Nitrite

Nitrite is a form of nitrogen compound found in your body and environment. Blood nitrite levels reflect metabolic processes and can indicate nitric oxide metabolism status, which is important for blood vessel function and blood pressure regulation. Nitrite testing may be useful in assessing cardiovascular health and endothelial dysfunction. Elevated nitrite can result from high dietary intake of preserved meats and processed foods, while low levels may indicate poor vascular function or disease. This marker is emerging in research on cardiovascular and metabolic health.
