Treating gum disease helps people with gum problems get the blood pressure-lowering benefits from beetroot juice.

People with gum disease don't get the same blood pressure-lowering effect from beetroot juice as healthy people do.

People with gum disease have more nitrate left in their saliva after drinking beetroot juice, meaning their mouth bacteria aren't converting it as well as healthy people's bacteria.

Drinking beetroot juice in a warm room doesn't make your blood pressure go down compared to drinking a placebo in the same warm room.

Drinking beetroot juice every day with at least 397 mg of nitrate can lower high blood pressure as much as common blood pressure pills do.

Drinking a glass of beetroot juice every day for a month can lower your blood pressure in different settings—like at home, at the doctor’s office, and even when you’re wearing a monitor all day—without your body getting used to it and losing the effect.
