Your body makes mucus to protect your lungs.
A thin layer of mucus coats the inside of your nose, throat and lungs. It catches dust, smoke and germs before they get in. When everything is healthy, it stays thin and you never notice it.
Over the years, smoking, pollution, allergies and colds wear down the lining that makes this mucus. To stay healthy, that lining needs an antioxidant called glutathione, and your body makes less of it as you get older.
When glutathione runs low, the mucus gets thick and sticky. That is the phlegm you cough up every morning and the gunk you keep clearing from your throat.
Sprays, rinses and Mucinex only move the mucus that is already there. They do nothing about why it keeps coming back, so it is back again the next morning.

*Orvia Labs customer survey. Sources: Stey et al., European Respiratory Journal, 2000 (11 trials). PANTHEON trial, The Lancet Respiratory Medicine, 2014 (1,006 patients, 1,200mg a day).
For decades, chronic mucus and cough were treated one symptom at a time. Thin it, dry it, suppress it. The mucus comes back because the lining that makes it never recovers.
NAC works one step earlier. It is the raw material your body uses to make glutathione, the master antioxidant that protects the lining of your airways. A calmer lining makes thinner mucus that clears on its own.
It has been studied for more than 40 years. In the PANTHEON trial, 1,006 people took 1,200mg of NAC a day for a full year and had 22% fewer flare-ups than placebo. A review of 11 trials found that 61.4% of people on NAC reported better symptoms, compared with 34.6% on placebo.
Orvia Labs Liposomal NAC delivers that same 1,200mg daily dose, wrapped in a liposome so it survives stomach acid instead of breaking down before it absorbs.

- Acetylcysteine in the treatment of subacute sinusitis: a double-blind placebo-controlled clinical trial · Ear, Nose & Throat Journal, 2017
Take 2 capsules once a day with a meal. Breakfast works well for most people.
What matters is consistency. The lining of your airways recovers gradually, so steady daily use is what builds results.
Here is what most people notice:
- Weeks 1 to 2: Less throat clearing first thing in the morning. Subtle, but you notice it.
- Weeks 3 to 4: Mucus feels thinner and clears with one swallow instead of 10 minutes at the sink.
- Weeks 5 to 8: Calmer drip, fewer coughing fits and quieter nights.
- Weeks 8 to 12 and beyond: Clear mornings become your new normal. Daily use keeps the lining stocked.
Drink plenty of water. Mucus thins faster when you are well hydrated.
One note: Orvia Labs Liposomal NAC is a supplement, not a medication. Keep using your inhaler or prescriptions as directed. If you are pregnant, nursing or on prescription medication, talk to your doctor first.

“post nasal drip since 2017 and I’ve done the whole song and dance: flonase, zyrtec, claritin, a neti pot, every lozenge in walgreens, that onion and honey thing my aunt swore by lol. Started this in feb because my dentist of all people mentioned NAC when I was clearing my throat in his chair and i went down a rabbit hole. Month 3 at this point and the drip is way down, i’m not hacking every morning, sleep is better. Couldn’t be happier with this.”

“12 years of clearing my throat every 2 minutes and I’d basically accepted that was just me now. that was my baseline. then this came along and around week 6 I caught myself singing in the car the whole way to work without stopping to clear my throat once. which I had not done in years.... This has made a world of difference and the gunk is now only really there when i have a cold and it’s been like this since month 4, and I could not be happier!! Thank you guys!!”

“For over a year I just ‘watched.’ My grandkids would beg me to play outside and I’d have to say not today. I quit smoking 9 years ago but my chest never got the memo, I’d get winded just walking to the mailbox and cough up stuff every morning. A few weeks after starting Orvia I noticed I was coughing less, breathing easier. Less careful. Less scared. One afternoon my grandson wanted to play catch in the yard and I did, for an hour. Couldn’t be more happy with this product!”

“Been singing in my church choir for like 6 years & hit a wall a while back where I just couldn’t hold a long note without the phlegm catching no matter what I did. Choir director kept saying “drink more water, warm up longer...” Ms, I was drinking water for like 2 years!! Added Orvia to my morning routine 9 weeks ago & the wall came down, it was literally the only thing I changed, and I held the whole last note of Amazing Grace sunday without clearing my throat for the first time ever. I’m feeling WAY more clear, insane results.”

“Got a nasty chest cold 3 winters ago (thanks daycare :D) and the cough has been a thing on and off ever since. Did the inhaler, did the steroid pack, did the humidifier phase, did the mullein tea phase. This is the first thing in years that’s actually calmed the mucus down instead of just temporarily covering it up. month 2 and I can sit through a movie without a coughing fit every 10 min, and sleep all night long for the first time in years.”

“I’m 58 and the morning phlegm creeping in over the last few years was making me feel like I was watching myself get old in real time. Started this in January and a couple weeks ago my sister made me laugh so hard at dinner and it didn’t turn into a coughing fit and it caught me off guard. I can breathe so much easier and the first hour of the morning isn’t spent at the sink anymore. This made all the difference for me”
Linda K,

“COPD diagnosis 2 years ago and honestly I was scared, my mom had it. My pulmonologist said NAC was worth trying alongside my inhaler so I went looking for a good one and these are the only ones that didn’t give me the sulfur burps lol. 3 months in and I bring up way less in the mornings and I got through flu season without a single flare up. I tell everyone at pulmonary rehab about it.”
The Science Behind Liposomal NAC
1
The Problem Develops
Over time, smoke, pollution, allergies and colds wear down your airway lining. It runs low on glutathione and the mucus turns thick and sticky. Instead of clearing on its own, it sits in your throat and chest. Coughing and congestion follow.
2
The Liposomal NAC Solution
Each serving delivers the full 1,200mg of NAC used in clinical trials, wrapped in a liposome so it survives your stomach and reaches your bloodstream instead of breaking down.
3
Your Lining Recovers
Your body turns NAC into glutathione and sends it to your airway lining. The irritation settles, mucus thins out, and the tiny hairs that sweep it away start working again.
4
Your Body Responds
With a calm lining and thin mucus, you clear less, cough less and breathe easier. Mornings start clear and the gunk that built up over years stops coming back.
Your Transformation Timeline
A general timeline of what to expect-individual results may vary based on severity and consistency
Phase 1
Weeks 1–2, Foundation
Building glutathione back up in the airway lining. Most people don’t feel big changes yet, and that’s normal. Some notice the first hour of the morning is a little easier.
Phase 2
Weeks 3–4, Thinner Mucus
Mucus clears with one swallow instead of ten minutes at the sink, and there’s less throat clearing on calls and at dinner.
Phase 3
Months 2–3, Clear Mornings
The drip calms down, coughing fits get rare, sleep through the night. People notice you’re not hacking or sniffling anymore.
Phase 4
Months 4–6, Lasting Defense
The lining stays stocked, colds settle in the chest less often and clear faster, and breathing easy stops being something you think about.

5 Reasons Why
Liposomal NAC Is Different From Everything You've Tried
Sprays, rinses and pills move the mucus that's already there. Liposomal NAC rebuilds the glutathione your airway lining needs, and the liposome makes sure it actually gets there.
LIPOSOMAL DELIVERYUp to 10x better absorption
Reason 1
A Shield That Survives Your Stomach
Standard NAC loses up to 90% to stomach acid before it absorbs. Ours is wrapped in a liposome, a tiny fat bubble made from sunflower lecithin, so the NAC gets through digestion intact.
1,200MGN-Acetyl L-Cysteine per serving
Reason 2
The Full Clinical Dose
1,200mg a day is the dose used in the 1-year PANTHEON trial that cut flare-ups by 22%. No underdosed blends, no proprietary mixes. Just the full amount, every day.
GLUTATHIONEYour airways' master antioxidant
Reason 3
Works On The Cause, Not The Symptom
Your body turns NAC into glutathione, the antioxidant your airway lining runs on. A calmer lining makes thinner mucus, so it stops coming back every morning.
NO SULFUR BURPSNo smell, no aftertaste
Reason 4
Gentle On Your Stomach
Ordinary NAC is known for sulfur burps and an upset stomach. The liposome keeps it sealed until it absorbs, so it's easy to take every morning with breakfast.
3RD PARTY LAB TESTEDEvery batch, in the USA
Reason 5
Clean, Tested Ingredients
Just NAC and sunflower lecithin in a vegetable capsule. Non-GMO and gluten-free, made in a GMP-certified facility, and every batch third-party tested for purity and potency.
What a 1,006-Person, 1-Year NAC Study Revealed
Most people reach for Mucinex, nasal sprays or mullein to deal with thick mucus and a morning cough. The research points somewhere else: in the largest year-long trial of its kind, 1,200mg of NAC (N-Acetyl Cysteine) a day cut flare-ups by 22%, and across 11 clinical trials nearly 2 in 3 people on NAC felt their symptoms improve.
What the Research Shows
In the PANTHEON trial, published in The Lancet Respiratory Medicine, researchers at 34 hospitals gave 1,006 people with COPD 600mg of NAC twice a day for a full year. The NAC group had 22% fewer flare-ups over the year, and it was as well tolerated as a sugar pill.
A review of 11 placebo-controlled trials and 2,011 patients in the European Respiratory Journal found the same pattern: 61.4% of people on NAC reported their symptoms improved.
Key Improvements After Rebuilding Airway Glutathione
- Thinner, Easier To Clear Mucus
- Less Morning Coughing And Throat Clearing
- Fewer Flare-Ups And Chest Colds
- Glutathione Restored, Your Airways' Master Antioxidant
- Calmer Post Nasal Drip
- Easier Breathing On Stairs And Walks
- Deeper, Uninterrupted Sleep
- More Steady Energy Through The Day
Why It Happens
The lining of your airways depends on glutathione, the body's master antioxidant, to protect itself and keep mucus thin and moving. Smoke, pollution, allergies and every cold use it up, and your body makes less of it as you get older. When it runs low, the mucus turns thick and sticky and the cough settles in.
That is why sprays, rinses and expectorants fade. They move the mucus that is already there, but none of them restore the glutathione the lining runs on, so it is back the next morning.
NAC delivers cysteine, the building block your body needs to make glutathione. Hospitals have used it since the 1960s, and it is the same compound the FDA approved as the emergency antidote for acetaminophen overdose. But standard oral NAC has just 4–9% bioavailability, so most of it never reaches your bloodstream. Liposomal delivery survives stomach acid and gets the full 1,200mg clinical dose to where it is needed.
Hear from Clinicians
“My patients come in after years of sprays, cough syrups and allergy pills. At the full 1,200mg a day, NAC is the one thing I have seen consistently thin the mucus and quiet the morning cough. Orvia Labs is the formula I point them to.”
“The airway lining runs on glutathione, and NAC is the raw material to rebuild it. PANTHEON showed what happens at 1,200mg a day: 22% fewer flare-ups over a full year. Orvia is the only formulation I recommend that delivers that dose with liposomal absorption behind it.”
“Hospitals have relied on NAC for decades. The molecule was never the question, the delivery was. Orvia's liposomal shell gets the full clinical dose past the stomach, where a dry capsule loses most of it.”

Frequently Asked Questions
Can I take this with medication?
+
Most of our customers take it alongside the prescriptions they are already on.
NAC is the nutrient your body uses to make glutathione, and hospitals have used it for over 60 years.
It does not push your glucose down the way a medication does, so there is nothing to time around a dose.
Does it help blood sugar, cholesterol or both?
+
Both, because both are controlled by the liver.
The liver releases the sugar behind your morning number, and it is also where cholesterol gets cleared out of the body.
When it runs short on glutathione, it falls behind on both jobs at once, and the stubborn weight around your middle stalls with it.
NAC gives the liver the raw material to make glutathione again, which is why customers see their sugar, cholesterol and liver numbers move together on the same panel.*
I've tried berberine, cinnamon and other supplements. Why would this be different?
+
Each of those pushes on one number.
None of them rebuilds the glutathione the liver needs, so the liver stays behind and the numbers drift back up.
NAC is the raw material the liver builds glutathione from. At the full 1,200mg dose, in a liposomal form that gets it past stomach acid, the liver finally gets back what it has been short of.*
And if your numbers do not move, the 90-day guarantee covers you.
How soon will I feel it, and when will my numbers move?
+
Weeks 1 to 2: most customers notice deeper sleep first, then the afternoon crash fades.*
Weeks 3 to 4: energy holds through the whole day, you wake up clear instead of foggy, and the evening cravings settle.*
Weeks 8 to 12: this is the window your next blood panel shows it.*
That is why the 3-bottle bundle is the most popular choice. It covers the full 90 days.
How do I know this isn't another supplement scam?
+
Fair question. This market is full of them.
Orvia Labs Liposomal NAC is made in an FDA-registered, cGMP-certified facility, and every batch is third-party tested for purity and potency.
Every ingredient and every amount is on the label, with no proprietary blends.
We sell only at orvialabs.co. Listings on Amazon or eBay using our name are not ours, and you cannot verify what is in them.
A real support team answers at support@orvialabs.co, and every order is backed by our 90-day money back guarantee.
What if it doesn't work for me?
+
You have 90 days from delivery to test it yourself.
If you do not feel the difference, or your numbers do not move, email support@orvialabs.co and we refund your order.
Less than 1% of customers ever ask for a refund.
Do I have to take it forever?
+
Your body uses up glutathione every day and makes less of it every year with age.
The support lasts as long as you keep supplying the raw material, so we recommend staying on 2 capsules a day once your numbers are where you want them. That is what holds them there.
Will it upset my stomach like other NAC?
+
The sulfur burps, cramps and rotten-egg smell come from raw NAC powder hitting your stomach.
Each dose of ours sits inside a phospholipid shell made from sunflower lecithin, so it passes through gently.
Take it with food and most customers never notice it.
How do I take it?
+
2 capsules a day with food, ideally with breakfast. That is the full 1,200mg dose.
An empty stomach is the one thing that can cause discomfort, so keep it with a meal.
One bottle lasts 30 days, and it needs no refrigeration.
What's in it?
+
1,200mg of N-acetyl cysteine per 2-capsule serving, in a liposomal complex made from sunflower lecithin.
Other ingredients: vegetable cellulose (the capsule) and rice flour.
60 capsules per bottle. Non-GMO, gluten free, vegan friendly and dairy free.
Where does it ship from, and how long does it take?
+
Every bottle ships with full tracking.
Orders leave our international warehouses within 1 to 2 business days. US orders arrive in 4 to 8 business days, and the UK, Canada, Australia and New Zealand in 7 to 14.
You get a tracking link by email the moment your order ships.
Can I take it with milk thistle or my other supplements?
+
Yes. NAC pairs well with most vitamins and supplements.
Milk thistle tells the liver to make glutathione, but it cannot supply the raw material to build it. NAC supplies that material, so the two work on different parts of the same job.

Debra M. 61
★★★★★Verified CustomerQuit smoking 6 years ago and everybody told me the cough would go away on its own. It didn't. Every morning started with 15 minutes of hacking at the kitchen sink and hardly anything coming up. My daughter sent me the link and I figured one more thing couldn't hurt. Week 3 I realized I was drinking my coffee out on the porch instead of standing at the sink. Month 2 now and the rattle in my chest is mostly gone. Already ordered 3 more.
Kevin S. 54
★★★★★Verified CustomerTried 2 other NAC brands before this. Both gave me sulfur burps all morning and my wife said my breath smelled like eggs lol. With this one I don't taste anything. And the post nasal drip at night is way down.
Tom H. 68
★★★★★Verified CustomerChronic bronchitis every winter for 10 years. Antibiotics, steroids, the whole routine every January. My wife started me on this in September and it's the first winter I can remember where I didn't end up at urgent care. I still use my inhaler and see my doctor, but this one stays in the cabinet.
Renee P. 47
★★★★★Verified Customerthe constant throat clearing is GONE. my coworkers noticed before I did. 7 weeks in.
Angela W. 52
★★★★★Verified CustomerI teach 2nd grade and by 10am I'd sound like a frog from clearing my throat all morning. Lozenges in every pocket, water bottle glued to my hand. About a month into Orvia I got through a whole read-aloud without stopping once. The kids didn't notice but I sure did 🙌
Gary F. 59
★★★★★Verified CustomerI was skeptical. I've bought a lot of supplements that did nothing. This one I could feel by week 4. Mornings are quiet now and my wife says I stopped coughing in my sleep too.
Patricia N. 64
★★★★★Verified CustomerSpring used to mean months of my head full of gunk and a drip down the back of my throat all day. I garden every morning so I can't exactly avoid the pollen. Started Orvia in March and I've been out in the beds every day this year without tissues stuffed in my pocket. Getting the 3 pack next time.
Marcus J. 45
★★★★★Verified CustomerI've been the guy who coughs through every meeting for years. Doc said post nasal drip and gave me a spray that dried me out. Read about NAC and picked this one because it's liposomal. 5 weeks in and my mornings are clear. Wish I'd found it sooner.
Carol B. 72
★★★★★Verified CustomerMy daughter ordered this for me after hearing me cough on the phone every Sunday. I have COPD and didn't expect much. 3 months later I bring up much less in the mornings and I can walk to the end of the block and back without stopping. My daughter cried when I told her. The capsules go down easy too.
Diane K. 57
★★★★★Verified CustomerI used to lie awake listening to my own chest rattle. Now I sleep through the night. That's the review.
