7 reasons the mucus in your throat keeps coming back after you eat

If you've tried allergy tablets, nasal sprays, lozenges and tea with honey, and you're still clearing your throat, you didn't do anything wrong. They were all aimed at the top of the problem.

7 minute read

A woman in her sixties at a family dinner holds a napkin to her mouth as she clears her throat, while her husband and daughter keep eating.

If you've had mucus in your throat for a while, you know how the day goes. You clear it before you can say good morning, you keep water and cough drops close, and after dinner it's back again.

In August and September, we asked nearly 1,400 RootSource customers to tell us about it in their own words: what it was like, how long they'd had it and what they'd tried that let them down.

Maybe you were told it's allergies, or something you'll just have to live with.

These 7 reasons explain why it keeps coming back, even after everything you've tried.

  1. Allergy tablets were made for allergies

    Older hands pressing a small white tablet out of a blister pack on a kitchen counter, next to a glass of water and a box of tissues.

    A lot of people are told the mucus is an allergy. When we asked what had let people down before, almost 1 in 5 of those who listed something had taken allergy tablets. A few had even had allergy shots.

    Allergy tablets calm the reaction your body has to things like pollen, dust and pet hair. If an allergy were behind the mucus, you'd expect the tablets to have settled it by now. For the people who listed them, they hadn't.

    "I have constant mucus that cause issues. It's super thick and drives me crazy. I have tried everything thinking it was allergies."

  2. Sprays and rinses work on your nose

    Two plain nasal spray bottles and a neti pot on a bathroom shelf in morning light.

    Nasal sprays and rinses were close behind, at 1 in 6. They're made for the nose and sinuses, on the idea that the mucus is dripping down from there.

    Plenty of people find their nose clears and their throat doesn't. Six of the people we asked had even had surgery on their sinuses, and the problem was still there.

    "Mucus collection at the back of my throat that won't clear"

    Survey respondent
  3. Lozenges, tea and honey only last while they're in your throat

    A mug of tea, a jar of honey and a small dish of cough drops on a side table next to an armchair.

    About 1 in 5 had tried cough drops, lozenges, tea, honey or another home remedy. They feel good on a sticky throat, and there's nothing wrong with any of them.

    They only work while they're there, though. Your throat keeps making mucus, so once they wear off, it's back.

    "The constant clearing of my throat leaves it sore. I suck on lozenges, mints or anything else I can get a hold of. Hot tea or other beverages only work while I using them."

    Survey respondent
  4. The mucus is your throat protecting itself

    Your throat makes mucus when something irritates it. It's a defense, the same way your eyes water in a smoky room.

    So clearing it or drying it up only deals with the mucus that's already there. As long as something keeps irritating your throat, it keeps making more.

    That's why nothing so far has lasted.

    Each of those things works on the mucus. None of them does anything about what's irritating your throat.

  5. What irritates it often comes up from the stomach

    After you eat, your stomach makes acid and an enzyme called pepsin to break your food down.

    When some of that pushes back up into your throat, even a little, your throat does what it always does and makes mucus to protect itself.

    After a meal, some of what's in your stomach can push back up toward your throat.

    That's why the mucus so often shows up after a meal, and why it's waiting for you in the morning after a night lying flat.

    The people we asked had noticed the same pattern. More than 100 of them brought up mornings, meals or night-time without being asked.

    "Constant coughing especially after meals and laying down"

    Survey respondent
  6. You don't need heartburn for this to happen

    A woman in her sixties sits in her parked car after an appointment, holding her keys and looking out of the windshield.

    A lot of people rule this out because they never get heartburn. When we asked what was going on, fewer than 1 in 10 mentioned heartburn or reflux. Most described their throat.

    What comes up can reach your throat without any burn in your chest on the way, so reflux is the last thing anyone thinks of. The tests go looking in your nose, your sinuses and your throat instead.

    Nearly 1 in 5 of the people who listed what had let them down had already seen a doctor, an ENT or an allergist, or taken something on prescription.

    "I have tried everything! Allergist,ENT and a throat specialist."

    Survey respondent
  7. Acid tablets and cutting out coffee only change part of it

    A plain dinner of grilled chicken, rice and green beans, with a slice of chocolate cake and a cup of coffee pushed away to the edge of the table.

    Acid tablets came up more than anything else when we asked what had let people down. Nearly 4 in 10 of those who listed something had taken them.

    They lower the acid, which is what they're made to do. What comes up after a meal still comes up.

    Cutting out certain foods and drinks was the most common change people had made. Of those who told us what they'd stopped or started avoiding, almost 4 in 10 had given up dairy, spicy food, coffee, alcohol or something else they liked. But you still have to eat, and every meal starts the same process again.

    Some habits do help. Smaller dinners, finishing your last meal 3 hours before bed and raising the head of your bed a few inches are all worth keeping. None of them changes what happens in your stomach after you eat.

    "I stopped drinking coffee but it didn't help"

What these people tried next, and why it might work for you

Most of what people try works on the nose, the throat or the acid. Everyone in our survey had just ordered something that works lower down, in your stomach, after you eat.

It's GR-9, a daily capsule we make. More than 15,800 people have ordered it since February.

Why would a capsule help my throat?

One person asked us exactly that: "I do question how a capsule can work on the esophagus?" It's a fair question.

GR-9 is 2 capsules a day made from brown seaweed, licorice root, ginger and zinc. The seaweed forms a natural layer on top of your meal that helps keep it down, so your throat can stay calm.*

The seaweed in GR-9 forms a natural layer on top of your meal.*

The licorice, ginger and zinc support your stomach, your throat lining and your digestion.*

It adds to what you're already doing. Keep taking anything your doctor prescribed, and ask them if you're not sure.

What they want back

We also asked what would feel different in their everyday life if things went the way they hoped. About 4 in 10 answers were about talking, singing or being around other people.

Singing came up again and again. More than 50 people named it when we asked what they'd stopped doing or started avoiding, from church choirs to karaoke.

  • Get my life back without being asked what's wrong with me
  • I would feel comfortable around people again and I would be Blessed to not have the Cough and mucus situation.
  • It would be amazing! Talking in front of people and singing in church would not be so embarrassing.
  • I wouldn't have to make sure I had mints, water etc. on me every where I go.
  • I wouldn't wake my husband up from caughing or clearing my throat.

Answers given right after ordering, before taking GR-9.

60 days to find out for yourself

If you're skeptical, that's fair. When we asked one person what made them trust us enough to order, they wrote: "I don't trust you yet. ask that question again after 2 months"

We liked that answer, because that's what the 60 days are for. It's also why this page sticks to things you can check for yourself: the full label, a 60-day guarantee and a real phone number.

Some people also asked how long GR-9 takes to work. Everyone's different, so we won't promise a number of days. Take it for up to 60 days, and if you're not happy for any reason, call or email us and we'll refund your order.

You've spent years working on your throat. It might be time to look a little lower.
