Pure NAC - Richvell™ Capsules give you N-Acetyl Cysteine (600mg) in two daily capsules, one with breakfast and one with dinner, the full 1,200mg daily amount used in the lung studies.

Hospitals have used NAC to thin thick mucus since the 1960s. The official U.S. drug label says it makes mucus less thick.† More than 15,000 published studies have looked at NAC.

†One ingredient doing one job: 60 years of hospital use on one side, modern clinical research on the other.

Made with a manufacturing method that keeps 99.98% purity, vs the industry standard 70%. The dose and the quality are better than multi-ingredient supplements, and taking NAC with another ingredient in the same capsule might lower its effectiveness. No proprietary blends, no powder taste, just results you can feel.

If phlegm has been stuck in your throat for years, if you clear your throat before every sentence, or you're tired of pills, sprays and gadgets that promise the world and deliver nothing, Richvell™ was made for you. When phlegm turns thick and sticky, it gets stuck in your throat like a golf ball.†

NAC is the compound that thins that thick phlegm, a clinically-studied ingredient examined for its effects on thick mucus, clear airways, and antioxidant activity.†

One capsule at breakfast, one at dinner, working for you every day.

  • Helps keep phlegm thin and moving†
  • Supports a clear throat†
  • Supports healthy mucus flow†
  • Supports clear airways†
  • Helps to remove phlegm†
  • Promotes easier mornings†
  • Provides powerful antioxidant protection†
  • Easy-to-swallow capsules, no powder taste
  • One pure ingredient at the studied dose, no proprietary blends

Take 2 capsules daily one with breakfast and one with dinner, with water. Keep taking it on the good days too.

The lung studies ran for a full year, so give it time.

Yes! All Richvell™ orders are backed by our 30-day money-back guarantee.

1 Clinically-Studied Compound For Thick, Sticky Phlegm

N-Acetyl Cysteine (NAC)

N-Acetyl Cysteine (NAC)

The compound Swiss hospitals have used since the 1960s to thin thick mucus, with 600mg per capsule and 1,200mg per day, the amount used in the 1-year lung studies. Backed by 15,000+ published studies.†

Thick Phlegm

Thick Phlegm

Dry air from the AC or heater, dust, smoke, allergies and every cold can create chronic thick phlegm in your throat. Once it becomes too thick to swallow, you experience symptoms like snoring, constant coughing or bad breath. NAC helps you to remove the phlegm once and for all.†

Your Throat

Your Throat

Once the thick phlegm thins out then you'll finally be able to swallow normally again without that "golf ball" feeling in your throat. You will be able to sleep without snoring, and wake up feeling refreshed.†

The morning throat clearing finally quieted down
Every morning I’d stand at the sink hacking for ten minutes before I could talk to anyone. About two weeks in, I noticed I was just brushing my teeth and walking out. I still get a little on cold days, but nothing like before.

My wife noticed before I did
She asked why I stopped making “that noise” at dinner. I didn’t even realize I’d been clearing my throat between bites for years. Week three now. Two capsules with breakfast, that’s it.

Slow start, worth sticking with
The first week I felt nothing and almost cancelled. Glad I didn’t. By day ten the drip down the back of my throat at night was lighter and I wasn’t waking up to cough. One star off only because the capsules are on the bigger side.

5 Reasons Why

Richvell™ is Different From Everything You’ve Tried

5 Reasons Why People With Stubborn Phlegm Choose Richvell™

Real results. Clean formulas. Zero compromise.
Oil Bottles
Reason 1

The Study Dose, Not Watered Down

No trendy blends or sprinkled-in ingredients. 600mg of N-Acetyl Cysteine per capsule, two a day, the exact 1,200mg used in the 1-year lung studies, backed by 15,000+ published studies on NAC alone.

Women running
Reason 2

Works On The Phlegm Itself

Why keep drying yourself out? Allergy pills dry the phlegm, steroid sprays stay in your nose, and rinse bottles and humidifiers can't thin it. In a study of 378 people with a chest cold, the usual mucus pill left phlegm just as thick as a sugar pill. Richvell™ gives you NAC, the compound that thins thick, sticky phlegm.†

Reason 3

One Pure Ingredient

The dose and the quality are better than multi-ingredient supplements, and taking NAC with another ingredient in the same capsule might lower its effectiveness. Gentle capsules, no sulfur taste, nothing to mix.

Reason 4

99.98% Purity vs. The Industry Standard 70%

It comes down to the manufacturing method behind Richvell™. And where most NAC bottles say one capsule a day, you get 600mg twice a day, the way the lung studies did it, so it keeps working morning and night.

Girl running
Reason 5

Built for Every Single Day

Hospitals have used NAC to thin thick mucus since the 1960s. Richvell™ brings it to your kitchen table in one simple capsule, built for every day, not just the bad ones.†

Back to hitting my notes in choir

I sing alto on Sundays. That sticky film made my voice crack on every high part. Our director actually asked what changed. I told her a little bottle from Richvell.

Tissue box lasts a lot longer now

I used to keep a box in the truck, one on the nightstand, one at my desk. Now I just need the nightstand one. Not a miracle, just steady.

Easy to take, no aftertaste

I’ve tried powders that tasted like rotten eggs. These are plain capsules: no smell, no burping. Two with my coffee and I forget about them.

Good product, delivery took a week

It arrived in seven days, which was fine once it got here. What I care about: mornings are easier, there’s less gunk, and my voice sounds clearer on work calls. Would give five if shipping were faster.

ROBERT A., 63, MICHIGAN · VERIFIED CUSTOMER

Teacher here, my voice thanks you

Talking to 28 fifth graders all day with phlegm sitting in your throat is exhausting. A month in, I’m not reaching for my water bottle every two minutes anymore.

Quit smoking 9 years ago, my throat never got the memo

Ever since I quit I’ve had heavy stuff every morning. My doctor said it was nothing serious, just annoying. This made it noticeably thinner and easier to clear. It’s the first thing in years that made a difference for me.

The refill is the best part

I’m terrible at reordering anything. The automatic refill shows up right when I’m down to my last few capsules. One less thing to think about.

Sleeping through the night again

That 2am tickle used to wake me up coughing, and then I’d lie awake for an hour. Since starting these, most nights I sleep straight to six. My husband is happy too.

Skeptic, mostly convinced

I don’t believe supplement hype. I bought one bottle to prove my sister wrong. Three weeks later I’m clearing my throat less, and that swallowing-glue feeling is mostly gone. I’m not sure it’s for everyone, but it worked for me.

Got the Buy 2 Get 1, glad I did

My grandkids stopped asking if I’m sick

They’d hear me hacking and ask if Grandpa had a cold. I didn’t. Something was just always stuck in there. Much better now, a month in.

Dry climate, thick mucus, finally some relief

Out here the air is so dry that everything turns to paste in the back of my throat. These plus a humidifier have made a real difference. Waking up is so much easier.

Works, just be patient

It took about two weeks for me. If you expect overnight results, this isn’t that. Once it kicked in, the constant urge to clear my throat faded.

One ingredient, that’s what sold me

I take enough pills already. I wanted one thing, not a blend of twelve I can’t pronounce. It does exactly what I bought it for.

Every autumn my drip gets worse. This year I started two weeks early, and it’s been my calmest October in a long time.

Customer service was great too

I had a question about taking it alongside my blood pressure medication. They answered the same day and told me to check with my doctor, which I did. Two months in, my throat feels clear most days.

Wish I’d found it years ago

I’ve had that lump-of-phlegm feeling for as long as I can remember. My daughter ordered this for me. I’m on my second bottle, and I can finally talk on the phone without stopping to clear my throat.
