- Curcumin (Turmeric Extract): Widely researched for its potent natural antioxidant and anti-inflammatory pathways. A study in the Journal of Clinical Medicine notes curcumin's role in modulating inflammatory markers that affect upper respiratory tissues.
- Elderberry (Sambucus nigra): Historically utilized for immune support. Clinical studies suggest elderberry can shorten the duration and severity of respiratory challenges by supporting cellular immune responses.
