There is a study out on a number of older supplements that demonstrated that not only was there huge variations in the levels found in the supplement compared to what was listed on the label ranging from 0% to several times above the label but also varied between batches. In that sort of scenario, rotating several different supplements helps to manage those issues but if one has confidence in some of the more modern product(s), then one can dispense with using multiple supplements.
