The pair format
Two nutrients that work as one capsule
A pair formula is deliberately short. It does not try to replace a daily multivitamin; it adds one specific thing to a routine that already has general coverage. Because the ingredient list is only two lines long, the label is unusually readable — which is exactly why pairs are a good place to learn how to compare products.
