Why Lung Health Matters More Than Ever in 2026
Our respiratory system faces more challenges today than at any point in recent history. According to the American Lung Association, approximately 34 million Americans live with chronic lung disease, and air quality concerns continue to affect communities nationwide. The World Health Organization reports that 99% of the global population breathes air that exceeds WHO guideline limits for pollutants.
Beyond environmental factors, lifestyle choices continue to impact respiratory wellness. While smoking rates have declined, vaping has introduced new concerns, particularly among younger populations. The Centers for Disease Control and Prevention notes that former smokers—nearly 31 million Americans—often seek ways to support their lung recovery journey.
The good news? Research into natural compounds that support respiratory health has advanced significantly. We now have better clinical data on traditional remedies and a clearer understanding of how certain nutrients support lung function at the cellular level.

The 10 Best Supplements for Respiratory Wellness
- Mullein Leaf Extract — Best Overall for Respiratory Support
Mullein (Verbascum thapsus) tops our list as the most versatile and effective herb for respiratory wellness. Used for centuries in traditional European and Native American medicine, mullein has earned its reputation as the go-to herb for lung support.
Why it works: Mullein contains saponins and mucilage compounds that help soothe the respiratory tract and support natural mucus clearance. Research published in the Journal of Ethnopharmacology has documented mullein's traditional use for respiratory complaints, while modern studies suggest it may help maintain clear airways.
The mullein benefits extend beyond simple respiratory support. The plant's natural compounds demonstrate antioxidant properties that help protect respiratory tissues from oxidative stress. Its gentle action makes it suitable for daily use, and unlike some respiratory herbs, it doesn't cause drowsiness or interact with most medications.
Best form: Look for mullein for lungs support in concentrated extract forms. Tinctures and drops offer faster absorption than capsules, while gummies provide a convenient alternative for those who dislike swallowing pills.
Best for: Anyone seeking daily respiratory support, particularly those wanting to clear airways naturally.
- NAC (N-Acetyl L-Cysteine) — Best for Mucus Support
NAC supplement options have gained significant attention in respiratory health circles, and for good reason. This amino acid derivative serves as a precursor to glutathione, one of the body's most important antioxidants.
Why it works: NAC helps break down mucus by disrupting the disulfide bonds that give mucus its thick, sticky consistency. A comprehensive review in the European Respiratory Journal found that NAC supplementation supports respiratory comfort and helps maintain normal mucus viscosity.
The compound also supports the body's natural antioxidant defenses. Since the lungs are constantly exposed to environmental stressors, maintaining robust antioxidant levels is crucial for respiratory wellness.
Dosage considerations: Most studies showing benefits used doses between 400-600mg daily. Higher doses should be discussed with a healthcare provider.
Best for: Individuals dealing with excess mucus, smokers and former smokers, and those wanting antioxidant support for lungs.
- Mullein + Chlorophyll Combination — Best Clinically-Studied Option
While individual ingredients show promise, the mullein chlorophyll drops combination has emerged as a particularly effective pairing, backed by clinical research.
Why it works: In a 60-day clinical trial conducted by Citruslabs, participants using this combination reported impressive results:
- 81% reported less frequent coughing
- 77% reported clearer airways
- 73% reported easier mucus clearance
- 68% reported improved sleep quality
Chlorophyll, the green pigment in plants, adds its own benefits. Research suggests it supports cellular health and may help neutralize environmental toxins. When combined with mullein's respiratory-soothing properties, the two create a synergistic effect.
Best for: Those seeking a clinically-studied option with documented results, particularly people dealing with frequent coughs or mucus concerns.
- Pine Bark Extract — Best Antioxidant for Respiratory Tissues
Pine bark extract, particularly maritime pine bark (Pycnogenol®), ranks among the most potent natural antioxidants for lungs available today.
Why it works: Pine bark contains oligomeric proanthocyanidins (OPCs)—powerful antioxidants that demonstrate exceptional bioavailability. Studies published in Phytotherapy Research show that pine bark extract supports healthy inflammatory response and helps protect tissues from oxidative damage.
For respiratory health specifically, pine bark's antioxidant properties help protect the delicate lung tissues from environmental stressors. This makes it particularly valuable for people living in urban areas or those exposed to air quality challenges.
Best for: Urban dwellers, those concerned about environmental exposure, and anyone wanting comprehensive antioxidant protection.
- Elderberry — Best for Immune-Respiratory Connection
Elderberry immune support has become mainstream, but its respiratory benefits deserve special attention. This deep purple berry has been used for centuries to support both immune function and respiratory wellness.
Why it works: Elderberry is rich in anthocyanins and flavonoids that support immune system function. A meta-analysis published in Complementary Therapies in Medicine found that elderberry supplementation significantly reduced the duration and severity of upper respiratory symptoms.
The immune-respiratory connection is important because a well-functioning immune system is essential for respiratory health. Elderberry supports this connection while providing additional antioxidant benefits.
Best for: Seasonal wellness support, immune function maintenance, and overall respiratory wellness during challenging times.
- Vitamin D — Best for Overall Respiratory Function
Vitamin D deficiency affects an estimated 42% of American adults, according to research published in Nutrition Research. This "sunshine vitamin" plays crucial roles in respiratory health that many people overlook.
Why it works: Vitamin D receptors are present throughout the respiratory tract, and the vitamin supports immune function in the lungs. Research in The Lancet Respiratory Medicine suggests that vitamin D supplementation may support respiratory wellness, particularly in those with low baseline levels.
The vitamin also supports the production of antimicrobial peptides that help maintain a healthy respiratory environment. This makes it a foundational supplement for anyone concerned about lung health.
Dosage considerations: Most experts recommend 1000-2000 IU daily, though individual needs vary. Testing your vitamin D levels can help determine optimal dosing.
Best for: Nearly everyone, especially those with limited sun exposure, darker skin tones, or living in northern climates.
- Reishi Mushroom — Best Adaptogenic Support
Reishi (Ganoderma lucidum) has been called the "mushroom of immortality" in traditional Chinese medicine. Modern research is validating many of its traditional uses for respiratory support.
Why it works: Reishi contains beta-glucans and triterpenes that support immune function and may help the body adapt to respiratory stressors. Studies in the International Journal of Medicinal Mushrooms document reishi's ability to support respiratory wellness and immune balance.
As an adaptogen, reishi helps the body respond to various stressors—including environmental ones that challenge respiratory function. Its calming properties also support the relaxation necessary for optimal breathing.
Best for: Those seeking adaptogenic support, stress-related respiratory concerns, and immune system balance.
- American Ginseng — Best for Energy and Respiratory Vitality
American ginseng (Panax quinquefolius) differs from its Asian cousin in important ways, particularly for respiratory applications. It's considered more "cooling" and gentle, making it ideal for long-term respiratory support.
Why it works: Ginsenosides, the active compounds in ginseng, support immune function and help the body manage stress. Research published in Phytomedicine found that American ginseng supplementation supported respiratory wellness during challenging seasons.
Beyond immune support, American ginseng helps maintain energy levels—important for anyone whose respiratory challenges affect their daily activities.
Best for: Those seeking energy support alongside respiratory benefits, and individuals who want gentle, long-term supplementation.
- Thyme — Best Traditional Herb for Respiratory Comfort
Thyme (Thymus vulgaris) has been used for respiratory support since ancient Greece. Modern research confirms what traditional healers knew centuries ago.
Why it works: Thyme contains thymol and other compounds that support respiratory comfort. The German Commission E (Germany's regulatory agency for herbs) has approved thyme for respiratory support based on its long history of safe, effective use.
Studies in Drug Research found that thyme extract, particularly when combined with other herbs, supports respiratory comfort and normal mucus production.
Best for: Those who prefer traditional herbal approaches, people seeking respiratory comfort, and those who enjoy thyme in teas or combined formulas.
- Quercetin — Best for Seasonal Respiratory Challenges
Quercetin, a flavonoid found in apples, onions, and other plants, has emerged as a powerful tool for seasonal respiratory support.
Why it works: Quercetin helps stabilize cells that release histamine, supporting a balanced response to environmental triggers. Research in Nutrients demonstrates quercetin's ability to support respiratory comfort during seasonal challenges.
The compound also provides significant antioxidant benefits, adding to its respiratory support profile. It works particularly well when combined with vitamin C, which enhances its absorption.
Best for: Those dealing with seasonal respiratory challenges, people wanting natural support for environmental sensitivities, and anyone seeking additional antioxidant protection.
