Relevance reflects how directly each supplement targets this symptom in the NutriStack map. Evidence is the supplement’s own rating. Open any name for the full profile.
- 01Vitamin D3Moderate78% match
Vitamin D modulates airway immunity and inflammation, and correcting deficiency is associated with fewer asthma exacerbations in several trials.
SuggestedVitamin D3, 1000 to 2000 IU daily with a fatty meal, dosed to a tested level - 02Magnesium GlycinateLimited68% match
Magnesium can relax bronchial smooth muscle (intravenous magnesium is used in acute attacks), and oral adequacy may support airway tone, though oral evidence is weaker.
SuggestedMagnesium glycinate, 200 to 400 mg elemental magnesium daily - 03Fish OilLimited62% match
Omega-3 fatty acids may reduce airway inflammatory mediators, though clinical trials in asthma show mixed and modest results.
SuggestedTriglyceride-form fish oil, about 1 to 2 g combined EPA plus DHA daily - 04QuercetinLimited60% match
Quercetin may stabilize mast cells and reduce histamine and inflammatory release relevant to allergic airway responses.
SuggestedQuercetin, about 500 mg once or twice daily, often taken with vitamin C - 05Vitamin CLimited57% match
Vitamin C is an antioxidant that may blunt exercise-induced bronchoconstriction in some individuals and supports airway antioxidant defenses.
SuggestedAscorbic acid, about 500 mg daily, with an extra dose before exercise if exercise triggers symptoms - 06NACLimited55% match
N-acetylcysteine thins airway mucus and replenishes glutathione, which may help mucus clearance in obstructive airway conditions.
SuggestedN-acetylcysteine, 600 mg once or twice daily
