sodium nitrate supplement

A dietary supplement containing sodium nitrate, that can be used for nitrate supplementation purposes. Upon oral administration, nitrate is absorbed by the body and is partially converted to nitrite, which is stored and circulated in the blood, leading to an increase in nitrite levels. Nitrate, and to some extent nitrite, accumulates in saliva and may enhance salivary flow, which may help to treat dry mouth and chemo- and radiation-induced oropharyngeal problems.
