Overview

Respiratory health is shaped by environmental exposures, immune function, and the integrity of the mucosal lining of the airways. Double Wood's respiratory health collection includes proteolytic enzymes, antioxidants, and botanical extracts that support airway clearance, reduce oxidative burden in lung tissue, and reinforce the mucosal immune barrier. All products are single-ingredient and third-party tested, making them suitable for individuals looking to complement a pulmonologist's recommendations or support everyday lung wellness.

What To Look For

Key ingredients in this category address respiratory health through different mechanisms. Serrapeptase is a proteolytic enzyme with mucolytic and fibrinolytic properties, studied for airway clearance and sinus health. NAC (N-Acetyl Cysteine) is one of the most established respiratory supplements — it is the precursor to glutathione and also directly thins mucus secretions. Magnesium Chloride supports bronchial smooth muscle relaxation. Mullein Leaf has a long traditional use in lung health and is studied for its expectorant and soothing properties. Apigenin and Luteolin are flavonoids with anti-inflammatory effects relevant to airway health. Tiger Milk Mushroom is an emerging ingredient with clinical research specifically focused on respiratory support and immune function.

Frequently Asked Questions

What supplements are good for lung health?
NAC and Serrapeptase are the two most evidence-backed options for active respiratory support. NAC is both a mucolytic and a glutathione precursor, making it relevant for airway clearance and antioxidant protection in lung tissue. Serrapeptase has been studied for reducing mucus viscosity and supporting sinus health. Mullein Leaf and Tiger Milk Mushroom are traditional and emerging options, respectively, for general lung wellness. They can be paired for broader coverage.
What is Serrapeptase and how does it help with respiratory health?
Serrapeptase is a proteolytic enzyme originally isolated from the digestive tract of silkworms. It breaks down non-living proteins, including excess mucus and fibrin. In the context of respiratory health, it is studied for reducing mucus viscosity, supporting sinus drainage, and reducing inflammatory proteins in airway tissue. It should be taken on an empty stomach for best results.
Is NAC safe for long-term use?
NAC has a well-established safety profile and is used in clinical settings (including as a standard of care for acetaminophen overdose and in some respiratory conditions). For general supplementation, most research on daily use spans 3-6 months without adverse effects. As with any supplement, it is advisable to cycle periodically and consult a healthcare provider if you have underlying lung or liver conditions.
