Vitamin D plays a critical role in respiratory immunity. Deficiency is associated with increased respiratory infection risk and worse outcomes from pneumonia and influenza. It is not in Lungora’s formula.
Vitamin D activates antimicrobial peptides (cathelicidins and defensins) in respiratory epithelial cells. These proteins are your airway’s first-line defense against invading pathogens.
An estimated 42% of American adults are vitamin D deficient. Risk increases with age, darker skin pigmentation, limited sun exposure and obesity. Many adults over 50 need supplementation (1,000 to 2,000 IU daily).
Get your vitamin D level tested (25-hydroxy vitamin D blood test). Supplement separately if deficient. Lungora focuses on antioxidant, circulation and mineral support — vitamin D is better addressed as a dedicated supplement with a known, tested dose.
