I’ve been excited to share this with you.
For the past year I’ve kept a pack of these mints in my pocket, toiletry bag, and carry-on.
Until now I couldn’t talk about them, but they’re worth mentioning.
At first glance they look like ordinary breath mints. They do more than freshen breath.
These are functional mints designed to support your oral microbiome by feeding beneficial bacteria that produce nitric oxide (NO), a molecule essential for energy, circulation, cognitive function, and recovery.
Many oral nitrate supplements lose effectiveness when they pass into the gut; these mints deliver prebiotic nitrate to the mouth where NO production begins. By nourishing the bacteria on your tongue that convert nitrate into nitric oxide, they support the body’s natural NO pathway.
Why Nitric Oxide (NO) Matters
Nitric oxide is more than a performance aid—it helps keep blood vessels flexible, supports healthy blood pressure, and plays a role in immune response, sleep, memory, and sexual health.
NO production starts in the mouth. The oral microbiome—the community of bacteria on your tongue and gums—is where nitrate is converted into nitric oxide. Modern habits can disrupt that microbiome and reduce NO generation.
Nitric oxide helps dilate blood vessels and improves delivery of oxygen and nutrients to every cell, including the brain and heart. After about age 40, NO levels typically decline, and when they fall you may notice:
• Persistent tiredness despite adequate sleep.
• Brain fog and slower thinking.
• Rising blood pressure.
• Slower recovery and harder workouts.
• A weakened immune response.
You can support NO production by protecting the oral microbiome—avoiding antiseptic mouthwashes that kill beneficial bacteria, choosing microbiome-friendly oral care, and using targeted products that support natural NO pathways.
If you’re traveling, heading into a workout, taking an exam, or competing, try one of these mints. Typical benefits reported include:
• Increased mental clarity as bacteria convert nitrate into NO, enhancing oxygen delivery to brain and body.
• Improved immune readiness via better blood flow and local oral defenses.
• Better circulation as blood vessels relax, supporting heart health and stamina.
• A natural energy lift without caffeine-related jitters or crashes.
• Oral health benefits from feeding the microbiome rather than disrupting it—fresh breath comes from healthier biology, not masking odors.
Here are the steps I personally take to protect nitric oxide production and maintain a healthy oral microbiome:
Mark’s Essentials for Supporting NO
1) Fygg Functional Mints
These mints don’t simply mask breath; they provide prebiotic nitrate to the oral microbiome so beneficial tongue bacteria can produce NO.
✔ Delivers prebiotic nitrate directly to oral bacteria
✔ Supports NO production for energy, focus, and circulation
✔ Helps balance the oral microbiome and supports immunity
✔ Freshens breath by improving the underlying biology
Each mint contains about 62 mg of prebiotic nitrate—the equivalent of a large handful of arugula or roughly 2.5 cups of chopped romaine. Because the nitrate is delivered to the mouth, it’s available to oral bacteria and can be converted to NO within minutes.
2) Magnesium
Many people are low in magnesium, which is important for NO activation and overall cardiovascular and metabolic health.
✔ Helps the body activate nitric oxide
✔ Supports healthy blood pressure and restorative sleep
✔ Aids energy, recovery, and resilience
3) Mouth Tape
Mouth breathing dries and disrupts the oral microbiome, reducing the bacteria that generate NO. Gentle mouth taping at night encourages nasal breathing, helps preserve oral moisture, and protects the microbiome—useful if you wake up tired or with dry mouth.
4) Nasal Care with Xylitol
A separate NO pathway exists in the nose, and keeping nasal passages clear supports overall respiratory and oral health. A xylitol-containing spray can help clear congestion and reduce biofilm that might otherwise disrupt the oral ecosystem, aiding the nitrate-to-NO conversion process.
5) Tongue Scraper
Cleaning the tongue removes odor-causing debris while supporting the bacterial community that produces NO.
✔ Quickly removes coating and odor-causing material
✔ Supports the microbes that kick-start NO production
✔ Helps reduce bad breath and oral inflammation
If you’re over 40, supporting nitric oxide production is one of the most impactful things you can do for energy, cognition, heart health, and overall vitality.
