The Claim

Daily dietary nitrate intake for six weeks significantly reduces stimulated P-selectin expression on platelets in hypercholesterolemic adults, but has no effect on unstimulated P-selectin levels.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

In adults with high cholesterol, consuming dietary nitrate daily for six weeks lowers the level of P-selectin on platelets when they are activated by substances like ADP and adrenaline, but does not change P-selectin levels when platelets are not activated.

See the scientific wording

Daily dietary nitrate intake for six weeks significantly reduces stimulated P-selectin expression on platelets in hypercholesterolemic adults, indicating reduced platelet reactivity to activating stimuli such as ADP and adrenaline, but does not affect unstimulated P-selectin levels.

Why this might work

When someone eats nitrate-rich food, bacteria in the mouth turn it into nitrite, which enters the blood and gets converted into nitric oxide. This nitric oxide stops platelets from becoming active when they are triggered by chemicals like adrenaline or ADP, but it does not affect platelets when they are at rest.

  1. Study: Dietary nitrate improves vascular function in patients with hypercholesterolemia: a randomized, double-blind, placebo-controlled study

    This study found that drinking beetroot juice daily for six weeks made platelets in people with high cholesterol less likely to react when stirred up by chemicals like adrenaline, but didn’t change their normal, calm state. So yes, beetroot juice helps calm platelets when they’re being triggered.
