NO Functional Mint FAQ's

Fygg Nitric Oxide Functional Mints are slow-dissolving lozenges that deliver prebiotic nitrate directly to your oral microbiome, promoting natural nitric oxide (NO) production for better blood flow, immune defense, and fresh breath.

Most NO supplements go straight to the gut and quickly bypassing the oral microbiome — reducing the “hang-time” that has been shown to increase the effectiveness. Fygg Nitric Oxide Functional Mints immediately activates nitric oxide production by feeding the oral microbiome prebiotic nitrates and vitamin C in a slow releasing mint lozenge allowing the good nitric oxide producing oral bacteria to increase, generate nitric oxide while reducing the bad bacteria associated with cavities and inflammatory disease.

Yes. The ingredients in Fygg Nitric Oxide Functional Mints (prebiotic nitrate, vitamin C, polyphenols) are supported by published research here. Additional studies have been
completed and are pending publication here.

Yes. Fygg's NO mints are food-grade, natural ingredients and comply with the Acceptable Daily Intake (ADI) for dietary nitrate.

Fygg NO mint are formulated for adults. For children, consult your pediatrician.

Avoid mouthwashes and toothpastes with antibacterial agents like chlorhexidine, which can destroy helpful bacteria. It is best to combine the Fygg Nitric Oxide Functional Mints with Fygg Toothpastes that feed the good guys, further improving the overall health of your oral microbiome.

The optimal time to take a nitrate lozenge is first thing in the morning—right after tongue scraping and hydration. That’s when your oral environment needs a touch up: saliva flow is reestablished, ionic balance is restored, and the oral microbiome is reset and ready to metabolize nitrate efficiently. It can also be beneficial at other times of the day as well. Please speak with your medical team before starting any supplements.

Great but pricey
