We confirmed the label amount for each of the 8 ingredients above, then compared each figure against the doses most commonly cited in published research for that specific ingredient. Six of the eight have real peer-reviewed research behind them at the ingredient level; two (Chondroitin and Quercetin) are dosed well below the amounts typically used in that research. Neither is disqualifying on its own, but both are worth knowing before you order.
