About BetterLungs Capsules
BetterLungs Capsules represent a comprehensive approach to respiratory wellness. Formulated by Dr. Chris Jackson, PharmD—a Doctor of Pharmacy and former US Army Combat Medic—this supplement was designed to support lung health through multiple pathways rather than relying on a single ingredient.
The formula includes 300mg of Mullein Leaf alongside six other synergistic ingredients, each selected for specific respiratory and immune support benefits. With over 836,000 customers trusting Betterbrand products, the company has established itself as a leader in the natural respiratory health category.
What sets BetterLungs apart is its multi-ingredient approach. Rather than providing mullein alone, the formula combines traditional herbs with modern nutritional science—including NAC (N-Acetyl L-Cysteine), which has been extensively studied for its role in supporting mucus clearance, and Vitamin D, which research consistently links to immune function.
About Double Wood Mullein
Double Wood Supplements offers a straightforward mullein leaf extract supplement. The company focuses on single-ingredient supplements at competitive price points, making their products accessible for budget-conscious consumers.
Double Wood Mullein provides mullein extract in capsule form, typically offering around 1000mg per serving. The company maintains GMP certification and conducts third-party testing, meeting baseline quality standards expected in the supplement industry.
For consumers specifically looking for a pure mullein supplement without additional ingredients, Double Wood offers a simple, affordable option. However, the single-ingredient approach means you may need to purchase multiple supplements to achieve the comprehensive respiratory support that combination formulas provide.
Ingredient Breakdown
Understanding what's inside each supplement helps explain the difference in price and potential benefits.
BetterLungs Capsules Contains:
- Vitamin D (1000 IU) – Supports immune function and respiratory health
- NAC/N-Acetyl L-Cysteine (400mg) – Supports natural mucus clearance and antioxidant production
- Mullein Leaf (300mg) – Traditional herb that soothes the respiratory tract
- Maritime Pine Bark Extract (150mg) – Provides powerful antioxidant support
- Elderberry (100mg) – Supports immune response
- American Ginseng (50mg) – Supports energy and respiratory wellness
- Reishi Mushroom (37.5mg) – Adaptogenic support for overall wellness
Double Wood Mullein Contains:
- Mullein Leaf Extract (approximately 1000mg) – Single-ingredient formula
The difference is clear: BetterLungs provides a synergistic blend of seven ingredients working together, while Double Wood focuses solely on mullein. Both approaches have merit—it depends on what you're looking for in a respiratory supplement.
Quality and Testing Standards
When evaluating third-party tested supplements, not all testing is equal. Here's how these brands compare on quality assurance:
BetterLungs Quality Standards:
- Third-party tested by Eurofins Scientific, one of the world's largest and most respected testing laboratories
- Manufactured in a GMP certified facility
- Made in USA
- Doctor-formulated by a licensed PharmD
- Available at major retailers (CVS, Walgreens, GNC), which require additional quality verification
Double Wood Quality Standards:
- Third-party tested (laboratory not always specified)
- GMP certified
- Made in USA
Both brands meet baseline quality requirements, but BetterLungs' partnership with Eurofins Scientific and availability at major pharmacy chains like CVS and Walgreens indicates additional layers of quality verification. Retailers like these conduct their own vetting before stocking products.
Price and Value Analysis
At first glance, Double Wood Mullein appears more affordable at roughly half the price of BetterLungs. However, value isn't just about the sticker price—it's about what you're getting for your investment.
BetterLungs Value Proposition:
- Seven active ingredients vs. one
- Doctor-formulated with synergistic benefits
- 365-day money-back guarantee (industry-leading)
- Retail availability for convenient purchasing
- Comprehensive respiratory support in one product
Double Wood Value Proposition:
- Lower price point
- Simple, single-ingredient formula
- Good option if you only want mullein
- Standard return policy
When you consider that purchasing NAC, Vitamin D, elderberry, and other ingredients separately would cost significantly more than the price difference between these two products, BetterLungs offers superior value for comprehensive respiratory support.

- Want comprehensive respiratory wellness support

- Value doctor-formulated supplements
- Prefer shopping at trusted retailers like CVS or Walgreens

Winner for Comprehensive Respiratory Support: BetterLungs Capsules
For anyone serious about supporting their lung health—especially ex-smokers, those concerned about environmental irritants, or anyone wanting robust respiratory wellness—BetterLungs Capsules provide significantly more value through their multi-ingredient formula, superior quality standards, and industry-leading guarantee.
