*Based on a customer survey among RS-01® users, 2025/26
Airway Opening
Lobelia relaxes constricted airways so breathing requires less effort from the very first days.
Cellular Defense
NAC rebuilds glutathione, the cellular antioxidant COPD depletes. Stopping oxidative damage from continuing between doses.
Inflammation Suppressed
Quercetin shuts down the NF-kB cascade driving airway wall thickening every day. The slow fire inhalers never reach.
Bacterial Defense
Thyme and oregano oil target the bacterial cycle turning damaged airways into repeated infections and exacerbations.
Airways Open
The tightness that made every breath feel like work starts to release. Airways that were constricted begin to open.
Inflammation Quiets
The persistent fire in your airway walls starts to settle. Less daily constriction. The chest stops feeling constantly irritated.
Defense Rebuilds
The cellular protection your airways lost starts coming back. The damage cycle begins to slow. Flare-ups become less frequent.
Breathing Resets
Airways settle into a cleaner baseline. Breathing becomes something that just happens again. Not something you manage.

Inhalers manage airflow for hours. They don't address what keeps driving the problem. Three things are actively working in COPD airways that treatment never reaches: chronic inflammation thickening the walls, oxidative stress depleting cellular defenses, and a bacterial cycle driving exacerbations. RS-01® targets all three: Quercetin suppresses the inflammatory cascade. NAC rebuilds the antioxidant defense COPD depletes. Thyme and oregano clear the bacterial environment. Lobelia opens the airway first. All sublingual — 60 seconds to your airways.

How does a dropper support my lungs?
Capsules dissolve in your stomach. Most of the active compounds never reach your airways. A sublingual dropper absorbs through the tissue under your tongue and reaches your airways in around 60 seconds — bypassing digestion entirely. That is the difference between something sitting in your gut and something working where the problem actually is.
What makes RS-01® different from basic mullein drops?
Basic mullein loosens surface mucus — one action. RS-01® addresses the three biological processes driving COPD decline: chronic inflammation thickening airway walls, oxidative stress depleting cellular defenses, and a bacterial cycle driving exacerbations. No basic mullein product addresses any of that.
How long before I notice a difference?
Most people notice airways feeling less restricted within the first 1-2 weeks. Anti-inflammatory and cellular defense support builds over 4-6 weeks of consistent daily use.
Can I use this alongside other supplements or medications?
Yes. RS-01® complements your COPD protocol — addressing the biological root causes inhalers don't reach, not replacing them. Most customers use it alongside their existing routine without any issues. Check with your doctor first if on COPD medication.
What if it does not work for me?
90-day full refund. No questions, no conditions.
Every Ingredient Carefully Chosen
Every ingredient in this formula is there because it addresses a specific stage of the clearing process. Not a proprietary blend. Not a vague label. A transparent, clinically-referenced seven-compound formula.
Mullein Leaf Extract
Loosens & Clears Mucus
Loosens and breaks up congestion so your body can start clearing it out naturally. The most trusted herb for lung support, and the backbone of this formula.
NAC (N-Acetyl Cysteine)
Breaks Down Deep Mucus
Breaks down thick, stubborn mucus that basic herbs alone cannot reach. Used by doctors to help clear the lungs. Targets the deeper buildup that keeps people congested long-term.
Lobelia Extract
Opens & Relaxes Airways
Opens and relaxes the airways so breathing feels less tight. Works before the clearing starts, making everything else in the formula more effective.
Thyme Extract
Sweeps Airways Clean
Helps restart your airways' natural self-cleaning process, which pushes out trapped mucus and debris. Approved in Europe specifically for bronchial mucus clearance.
Quercetin
Calms Airway Inflammation
Calms the underlying inflammation that keeps airways irritated and tight. Helps reduce the root reaction that causes congestion to keep coming back, not just mask it.
Peppermint Oil
Airway Comfort
Creates an immediate feeling of open, easier breathing from the very first use. Helps soothe the airways and makes each breath feel cleaner and less restricted.

Hold for 60 Seconds
Enters your bloodstream in 60 seconds — reaches your airways directly
Morning or Evening

Deeper clearing and airway support build over time
What Real Customers Are Saying
Linda S., 68
|Phoenix, AZ"I didn't realize how much breathing was taking up space in my head until it stopped."
Six weeks in and the thing I notice most is how unremarkable mornings have become. There used to be fifteen minutes of clearing before I could start anything. That process is gone. I am 68 and breathing has not felt this easy since my forties.
James R., 51
|Denver, CO"First time in years I made it up two flights of stairs without thinking about it."
I was diagnosed with COPD about four years ago. Over the following years I managed with inhalers and slowly stopped doing things I used to do without thinking about it. Since starting RS-01®, I am massively better. The morning congestion I had lived with for years started clearing in under two weeks. Last month I walked three flights at the airport and did not stop once. That has not happened in over six years. I cannot believe how much has changed. I want to tell everyone.
Carol B., 62
|Portland, OR"Thyme tea, mullein drops, and a peppermint rub. This replaced all three."
Years of assembling something every morning before I could feel normal. Eight weeks with this and my morning routine is two droppers and done. Breathing holds better through the whole day. The congestion that used to define my mornings by 10am is not what it was. I am 62 and I finally have one thing that works.

Before You Try It
Why Ignoring Your Lung Health
Isn't Optional Anymore
COPD is the third leading cause of death globally. Most people wait years before acting on worsening breathing. The ones who act early are the ones who still have options.
People worldwide living with COPD — most undiagnosed
Of acute COPD exacerbations are bacterial in origin — most are never directly treated

Between the fan, the AC, and the cooling mattress pad, I'd spent over a thousand dollars trying to solve this. My body just heats everything up. This is the first thing I've tried that actually works from the inside.
Barbara M.
I would wake up at 2am burning. Wait an hour to cool down. Try to fall back asleep. Every single night. This broke that cycle. The 2am wake-up barely happens anymore.
Karen M.
My husband said I was like a space heater in bed. He was sleeping on the edge to stay cool. Three weeks of taking this before bed and he's moved back to his side of the bed. That tells me more than anything else.
Carol T.
Tried melatonin. Tried magnesium. Both helped me feel calm but did nothing for the actual heat. Glycine is the first thing I've tried that was specifically targeting the temperature problem and you can actually feel the difference in how you wake up.
Steven R.
I'm perimenopausal and the hot flashes at night were already bad. Adding glycine didn't cure the hot flashes but it changed how I slept through them. Less lying awake waiting. More actual sleep.
Linda P.
I read the research before ordering. The published studies on glycine and core body temperature reduction were what sold me. 3,000mg matches the dose used in the trials. That specificity matters when you've already wasted money on products with no real evidence behind them.
