Oatstraw

Research shows that impaired blood flow is a risk factor for heart disease and stroke .

Green oat extract contains a unique group of antioxidants called avenanthramides, which have been shown to improve heart health.

In particular, they may improve blood flow by increasing the production of nitric oxide, a molecule that helps dilate blood vessels.

One 24-week study in 37 older adults with excess weight found that supplementing with 1,500 mg of oat straw extract daily significantly improved measures of blood flow in the heart and brain, compared with a placebo.

While research shows that oat straw extract may help maintain a healthy heart, more long-term studies are needed to fully understand its effects.
