When it comes to choosing lung health supplements, you deserve more than marketing claims—you deserve evidence. That's why Betterbrand invested in clinical research to study exactly how our flagship Mullein + Chlorophyll Drops perform in real-world conditions. In this post, we're pulling back the curtain on our clinical study process, sharing what we've learned, and explaining why third-party tested supplements matter more than ever in today's crowded wellness market.

Why We Invested in Clinical Research
The supplement industry has a transparency problem. According to a 2024 ConsumerLab report, nearly one in four supplements tested failed to meet quality standards—containing either less of the active ingredient than claimed or potentially harmful contaminants. This reality frustrates consumers who are genuinely trying to support their health.
Dr. Chris Jackson, PharmD, founded Betterbrand with a different vision. As a former US Army Combat Medic and Doctor of Pharmacy, he understood that doctor-formulated supplements should be held to higher standards than the industry minimum.
"Anyone can put herbs in a capsule and make claims," Dr. Jackson explains. "We wanted to actually study what our products do for real people in their daily lives."
That commitment led us to partner with Citruslabs, an independent clinical research organization, to conduct a rigorous 60-day study on our Mullein + Chlorophyll Drops formula.
Inside Our 60-Day Clinical Study
Study Design
Our clinical trial wasn't a quick weekend survey—it was a carefully designed 60-day study conducted by Citruslabs, a third-party research organization that specializes in consumer product testing. Here's how it worked:
- Participants used Mullein + Chlorophyll Drops daily for 60 consecutive days
- Researchers collected data at multiple intervals throughout the study
- Participants reported on specific respiratory wellness markers
- All data was collected and analyzed independently by Citruslabs
The study focused on four key areas that matter most to people seeking respiratory support: coughing frequency, airway clarity, mucus clearance, and sleep quality.
Why 60 Days?
Herbal lung supplements work differently than pharmaceutical interventions. They support your body's natural processes over time rather than providing instant symptomatic relief. A 60-day timeframe allows researchers to observe meaningful trends while accounting for normal day-to-day variations in how people feel.
The Results: What the Data Shows
After 60 days of consistent use, participants in our clinical study reported significant improvements across all four measured categories:
- Coughing Frequency: 81% of participants reported less frequent coughing
- Airway Clarity: 77% reported clearer airways
- Mucus Clearance: 73% reported easier mucus clearance
- Sleep Quality: 68% reported improved sleep quality
These results align with traditional uses of mullein, which has been used in herbal medicine for centuries to support respiratory wellness. The addition of chlorophyll—a powerful antioxidant—appears to complement mullein's supportive properties.
Understanding the Numbers
It's important to note what these results mean and what they don't mean. This study measured participant-reported outcomes—how people actually felt after using the product consistently. While this type of data is valuable for understanding real-world benefits, it differs from mechanistic studies that examine exactly how ingredients work at the cellular level.
We're committed to being honest about what our research shows. The study demonstrates that the majority of users experience noticeable improvements in respiratory comfort. It does not claim to treat, cure, or prevent any disease.
What Makes Our Research Different
GMP Certified Manufacturing
Before a product can be studied, it needs to be manufactured consistently. Our GMP certified supplements are produced in facilities that meet strict quality control standards established by the FDA for dietary supplements. This means every batch contains exactly what the label says—no more, no less.
Independent Testing by Eurofins Scientific
Beyond our internal quality controls, every Betterbrand product undergoes third-party testing by Eurofins Scientific, one of the world's largest and most respected testing laboratories. When comparing BetterLungs vs competitors, this level of verification sets our products apart from brands that rely solely on self-reported quality claims.
Eurofins tests for:
- Active ingredient potency
- Heavy metal contamination
- Microbial purity
- Label accuracy
Doctor-Formulated Foundation
Having a PharmD develop our formulations isn't just a marketing point—it fundamentally changes how products are created. Dr. Jackson's pharmaceutical training means understanding drug interactions, proper dosing, and evidence-based ingredient selection. This expertise shapes everything from which ingredients we include to how we combine them.
The Importance of Third-Party Testing
If you're evaluating lung health supplements, third-party testing should be non-negotiable. Here's why:
Verification Over Trust: Any company can claim their products are pure and potent. Third-party tested supplements provide independent verification that those claims are accurate.
Contamination Detection: Herbal supplements can be contaminated with heavy metals, pesticides, or other substances during growing and processing. Independent testing catches problems that internal quality control might miss.
Consumer Confidence: When 836,000+ customers trust Betterbrand, they're trusting the verification systems behind our products, not just our marketing.
The fact that our products are sold at CVS, Walgreens, and GNC reflects the confidence major retailers have in our quality standards. These retailers conduct their own supplier verification before stocking products.
What's Next for Betterbrand Research
Our Mullein + Chlorophyll study was a starting point, not an endpoint. We're currently exploring additional research opportunities to better understand how our formulations support respiratory wellness.
Future areas of investigation include:
- Longer-term studies examining benefits over 90+ days
- Comparative studies examining our full product line
- Deeper analysis of specific populations (seasonal allergy sufferers, former smokers, etc.)
- Mechanistic research exploring how key ingredients work together
We believe the supplement industry needs more brands willing to invest in real research. It's more expensive and time-consuming than simply making claims, but it's the right thing to do for customers who trust us with their health.
Frequently Asked Questions
Who conducted Betterbrand's clinical study?
Our clinical study was conducted by Citruslabs, an independent third-party research organization specializing in consumer product trials. Citruslabs has no financial stake in our products' success, ensuring unbiased data collection and analysis.
What was studied in the clinical trial?
The 60-day study specifically examined our Mullein + Chlorophyll Drops formula. Participants reported on four key metrics: coughing frequency, airway clarity, mucus clearance, and sleep quality. The majority of participants (68-81% depending on the metric) reported improvements.
Are Betterbrand supplements FDA approved?
Dietary supplements are regulated differently than drugs in the United States—they don't receive "FDA approval" in the same way medications do. However, our products are manufactured in FDA-registered, GMP certified facilities and undergo third-party testing by Eurofins Scientific to verify quality and purity.
How do doctor-formulated supplements differ from other supplements?
Doctor-formulated supplements are developed by healthcare professionals with clinical training. Dr. Chris Jackson, PharmD, brings pharmaceutical expertise to ingredient selection, dosing, and formulation. This background helps ensure products are both effective and safe when used as directed.
Why does third-party testing matter for supplements?
Third-party testing provides independent verification that a supplement contains what the label claims and is free from contaminants. Without this verification, you're relying solely on a company's word. Our products are tested by Eurofins Scientific, one of the world's largest testing laboratories.
Conclusion
