Overview
Designs for Health combines vitamin C, quercetin, citrus bioflavonoids and zinc into one 90-capsule formula aimed at immune support and absorption.
Pairing quercetin with vitamin C is a common formulation choice, since some research suggests quercetin may support vitamin C's activity, and adding zinc rounds out a fairly standard immune-support stack rather than relying on vitamin C alone.
