Compositions of nitrates and methods of use thereof
Inorganic anions nitrate and nitrite influence metabolic rate and glucose homeostasis. Infusion of nitrite iv caused an acute drop in resting energy expenditure (oxygen consumption) and nitrate, when given perorally, caused a reduction in oxygen consumption during exercise and a depression of the increase in blood glucose observed after an oral glucose tolerance test. The doses of nitrate and nitrite did not cause any detectable change in methemoglobin levels of blood. Also, nitrate and nitrite did not alter lactate levels in blood. This discovery provides useful treatments to regulate the energy expenditure and glucose homeostasis of a mammal by administration of inorganic nitrite and/or nitrate.
1. A method of decreasing systolic blood pressure, the method comprising administering inorganic nitrate (NO 3 − ) to an adult human subject.
2. The method of claim 1 , whereby administration of the inorganic nitrate (NO 3 − ) reduces diastolic blood pressure of the adult human subject.
3. The method of claim 1 , wherein the inorganic nitrate (NO 3 − ) is administered in a composition in the form of a liquid, a paste, a gel, a bar, a cake, a powder, a granulate, an effervescent tablet, a chewing gum, a tablet, a capsule, a lozenge, a fast melting tablet or wafer, a sublingual tablet, or a spray.
4. The method of claim 1 , wherein 0.1 mmol inorganic nitrate (NO 3 − ) is administered per kg body weight of the adult human subject.
5. The method of claim 1 , wherein the inorganic nitrate (NO 3 − ) is administered in a composition consisting of the inorganic nitrate (NO 3 − ) and at least one additive.
6. The method of claim 5 , wherein the composition is a nutritional supplement.
7. The method of claim 5 , wherein the inorganic nitrate (NO 3 − ) is provided from a natural nitrate source.
