Resting on one’s laurels is rarely advisable, and in the case of heart health supplement makers, it’s not even feasible. That’s because there is always new science to uncover behind the supplements they sell, from the tried and true to the pioneering. Then again, maybe they should all just relax, since the most important cardiovascular-support nutrients basically sell themselves. They are just that important to consumer health. But that’s just the point, isn’t it? Manufacturers can’t be passive, because there is nothing more vital to customers than their cardiovascular wellbeing—to improve a product is, potentially, to improve the quality of many lives, and perhaps even extend them.
