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.

Pros and cons

Performance notes
Citrus bioflavonoids are included alongside the vitamin C to support its stability and absorption, which is the formulation logic behind combining these ingredients rather than dosing vitamin C on its own.
