I’ve been dying to share this one with you…
For the past year, I’ve kept a pack of these mints in my pocket, toiletry bag, and carry-on.
But I couldn’t talk about it—until now.
It looks like a breath mint. But it’s way more than that.
This is a functional mint—engineered to work with your oral microbiome by feeding the good guys to create nitric oxide (NO), the molecule your body depends on for energy, circulation, brain function, and recovery.
Unlike most nitric oxide supplements, which go straight to the gut and lose up to 75% of their effectiveness, these mints start where NO production is meant to begin—in your mouth. They work by feeding the beneficial bacteria on your tongue that convert nitrate into nitric oxide efficiently and naturally. It feeds the good guys—the beneficial bacteria on your tongue that start the process.
Why Nitric Oxide (NO) Is the Molecule You Can’t Afford to Lose
NO isn’t just about energy or performance—it’s your body’s natural way of keeping your blood vessels flexible, your blood pressure stable, and your immune response sharp. It even plays a role in sleep, memory, and sexual function.
And it all starts in the mouth.
The oral microbiome—the community of bacteria that lives on your tongue and gums—is where nitric oxide production begins. But many modern habits are quietly sabotaging it:
Imagine a molecule that boosts energy, sharpens focus, improves circulation, and helps your body bounce back after workouts.
That’s nitric oxide (NO).
Your body uses it to dilate blood vessels, delivering oxygen and nutrients to every cell in your body—including your brain and heart.
But the catch is…
After age 40, your nitric oxide levels start to drop. And when they do…
😬 You feel tired—even after a full night’s sleep.
🧠 Your brain feels foggy and slow.
🩸 Blood pressure creeps up.
🏃 Recovery takes longer, workouts feel harder.
🧗 Your immune system takes a hit.
You can restore it—if you stop disrupting your oral microbiome and start feeding it properly. That means avoiding mouthwash that kills good bacteria, switching to microbiome-friendly oral care, and using tools that support—not suppress—NO production.
If you’re about to hop on a plane, crush a workout, take a test, or run a race—pop a mint. Here’s what happens:
🧠 Clarity kicks in: Your good guys convert nitrate into nitric oxide (NO), boosting oxygen delivery to your brain and body.
🛬 Your immune system gets a boost: Nitric oxide helps your body defend against pathogens by enhancing blood flow and immune response, right from the mouth.
💓 Circulation improves: Blood vessels relax and widen, supporting heart health, stamina, and faster recovery.
💨 Energy elevates: More oxygen means more natural energy—no caffeine crash, no jitters.
😁 Your mouth benefits too: You’re feeding the oral microbiome, not disrupting it. This mint doesn’t just freshen breath—it nourishes the ecosystem that supports your whole-body health.
Here’s what I personally use to protect nitric oxide production and support my oral microbiome:
Mark’s Must-Haves for NO – the Longevity Molecule
1) Fygg Functional Mints
This isn’t a mint that masks bad breath. It addresses the root cause—by feeding the right bacteria on your tongue to produce nitric oxide.
✔ Delivers prebiotic nitrate directly to your oral microbiome
✔ Fuels nitric oxide production for energy, focus, and circulation
✔ Supports immunity and promotes microbial balance
✔ Yes, it freshens breath—but by shifting your biology, not covering up bad breath
👉 Grab a pack of Fygg’s Functional Mints
Each mint contains 62 mg of prebiotic nitrate—the same as a large handful of arugula or about 2.5 cups of chopped romaine. But unlike a salad, this nitrate doesn’t get lost in your gut. It goes straight to the bacteria on your tongue—the ones that turn it into nitric oxide within minutes.
2) Magnesium
Most people are not getting optimal amounts of magnesium—and that’s bad news for nitric oxide production…
✔ Magnesium helps your body activate nitric oxide
✔ Supports healthy blood pressure and deep sleep
✔ Boosts energy, recovery, and stress resilience
👉 If you need a recommendation for magnesium, this is my favorite.
3) Mouth Tape
Mouth breathing disrupts the oral microbiome. That matters because it’s the microbiome on your tongue that drives nitric oxide production.
✔ Trains your body to breathe through your nose
✔ Helps protect the oral microbiome from drying out and dysbiosis
✔ A game-changer if you wake up tired or dry-mouthed
👉 Start mouth taping tonight to support your nitric oxide–producing bacteria. My favorite is Nexcare 3M tape, available on Amazon and in drugstores everywhere.
4) Nasal Spray with Xylitol
There’s a separate nitric oxide pathway in your nose—where enzymes (NOS) convert arginine to NO. But that system declines with age.
The more resilient, age-proof pathway is the one that starts on your tongue. This spray supports the good guys in your mouth by keeping your nasal passages and oral biofilm clear:
✔ Clears congestion with xylitol (not just saline)
✔ Helps prevent nasal and oral biofilm from disrupting your microbiome
✔ Supports nitrate-to-NO conversion by keeping your tongue’s ecosystem balanced
👉 Use daily if you’re feeding your oral microbiome and want to keep conditions ideal
5) Tongue Scraper
Your tongue is home to nitric oxide–producing bacteria—but only if you keep it clean.
What it does:
✔ Removes odor-causing gunk in seconds
✔ Supports the microbes that kickstart NO production
✔ Helps prevent bad breath and oral inflammation
👉 If your tongue looks white or coated, you need this.
If you’re over 40, keeping your nitric oxide levels high is one of the best things you can do for your energy, brain, heart—and breath.
