Interpreting a Low Nitric Oxide Reading on a Saliva Test Strip: Significance and Implications
In recent studies, low levels of salivary nitric oxide (NO) have been linked to the body's immune response to bacterial infections, such as Lyme disease. By inhibiting bacterial replication and disrupting bacterial enzymes and DNA, NO plays a critical antimicrobial role in the immune response.
Several factors can contribute to low salivary NO levels. One such factor is the composition of the oral microbiota. Commensal bacteria in the oral cavity convert salivary nitrate to nitrite and then to nitric oxide. Disruptions or imbalances in oral microbiota can reduce this conversion efficiency, resulting in lower salivary NO levels.
Chronic inflammation and metabolic conditions, such as obesity, type 2 diabetes, and metabolic syndrome, are also associated with altered nitrate-nitrite-NO pathways, potentially reducing NO bioavailability. Lower plasma nitrate levels have been observed in uncomplicated diabetes cases, indicating systemic impacts on NO production.
Nutritional deficiencies can also play a role in low salivary NO levels. Insufficient dietary nitrate intake can decrease salivary nitrate reservoirs, thus limiting substrate availability for NO production in saliva.
Other factors, such as poor oral hygiene, use of antibacterial mouthwash, smoking, or radiation to the head and neck, can damage oral bacteria responsible for nitrate reduction, thereby lowering salivary NO production.
To safely increase nitric oxide production, several methods have been identified. Consuming nitrate-rich foods like beetroot juice, leafy greens, and root vegetables is a safe and effective method to increase nitric oxide production. Beetroot juice supplementation is widely studied and recommended for increasing NO bioavailability through its natural nitrate content.
Maintaining a healthy oral microbiome is another important factor in boosting NO synthesis. Supporting the oral microbiome through the reduction of antiseptic mouthwash use and potentially the intake of probiotics and prebiotics may enhance nitrate-reducing bacteria, thereby boosting NO synthesis.
Physical activity may also modulate gut microbiota and nitrate reservoirs in skeletal muscle, indirectly supporting NO production and availability. Exercise supports endothelial function and NO signaling pathways.
Avoiding excessive use of antibacterial mouthwashes and maintaining good oral hygiene while preserving beneficial bacteria is important for maintaining NO production.
In conclusion, low salivary nitric oxide levels are mainly influenced by oral microbiota health, inflammation, metabolic disorders, and dietary nitrate intake. Safely increasing nitric oxide production involves consuming nitrate-rich foods, maintaining a healthy oral microbiome, engaging in regular exercise, and avoiding factors that disrupt oral bacterial populations. These strategies can help improve vascular and immune health, but should be done thoughtfully with awareness of individual health status and potential risks.
