The immune-support supplements aisle has never been more crowded. Every big-time supplements company has reformulated or developed anew an immunity supplement. What makes this one stand out from the crowd is it’s designed to kick-start one’s immunity—immune cells are activated within only two hours—and then it’s to be used for only a week or so. That’s a powerful message—don’t take this forever, just when you really, really need it. It contains a veritable kitchen sink of immune-support ingredients—PureWay-C is absorbed faster and retained longer than regular vitamin C and is mostly responsible for that quick jolt of immune cells. There’s also EpiCor, a clinically validated branded ingredient that got its start from a company whose HR department noted everyone working with it got sick way less often than those in the company who didn’t. Then the product provides classic immune support from elderberry, herbals, prebiotics, probiotics, vitamin D3 and zinc.
