Similar Assertions

When nitrite levels in the blood go up after taking nitrate supplements, blood pressure tends to go down more. The higher the nitrite increase, the bigger the blood pressure drop.

78%

Taking nitrate supplements increases cGMP in the blood, which is a sign that nitric oxide is being produced and working in the body.

When you drink beetroot juice in a cool room, your body produces more nitrite in your blood than when you drink it in a warm room.

74%

Taking nitrate supplements lowers blood pressure, and the more you take, the more your blood pressure goes down. The biggest drop was about 9 mm Hg for systolic and 6 mm Hg for diastolic blood pressure.

72%

Men tend to have bigger blood pressure drops than women when taking nitrate supplements, even though both groups get similar increases in nitrite levels in their blood.
