This extract comes from cacao beans and is standardized for high flavanol content, especially epicatechin. Unlike standard cocoa powder, it contains little fat and no added sugar. The flavanols prompt the body to produce nitric oxide, which helps relax blood vessels. That supports healthy blood flow and arterial flexibility.
People take it to support cardiovascular function and keep blood pressure in a normal range. Improved circulation to the brain also helps cognitive function.
You can take it as a capsule or powder. Flavanol absorption is better when you eat a small amount of carbohydrate, so taking it with a meal works well. The extract is naturally very low in caffeine, though some products might contain trace amounts. If you are sensitive to stimulants, check the label.
