The four separate boxes are perfect for keeping one at my desk and one in my bag so I never miss a day. I've gone through a full cycle already and the vitamin blend feels like a solid daily buffer against the seasonal crud. No sugar crash or weird aftertaste, which is a win for me.
It’s mid-October and everyone in my office is sniffling, but I’ve been chewing these every morning and stayed clear so far. The 4×21 pack means I’ve got a full season’s worth, and I love that they’re sugar-free so they don’t wreck my teeth.
