The Claim

Individuals with periodontitis have significantly reduced salivary nitrate reduction capacity compared to healthy individuals, as measured by impaired conversion of 8 mmol/L nitrate to nitrite during in vitro incubation, and this impairment is restored to healthy levels following non-surgical periodontal treatment over 90 days, indicating that oral microbiota composition directly influences nitrate metabolism.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

People with gum disease show a lower ability to convert nitrate to nitrite in saliva, and this ability returns to normal after non-surgical gum treatment lasting 90 days, which indicates that the bacteria in the mouth directly affect nitrate metabolism.

See the scientific wording

Individuals with periodontitis exhibit significantly reduced salivary nitrate reduction capacity compared to healthy individuals, as measured by the inability to convert 8 mmol/L nitrate to nitrite during in vitro incubation, and this impairment is restored to healthy levels following non-surgical periodontal treatment over 90 days, suggesting oral microbiota composition directly influences nitrate metabolism.

Why this might work

Bacteria in the mouth convert nitrate from food into nitrite. In gum disease, these bacteria disappear from the gums, so less nitrite is made. After treating the gum disease, these bacteria return, and nitrite production goes back to normal.

  1. Study: Nitrate reduction capacity of the oral microbiota is impaired in periodontitis: potential implications for systemic nitric oxide availability

    People with gum disease have fewer helpful bacteria in their mouths that turn nitrate from veggies into nitrite, which our bodies need to stay healthy. After getting their gums treated, those helpful bacteria come back, and their ability to make nitrite returns to normal.
