The Claim
Pomegranate powder at a dose of 1,000 mg contains negligible dietary nitrate (<0.001 mmol per 1,000 mg) and does not elevate plasma nitrate or nitrite concentrations in humans when compared to placebo.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Pomegranate powder at 1,000 mg contains almost no nitrate and does not increase nitrate or nitrite levels in the blood compared to a placebo.
See the scientific wording
Pomegranate powder (1,000 mg) contains negligible dietary nitrate (<0.001 mmol per 1,000 mg) and does not elevate plasma nitrate or nitrite levels compared to placebo, contradicting prior claims that it is a significant source of dietary nitrate.
Pomegranate powder contains almost no nitrate, so when it is eaten, it does not increase nitrate in the blood. Without more nitrate, the body cannot make more nitrite or nitric oxide, so there is no change in muscle performance or signaling related to these molecules.
What the research says
1 studyThis study gave people pomegranate powder and checked their blood for nitrate — it didn’t go up. That means pomegranate powder doesn’t act like a nitrate supplement, even at the usual 1,000 mg dose.
