The Claim

Daily consumption of adlay tea for eight weeks increases flow-mediated dilation in healthy adults over 40 years of age compared to placebo, indicating improved vascular endothelial function.

Supports is higher

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

Cause and effect
1 study reviewed
In plain English

Drinking adlay tea every day for eight weeks increases blood vessel function in healthy adults over 40, as measured by improved flow-mediated dilation, compared to not drinking it.

See the scientific wording

Eight weeks of daily adlay tea intake improves vascular endothelial function in healthy adults over 40 years of age, as measured by increased flow-mediated dilation, compared to placebo, indicating a potential benefit for arterial health in middle-aged and older adults.

Why this might work

Compounds in adlay tea enter the bloodstream and block an enzyme produced by immune cells that creates harmful chemicals. This prevents damage to the inner lining of blood vessels, allowing them to relax more fully when blood flow increases.

    People over 40 who drank adlay tea every day for two months had better blood vessel function than those who drank a placebo, meaning their arteries relaxed better — a sign of healthier hearts.
