How to take this pair: Take 500-1,000 mg quercetin on a relatively empty stomach or 20 minutes before meals for best absorption. Take 500-1,000 mg vitamin C at the same time to maximize the recycling effect. Bromelain taken alongside quercetin can further improve its absorption. For chronic use, take daily. During acute allergy attacks, dosing can be increased to 2-3 times daily.
