- 01NACLimited80% match
N-acetylcysteine thins mucus by breaking disulfide bonds in mucoproteins and supports glutathione, which may improve sinus drainage.
SuggestedN-acetylcysteine, 600 mg once or twice daily - 02QuercetinLimited74% match
Quercetin is a flavonoid that may stabilize mast cells and reduce histamine release, potentially easing allergy-driven nasal congestion.
SuggestedQuercetin, about 500 mg once or twice daily, sometimes combined with bromelain or vitamin C - 03BromelainLimited68% match
Bromelain has proteolytic and anti-inflammatory properties that some small studies suggest may reduce sinus inflammation, though evidence is limited.
SuggestedEnteric-coated bromelain, about 500 mg between meals - 04Vitamin D3Limited62% match
Vitamin D modulates immune and mucosal function, and low status is associated with chronic rhinosinusitis in observational data, though causation is unproven.
SuggestedVitamin D3, 1000 to 2000 IU daily with a fatty meal, dosed to a tested blood level - 05Vitamin CLimited57% match
Vitamin C is an antioxidant that may have a mild antihistamine-like effect, but its benefit for nasal congestion is not well established.
